Apert the obvious consideration (focal length IS different 😉) the difference can be appreciated in macro (or next to) usage : the last Elmar (black version) is really still a very good macro lens (very similar to Macro Elmar 100 R for bellows imho), with the collateral advantages of preset diaphragm and an "intrinsic" lens hood: I have both those lenses, and no doubt that for macro work Elmar is better.

The 3.5/65mm Elmar is perhaps the more versatile. (You may look at the Visoflex charts o see the differences: https://wiki.l-camera-forum.com/leica-wiki.en/index.php/Visoflex_III_1970s_Chart )

Though when you use the lens head of the 2.8/90mm Elmarit on the bellows II with the Visoflex you will hardly find anything better than this combination. The Apo-Macro Elmarit-R is of course much better fully opened, though f/2.8 is not very helpful for macros. When you stop down the Elmarit you won't see much difference when you compare it to the most renowned Macro lens ever made.  The 65mm Elmar shows more distortion and much less resolution in the range you can cover with the bellows..

For somebody interested in the (old) Visoflex sphere I'd always recommend to get a complete 1:2.8/90mm Elmarit. You may get it rather cheap on the second hand market. The lens head is excellent on the Visoflex and in my opinion the whole lens is the most underrated lens you can get for the M (in rare cases and more expensive even for screwmount).

direct comparison?

I can only find a MTF for second version in the books I have. The second version is a Midland redesign of original Wetzlar design, so reasonable to assume some improvements made.

I have the first (chrome) version and have no problem with its rendering (M10 / Visoflex II )

... yes, that's what the "Leica Pocket Book" says. Though if one looks at the lenses ... the early silver version is very obviously engraved with "Canada" and the later black version with "Wetzlar". I think Lager and Thiele have it right saying the later version was a Wetzlar design.

As far as I know indeed the silver chrome version is the first, Canadian version and the black version the later, redesigned Wetzlar version. I never notice any difference between these two either. I like this 65mm Elmar a lot, it works very easy on the Visoflex, and with the focusing unit only you already get rather close to your subject.

I haven't been using the lens head of the Elmarit 90mm very often, perhaps I should try more often.

My 65 Elmar setup on M10 - picked up my copy relatively cheap here in Australia - I think the Visoflex addition (complication?) for these lenses puts off many users so there isn't the demand from my experience. BTW is there a ring/spacer you can use to replace the visoflex unit - IIRC there was a Novoflex one or did Leica make a ring that was the equivalent to the space/gap made by the visoflex?

Yes, extension ring # 543195. Rare, but not impossible to find. There are lots of threads about this item.

Yes : LEM/VIS still available I think (i bought it when introduced, several years ago... I think in coincidence with M240 intro... the EVF capabilty mad very interesting such an accessory)

Good both for long focals and macro with bellows

Yes, Novoflex still offers the LEM-Vis-Adapter as a substitute for the Visoflex housing:

With their last version they listened to the (my?) criticism that the four separate rings often give a wrong position e.g. for the bellows. You can change the position of one of the rings to set it straight.

If one happens to have an R-to-M-Adapter one might remember that Leitz made adapters for Visoflex-lenses for the Leicaflex (14127) or R-cameras (14167). With one of these you also can substitute the Visoflex:

Though after all I still find the Visoflex III housing the most comfortable. You can fix the mirror in upper position so it won't bother your sight by Liveview and remove the release lever (which is reversible). The Visoflex III is not heavier than the LEM-VIS and much lighter than the combination of R-Adapter and 14127 or 14167. Both versions of ring adapters will show vignetting with long focal lengthes, which the Visoflex doesn't. The Viso also gives you an additional position for a tripod (the LEM-VIS doesn't) and you can easily change from landscape to portrait mode (which the R-to-M-adapter doesn't allow).

Uli, I have not experience with rings made for reflex Leicas... what is the function of the f/stop ring  on the 14127 ? Is it related to the TTL exposure  of R bodies ?

About your observation on vignetting... I have not experienced it, at least with the long lenses I use (Telyts for Viso II/III) ... maybe (but don't remember exactly) vignetting occured with my LEM/VIS with OUBIO attached and lenses like the 200 or 400 for Viso I....

This was only for the first Leicaflex to ensure the right exposure - it's obsolete now.

The vignetting of the 280mm Telyt with the Lem/VIS II may be seen here:

 

I think you use the LEM/VIS I, which is in one part and doesn't show the vignetting.

I have a LEM-VIS version made by Amedeo Muscelli but its bayonets are a bit on the tight side. I think Amedeo sometimes gets the figures a little bit wrong on his CNC programmes. The coding pits on my Contax to Leica M are in the wrong place. Pity because his stuff is beautifully machined.
