Is there any known problems mounting the old Summicron 50mm DR on the M6 classic .72 ?

I appreciate any experiences you folks can relay.

Cheers
 
You can mount the DR fine, but not with the goggle.
If the M6 different than the M7? Is there some reason the goggles won't work on an M6?

My DR and googles work fine with my M7. If you focus on a pin point of light you will notice that the focus patch doesn't quite match up vertically, it's off just a hair. Probably due to the slightly higher top deck of the M7 compared to the pre-M6 cameras. However, it is barely noticeable and does not interfere with focusing.

Is there something I'm missing?
 
From what I understand, you need to try the goggled lens with your M6 as it would seem that some work fine whilst others don't. I'm afraid the precise reason escapes me at the moment. It's something unique to the M6 as well I think. Hopefully someone who knows, or can at least remember will chime in soon.

If you're not interested in the close-focus ability afforded by the goggles though, I believe that the lens on it own should mount and focus just fine.
 
My former DR Summicron (with and without eyes) could NOT be mounted on my former M6 (classic) due to the shape of the light baffle near the meter sensor.
 
Thank you for all the responses. Just like the google I did there are conflicting experiences. I'm just going to bring them both here and see what happens. The DR is a lens I have wanted to try for some time. The M6 would likely not see another lens while with me so I really hope it works out. I use Bessas and a ZI so no go in any way for the eyes on those or my RD1. Sure I know a 90mm is more effective to get close but, I just want to try it 😀
 
Folks throw bricks at the M5 in favor of the M6. The D.R. Summicron and goggles work perfectly on the M5. Sell your M6. Buy an M5. Use the change to make photographs.

That's strange. Since the lens itself sticks no further into the body then the newest Summcron (I have both lenses in front of me). However the inner lens barrel does extend maybe an 1/8" past the end of the barrel when set to the closest focusing position. On the M7 there is an inner flange/light baffle that protects prevents contact with the meter, that flange has a larger diameter than the inner lens barrel of the DR. Are the classic M6's different? I can't take a picture with a digital camera but it would be interesting to see some photos of camera / lens box to see the difference.

I used to have a classic M6 and I know I used this lens on it. However, I never use the close focusing feature much so I may never have tried the goggles on the M6. If you don't engage the close focusing (by enabling the lock) you should be a least able to use it as a normal Summicron.
 
To make my former statement more clear, the lens could be physically mounted but NOT focused over the whole range (without the googles mounted). Mine was a 0.72x classic and it was similar as described on the cameraquest.com site:

[cited from cameraquest.com] "While he could mount the lens, if it was not focused at it's closest regular focusing distance, the close up range was inoperative due to some sort of internal body restrictions. Whether this is true of all late M6's in general, or of just the .85 model is not clear at this time. In any case, it's a good idea to try it out to be sure on your own body/lens combination."
 
I don't think the DR is as sharp as a good cleaned collapsible Cron.

If you need to get close, the CV ltm 15 goes to .3 meters, and without goggles.
 
Why and when it doesn't work

Why and when it doesn't work

Given Gabor's experience, I checked out why mine works. Attached a photo from the back with the lens close to infinity. The RF cam comes very close to the light meter baffle, but just passes by. I guess on a different camera, with different tolerances, it might hit the baffle.

But: this only happens close to infinity focus, in the close focus range the cam is far away from the meter. So if your DR works on your M6 without eyes, it will work with the eyes, too.

If you are on the fence, consider buying a rigid Summicron. Same glass, shorter cam, and if you want to get closer than 1m, maybe use a 90mm lens ? A 90 at 1m has about the same frame coverage as the DR Summicron at closest focus (with eyes).

This is strange i have a M6 classic and just got a DR with eyes last week (still waiting on the test roll). No issues at all. Works perfectly. I thought the issue with the DR was limited to the M6 TTL and above?

Not strange. You are lucky, just like me. Put it at infinity, open the back, put the camera on B and look how close DR RF cam comes to the meter's light baffle. In your and my M6 it doesn't touch, in others, like Gabor's, it does.
