visoflex and medium format lenses

[geotrupede]

All,

Does anybody know of an adapter for the visoflex that can shift medium format lenses?

I have seen a very interesting one for Canon SLR in action, but obviously nothing on the M system. What about attaching one to the Visoflex?

Is it technically possible, does it exist? Who can make one in Europe?

What are the issues?

Thanks

I have never seen such a thing and doubt one has ever been made (at least, as a standard commercial product) : in theory, there is "space" to do it... Viso II/II on M has a flange distance of 68,8mm... Hasselblad is 74,9 (and Pentax 67 even more) ; you could insert in the middle a well engineered adapter with shift facility and accomodate a Planar 80... even a Distagon 50 or 40... lenses that, if I remember correctly, do not have glass protruding over their back flange (which isn't true, I think, for some lenses for bellows-based MF systems like Mamiya 67) ; a challenging exercise to do for a good DIY mechanic... with some gymnick, one could add even a (limited) tilting capability, maybe (probably, in a range of +- 5° or so... no much more)

Lenses for 6x6 6x7 have a coverage sufficient to allow a decent shift, keeping the coverage of 24x36... computation is simple...and even more lenses for LF... but, given their construction, I doubt that, say, a Super Angulon 65 or 90 (or the huge Biogon 53 and 75 ) could be adapted.

I am thinking of a Pentax 645 35mm f/3.5 which does not have protruding elements.

I have seen one in action on a Canon SLR and results were really good.

Shift only, for architectural shorts.

The adapter was a custom made mounting with a rotating shoe and a shift setting.

The rotation allowed to select the shift direction.

The final image was constructed of a series of shifted shots, typically 2 or 3.

Quality of shots was very high, not vignetting or distortion, rather red edge for extreme shifts.

 

I wish I could find something for the camera I use.

At the moment all I can do is to use a 12mm and crop to simulate shift, but it is not ideal.

 

Since I have only a Leica I was wondering if a similar approach could be used with the Viso.

Question is then, is there anybody in Europe able to build such a thing?

PS What about this one: Shift Adapter For Use P-SIX Lenses On 35mm Cameras ??

Interesting... thanks for the link... even not costly, but of course too "long" for a Leica+Visoflex... I see it has a Leica R mount version... add a R to M adapter (which does mount to Viso II/III) and all is OK... :oapart focus, which will result in some odd near distances range - no infinity. Right solution for a Digital Leica M type 240 (which can also accomodate other shift solutions)

 

I haven't idea if there is someone in Europe with a lab taht can design and buid such an adapter... in Italy Adriano Lolli (COMA) builds a number of odd adapters... you could try to ask him via mail : Adriano Lolli - Home Page

You made my day with Adriano's site

Here's another one:

MIREX-Adapter

Though they may not like it (with regard to their existing inventory) but imo they're looking forward to start anew with the advent of the mirrorless FF; Sony being the first, probably followed soon by Canicon & Fuji.

So much more space for shifting and tilting (with a sturdy return to zero degrees, too), due to the absence of the mostly obsolete mirror-box.

 

Sorry, but DSLRs and their mirror-boxes remind me of the very first automobiles: they looked like horse-carriages, with the horses being replaced by a feeble engine. Later cars started looking like automobiles. And that's what camera engineers are looking forward to right now imo.

No wonder the vast majority of photographers...

("They don't deserve this noble title! They don't adjust wheels and buttons on their toys " )

...lost patience with the R&D of the "classical" camera giants and take their pictures with the multi-tasking device, called phone, in their shirt pocket.

Good for them all. I love film!

And I'm looking right now at what COMA has for my Canon 1V, that I don't have yet.
