Rodenstock Rodagon 28/4

Topcor Auto RE 20/4 Tokyo Kogaku

Images below were taken with this lens and Sony NEX5

You won't get bokeh thing with this lens, it has 0,3m MFD, Flektogon 20/4 has closer. but this lens sharper I think.

Tokyo Kogaku Topcor RE GN M 50/1,4

I had 135/3,5 of this brand, it's great lens. Curious of famous brand Topcon, I was lucky to get this lens in reasonable price. it has fungus and not mint condition, but I'm happy with it. ebay price is very high of this rare radioactive lens.

I heard this lens was the latest product of real Topcon before Cosina rebranded.

Yashica ML 35/2,8

Yashica ML series lenses are known as the best of Yashica. Some say they build ML Series with Zeiss formula. So this 35/2,8 lens is called poor man's Distagon 35/2,8.
MFD is written 0.3m, not close enough for macro.

wide open, closes distance.

Pentacon 30/3,5 M42

Successor of Meyer Lydith 30/3,5 which I believe improved. specially in Coating. Lydith often prone to lack of contrast and flare too much. Sharpness and bokeh is same.

Meyer optik gorlitz Primoplan 58/1.9 & Schneider Kreuznach Xenon 50/1,9

Non scientific test, just for fun. I like both lenses. All shot in Sony NEX5. edit resize only
1st test, same distance, xenon is wider (50mm against 58mm)

Primoplan

Xenon

In 2nd test, I used closest distance for both lenses. So it was different distance. Xenon has shorter distance, so even it's wider but can produce bigger macro ratio.

I hope you like it.

Rathenower Optische Werk Visionar 77/1.6

Another projection lens, this lens has register flange almost similar to Konica AR lenses. So no infinity in EOS camera. I don't use it for infinity though. good for portrait.be careful, it has very thin dof. all wide open.

Olympus H Zuiko Auto S 42mm/1,2 Pen F

I got the lens few months ago, but focusing ring was wrong and I have no adapter to test.

It's fixed now.

first conclusion; very thin dof at wideopen, but sharp if you can nail focus hehehe

flowers wide open

After some months, I can find what I like in Olympus EPM1, I mean I prefer it than Sony NEX5 (well actually I'm not often using it, because I'm more convenience with tilt lcd of NEX5)
These set was shot with Schneider Kreuznach Curtagon 35/2,8, black one in exakta mount
