| Pros: | Inexpensive, compact, sharp centers, fisheye effect, a little wider than 16mm | | Cons: | Huge exposed front element, inconsistent build quality | |
Overview - Overall, a great inexpensive wide angle prime lens, I'd especially recommend it for people looking for a wide angle on a budget or interested in playing around with the fisheye effect before committing on a high dollar lens.
Build quality - If you get a good sample, the lens is pretty well built, with a metal lens barrel, nice heft (without being heavy) and smooth focusing. It is suprisingly compact, shorter than my FA 35/2 with hood. If you have soft images at infinity, the infinity stop can be adjusted in one way or another by peeling back the focus ring, loosening (but not removing!) the screws and resetting the focusing ring a little left or right. I adjusted mine to give about 1 mm more towards infinity focus, and I got marginally sharper images. I doubt every lens needs this adjustment.
Sometimes the lens hood will also need adjusting if it is crooked or bumping up against the focusing ring at infinity.
Image quality - Properly focused, the images are impressively sharp for such an inexpensive lens. Reports vary online as to what the sharpest apertures are, but I usually use mine around f5.6 and get very nice results. The extreme corners can get a little soft, but I never put anything important in the corners anyways. The fish-eye effect is a little more subtle on APS-C, and you can manipulate it in camera with subject and angle placement, or you can clean it up in post-processing with lens correction. Effective focal length seems to be a little wider than the 16mm spec, which is nice. There is a bit of a warm cast, which is fixable in post-processing.
Usage tips - Focusing can be hard with this lens, both because of the wide angle of view and the short focus throw. I will usually either start and/or end focusing by checking the distance scale on the lens to make sure I'm in the right ballpark. Also, there is virtually no shading of the front element, which can lead to flare and poor contrast in sunlight. I'll often try to shade it with my hand to get more contrast out of the lens. One of these days I will try to rig a homemade hood for this guy.
Value - They aren't quite the value they were a few years ago, now it seems like they are floating around $200, however that's still a couple-few hundred dollars less than brand name primes, with comparable image quality.

| Pros: | Sharp, Wide, Fun to Use, Light Weight | | Cons: | Flare, Green Button, Had to be Adjusted | |
This is a great little lens to use, I bought it about 2 months after my K10D and when it arrived I was very dissapointed, it was very soft all over. After a little research here and a trip to buy a tiny screwdriver I adjusted it so it could focus to infinity (before the infinity distance was about 28 inches). Don't be afrait of it, it is a VERY simple operation to fix the focus so it is smack on.
The lens it very sharp, at f8 and for some reason it is better at close distances than infinity. I have a Vivitar S1 105mm and it is comparable in the centre at ranges of 3 to 8 feet. But I have shot some things at f2.8 and it is certainly no worse than my FA50mm 1.4 wide open.
I often set it at the hyperfocal distance and just fire away without focusing, the DOF is so large that you catch almost everything with it at f8-f11.
The contrast isn't typical Pentax lens quality, but it punches up will in PS, there is enough edge detail that it responds very well.
The one major downside is it tendancy to catch flare, with such a huge front element thats not unexpected. But when it does it produces quite a nice lens flair, there aren't too many elements so it is very simple. Quite like what you see in alot of old movies. I have a very nice 24" x 36" print of a forested creek with sun streaming though the trees a very artistic lens flair accross it on my wall.
The distortion is very natural, in most images, I don't try to correct, only if there is a very obvious strait line will I run it though a batch process in PS.
However, in the end I got a very unexpected X-mas bonus and purchased a Pentax 12-24mm which is more flexable, but cost me close to 4 times the price. And since my wife truly hated the Zenitar, she couldn't remeber to push the green button first, she blessed my purchase.
I definetly recommend this little lens, it's sharp, small and fun to use, and the distortion isn't noticable on most images.

My Serial Number (for reference): 070354
I purchased my Zenitar 16 as a low-priced wide-angle solution for use on my K10D. I was also intrigued with the idea of shooting a fisheye on my 35mm film camera. The decision to buy was not an easy one due to reports of poor quality control, defective coatings, and poor flare resistance (see above review). What pushed me in the direction of purchase was viewing the extensive gallery of great images posted on Flickr taken with this lens. Now that I have had the lens for almost a month, I think I know it well enough to do a review.
What Comes In the Box
While not everyone will be purchasing this lens new, it might be helpful to know just what shipped with a MC Zenitar 16/2.8 in 2008.- Lens
- Instruction book (In Russian)
- Proprietary lens cap
- Zenit-brand back cap
- Nylon fabric padded bag/case with strap
- Four (4) rear-mount filters -- red, green, yellow, and clear (attached to lens)
Note: The rear-mounted filters are part of the optical system. One should be mounted at all times. Take care that lenses purchased used include at least the clear filter.
Build Quality
Much has been made of build quality and manufacturing issues with this lens. The Web is full of accounts of mis-aligned parts and lenses that failed infinity focus. My general impression is that the Zenitar 16/2.8 is built as well and maybe even a little better than most "off-brand" Japanese lenses from the 70's and 80's. In fact, the general feel and smoothness of the controls is much better than my Pentax-A 50/1.7. (Granted, many of the Pentax-A lenses suffer from legendary poor construction, but that belongs in a separate review...) So here are the summary points:
Pros- Solid feel
- Painted surfaces are well-finished
- Relatively smooth focus and aperture operation
- Lens coatings appear to be evenly applied
Cons- Poor manufacturing QA. The first copy I took delivery of had inoperative focus ring, aperture coupling and mount and was returned as defective. The replacement unit could not attain infinity focus and required adjusting the focus ring
- The aperture coupling mechanism makes a strange noise when focusing in/out...go figure... (Note: noise went away over time)
- Metal mount surfaces are rough and poorly finished
- Aperture ring sounds/feels clunky when rotated
- M-42 versions lack the auto/manual switch that allows full use of manual aperture. The M-42 version is NOT RECOMMENDED for use on a K-mount body!
Usability/Handling
The Zenitar 16 handles nicely and is well-balanced on both my K10D and on my film body. Like most non-A lenses, exposure metering is variable in stop-down manual mode on the K10D. This is, however, a problem with the camera and not of the lens. My experience with this lens is that metering on the K10D is fairly accurate from f/5.6 to f/22 with a tendency to overexpose about 2 stops at f/2.8.
While managing exposure is fairly easy, attaining accurate focus was an entirely different matter. Most of my initial test shots were soft, soft, soft due to focus issues. The lens has a very short focus throw with the full range of 0.3m to infinity managed in only about 60 degrees of arc. The short throw along with the appearance of objects in the view finder (everything look so tiny...) made it very easy to be off on the focus of subjects in the range of about 1-2 meters. With time, I learned to make it work, though things would be so much easier if I had a split-image focus aid on the K10D. Note: Since the date of this review, I did purchase a Katz Eye screen with split image. It made a world of difference.
Note: The great DOF at this focal length (1m to infinity at f/5.6) helps somewhat with the focus, but as most of us know, being within the hyperfocal range is not the same as being in focus.
Pros- Relatively compact (not a whole lot larger than many 50mm lenses)
- Relatively light
- Smooth focus
- Aperture ring has definite detents at 1/2 stop intervals
- Fast f2/8 aperture provides bright viewfinder image
- Well-balanced when mounted on the camera (both K10D and 35mm)
Cons- Short focus throw makes fine focusing difficult. This is less of a problem with the split-image screen on my film camera.
- Front element surface is not well-protected
- No provision for front-mounted filters (typical for lenses of this focal length)
- Dark green DOF scale difficult to read
- Proprietary lens cap seats poorly and is prone to fall off.
Optical Performance
I was pleasantly surprised by the optical performance of the Zenitar 16/2.8 on my K10D. My perception is that it is a little sharper than my Pentax 18-55 kit lens wide open and much better at smaller apertures. Performance falls short of my Pentax FA 35/2 in both sharpness and contrast, but that is not surprising given the excellence of the FA 35.
Despite reports on other reviews, I have had little problem with flare and have even shot directly into the sun with reasonably good results. It may be that the coatings used in current manufacture have been improved over earlier versions. The only flare issue has been the rare little "cone" from strong oblique light.
Chromatic aberrations are common in ultra-wide angle lenses, though to its credit, with the Zenitar 16, these are generally pretty well-controlled. The exception being a tendency to exhibit purple fringing (PF) under certain circumstances on the K10D. I was pretty disturbed by this until I compared my results to examples posted by other forum members on the "Fisheye Fever Club" thread. Compared to other lenses of higher pedigree/price, the Zenitar holds up pretty well in regards to PF and overall performance. (Out of respect for the owners and the high prices they paid I will refrain from mentioning the lenses!).
Edit: I recently purchased a K-3 and used it in the field with the Zenitar this last weekend. I was pleasantly surprised to find that the Zen is up to the "K-3 Challenge" and is a very usable optic on that camera.
So in summary:
Pros:- Good sharpness, particular from f/8-f/16 Note: After adding a split-image focus screen to my camera, I found that perfectly acceptable results could be had at f/5.6 as well
- Good resistance to flare for this focal length
- Relatively low CA and PF for this focal length
Cons:- Contrast is somewhat lower than more expensive alternatives
In summary, I would not hesitate to recommend this lens as a less expensive alternative to the main stream wide-angle options on a digital APS-C body. On the 35mm format, the Zenitar is just plain fisheye fun.
Better than average performance, adequate build, low price. What more could you want?!
Edit: I came recently came across this lens of very similar design and much more respectable pedigree.

| Pros: | inexpensive, good optical quality, very high "fun factor" | | Cons: | none | |
Having grown up during the "cold war" era, there is just something ironic and rewarding about owning something made in Russia. The fun factor alone makes this lens worth having. There are other 16mm options available to us Pentax shooters now, but all of them are at least three times more expensive.
The lens comes with several colored filters. These are for use with various films. For use on digitals, be sure to insert the clear filter. It is a must that one of the filters be installed. Also, take care that the lens does not "fall apart" on you. Mine came lose one day and almost came completely undone. Just hand torque it back down and you will be fine.
You will have to shoot in manual (M) mode as well as focus manually. With such a wide angle, just about everything will be in focus anyway. Decent optical quality wide open too. This is a landscape lens. You won't be doing much macro work with this one. Forget filters too. No way to mount one.
For what it costs, it is a great lens to have available in your bag, if for the fun factor alone.

I don't expect to get any fantastic quality images with this lens (especially on the edges); however, it certainly is a lot of fun.

| Pros: | lightweight, cheap good image quality | | Cons: | see text | |
I've been happily surprised by the results with this lens, and would recommend it to anyone looking for a super-wide-angle lens for the Pentax DSLR's.
I was looking for a manual-focus lens as I mostly use older SMC manual lenses, and found this to be my only real affordable option. In this lens I've found an equivalent to a 20mm wide angle lens -- one of my personal favourites in the 35mm film world.
Some sample pics:

http://emuu.net/a/?200703/200703084030a.jpg
I've found image quality to be quite satisfactory, and would summarize my results as:
-good rendering without excessive "fish-eye" look
-good colours and contrast
-easy to use
-lightweight
Some caveats:
-flare is vicious
-the coating on the front element on mine is unevenly applied
-the coating is very sensitive -- I marked it with a lens tissue!
-the front element is extremely soft and susceptible to scratches
-the lens cap is feeble and tends to fall off
To address the caveats above, I made my own hood with a 58mm filter fitting.
Followed the advice of some other users, I put some grippy fabric tape around the very small hood on the lens. On top of this I fitted some nested step-up (67mm -> 72mm) and step-down (72mm -> 67mm) rings. After three of those, I fitted a 72mm -> 58mm step down ring. This covers part of the glass but doesn't impact the small sensor size in the DSLR.
Here are some photos.

| Pros: | very sharp, low price, inexpensive, full frame | | Cons: | Soft wide-open, | |
I purchased this lens a few months ago, and was initially amazed at how sharp and contrasty the images are. I have compared this lens to my Sigma 10-20mm, a Pentax DA14mm, and at 16mm on my Pentax 16-45/4 lens. From f/4 to f/11 the IQ is wonderful! I continue to be impressed with the sharpness of the images from this lens.
Since this is a full-frame lens, it can be used on a K1000 film camera or one of the many Pentax DSLRs. On my K10D, the image is a bit more that 90 degrees from side to side of the frame. It is a fully manual lens, so using it on a DSLR will take a little practice if you haven't used a manual lens before.
It is a full frame fish-eye lens. Which means that is will exhibit some distortion on the K10D. Using PTLens, most of the "fish-bowl" distortion can be removed. The result is a very wide, sharp, contrasty image.
I have considered selling this lens many times, and even listed it on the Marketplace once. But after thinking about it, I couldn't let it go.
This is one of the finest super-wide lenses in this price range. I feel that it would still be a bargain at twice the price. I rated it a 9 because it is so very sharp, and it is worth far more than it sells for. If it was an "A" (auto-aperture) lens, I might have rated it a 10!

| Pros: | sharp, high contrast images, low relative price | | Cons: | some CA at edges, proprietary lens cap, some build quality issues | |
The Zenitar 16mm 2.8 is a low cost solution for wide angle shooting. The images are usually very sharp, with very nice contrast and color reproduction. The lens can be slightly soft wide open, but not so much so to limit it's use in low light. Sharpens up nicely by f4. While you won't get huge distortion on a digital camera, it IS a true fisheye so expect to use something like PTLens to correct image errors.
The lens is available in M42 and Pentax K mounts. It is fully manual control.
There is documentation on the web regarding a build error on some copies that will not allow focusing at infinity. This is a correctable error if you're handy with jeweler's tools and follow some calibration steps on the web. My copy did not show such issues, and I don't think it's wide-spread.
The lens has a "built in" hood consisting of two small petals. I am dubious about their effectiveness, but since I expect some flare with a fisheye, it's not a bother. The hood has a proprietary snap on hood. Don't lose it, you're not going to find a replacement at the superstore.
The cool factor of a lens with Russian script is great, but a fish eye at a small fraction of name-brand counterparts makes this lens a must-have for your kit.
