Olympus M.Zuiko Digital - Telephoto zoom lens - 75 mm - 300 mm - f/4.8-6.7 ED - Micro Four Thirds Review

I am an aficionado of slow telephoto lenses. They often have half the weight of the fast telephotos of the same focal length. My previous favorite was the Pentax Tele-Takumar 300mm f6.3 lens, which I use on my Olympus E-P2 in manual focus mode using an adapter. Now I have the M. Zuiko 75-300mm f4.8-6.7. My tests show that it is at least as sharp as my classic Tele-Takumar, and so fast in operation that I now use it as my "walking around" lens.The E-P2 does a great job steadying the image at full zoom, but 600mm (equiv) really does benefit from using the camera with some additional support. Sometimes I use it with a monopod, but usually I brace the lens against whatever support I can find. You can use a tripod, but that's not what this lens is for. It exists to be carried, ready for any subject which crops up, or for finding subjects not visible to your naked eye.

The M.ZUIKO Digital ED 75-300mm f4.8-6.7 with a 35 mm equivalent of 150-600mm is the world's smallest and lightest 600mm super telephoto lens. Weighing only 15.17 ounces and measuring 2.76 x 4.57 inches, this lightweight lens delivers excellent portability and outstanding image quality when paired with the award-winning Olympus PEN cameras. The 75-300mm's rear focusing mechanism is comprised of a single-element unit, to enable remarkably fast and nearly silent HD video recordings with sound.

1. I recently purchased this lens for my EP-1 and will put forth some observations about this lens.
* Size: As most reviews of this lens have noted, it's obviously longer than the 14-42mm Olympus kit lens. However, the "how much longer" is only truly appreciated when you mount it on you camera; when you do so, you'll think silently "... hum, this is a bit longer than I thought it would be."But depending on your expectations / purposes for this lens, it may or may not matter. For myself, I knew ahead of time that this lens was going to be overtly longer than the kit lens and thus I was prepared for it. Furthermore, since the 14-42mm kit lens, although smaller, is not a very compact lens like the 17mm pancake, the EP-1 with the 14-42mm is never going to be a combo where I'm going to be able to put it in my large pockets etc... Thus, I would need to carry the EP-1 + 14-42mm in a case etc... If that's the case (and it is with me), having the EP-1 with the 14-150mm is no big deal because it's still compact enough to still fit in my case and it's certainly light weight.
* Build Quality: basically... decent enough--> translation--> overt plastics.Olympus is trying to keep costs down so as to attract as many folks into the micro 4/3 camp. However at some point, please--> make some lens that don't feel like a semi-toy. With that being said, the optics are good and in the end--> it's all about the pictures.
* Focus: One of the biggest reasons I transitioned to this lens from the kit 14-42mm was the annoying way the kit lens had to refocus each time and the in / out movements it had to go through. Everytime I would use the kit lens, it made me feel like I was using some first generation autofocus lens from the 1980s. This lens, although not lightening fast, definitely focuses smoother and quicker than the 14-42mm, which may not be saying much to some folks, but bottomline, it focuses quicker, quieter and "better" for whatever that means.If you have the new 9-18mm micro 4/3 lens, it focuses like that lens.
* Image quality: very good. As with all of the Olympus lens thus far (in the micro 4/3 line), this lens gives clear, sharp, nicely rendered color images etc... I won't and can't go into a technical analysis of the lens, but in general, when viewing the images taken with the camera, most will be very happy with the results. No surprises here.
* Speed: As everyone knows, you can't have everything in life. If you want a faster lens, you're going to end up with a bigger lens... and a more expensive lens... or a lens with a smaller focal length range (which is what I would argue for). I along with everyone else would have liked a faster lens, but this is basically a consumer grade all in one, does everything lens and thus f4 is in line with this kind of product.
2. In summary, this is a very good lens for all Olympus micro 4/3 users who understand and accept the limitations of this lens. Now as wish list to Olympus: please come out with some quality (optically and build quality) lens, esp prime lens.

Panasonic 7-14mm f/4.0 Micro Four Thirds Lens for Panasonic Digital SLR Cameras Review

How can this outstanding ultra wide micro four thirds lens not have any reviews? I'm not a professional photographer, but I can't sit by idly while this lens is denied its proper accolades.
First, an ultra-wide lens is very useful. The difference between 7mm and 14mm is enormous. The broad field of view at 7mm lets you take amazing landscape pictures. At 7mm, mountains are reduced to boulders, and boulders are reduced to small rocks. More importantly, the ultra-wide angle lets you take close ups of objects while preserving their relationship to the objects around them. And most importantly, the ultra-wide angle lets you take pictures in close or cramped quarters that simply would not be possible with any other lens. At 9mm you can sit in the corner of a room and take a picture of the entire room!!! During filming, you can zoom out from 14mm to 7mm to create a dramatic effect that cannot be achieved with another lens.
Second, this is an excellent choice among all ultra-wides. slrgear and dpreview have tested it and found it to provide excellent image quality. It is ideally suited to the Panasonic G1/GH1/GF1 and the Olympus E-P1 because it is the only ultra-wide lens available for micro four thirds that will auto-focus and auto-expose during movies. Auto-focus and auto-exposure are quiet enough under normal conditions that I can't hear them. Auto-focus hunting is minimal. As of firmware version 1.1 (dated 2009/11/25), this lens officially supports auto-focus in 1080p24 FHD movies. It is incredibly light (only 300 grams) when compared to similar lenses in other formats. The next most compact ultra-wide zoom is the otherwise excellent Olympus Zuiko 7-14mm f/4.0 Aspherical Super ED Lens for Olympus Digital SLR Cameras, which costs 50% more and weighs nearly three times as much with the required Panasonic Mount Adapter. And this lens is currently the only native m43rds ultra wide zoom with constant aperture throughout its zoom range (7mm to 14mm). Wow.
Now the bad news.... Flash is problematic. The wide hood at the end of the lens blocks the on-camera flash in the wide field of view that this lens provides and will cast an ugly shadow right in the bottom middle in your frame. So if you take a flash picture with this lens, your picture will have a dark spot in the center bottom where the lens blocked the on-camera flash :( I'm not sure if a hot-shoe mounted flash can solve this problem because I haven't found any that are rated down to 7mm. This is annoying since at f4.0 this lens isn't fast enough for low light photography without a flash.
And finally, my druthers. My favorite use of this lens is photographing tight indoor spaces, where I am always wishing for a faster lens. So I wish this lens was faster, even though it would be heavier and more expensive. But even exactly as it is, I highly recommend this magical lens for confined quarters and for landscapes.
**Update August 2010**
I took the 7-14mm with me on vacation this month and reacquainted myself with its charms. In Santa Cruz, I discovered that the 7-14mm has a magical ability to look around obstacles, and see things that are not visible to the naked eye. Due to an unfortunate seating choice at the Roaring Camp Railroad, all I could see was the back of the Shay locomotive pulling us up Bear Mountain. At 7mm, this lens reduced the entire locomotive to a small part of the frame and the resulting pictures were better than what I could see with my own eyes (see images). The GH1 with this lens is so light that I took a 1080p24 movie of the Dixiana's 20 minute descent HANDHELD. A few days later I used this lens to take aerial pictures of the Bay Area salt marshes. With this lens's huge 7-14mm range, I could frame my aerial shots exactly as I wanted. No other lens on any other widely available still or video camera system can provide as wide a field of view and as excellent image quality in so compact and inexpensive a package as this lens.

Olympus 261505 ED M40-150mm f4.0-5.6 Lens for Camera (Black) Review

Let me first say that I own an Olympus system with two E-3, and several HG lenses. I also have the excellent 14-54 and 50-200 SWD lenses. I bought the E-PL1 with the two lens kit (14-42 and 40-150) to supplement my "big" system to take along on hikes. The complete kit with both lenses weigh about as much as just the E-3 body and the image quality is about on par.

This 40-150 lens is a jewel. It is very light and very sharp if used at f5.6. It compares extremely well with its big brother (50-200), except in contrast which I can correct with software. It matches the E-PL series cameras very well in size and weight and with the 14-42 makes a perfect travel companion, especially for hiking.

M.ZUIKO DIGITAL ED 40-150mm f4.0-5.6 is extremely light, weighing only 6.7 ounces. With a wide zoom range with a 35mm equivalent to 80-300mm, this lens offers versatility and portability.

The M.ZUIKO 40-150mm has two lens elements in the rear focusing mechanism. The focusing mechanism is designed to deliver quiet and precise operation, for an affordable, high quality means to capture your life in still images or HD videos.

It has taken Panasonic a long time to realize the one of the biggest strengths of M4/3 is exploiting the 2x crop factor. They have now done that with the 100-300mm lens. This lens is the equivalent of a 200mm-600mm f/5.6! Wow (In 1:1 Tele Extender Video mode you get a 2.6x extender fro a 520-1560mm f/5.6 equivalent lens). If you check your specs you will see 600mm prime lenses come one stop faster and cost around oh $14,000. That is not a typo. They also weigh 11 pounds. So they are hardly something you would tote around. Now ideally, Panasonic would come out with a 300mm f/2.8 and f/4. Those would be super lenses on the M4/3. However, they would be bigger and heavier than this lens. So this lens is perfect for bright daylight shooting of birds, sports, safari animals. Just about anything you need to reach out and touch.
This is Panasonic's largest M4/3 lens so far and weighs in at 1.14 lbs. To give you a comparison, Nikon's 70-300 mm lens weighs in at 1.6 lbs. Unfortunately at 4.9" long it is not as small as I think it should be. The Nikon 70-300 VR is 5.6" long so not that much bigger and that is an FX lens. However, with that said this is a solid lens with great construction. It is typical of all of their heigh end lenses such as the 8mm Fisheye and 7-14mm wide angle. Something to note is this lens will be unwieldy to use on all the Olympus M4/3 and the Panasonic GF lines.
This lens takes very nice photos and the autofocus is very fast. Especially on the GH2. The Image Stabilization works as advertised.
Overall, if you are looking to take pictures of birds, your kids soccer games, or anything else that you would use a 600mm lens then this is the one to use on the M4/3 system.
As a comparison the Olympus 75-300mm f/4.8-6.7 is smaller and lighter and covers a greater focal range. However, it does not have Image Stabilization as that is built into Olympus cameras. So this would not be a good lens for Panasonic users. Also, I prefer the build and feel of the Panasonic. However, that is my personal bias. Oh the Olympus is $900 vs $600 for the Panasonic.
Update
Now that I have had a chance to play with this lens on the GH2 for a while, I can say this combo is great for shooting wildlife. The GH2 has an Extra Tele Convert (ETC) mode that makes this lens the equivalent of a 840mm (Medium ETC) and 1200mm (Small ETC). When you shoot in this mode you are getting an 8mp and 4mp image respectively. Yes you can crop a picture to get the same magnification. However, by selecting the ETC mode you are more likely to focus to an ultra sharp image on your subject. Also, it saves you 1 step in your work flow and saves space on your computer. So I find the ETC mode useful for stills also.As a down side it effectively makes your sensor smaller so it is not that useful in high ISO situations.
Overall, a brilliant lens and a no brainer if you are looking for extra reach on you M4/3 system.
