Komura 2x Teleconverter and the M8 ?

Is it possible to use the 2x Teleconverter with the M8; and if so, has anyone figured out the correct codes.

 

I use my 2x normally with the 90mm f2.8 tele-elmarit lens on my M4 (though I have used it with the 35mm f2 and 50mm Summicron lenses for portrait work)

 

On a side note, I have read that it is possible to use my 135mm f2.8 Elmarit with the M8, anyone try to use it with the 2x Telecoverter on the M8 ?

 

Thoughts and comments would be appreciated.

I have the Komura and it does work on the M8. At least it works as well as it does on a film camera, which is to say, not very impressively. I've had several and none of them coupled accurately with the rangefinder. The one I have currently had the coupling disabled, how I got it for $25 which is what I think they're worth. I also find I need to stop any lens down to about f/8 (equating to f/16 effectively) to get decent performance, which is limiting. I used it tripod-mounted, with the lens either set at infinity or pre-focused via rangefinder with the lens mounted to the camera, and then put the 2X in place. It really works best IMHO on a visoflex, where rangefinder coupling is not an issue.

 

That said (probably more info than you wanted to hear), to address your question: Any focal length longer than 35mm doesn't suffer from IR-filter-induced cyan corners, so unless you're planning on using the 2X with an 18mm or shorter lens, I wouldn't bother with any coding. You'd have to use differently-coded LTM-M adapters on the rear of the 2X for each lens, which would be a royal pain only to get EXIF data in the file.

 

Another issue of course is framing. You'll need to factor in the M8's crop factor as well as the 2X. A 50mm lens would become a 135, the 90 becomes a 240, and a 135 would be a 360. I don't have the Komura finder so I'm not sure how far it goes (probably 270). Of course with the M8 you can always chimp the LCD if your subject is static.

Even an 18, assuming you would want to use that combo would be OK without coding, as the whole thing would be more telecentric than a regular 35 lens.

I guess I am very lucky. I got a converter when they first came out, and it has worked perfectly both in coupling to the rangefinder and in image quality. I have heard that some of the converters produced after the initial 1000 or so, have had a lot of problems.

I have a few extra adapters for the screw end, purchased for use of my screw mount lenses to the M4, of the converter to the M mount so I could create different coded mounts for what ever lens I would mate to the camera. But a 90mm as 240 would more than suffice for any work I would require.

 

BTW... I had almost forgot about the ability to use my Visoflex. I am sure it was just another senior moment <LOL>

 

 

Thank you very much for your information. It has been greatly appreciated.
