Hi Gerry,

Regards from Vancouver! I am sure you do not miss Montreal - over 2 meters of snow accumulation this winter……..

As to the goggled 3.5/35mm Summaron, even though that was my first 35mm lens on my first M3, I don’t recall how the cam worked with the goggles removed. The M2 was introduced after the discontinuance of the 3.5 Summaron so, I don’t think the goggle’s removeability (is that a word?) was there to allow the lens’ use on the M2. It was probably made that way just for ease of manufacture, even though in those years Leica did not care much about that…….

There also was a 3.5/35mm M mount Summaron without the eyes - it, like the goggled lens, keyed in the 50mm frame and was meant to be used on the M3 with an external shoe-mounted finder. That lens could be used on the M2 without any problems if one filed the frame actuating bayonet lug down - that would prevent any frames from being keyed in and the default frame on the M2 was 35mm. I am in the office and do not have access to my Leica ‘bibles’, so can’t tell how close the 3.5 Summaron focused with the goggles - the non-goggled one focused to 1meter.

Maybe Luigi will have a better answer?

All the best,

Jan
