Pros: Excellent build, Very sharp at F:5.6 and on, Easy to focus, No CA
Cons: A bit soft under F:2.8 but net improvement after...

Good lens for Landscape and general City walk-around lens. Soft but nice at F:2.8 but sharp at F:5.6 and very sharp at F:8. All metal lens, feels very solid and works well on a full frame body. Focus ring is smooth and precise. I would recommend if you can find one at a decent price.

Pros: Sharp past f4, cheap, well built
Cons: Very soft at f2.8
Sharpness: 7    Aberrations: 9    Bokeh: 8    Handling: 8    Value: 9    Camera Used: K-s2   

It's a lens that you really need to learn and play with it to appreciate. From the great vivitar 28mm bestiary I think mine is the K03.

It's well build, all metal. The focus ring is smooth, aperture ring clics well. However, this lens only is useful starting at f4. Wide open it's very soft.

It's a bit hard to focus in the viewfinder and it's not because of the ring (which is smooth) is just the way it looks in there is kinda flat. The pictures are not flat though so there is that going.

The more I use it the more I like it. Peak sharpness at f8.

For the price I paid can't really complain.

There is some charm to these old lenses.

Pros: Sharp stopped down to f5.6 - f/8.0, small, easy to handle
Cons: Soft wide open
Sharpness: 8    Aberrations: 7    Bokeh: 7    Handling: 9    Value: 8   

This lens is a Komine build. It was also very well cared for and arrived in its original packing. It showed no blemishes.

The aperture ring clicks solidly into place at each stop. The focus ring is very smooth. It is small and very light weight.

When I first received this lens, I was shooting it wide open and was less than impressed as it isn't very sharp. Even give that, I kept the lens since I needed something wider than a 50mm on a crop sensor.

This last Saturday, I was out taking photos of the local fall color and put it on to give me a wide field of view. Again I was shooting wide open for the first few captures and again it wasn't really impressive! I then was focusing on a brilliantly lit tree and decided to stop the lens down to keep from overexposing. This was an eye opener. You could even see the difference though the LED in live view (I use a Hoodloop as a focus aid). Once I got these downloaded and reviewed them on my large monitor, they were extremely sharp and had lots of contrast. This has changed my mind about this lens. It will spend a lot more time on my camera.

Camera used is a Canon 60D.

Pros: Very sharp and great contract at 5.6
Cons: Soft at all other apertures
Sharpness: 8    Aberrations: 7    Bokeh: 8    Handling: 8    Value: 9   

Very nice little lens, got it together with the smc k 55mm f1.8, vivitar series 1 70-210mm f3.5 and some filters voor only 50 euros, lucky day for me.

The lens is soft at almost all apertures, I mainly use it a 5.6, which gives real sharp contrasty images (much better than my smc m 28mm). At night the flare of city lights is very very ugly, so I'd advice to use a star filter.

Pros: its not a write off
Cons: everything else
Sharpness: 6    Aberrations: 7    Bokeh: 7    Handling: 7    Value: 6   

Its worth consulting the "vivitar 28mm bestiary" given the multifarious plenitude of 28mm vivitars.

I'm pretty sure mine is ~ K03 in the list: 28xxxxx.
i've been distinctly disappointed with this. I ran a direct comparison with my pentax -M smc 28mm. I found this lens dull in look and nature: dull looking through the VF, dull in output colours and contrast. Sharpens up OK when stopped down but wide open on every count it was second best.
Although it is of the "solid metal" era its construction is actually cheap and unsophisticated.
I may have got a bad one.

UPDATE comparison with tokina RMC 28mm and Sigma miniwide have reinforced this assessment.

Pros: Good color reproduction, quick f
Cons: Far off focusing a little shaky

Grabbed it at a garage sale on the body of an old Sears TLS, works well with it and I've just been shooting around. Might just be me and the inoperable light meter but far away things seem a little out of focused even when focused on to the correct depth. But it was a steal, and produces great colors and close ups; love the wide angle.

Pros: Great IQ, Quality construction
Cons: No "A" setting

Started taking pictures and the closer I look at the pictures, the more I want to say 'oh!'. Works well with K-r.

Pros: Good IQ at f5.6, Superb IQ at f8. Excellent build quality
Cons: Suffers at f16. Hard to find and quite expensive

Please note: Review and comments are merely my opinion about this one particular copy, which I purchased off eBay and tested on an APS-C dSLR.

I bought this lens off eBay. As far as I can tell, with the exception of close focusing capabilities the lens is optically identical to another Komine-made lens; the much sought after KA-Mount Vivitar 28mm f2.8 Close Focus/Wide Angle version.

I’ve been using this lens for over one month now on my K-x, and these have been my observations so far:

BUILD QUALITY: Solid metal construction and appears to be very well built with tight tolerances. Aperture ring snaps precisely into place with one click between all markings. Focus ring is exceptionally smooth and well damped. Front element is non-rotating but does extend out to a maximum of ~8.5mm.

IMAGE QUALITY: Color reproduction is relatively accurate. Images produced wide-open are a little on the soft side but still fairly decent. Purple fringing is also evident though not as bad as I thought it would be. IQ improves as aperture is stopped down particularly at f5.6. At f8, however, lens is quite impressive producing very sharp images with fine details all through entire frame even at 100% magnification. F16, on the other hand, is the lens’ weakest point. Indoor/Outdoor sample shots taken at minimum aperture were under exposed, blurry and rather unusable. Flare seems to be well controlled even with a strong light source just outside of the frame.

CONCLUSION: Out of all manufacturers who produced Vivitar 28mm lenses, this particular Wide-Angle version definitely falls into the “oldies-but-goodies” category. Unfortunately, due to its popularity lens has become somewhat rare even on eBay. If aperture is set between f5.6-f8, lens is capable of producing very impressive images. If manual focusing/aperture settings are not an issue then this Komine made Vivitar 28mm f2.8 Wide-Angle, in my opinion, would be a good choice for a normal prime on an APS-C dSLR. If it weren’t for the poor IQ at f16, I would’ve given this lens a higher score.
