what lica lenses can be made to work with a K5

hi

well i was surfing the flickriver and was blown away by the lica lenses specially the Leica Noctilux 50mm f1.0.
so im wondering is there any lica lenses that can be made to work with a pentax k5 and will they produce similar results.


thanks

Dear nirVaan: The problem is backfocus = the distance from the back of the lens to the image plane. For Pentax and all other (D)SLR cameras the backfocus is long because of the mirror. For Leitz lenses designed for the "M" series range finder bodies, the backfocus is much shorter. Therefore, andy/all Leitz range finder lenses can NOT be focussed to infinity when mounted on any (D)SLR, even if you could locate an adapter. They can only be used as close-up lenses. The only Leitz lenses than can focus to infinity when mounted on a (D)SLR are some of the telephotos that were made to be used with a Visoflex housing (=Leica's method for converting a rangefinder camera into an SLR). Old screw-mount Leitz telephotos are the easiest to mount on a (D)SLR (easier to locate a Leitz screw-mount adapter than a Leitz M bayonet adapter).
NOT possible to mount the Noctilux on a K5 and be able to focus to infinity. It could only be used for fairly extreme close up, probably less than a meter, and it would not be a good lens for such use. Modern, far less expensive macro lenses would out-perform it easily.

and if you really want a leica lens... there's R mount too and all the f1.4 summiluxs

Morning,

Here is a website with some information. They supply specific mounting kits for a number of quality older lenses from Leica (R) and Contax (Carl Zeiss) along with Olympus (Zuiko).I have two older Contax (Zeiss) lenses that I have (or rather had) remounted with their K mounts, and they work perfectly well. Their mounting kits, for specific lenses, take in to account the difference in the registration distance (the distance between the sensor and the physical lens mounting flange on the body).

The other observation is that there are other factors involved like - availability, location, opportunity and most important of all, the skill of the photographer, and how they see the world around them..... actual equipment comes in pretty low on the list.

Hope that helps......

i agree but the sharpness and the out of focus rendering Leica Noctilux 50mm f1.0. is something that i haven't seen in other lenses

Morning - Have you looked at the current pricing for the lens?Then there is the "Special Edition" of the lens.... - note, that this version comes with its own set of white gloves....... they certainly are special lenses.

All Leica lenses are easy to use -- just not on Pentax PK-mount cameras (except Leica R-mount). Try Olympus m4/3, Sony NEX, Samsung NX, Pentax Q, etc. These shorter-register cameras can all take short-register Leica rangefinder lenses.

Respecting expensive Leitz equipment. Quite a way back Leica made, for a very short time, an 800mm lens - NOT the later modular 280-400-560-800 kit. As I remember, you had to order one and wait - no camera store carried it in stock. The standard joke was that instead of a pouch or case, it came with a padded Volkswagen for transport.

Sorry gekino, I don't know about the Vario Elmar.

But wasn't the punchline of the joke that the Volkswagen cost less?

If you can swing the price of the noctilux you can afford the M9 to use it on IMO
It's a pretty fantastic lens. If you manage to steal one and want a low cost alternative get the GXR M mountor which performs better with the leica lenses than the Nex cameras

I would note one caution from Leitax

QuoteQuote:
CAUTION! The Leica Zoom lenses with ROM contacts are, in general, not suitable for Pentax conversion. Most of models would need a custom and expensive work. I would recommend to find a non ROM model in case you wish a Leica Zoom lens.

I would also say the real value in the R to k conversion comes in some of the fantastic primes in R mount that are now stupidly cheap compared to what they sold for originally since Leica has abandoned the Mount.

the really sweet one to try for is the Summicron 90
