Summicron-C 40mm Action

Interesting, Joel. The block diagram helps to understand it. I wish someone would post a photo of the spots.
A local dealer here had an M-Rokkor 28/2.8 for sale that had a very uniform circular donut pattern of small and smaller round dots, that looked like it could have been between elements 2&3 from the front -- sort of like the dot pattern on a CLE shutter but very symmetrical.
I'm still trying to work out what that might have been -- they offered to let me try the lens out but were asking far too much to consider buying it.

Thanks for the photos, Petar. They tell me much more than discussion and it's a fascinating look.

second from bottom? ... strange, some people said to me : It's too dark!
Funny that man is Boba Hammer, official distributor of Efke film for Serbia :)

thank's I hope that
I'll be able to shoot with something wider -
I've spent a lot of time to understand that RF photography gives best results with 50mm & wider

Joe what you have observed is the classic case of white spots on the rim of the front element. Although it looks deep at the second and third element thats just an optical illusion as you gain a magnifying effect as you look through the front element itself. You can see the 2 flat sides on the lens diagram that angle each other at approx 120 degrees. This is where the white spots occur but remember that the front element is round and when you view the spots from the front they will appear as a perfect donut shape.
 
Bumping this up to share two shots taken with a very late Summicron-C
that even seems multicoated. On Reala 100:

No complaints about the bokeh :)

I sold one of these a couple years ago but recently re-acquired one. Both of mine have been stiff focusers but the picture quality is amazing. I currently use mine as the everyday walkaround lens on my MP. Even though it's already super compact, I make mine more so by unscrewing the rubber hood and using a generic metal 39mm screw-in cap. Together it's not much thicker than a Canon G9.

Would a regular screw-in 39mm UV filter work on this lens?
 
Hi, dear friends. All your shots are very nice (Ned and Ferider particultarly). I also own a Summicron C 40 mm f/ 2 and i found that is an excellent performer. I love the 40 mm focal lenght.
Ciao.

So where are the pictures? ;) ;) ;)
 
Well, after spending the whole day shooting my rokkor, I found that I was having problems to make up the 40mm in my head.
It seems it could be easier with a lower magnification viewfinder though....

Well, Mike, my Noctilux thread is doing bad so let's hope it drives the Noctilux prices down ;) ;) ;)

Hey at least you won't get flamed for starting a thread about an expensive lens =)

What body do you use ? I have a M3 and double up the thickness of the 50mm lines help :D Or shooting too much with it so you can immediately recognised its border ( I did it that way, waste quite a bit of film though)
