My Dual Range Summicron will not work in the close focus range on my M6 - will it work on a M4?

Do you have the eyepiece "goggles" attachment that must be mounted on the lens to allow it to turn through the close focus range? Without it you can pull the focus ring out a bit and move it over the stop into the close range, but can't rotate the focus further until you mount the goggles. Mine works fine on M6 & M4.

While on the subject of goggles I understand there are two versions of the DR - early and late with their respective googles, and the goggles are not interchangeable between versions?

There is apparently a "large ball" version and a "small ball" version.  I don't know which is early and which is later.   I have two DR Summicrons, but they are both the same type so I don't know which they actually are.

I have both versions of the googles, the lens is the large ball type and I think this is the earlier version, in the pictures always the piece on top

Hello Everybody,

The earlier version of the Dual Range Summicron takes the finder with the condenser lens engraved on the front & also is engraved "E. Leitz Wetzlar" in the engraved condenser lens.

The focusing ring has knurled peaks & smooth valleys.

The second version of the Dual Range Summicron takes the finder that is engraved "Leitz Wetzlar".

The focusing ring has knurled valleys & smooth peaks.

Best Regards,

Michael

Used DR Summicrons are often sold without goggles, so how to identify whether the lens is early or late version?

Good question.

Look at the lens barrel.

Early - meters [black] distance only.

Late - dual distance scale *feet [red] and meters [black].

*edit distance scale color and scale

I believe it’ll work on the m6 classic and everything before that. It won’t work properly on an m6 TTL. I recently purchased a non DR rigid and it is my new favorite lens. Most of them have damage to lens coating like mine does but it doesn’t seem to affect the pictures.

Wonderful lens!

I keep mine on one of my M4s, with the goggles tucked in the bag. The other M4 usually has the collapsible 90.
