40 cron with 5.5 to 39mm adapter. Unbeatable for IQ, size, build and price IMO. I modified the adapter ring to take the 12526 hood which also makes it look very cool...

Ha, I called Stephen/cameraQuest
But he was Sold Out of those hoods
Thats why I ended up doing adapter sugery :eek: & the other hood ...
:D - H
 
the 40mm FOV is great, but my cameras don't have the right frames, so I play by the "regular" rules (35 OR 50).
I was wondering: since the late M4P's the VF frames are smaller. do you guys use the 35mm frame for your 40? At what distance is it reasonably accurate?
 
Having owned both the Nokton 40/1.4 and a Minolta M-Rokkor 40/2, I kept the M-Rokkor. Personal taste, but I found the OOF areas of the Nokton too busy.

Chalk up another vote for the Rokkor.
 
Have the Nokton 40mm MC and the Rokkor CLE. I prefer the Rokkor.

Neither have particularly smooth and buttery bokeh, but to me the Noktons is a bit on the ugly side. While the Rokkor (although it can be crazy with circular highlights) has more of a deliberate character.

Both are super sharp at f2, but I just prefer the style of the Rokkor. Its a completely subjective opinion, but since getting my Rokkor my Nokton sees little to no use!
 
I had the Summicron-C 40/2 in the past (with my CL) and it was superb. The original M-Rokkor 40/2 was identical in quality. The M-Rokkor 40/2 second revision from the CLE that I own now performs slightly better on flare, otherwise it's much of the same; it seems to be a bit lighter than the earlier lenses. I'm using it on my M4-2 at present.

I also have the Nokton 40/1.4 MC. The bokeh at f/1.4 is a little busy, but at f/2 and smaller it is on par with the above three lenses. I use it mostly on the GXR-M.

Which is my favorite? Whichever one happens to be on the camera I'm using ... !
 
I should also count the 43mm 1.9 Pentax-L as a 40mm lens here. Now this lens is superb, but the Summicron-C is as good.

I use an external viewfinder. I don't find it a problem to switch between the viewfinder and the rangefinder. Once you get used to it it's very quick.
 
I use both the 40mm Rokkor and the 40 MC Nokon. I like both, but if I could only take one on a trip, I will take the Nokon, as it is more versatile with it's f/1.4 aperture. Unlike the equally compact pre-ASPH Summilux, it is actually sharp and contrasty wide open. And unlike the 35mm ASPH, it is still quite compact.
