Panasonic Lumix DMC-TS1 12MP Digital Camera with 4.6x Wide Angle MEGA Optical Image Stabilized Zoom and 2.7 inch LCD (Green) Review

Panasonic Lumix DMC-TS1 12MP Digital Camera with 4.6x Wide Angle MEGA Optical Image Stabilized Zoom and 2.7 inch LCD (Green)

I have been using DSLRs for several years, and currently use the Canon 40D and a wide selection of lenses. I bought this camera as a pocket camera that is easy to take anywhere, and for its HD video capability, as I'm currently in Thailand for several weeks doing some geology research for my master's thesis, and it's impractical and annoying to lug around my big camera everywhere. Therefore my expectations may be different - I am not expecting perfect image quality, full manual controls, etc., because I have my other camera for that kind of thing when I want it. I'm not sure that I would want this as my only camera, because the image quality isn't perfect, but if I didn't have a DSLR I don't think I would notice.
In any case, the main thing I have been using this for is taking HD video. This is excellent, and looks phenomenal on a computer screen. I haven't tried playing it on a TV but I assume it would look excellent there too. It is 720p, not 1080p like the new DSLRs will do, but it still looks great - surprisingly great, even, considering the size of the camera and its lens.
Others have apparently had trouble using the AVCHD Lite codec, but I have not. I can import the .mts files flawlessly into the Kdenlive video editor on OpenSUSE Linux 11.2 with KDE 4.2. I'm not sure what the status of this codec's support in the popular Mac and Windows video editors is, but if you're using Linux, don't worry about it because it works great and the quality and file size are much better than using MPEG2. As it's a small camera with a small lens and few manual controls, video is not going to look like that from a professional camcorder or from a new DSLR with HD video, but it's easily as good or better than that from the small sub $1000 HD camcorders that are available. Manual control of exposure compensation and ISO for video isn't apparently possible - a workaround is to use the scene modes, which works decently well. The night scene modes give pretty good high-iso (i.e. grainy) video at night, even in dark bars and clubs (or here in Thailand, riding in the back of a tuk-tuk). I really like that there's a dedicated movie button - you can immediately start recording a video no matter what else you're doing on the camera by hitting the button.
The camera's responsiveness is very good - obviously not like a DSLR, but much quicker than I'm used to from point and shoots, including other recent models that I've handled. You don't get full manual controls, but if you know what you're doing you can almost always get exactly what you want out of it. I usually leave it in "Normal Picture" mode, which gives you the most manual control. All other modes will either default to use the flash if the camera deems it necessary (which, as in most point and shoots, is almost all the time apparently), or will use the built-in LED to aid focusing, both of which are extremely distracting if you want to be discreet (or if you just don't like the look of straight-on flash).
You do have to know what you want to do with the camera if you use "Normal Picture" mode, it's not just point and shoot - but you will get the best results. The "Intelligent Auto" mode works OK - it tries to decide the best scene mode for you based on what it thinks you're taking a picture of. I would suggest just dialing in the scene mode yourself (there are a lot to choose from) as when I was trying that mode it would sometimes choose the wrong thing. That would be the best mode if you wanted pure point-and-shoot action, though.
Image quality is probably about on par with other point and shoots with folding optics. I don't know too much about this as I'm used to my 40D and other DSLR images. It is certainly more than decent for my purposes, though. Impressively, I've been taking high-iso shots without flash in really dark Thai bars and clubs that turn out ok - they are relatively long exposures of 1/2 to 1 1/2 seconds (or more) so I steady the camera on something, and there is motion blur, but I think that adds to the photo. The image noise in these cases is very obvious, but not overly distracting. Don't expect the results you'd get from a DSLR with a fast lens, and you won't be disappointed. Definitely practice your technique in various situations to get the best results with this camera.
Menu navigation is a little strange at first. I am not sure if it is really non-intuitive, or if I'm just used to the excellent navigation on DSLRs. I think users of point and shoot cameras probably have different expectations - most probably won't have a problem with this. Once you get the hang of it it's not really a problem, anyway, but for me it really was strange at first. All the controls you want (all the manual controls available in "Normal Picture" mode) are quickly available by hitting buttons on the back. You don't have to dig through menus to get the the settings you need most often. It's a similar setup to that on the Canon Powershot series, and probably other cameras as well as far as I know. I really like the different auto-focus options they give you - there are more options than on my 40D, and similar options to the professional series DSLRs from Canon and Nikon. Obviously, they aren't going to work as well as on those cameras, but I quite like the "1-area High Speed" and "Spot" focus modes, which are very fast and work quite well. Unfortunately there is no manual focus, and in tricky situations it can be hard to get it to focus on exactly what you want - in those cases try "Spot" focus, but even there it doesn't always give you what you want.
Now, of course, the big thing about this camera that calls for the high price - because let's face it, for the specs on this camera it is pretty expensive - is that it's waterproof. This works great and is really a lot of fun. I took it into the cold Pacific Ocean at Newport Beach and it held up great. Taking underwater HD video is a lot of fun. [...] I will have some more videos, from Thailand, up soon as well. I've also taken it in a hotel pool, and it worked great there too. Even if you don't plan on going snorkeling or anything with this camera, it being tough and waterproof is a great feature - I don't ever worry about just slipping it in my pocket. It's the rainy season here right now and I don't carry an umbrella, so I could easily get soaked at any time - I would be very careful with a non-waterproof camera, but don't have to think twice about always carrying this one with me.
Do be careful, though, and be sure to read the instructions - there are some things you should do to take care of it so that the waterproofing holds up. The waterproof seals really could be better than they are, but if you take care of them I think they should hold up pretty well.
One thing you might also want to watch out for is battery life - when I took it to the beach, I only got about 25 minutes of video recording and a few photos before the battery (which was fully charged beforehand) was completely dead. The Pacific is quite cold, of course, which may have been the reason for the short battery life, but it is something to be careful of. Extra batteries are annoyingly expensive, and I haven't seen a third-party version available yet, but I would have to recommend getting one because so far it seems that the battery life is unpredictable. I left it recording video on my desk with a fully charged battery to see how long it would last, and it went about 2 hours (which is about what you can fit on the 16gb SDHC card I got with the AVCHD lite codec). That seems pretty good, but in real life use you will probably get considerably less life out of the battery.
The zoom range is pretty decent; I usually stay at the wide end and I appreciate that they give you the 28mm equivalent - a lot of other point and shoots are at their widest at 35mm, which is significantly less wide. The lens is not exceptionally fast - which I assume is due to the folding optics design - but it normally is fine, even in dark places as I described earlier. I don't really ever zoom in too much, because with the slow lens it's usually blurry except in bright light. The optical image stabilization works well, and is active during video recording (if you want it to be) to remove some of the jitter, which is kind of annoying in videos, and which you'll get a decent amount of with this camera due to its small size.
Macro images are nice - you can get quite close. Be careful about the "Macro Zoom" mode, though - it is actually a digital zoom! You can get much closer, but the image quality really suffers. This looks especially bad if you use it during video. I suggest simply never using this option. The regular macro mode works fine. You can get closest by zooming to the widest setting, which seems weird, but it works.
The camera is pretty stylish and has a nice feel and heft. It feels really well built, mostly metal, and not all smoothed out and boring like most modern electronics design. If you're into gadgets, you'll really appreciate the industrial styling of the camera, and the weight. The screen is very good; it is bright and visible in direct sunlight and will automatically adjust the brightness depending on where you are (if you set it to - you can set the brightness yourself, too). One problem with the design - and one inherent to this type of camera with folding optics - is that you will often find your fingers covering the lens until you get used to holding it. Kind of annoying, but understandable due to design limitations.
Overall - I think this is great as a pocket camera, for its HD videos, and as a backup for another camera. I personally would not want it as my only camera - I would choose my DSLR. I would not hesitate in recommending it to anyone who isn't interested in a DSLR, though, and who wants a tough, neat little camera, great for traveling. To be honest, I've taken very few shots with my 40D, and quite a lot of them (and a heck of a lot of video) with this in the week or so I've been in Thailand so far.

Olympus 50mm f/2.0 Telephoto Macro ED Lens for E1, E300 & E500 Digital SLR Cameras Review

Olympus 50mm f/2.0 Telephoto Macro ED Lens for E1, E300 and E500 Digital SLR Cameras
Average Reviews:

(More customer reviews)
Update 10/2010 - I wrote this review a long time ago but it's still true today. I moved my 50mm from my E300 to my E3 and still get great portraits from it. I bought the macro empty tube for real closeups and the teleconverter as adjuncts to make this more useful - I don't recommend everyone buys those items unless you are taking forensic pictures in macro mode or want a 200mm 35mm equivalent lens. The tube is cheap because there is no glass inside - it moves the lens out for magnification w/o glass. I just wanted to point out that I've been following this lens price and this month its down lower than the past year (where it approached five bills) so now is a good time to buy at 438 usd. Review begins below.
Before purchasing this lens you should read some literature. You don't need to be a lens expert - but know what "MTF" means. MTF is modulation transfer function. It is a qualty by which lenses are judged. The more linear the plot, the better the odds you've bought a winner. Olympus and Cannon both publish their MTF plots of their "BETTER" quality lenses. They don't publish the plots of the "included in the box" lenses. For good reason. You can analyze them on a machine if you have a lab and discover they resemble a rollercoaster and not a horizontal line like you would prefer.
Google MTF LENS modulation transfer function and you'll be on your way - then visit OLY's website and click on the MTF curves on this lens. You'll see why it is so well thought of.
Now let's talk Zoom. Remember your old 35mm camera. If you wanted a closeup, you walked towards the person. A wide angle meant walking backwards, mindful of the pool, traffic, etc. The zoom lens eliminated some of this to the extent of its focal length. This is not a zoom lens. It is called a PRIME lens. PRIME = opposite of ZOOM. It's like that old friend on your first 35mm camera. But with a little under the hood.
This is called a macro lens. That does not mean it only can shoot closeups. It will focus from 6" to infinity. For $35 or so you can buy a 3 piece set of magnifiers from Hoya or Tiffen - they screw on like filters but magnify the image in 1, 2, and 4 diopter power. Like using a loupe to view a stone, they help you see the fine detail. The microprinting in the new $20 bill is easy to photograph with this lens. You can see things not visable to the naked eye with it.
Finally - as I mentioned the focus does cover close up to infinity like any good lens (just unscrew those magnifiers used to photo your stamp collection). But you will see that while most lenses (in meters) will have a readout of 1, 2, 5, 9, 15, 25, infinity in meters - this lens starts way down at 0.22 m (22 cm!) - the next number is about 0.24 m. The point is there is a wide range of focus space down close to the lens below a meter, then 1, 2, 3 meters. For closeups this can't be beat.
This is not to say you can't use this lens like old'faithful on your first 35mm camera. I've shot entire photoshoots with this just stepping back a couple times to frame the shot how I wanted it. I also switch to aperature mode (A) on the Oly Evolt and stopped down the lens to F10 outside or with the FL-50 flash. My depth of field was dramatic - everything came into sharp focus with the crosshairs in the middle.
Printing the images on 24" wide photo paper and a HP designjet drafting/photo printer gave the final satisfaction. This is one awesome lens. No zoom, but pictures so sharp and detailed with contrast unheard of before that when I run out to catch a good photo, this lens is normally on my camera. And I also have the 50-200 ED zoom. The 50 ED PRIME lens will outperform the 50 zoom under most occasions.
It's a starter lens, a quality lens (mid level in the OLY 3 tier quality system), a macro lens, and best of all a razor sharp lens that maintains contrast (you normally give up one for the other). There is a lot of glass inside this piece, and good glass at that. I advise against the f=35 mm macro lens, as it is in the LOW quality group from oly. If you need a 1:1 scale, consider this lens with the extention tube for a little more and you'll be close to 1:1 there.
Like all of the "quality" group of lenses in OLY's lens plan, this has a focus meter on it to tell you where you are focusing, or to aid in manual focusing. Mine spends most of its time on the camera - I'm sure you will enjoy printing photos from it as well. Shoot at F/10 and focus is almost not an issue at all in wide spaces. Inside, add the FL50 flash and shoot F/10 as well. You'll be happy with the outcome.
One last note about flashes - you'll eventually want the ring flash for macro work. Undocumented is that the ring flash includes 4 modeling lights with a 3 minute timer on them. To put the macro ring flash on the macro lens requires a ring flash adapter FR-1 available separately for about $95. It's bucks, I realize, but it does have a simple two prong bayonet mount to a ring cut into the lens - so removing the ring flash is a breeze. The ring flash (minus modeling lights) has a GN of 36 and is roughly equivalent to the FL-36, except that shadows are kept to an absolute minimum since the flash wraps around the lens. I use it for closeups and even modeling shots - a great lens/flash combo with the FR-1 adapter. Using the modeling lights you can keep the flash reflection out of the picture!

Nikon 85mm f/3.5G AF-S DX Micro NIKKOR ED VR Review

Nikon 85mm f/3.5G AF-S DX Micro NIKKOR ED VR
Average Reviews:

This macro lens is usable hand-held in many situations. My Nikon, a D90, is capable of shooting at ASA 800 and above without serious noise. This means I have a few f-stops in hand from the VR and from the ASA. I have spent some time "practicing" in my backyard learning the ins and outs of this fine lens. Prints are 13"x19" so it is rather easy to see and appreciate what this 85mm is doing. The price is right if you are using a DX camera (one with a less than 35mm sensor). Some tips are the following : 1) if your not using a tripod, make sure you are solid, e.g., sit on the ground and/or keep your upper arms glued to your body, otherwise the VR wont help much at close distances, 2) pay lots of attention to focus since close up depth-of-field is close to zilch, 3) use as small an aperture as possible consistent with enough shutter speed to "freeze" the picture-count VR for a stop or two, 4) remember when you are up close outdoors there is a very good chance you shadow is in the way-either move or wait until the sun has moved. Finally enjoy discovering a world of fascinating color and textures surrounding you that you might have escaped your attention before you had this tool to use.

Sigma 105mm f/2.8 EX DG Medium Telephoto Macro Lens for Canon SLR Cameras Review

Sigma 105mm f/2.8 EX DG Medium Telephoto Macro Lens for Canon SLR Cameras
Average Reviews:

(More customer reviews)
When I first started looking for a mid-level macro lens, a few weeks ago, I was naturally drawn first to the Canon 60mm, as I have already have 2 Canon bodies.
But then I started looking around, reading reviews (mostly on Fred Miranda's site), and comparing prices. The more research I did, the more appealing this lens became. And finally, I decided to go with it.
Here's why:
- The price is similar to the Canon 60mm.
- I already own a Sigma EX-series lens (17-35mm), and really like it. I like the matte finish, and the glass is excellent.
- For some reason I cannot fathom, Canon doesn't include lens hoods with any of the mid-range lenses I looked at. Sigma does.
- The greater focal length means I can stay farther from the subject - minimum focus distance is about 30cm (12in). This is almost always a benefit.
This lens isn't perfect, however, and here's a few caveats you may want to consider before making a purchase:
- In low light (ie, most macro photography), this lens likes to hunt. Which can be a slow process considering its length when fully extended. Personally, I don't mind manual focus all that much, so this doesn't bother me.
- This is a not an HSM (Sigma's version of USM) lens. It is motor-driven. This might bother you, but I barely even notice it.
- Switching to/from manual/autofocus mode is a 2 step process. Beside the switch on the side of the barrel, the focus ring requires a push-pull motion which is sometimes a bit tricky. With a little practice, this becomes less and less of an issue - and if you leave it on manual most of the time (as I do), you seldom have to worry about it.
- The lens hood is a screw-in, not a twist- or clip-on model. This is, however, offset by the rather deep recession of the glass in the lens tube. (If you want to use the lens hood and leave it on, a 77mm lens cap will fit it.)
Despite these (in my opinion, very minor) problems, I'm very happy with this lens, and would definitely recommend to anyone looking for a mid-level macro lens

I am professional photographer specializing in botanical and nature photography. I bought the Tamron 180 lens after many years of using the equally great 90mm macro. I love the 90mm but was looking for a lens with greater working distance and better ability to control backgrounds. The 180mm has proven to be excellent optically as well as ergonomically well designed. The light weight, for its size, coupled with the very intuitive af-mf push-pull design are great in the field.

Canon EF 180mm f3.5L Macro USM AutoFocus Telephoto Lens for Canon SLR Cameras Review

Canon EF 180mm f3.5L Macro USM AutoFocus Telephoto Lens for Canon SLR Cameras
Average Reviews:

(More customer reviews)
May I introduce you to one of the least know and yet most superb lenses Canon makes. You probably even stumbled on to this page by accident, looking for another Canon lens, looking at various macros, or even just intrigued by this higher-priced lens you've probably never even considered.
Let me just say this about this lens: Ultra sharp. Ultra colorful. Ultra contrast. Ultra solid.
Like everybody else, I initially bought this lens for its macro. The 60mm and 100mm options were a lot cheaper, but my collection is entirely L-class and I'd learned to trust putting gobs of money into the lenses with the red ring. So I put my money where my L-faith is and went with this lens. Needless to say, my faith was rewarded again.
Yeah, sure it's got the 1.0x macro capability, and this is important. But what I wasn't expecting was the image quality. It is unbelievably good. Now I'm not somebody who's taking his first trip into L land and comparing this lens to the $300 run-of-the-mill glass. I've used six L-class lenses significantly and I'm comparing this lens' image quality to THOSE.
You will find yourself using this lens as much as its 180mm focal length and f/3.5 aperture dictates. The lens is versatile both as a super-fine telephoto and as a 1.0x macro.
The macro capability is the main feature. 1.0x macro literally means that a 35mm wide object will completely fill a 35mm frame. Basically, it's a small microscope. If you dare to dial in the aperture to the wide-open f/3.5, the DOF is approximately that of the thickness of two sheets of writing paper at 1.0x. Needless to say, you'll need a tripod, preferably with macro rails that slide forwards and rearwards for ultimate control.
(For those of you new to macro, focusing the lens changes the magnification factor. So as one focuses the object, the object's size in the viewfinder changes. This is why I mention the macro rails, they allow you to achieve focus and physically move the lens/camera in and out to reachieve the desired composition.)
As a telephoto, due to this lens' superb image quality, it actually produces images of a much greater quality than the 70-200mm f/2.8L IS. (I know firsthand, as I own it too) The difference is in the 70-200mm's versatility. If the light drops too low, the f/2.8 and the IS bests the f/3.5 quite rapidly. If the distance of subjects change quickly or you are unable to move your feet to frame images, the 180mm will be too constricting and the zoom will win. But under conditions where the 180mm f/3.5 can perform unhindered (such as at an airshow or out flower hunting), it will consistantly produce brighter, more saturated, and sharper images than the 70-200mm F/2.8 IS.
There is a complaint that circulates about the slow speed at which this lens autofocuses, expecially annoying when trying to be used as a telephoto. This is actually incorrect. The lens' autofocus drive does infact move very quickly, but it must traverse all the way from infinity to about 4" in front of the lens to find the subject. This is where the wait time comes into effect. Here's the solution: utilizing the AF limiter switch allows you to limit the AF search to only between infinity and about 5' in front of the lens. Consequently, this range is about 10% of the focus range (the other 90% is in between that 5' and the 4"). I no longer experience AF "hunting" problems when trying to use the 180mm as a telephoto.
Some other info about this lens:
The front objective element is actually concave. I think this is the only L lens Canon makes with a concave front element. It's probablyexpensive to replace if an accident should occur, so utilize a UV filter (72mm filter size). I recommend only the B+W or Hoya Multi-coated brands. (Yes they're pricey, but worth it)
The hood for this lens is actually a little too small in my opnion. If shooting a backlit object, I sometimes get the heavy orange glow in the viewfinder soI am forced to use my hand as a "hood extender" and block the sunlight.
For its size, this lens is relatively lightweight. It is much lighter than the 70-200mm F/2.8L IS and easily handholdable for extended periods of time.
This lens is compatible with Canon's extenders. I have personally used it with the 1.4x extender. The results are excellent. While CA and sharpness degrade noticeably on the 70-200mm, this lens shows barely a difference in image quality, except for the change in designation to a 252mm F/5, of course. And add to the fact that the macro capability is now gone from 1.0x to 1.4x, a big bonus.
So for whom does this lens apply?
-Those who neither have a macro or a telephoto prime who desire a single piece that can handle both aspects with excellent results.
-Those who plan on performing professional product photography.
-Those that are looking into serious nature photography (packing this lens with a wide-angle is pretty much all you'll need on a day hike).
What this lens does not do well:
-Low-light photography.
-Event photography.
-Landscapes.
Alternatives:
-60mm/100mm: lesser image quality, less telephoto compression in macro images, no real double-duty as a telephoto, but a whole lot cheaper and wider aperture.
-MP-E 65mm: much greater magnification (5.0x), lower image quality, no telephoto capability, odd design means studio use almost exclusively

I love Canon. Although there were times when I shot with Nikons (D700, D300) and were pretty impressed with the result, I always came back to Canon.
This is the first is macro lens for Canon and they got it right. I have used the 60mm, 100mm, & 180mm macro before and by far this is the best!
Now, if you already own a 100mm macro you should try it before upgrading because the IQ of the lens are identical. I usually use this lens for portraits (yes, I know the 85mm & 135mm is a better portrait lens.) of my daughter and the IS is awesome. Hand holding 1/40 I can still get a sharp picture.
The thing that I really hated about the non-IS 100mm macro was the distribution of weight - it was the most awkward thing to shoot with. This lens feels lighter because of the even distribution of weight and size (gradual taper) and it includes a deep hood.
I know $1K is a hefty sum of cash, but considering what you get and how long it can last you - I don't know why you would settle for the non-IS.
--- Edit ---
I found that for portrait, the bokeh on this thing is incredibly smooth. Instead of the angular blurs (lights, flowers, etc), you get a smooth circular blurs due to its spherical diaphragm. But I guess that's in the eye of the beholder...
