Kiron 28-105mm F3.2-4.5 Macro (NIB)

Dwain Barefield , Aug 07, 2009; 01:14 a.m.

I have a Kiron 28-105mm F3.2-4.5 Macro, Minolta mount lens, new in the box. Its been sitting in the closet the past 20 yrs. with my Minolta X-700.

I recently resurrected the X-700; bought a couple rolls of film for it today.
Couldn't remember why I purchased this lens. I'm mean to say, I probably could have easily purchased a Sigma, Tamron or even Minolta for that matter.

Is there anyone out there familiar with this particular lens?

Dwain, there's information on this site if you want to have a bit of a search. also the APUG site has some info. http://photo.net/nikon-camera-forum/00LRz1

Kiron lenses were at least as good as Tamron and Sigma 20+ years ago. That lens was also sold as a Vivitar Series 1 lens, back when Vivitar Series 1 lenses were the best 3rd party optics available.

There was some sort of cult following for some of the Kiron optics, but not large enough to ever drive up the price. From memory, they made a nice 7-element 2x TC, and some good fast wide angle lenses - I am thinking 28/2, maybe even 24/2?

28-105 was an attractive range of focal length for the time, when most mid range zooms started at 35mm. Minolta had a very nice 28-85 and 35-70, 35-105, and 35-135, but no 28-105. Plus the Kiron was presumably a lot cheaper than any comparable Minolta offering. In summary, it sounds like a decent lens, but I wouldn't expect to be able to give up my day job by selling it. Might as well use it as long as you can be bothered with film!

In my own Minolta manual focus days I've always lusted for a mid range zoom that starts as wide as possible, and ended up with a Tokina 25-50/4. Awesome lens optically and as small and light as a MD50/1.4. I absolutely loved it!

I had one for a few years in Contax/Yashica mount. Very decent lense but heavy. I sold it and don't miss it.

So far, I've heard from people who have it in other mounts as well as Minolta. Most seem to have liked this lens. I have 50-135 3.5 and 28mm 2.5 Rokkor's, so I may wind up selling it, but then again it may be interesting to play with for awhile.

All of the 28/2.5 Rokkors I have seen have a pronounced yellow/green/brown cast. If you are shooting b&w film and don't mind the lack of finder brightness then it's still a sharp lens. I may try to give mine the light treatment to get the color back to normal. This worked with my 35/2 Canon FD SSC. The 28/2.5 Vivitar Fixed Mount lens was also made by Kino. It's very sharp, doesn't have the color cast and costs very little. There was a later 28/2.5 Vivitar TX lens which was made by Tokina. This is a decent lens but not as good as the Kino made model. When you are using a lens like a 28-105 zoom you need to know your subject. If you are trying to do architectural work you may find it has too much distortion for that purpose. For portraits and general work it might be just fine.

It's a very good lens. We have test results from it in the Kiron Klub. It's also much better than the Vivitar Series 1, 28-105, made by Cosina, for Vivitar.
