After mistakenly posting this first in another forum, I'm re-posting here in MFL forum. After seeing a Komura 105mm post from Nordentro (f/2 version), I have been looking for a 105mm. I tend to like Komura IQ and this one is no different. I found this one on ebay out of Australia - it had a funky mount with no explanation of what it was, but I gambled that an M42 mount I have here would fit (they're interchangeable). When the lens arrived, I discovered that the mount was actually just an M42 adapter of some type and the actual lens mount is M42, so I lucked out. I've taken a few test shots around the yard and find it not razor sharp fully open, but acceptable. There is a glow of sorts like Nordentro reported earlier. Stopping down just a little helps the lens get sharp while still maintaining good bokeh - or at least bokeh that I like. I'd like to do a few portraits if I can get my daughter to cooperate or my dog to sit still. Here are first shots:

Beautiful pics, looks like a very special lens, you should try shooting some portraits with it.
Are Komura lenses sold under other brands? Can't say I've ever seen a Komura branded lens. Promura, yes, but Komura, no. In fact, I have a Promura 4.5/300 I need to take apart and clean. If Promura is a rebrand of Komura you just motivated me to get the screwdrivers out. _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |

Don't buy one for sharpness alone. I doubt it's as sharp as Jupiter (I don't have Primotar). I just happen to like Komura as a package - IQ, handling, build quality.
In fact, I am having trouble with this lens that I do not yet fully understand. Too many of my pictures are lacking sharpness and also seem to have a strangeness about them. I wonder about refraction, except I only use down to f/5.6. I cannot yet tell if it's a focus problem, infinity, or something more sinister. _________________ Regards,

With my 135/2.3 komura I saw strangeness when I attempted to use it on an ES-II, but so far it's been fine on a K100D. _________________ -Jussi

What's so sinister about it? It's probably an Ernostar type, just like my Komura 80mm f/1.8 (M42). Very soft wide open, but it quickly gets better while stopping down. Also the color definition of the Komuras are very good and your samples show it.

What I implied by my last post is that the problem has turned out to be me. And I think a combination of things... first, it looked as though it focused past infinity, so I have been backing off a tad as I do with most M42 adapted lenses. Problem was that I never confirmed it and just now it proved good at infinity, so I was in error to back off. Beyond that, I had to have been experiencing movement, so I'll have to redouble my attention to that.
Some pictures were so sharp that I was confused at what was going on, but that should have told me it was me, not the lens. To comply with Nesster, here is one strangeness image that was certainly not infinity. The in-focus area looks distorted to my eyes. Movement? Well, it was 1/60 sec. I'm getting too old to still be making these mistakes.
And here's one where I probably made that unnecessary adjustment:

Peter: That 80mm seems to be a no excuses lens. Of course, you do have a way with lenses. I presume it has the many blade diaphragm characteristic of Komura lenses? Thus the bokeh. _________________ Regards,

In my example the diahpragm is perfectly round at all f/stops. Not a star like in your copy.
