Thanks for the welcome, Hasse.
edit: I like this forum for the accent on lenses, rather than systems.

Looks like I have to add that lens to my collection.

Cheers


I just did a search on eBay for Vivitar 28mm f2.8 CF.
Quite a few hits, but one in particular is a mystery to me. It's the SMS version.
refer https://www.ebay.com/itm/Vivitar-SMS-28mm-1-2-8-MC-Close-Focus-Wide-Angle-Lens/302513473629?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649
Everything else looks the same except for the addition of SMS on the front of the lens.

Does anyone know what the letters SMS refer to ?

I've seen it on other Vivitar lenses but I'm still none-the-wiser.

Whoo Turtle PS, I also hit the Buy-now on a Komine 28/2.8 CF MC in OM mount, near-mint and boxed, for 39.95GBP. Just have to be patient with our postal system. If I go bankrupt it's all your fault.



Thanks for the kind words--no way New England beats New Zealand scenery though. There's an excellent webpage devoted to MF Vivitar 28mm here:

http://photografica.robinparmar.com/vivitar28detail.html] The site lists 38 variants of the Vivitar 28mm here: http://photografica.robinparmar.com/vivitar.html I've heard a lot of suggestions for what SMS means, but have not seen the issue settled, definitively--yet. Hope you like your new lens and you share some of your pics with it too. jt

And just arrived in time for Xmas, the Komine 28mm f/2.8 close focus with multi coating, and in OM mount (my preference).
Boxed with all the original paperwork, looking like new old-stock.

Vivitar (Komine) 55mm f/2.8. This is my second copy of the lens. For a while I had gotten out of the interchangeable lens world and was shooting with a couple of Sony compact cameras. Much easier on the back (weight) and wallet but not nearly as much fun so I recently bought a Fujifilm X-T20. I had missed doing macro but the native Fujifilm macro lenses are quite expensive. Instead I found and bought my current copy of the lens. Here are a couple of my first test shots.

I like the 55mm/2.8, fascinated by the way the focus ring turns, and turns, and turns.
Didn't realise how soft it was at the corners.
What aperture were you using ?

I think I was around f/5.6. I think what you’re seeing isn’t softness but rather OOF because both objects weren’t laying flat when I took the photos.

Hey, congrats on a great lens! This small piece of glass will do 1:5 close-focus work--and the lens is soooooooooo light & tiny. On top of that, it provides half-stop aperture detents through f/11, with a full stop jump down to f/16. I really like the flexibility of half stop detents, something my mf Nikkors do not provide. Also, the 49mm filter ring means inexpensive & easily obtainable filters. If you do not already have a hood, be sure to get one because that front glass has almost no protection from the Sun. Ebay sells (particularly Chinese vendors) some inexpensive hoods. And, in case you did not know, if you are shooting on smaller sensors than full frame, you can use longer hoods than the original & still avoid mechanical vignetting.

Okay, so my posted shot with the glass above was a Fx shot, but here are some shots with this little baby on APS-c sensor (Fuji)--Best jt EDIT=I forgot to mention the below pics were only downsized: no sharpening added. jt

[/img] THIS IS NOT A LENS WITH WEAK CORNERS--RATHER, IT IS SHOT WIDE OPEN @ CLOSE FOCUS DISTANCE FOR THE EFFECT CREATED.

Roka, welcome to the thread! Agreed, there is no softness in the corners of this little gem: rather, when shooting this close DOF is so shallow that one almost needs a flat surface to show off its sharpness to the edges. In fact, I own one of these and a Nikkor 55mm 3.5 macro--the Vivitar Komine is much better @ the edges, particularly wide open and stopped down one stop. Too many people simply do not or cannot understand that a focal plane is very finite, and its depth is affected by these 3 things: distance to subject--Aperture (the larger the A the less the DOF) & focal length). jt

No, it is excellent @ the edges--unless this is a damaged lens, which I doubt. You should Google DOF & its interdependence of the focal plane's depth as related to aperture, distance to subject and focal length--and even sensor. Moreover, Roka took these shots on Fuji (APS-c sensor)--edges are all cropped away.

Look @ my shot above, with the Viv 55mm Macro which is done wide open, on full frame sensor: mountain foliage scene with fog--and look @ the one with the woman on the cell phone in foreground, with distant mountains in background--note the focal plane. jt

Happy New Year. Courtesy of the 55/2.8 macro.
