I finally got rid of my another Osawa (35-105 mm f/3,5-4,5) and almost did it with this 135 mm f/2,8 lens. Odds went the way that I still got it, and yesterday, while waiting for my son's films to be processed I've run the City of Warsaw downtown with my K2 hooked up willing to use up remaining half of the Equicolor Super G100 film (Fuji packed in Poland) with expiry date printed to 2006-09. Set to ISO 80/64 it works quite well, set to ISO 100 - shows significant grain.

And here are test pictures of a big wall graffiti. It was placed about 20m away, with it's base up 3-4 meters above ground. My eye level is around 1,7m. So the angle of view is rater centered, slightly from beneath.

I'd prefer to use my M-type cameras with split image for this work, as with micro prism itself it is difficult to fine-tune the sharpness. I made only one series of pictures handheld. Shutter speeds went from 1/1000 at f/2,8 - 1/500 at f/4 - 1/250 at f/5,6 - 1/125 at f/8 - 1/60 at f/11 and 1/30 at f/16. Unfortunately f/8 picture got some strange vertical shake that doubled all horizontal lines.

Film was put in standard C-41 process and scanned with Plustek OpticFilm 7600i SE on SilverFast SE v6.6.2r5. Scanned to 7200 dpi, 48->24 Bit Color, 2-pass multiscan, iSDR+AACO engaged in standard mode. No filters no color/contrast/sharpness altering. Minimal cropping to get 99% full frame.

Just a download try on top - test pics on the way.

Sorry, my ImageShack doesn't support files of 20Mb. Got to find some other way of upload.

I like the menel on first pic. Nice color rendition and cool contrast. How much did you pp it ? I'm getting mine tonight for $16 shipped from www.shopgoodwill.com

Osawa - a lens brand I have hardly heard of, except I have an 80-205 4.5 zoom which was reviewed about 1980 in Australian Photography (after I got mine). I recall they found reasonably good sharpness compared with other 3rd party zooms at the time. I really liked it, used it for a few big events.

Does anyone know where there is more information about them? Just curious.

I made to dense scans of my Osawa negatives - resulting in way too heavy jpeg's and problems to upload them to web-page.

I also ended up with SMC-M 135mm f/3,5 and finally SMC-K 135mm f2,5...... and Osawa went as a gift to my goddaughter along with my K100D SMC-K 55 f2, SMC-M 28mm f2,8.

I have a plan to exchange the Osawa back for a bright Soligor 80-200mm f/3,5 and finish tests.
---------------------------------------------------------
As far as I remember - the lens was a top-quality-build with perfect handling, very good image quality - as for a normal 135mm construction: slightly softer wide open, and crisp stopped down a bit - to very good around f5,6-f8.

Color rendition was slightly cooler than SMC-M 135mm f/3.5, but this is rather a SMC-coating plus - not an Osawa downgrade.

These impressions are consistent with my impressions of the 80-205, which claimed MC and macro at 80mm - although it was not dramatically macro like a lens built to be macro.
