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.

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

Together it's not much thicker than a Canon G9.
Would a regular screw-in 39mm UV filter work on this lens?

A regular 39mm filter will cross thread, but be snug and stay put without damage.

The elusive series ring is the 'correct' piece, but I think less than a dozen were ever made

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.

For 40mm you might as well use the internal one

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....

What body do you use ? I have a M3 and double up the thickness of the 50mm lines help 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)

I find M2 + 40 to be difficult. M3 and M6 + 40 work well.

OMG I totaly overlooked this thread! The Cron-C was my everyday lens for quite some time now.
It is my only Leica lens and I allways thought highly of it. however the focus action is very stiff and if I need to refocus it isnīt manageable in fast situations...thatīs why I got a VC Nokton 40mm..still trying to figure out if the Nokton can hold a candle to the Cron-C (at 1.4 thereīs no contest but at smaller apertures and medium distance I doubt the Cron-C can be bettered!)

I use the M6 and filed my Lens mount down to get the 35 Framelines. never had a problem with that combination. Now I shoot with my M4-2 and the FL fit nicely too!

my Flickr stream is full of Summicron-C shots but here are some of my faves:











the detail and rendition of tones is simply amazing IMHO.
Which lens gives me the same rendering but better mechanics? guess I have to go for a Summicron-M?! but which version? (VI?!?)

Superb - a decent discussion about these lenses at last. I have the 40/2 Summicron-C and it's the only RFF lens I've ever used - it's outlasted 3 bodies and counting - a Leica CL, a Bessa R3A, and now it's on an M7 (hopefully the last body it will sit on now!), and it was the only lens I used on a recent round the world trip.

The only problem I have is that I find it hard to justify buying a 35mm or 50mm lens to complement it - I mean, is 5mm wider worth it?

The Summicron-C's do have stiff focusing, it seems a trait of this lens. The CLE Rokkor which has a similar rendering and a conventional M cam have very light focus so you may like to switch to one of them instead.

You mentioned you had the 40mm Nokton already? Well in fact at f2 to 4 you should notice that the Nokton has greater resolution and contrast. I would give it a good try before swapping your Summicron for a CLE Rokkor.

thank you very much for the advice Joel!
I have the Nokton for a month now and havenīt had the chance to use as many fine (slow) films with it as with the cron (about 20 rolls with the nokton but mostly 400-1600, only two 50asa) so Iīm still searching for the texture the cron gave me in the Nokton shots.
The handling of the nokton is perfect for me so I really hope youīre right and that itīs as excellent as the Cron (or even better you say! :-) )
Rokkors are very rare in Europe but I seriously think about them! the Cron-Cīs size and weight with my home made Lens cap is soooo right!! the perfect lens for me except focus...Iīll have an eye on the next rokkor crossing my path :-)
thank you again
fred

p.s. just noticed you write CLE rokkor..do CL rokkors focus as stiff as the Cron-C?

True. I just got a like new one, that was stiff since in the box and unused
since many years, and relubed it. Pretty straight forward if
anybody wants to know how ...

My 40mm Summicron's feels pretty smooth without being too loose. Quite perfect really! Here's some images:

all of the 40 summicrons i have owned have also been very smooth and easy to focus.

it is one of my all time favorite lenses!!

these were all shot w/ a dark red filter. films were neopan 1600, t-max (i think 100), and konica infrared (just the building shot w/ black sky).

Great photos.

I will never part with my Summicron C. The best result have been with black and white on the CL or M3 - with which it works well if you use the whole VF frame. Didn't like it quite as much on the R-D1, as it's the FOV I really love, but all the same...

The firmer focus of the Summicron over the CLE Rokkor should not be confused with being rough or unusable, in fact they focus smoothly and silently just in Comparison with the CLE Rokkor which if anything is a bit too light.

Quote:

Again its not a question of not being smooth just the amount of effort required to focus both examples. If your CLE 40 is not lighter in its focus than your CL Rokkor then I suggest it need a simple lubrication. I have owned and handled dozens of examples and all the CLE examples were almost feather touch to focus, the CL version although smooth were always firmer. I quite prefer the firmer action actually but each to his own.

Minolta 40/2 Rokkor

I have both the summicron and rokkor. But somehow i prefer the 40/2 Rokkor. Maybe it's the lens cap of the summicron. Here's some pics by the Rokkor.
