The lens (older version 15 blades) came with a Domiplan and a Praktica Nova for not very much. After a good clean I took it out today.
Here are 3 shots of the same subject (Canna iridiflora) from different angles. Pentacon 2.8/135 at f/8 on Nikon D40x with Kood infinity (glass) adapter; RAW capture with moderate PP.

Seems this Kood works fine for close captures. Have you tried at near infinity ? My noname glass adapter performed quite well for close and was horrible for longer distance. _________________ -------------------------------

Colors seem a bit shallow.
From a nikon camera i'd expect a bit more color saturation. Or is it the lens?
I liked the bokeh.
Second photo sharp is right on!

I am aware of the potential problem you describe Attila. I usually use 135s for plant "portraits". However I often take a shot of something in the medium or longer distance as I'm walking home. Here's one from today - it's not infinity but 30 m - maybe.
Full frame - sharpened in reduction - Bicubic Sharper
100% crop - no sharpening
More generally, I find focussing at long distances difficult anyway - with a variety of lenses including the Jupiter 37A with a Nikon mount and the Telear-N, also with a Nikon mount. I had thought about the adapter - when using it - but it could also be my eyesight or technique. I'm not sure how I can do a test which will distinguish between the different possibilities. _________________ John |

I see no evidence of lens adapter did present this lens is not sharper even without adapter. Might be I did never sell my D50 if I did know this adapter exists! Fantastic! _________________ -------------------------------

@Attila - I think that I was lucky when I started my MFLens career. The Kood was the only infinity adapter that I'd heard of when I bought it and I had absolutely no idea how it would work.
@Barata - thanks for your comments. I agree that the second picture is the best. I included the third because of the bokeh. the colours are not right. however the problem is with the editor - ME. After about a year of shooting in JPEG only I now shoot in RAW+JPEG. Unfortunately the camera only allows "basic" JPEGs. These are unusuable because of artefacts but they give me some idea of the colours I might like.
Here's the JPEG for #3 - straight from the camera after cropping and resizing - there's quite alot in in-camera sharpening..
... and here it is after editing - to my taste ...
The colour of the flower is spot-on - on my monitor. Unfortunately I haven't been able to extract this from the RAW file - yet! Perhaps I'll have another go later today. _________________ John |
