Rodenstock Rogonar S 75/4,5

Usually I use this lens without lens turbo, helicoid only.
Recently I attached it on Zhong Yi Lens turbo and NEX5, Here's the results.

Ernst Leitz Elmar 5cm/3,5 enlarger lens & EPM1

I haven't use it much since last time I put it on NEX.
Let's see how it works on M4/3, Olympus E-PM1

Rodenstock Rodagon 40/4 WA & SK Componon 40/4 WA

Rodenstock rodagon series have preset for aperture mechanism which can be set on certain aperture minimum (like Meyer preset), plus switch to change between click or smooth aperture transition.

Schneider Kreuznach componon has preset lever to switch from desired aperture to fully open aperture (like Helios 44-3 or Tair 11A preset), only click aperture no smooth option.

I cannot directly compare these two enlarger lenses because both have different back focus flange. Rodagon is shorter so that I cannot use same helicoid set up with Componon. I have to add m42 extension tube (thinnest) for Componon maximum use.

 Shot comparison in sun light isn't good to judge color, tone, speed etc. Because in seconds light environment changed, so ignore these, I just wanna know how their sharpness at wide open.

Rodagon

My conclusion, Rodagon has better sharpness at wide open, however it has significant difraction at smallest aperture, f22, while Componon has less difraction.

At other aperture opening they perform similar except Componon has almost 5 star shape at f5,6 while Rodagon shaped pentagram. I will show you later.

Cheap Rodenstcok enlarger lens, which performs not cheap in my opinion.

First of all, this is enlarger lens, don't get wrong to LTM version for Leica rangefinder. The mount is same M39 screw, but like other lenses, this one has no focusing ring.

First test with this, it only 1 word. Sharp! even wide open, stopped down, sharpness will improved.

Steinheil Munchen Tele Quinar 135/3,5 M39

This lens is for SLR M39, not M39 aka LTM rangefinder. But it has short register as SLR one. I guess it's for Braun paxette M39 SLR. It's tiny and has MFD 3 meters, too long for common SLR, remind me of Voigtlander super dynarex which has 4 meters MFD.
In My Sony NEX I use extension tube + LTM-NEX adapter to reach infinity. I really like it's compact size and beautiful silver/chrome finish. Everyone will watching it :D
There's one thing that I like about results with this lens, I can see 3D in most of results than other lens, specially 135mm lens.
