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

PZO Amar 105/4,5

It's been long time since I bought last enlarger lens. I got very tempting offer. I couldn't resist.
So here it is PZO Amar P105/4,5 with scratch on front coating.
All shots with Sony NEX5+Lens turbo, the combo is great, even on edges.
All wide open except the infinity shot at f8

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.

Rank Taylor hobson 2 inch/3,5

It has very short flange, shorter than other enlarger lenses brand like Rodenstock, Schneider, Leitzat the same focal length. No infinity in Canon DSLR.

This Enlarger lens, as you can see, close enough to real color.
