I wanted to demonstrate the resolution of a 1973 Leitz Tele-Elmar 135mm F4 Lens on a 2010 Leica M9. The first full frame image is a chimney with a TV aerial on my neighbours roof some 50 metres from where I was standing
The second image is a crop of the first.

Thanks for your comments. Yes ! That's the one ! Looks like you raided Ken Rockwell's web-site for the image ? My lens is well used and show signs of wear (bought second-hand) mainly because the aperture stops are worn and not as tight as is normal with Leica/Leitz lenses. But it performs well anyway. Only problems with the design of the lens are the minimum focussing distance is 5 feet and the depth of focus is very shallow at f4 which means that it is usually advisable to set apertures between f5.6-f16 which does restrict handheld shooting in poor light.
Regards.
Ray.

Leica lenses go on and on, but a slightly loose aperture ring on an old lens isn't unusual. My Elmarit 90 is the same vintage and also a little loose. Of course some of these lenses have had 20 years use day in day out with a working pro tog.
Interesting idea for an ongoing thread, old glass on digital bodies.
Light thinks it travels faster than anything but it is wrong. No matter how fast light travels, it finds the darkness has always got there first, and is waiting for it. Terry Pratchett.
Hi Ray,
I have that lens and mine was made in 1969. Yes, indeed, it is a sharpy.

Bob,
Do you still use your '69 lens on your digital Leica ? I think it is an amazing lens and compares favourably with the telephoto lenses made to day. I still find it quite extraordinary that the bulk of the Leitz/Leica lenses made since 1954 are still able to be used (without adapters) on modern Leica M mount cameras.

Hi Ray,
Yes, I keep it in the bag. It is eqv 180mm on my M8. It is a bit awkward without any framelines.
I think there are only a few Leica M mount lenses that wont work on the M-digitals. With the internet it is fun to find out about non-Leica M mount lenses that I never knew about, too.

And of course the Leica Thread Mount which goes back to the earliest days only requires the simplest of adapters to work on M mount. This brings in a huge range of Leica, Canon, Russian and other lenses, including some good english ones.
I sometimes use my 1933 5cm f2 Leica Summar on the M - gives a nice soft focus but very prone to flare and low contrast.

Bob,
I hadn't appreciated that the M8 would have a problem with the "frame lines" until I read your message - the M9 sensor being the full 35mm like the film M's does have a frame for the 135mm which is accurate - well as accurate as any of the frames are for the different lenses - but fortunately they always err on ensuring that a slightly larger field of view is captured than that seen in the frame.

Ray,
It is a bit of a game to get the framing using the focusing patch. Some 135s can be modified to bring up the 90mm frames which are more useful that the focusing patch, but our tele-elmarit can't be changed.
On the M8, the 90mm has a 120mm eqv field, so it covers for the 135mm. This makes the 135mm a specialty lens. My 90mm preAsph Cron gets a lot of use, even though it is my biggest/heaviest M lens.
