Rokkor 40mm on Leica M?

Just read this on photo.net:

“The Rokkor 40mm designed for the CL can be adapted to the M so that the 35mm framelines will quite accurately show the area covered by the 40.”

True?

If so, how?

 

 

And can someone link to a good example of this lens? I need an idea of a fair price, and I don't know how fast it is..

I need to buy a 35, 40 or 50mm lens for my M7 and it could be a 35 / 40 / 50..but the idea of getting accurate frame lines appeal to me, as does having a lens whose image nearly fills the viewfinder.

thanks so much

very easily but it does involve getting a file out and modifying your mount-obviously non reversible! There was a thread on how to do it including photos. If I can find a link I'll post it!

Oh and a good example of the leica Summicron version of the same lens costs about £200 in good order.

And both the 40mm summicron and the 40 Rokkor will fit on my M7? Adapter needed for either?

 

One lens better than the other?

Yes, both "compatible" with your M7, no sort of adapter needed... but if you haven't yet a 35 or 50, I think that it is probably better to think to one of them... M7 framelines are rather precise and with 35 or 50 you have the PROPER frame: the Summicron40 f2 has the advantage of a cost that, in comparision with a Summicron 35, is generally lower at equal conditions: disadvantage is that it has a "strange" filter size and a rubber hood that is easy to find in less than good conditions.

Regarding IQ... Summicrons are always good or excellent lenses depending on versions/age. I think the Rokkor 40 is practically equal to the Summicron.

thank you..

 

I think I want a 40..there is a cron fs with a hood and filter in VG shape for about 425 US..seem right?

 

and if this were filed it would bring up the 35 lines?

And do you have any thoughts on the Voigtlander Nokton 40mm f/1.4 M-Mount in relation to the other 2 lenses?

I have both the Summicron & Rokkor versions. Each have their strengths, but it would take someone really knowledgeable to tell the difference, as long as the image is well exposed & sharp. I don't have a M7, but I believe it has a frameline for the 35. I use both 40's in the subway with my CL & M2. If you use the full finder, not the lines of 35, you will be dead on. I recommend this lens. It is a joy to focus, very small and it's resolution is superb. Here's a sample, from the NYC subway with crappy light. BTW, many longtime CL users claim that the Rokkor, with it's newer coatings is superior. Either lens will render very fine images.

I had the Nokton. It brings up the 50mm framelines. I used it happily on my M7. It was great for street shooting because you got a bit more on the film than the framelines showed. I wouldn't file out to 35mm. Very nice, compact, sharp lens.

Filing the mount just a little will bring up the 35mm framelines on any Leica camera that has 35mm framelines. But on a film camera the framelines will show way more then the lens will capture except at close to infinity focusing and even then the 35mm frame lines will still be bigger then what is captured.

On the original M8 the 35mm framelines are smaller then what a 35mm lens captures and using the 40mm filed to bring up the 35mm frames work very well. The framelines are a little bigger at close focusing and just about right at about 15 feet to infinity.
