Advertisement Posted August 6, 2011 Posted August 6, 2011 Hi maccaco, Take a look here 135mm Lens on M8?. I'm sure you'll find what you were looking for!
lct Posted August 6, 2011 Share #102 Posted August 6, 2011 The only coding available for 135mm lenses is that of the Elmarit-M 135/2.8 AFAIK. See Leica 6-bit Coding and Leica M Lens Codes. Link to post Share on other sites More sharing options...
menos I M6 Posted August 7, 2011 Share #103 Posted August 7, 2011 I only code my long LTM lenses for ease of finding shots in the catalogue, made with a particular lens. This could be easily saved as well, as these long shots are easily spotted between the 35, 50 and 90mm shots. I use LTM adapters for 135mm on my 135mm lenses, not 90mm. I use the lenses on both the M8.2 and M9. I have learned, that bringing up the 90mm frame with 135mm lenses on the M8 is of no use. I shoot the 135mm lenses simply without frame on the M8.2 - easy enough. Adding a magnifier, when shooting 135mm on the M8 helps a lot with composition (it does not really help with focussing, as magnifiers introduce their own issues, focussing reliably. I am more into very fast medium telephoto lenses now in the 80 − 100 mm range. Canon 85/1.8 and Canon 100/2 LTM These very fast RF tele lenses give you more subject separation than the APO-Telyt wide open, but they won't do pancake faces, when used for portraiture, like 135mm do. The rare Canon 85/1.8 in fact gives a very similar dof like the huuuuge 135 Elmarit and gives better Low light usage, being more than a stop faster. These fast short tele lenses are more difficult to focus though, than say a Noctilux wide open.

wlaidlaw Posted August 7, 2011 Share #104 Posted August 7, 2011 A question ... Which encodes a 135/3,5-LTM Canon lens on the M8? As LCT says, the only code is the 135/2.8 but to make the code pick up, the frame lever has to be in the 90/28mm position, so you have to have a 90/28 LTM to LM adapter fitted on your Canon LTM lens, not the 35/135 you might think. The only benefit of coding on the M8 with a lens as long as this is to show up "135mm" on your EXIF's. There is no requirement for vignetting or UV/IR filter correction.

zombii Posted August 8, 2011 Share #105 Posted August 8, 2011 The 135/2.8 with goggles is a brute of a lens. It's made of the same materials as my normal chrome Leica lenses, but at that size, the weight is stunning (and not in a good way). As a result I don't carry it much. But the quality is very good and it's easy to focus and when mounted to something like an M camera it balances well. And it's cheap cheap cheap for Leica. So it's a cost effective solution, if heavy. I should also say that I also have an old Contax (Kyocera) body with a 135mm lens made by Kyocera with Zeiss optics. THAT lens is about the same weight and size. So it's not REALLY that the lens is ridiculously heavy, it's really that it's SO much heavier and bigger than the typical Leica M lens. It is a hefty lens. However, I also agree that the weight isn't that terrible. My problem with it is the cumbersome goggles. I have a grip on my M8 and I have to remove it to get the Elmarit 135 on and off. On top of that, it takes up too much space in the bag. I would like to take the goggles off. I think I can focus it without them. Has anybody else ever done this or had it done?

I would like to take the goggles off. I think I can focus it without them. Has anybody else ever done this or had it done? That was my major issue with the sample of the refrigerator as well, when I had it. The major issue for me indeed were the goggles. Comparing the 135 Elmarit with say a Noctilux, the Canon 100/2 or even the much faster focussing APO-Telyt, I would go out on a limb and would say, one could handle this lens wide open, when matched precisely to a certain camera body. The last part is the most important one. It will certainly not work on any body, which leaves the factory with standard tolerances. The lens has to be collimated, it's focal length verified (most certainly correct, given the meticulous optical work @ Leica), it's RF coupling has to be checked for any possible inconsistencies and finally, the camera body has to be checked for precise RF coupling from close focus to infinity. I have been going through all of this with the great help and input of a certain RFF user over the last weekend with the Canon 85 1.8 LTM lens, which was out of the factory in 1960/61 not spot on adjusted to Today's Leica M9 tolerance (who could blame Canon ;-) ). It is possible, to shoot such thin dof lenses with the M. One has to know the limits though and must make sure, all mechanics are up to spec. Now, that I think about it, this could be actually one of my future interesting projects - a goggle less, converted 135 Elmarit-M … mmmmmh. Link to post Share on other sites More sharing options...
FMB Posted August 8, 2011 Share #108 Posted August 8, 2011 I´ve my 4th M9 camera profile dedicated to "Apo 135" with the manual detection lens to "135 f/3.4 APO 11889" position and Auto ISO 1/125 - 400. This way always reflects the visible words "Apo 135" in the Info screen and the exact lens in the metadata figures. Of course one must adquire the habit of changing your camera profile every time you put and take out your lens. It´s only a problem of training a little, because this lens is not a common lens in the camera. Francisco. Link to post Share on other sites More sharing options...
JeTexas Posted August 8, 2011 Share #109 Posted August 8, 2011 I picked up an Elmarit 135 f2.8 this week. Framing and focusing is so much easier with the goggles, but as mentioned, it weighs a ton. I think the extra speed it gives over the Hektor is lost to camera shake because of the weight. Link to post Share on other sites More sharing options...
lct Posted August 8, 2011 Share #110 Posted August 8, 2011 More weight less shake. Same with 180 on FF cameras. Link to post Share on other sites More sharing options...
maccaco Posted August 8, 2011 Share #111 Posted August 8, 2011 Deception! Now I got the Canon 135/3.5 L39 mark II (black) but the M8 has big problems of focus. Anyone have this problem with this lens? I may solve this problem?... Any help is appreciated Link to post Share on other sites More sharing options...

Honestly, the lens is great and I would not waste which it ... That magnifier would be adequate? Link to post Share on other sites More sharing options...
lct Posted August 8, 2011 Share #114 Posted August 8, 2011 Depends if the lens is accurate at f/5.6 and on. If so, a magnifier would help you at wider apertures cartainly. Link to post Share on other sites More sharing options...
maccaco Posted August 8, 2011 Share #115 Posted August 8, 2011 I'm new to the world of telemetry (about 6 month, it shows, right? ) and I'm accustomed to good focus of the lens Voigtlander-M and Leica, and I never tried LTM lenses on the M8 except a Orion-15 28 that focused well. The issue is that I focused a box of cookies over 2 meters and the focus fell on the 2.20 mm f3, 5 .. And infinity is not going well ... What proof I can do to test the focus?... I will have the same problems with a Hektor 135 / 4,5 M? I hope to be understood Link to post Share on other sites More sharing options...
lct Posted August 8, 2011 Share #116 Posted August 8, 2011 Forget f/3.5, the M8's RF is not accurate enough w/o magnifier. Just check it at f/5.6 for now. Is it accurate there? Link to post Share on other sites More sharing options...

Wow, that's a big claim ! Don't mean, to disrespect LCT, but I (and others) certainly disagree on this. Proof of being: "Le Mans 24h 2010" M8.2 | 135/3.4 APO-Telyt wide open with ND filter on flickr … another during Sunday morning with a more demanding lens/ aperture on the M8.2: "Le Mans 24h 2010 Sunday morning" M8.2 | 90/2 pre ASPH wide open on flickr More can be found here and here. During the 2011 race @ Le Mans, I had to shoot the APO-Telyt mostly stopped down during daylight, as I forgot, to pack the 49mm ND filter The point is: the M8/ M9 rangefinder is perfectly capable of reliably shooting fast, long lenses wide open. Magnifiers do not necessarily improve focussing (more on that later). Especially do they not help at all, when a certain lens is not properly collimated to the Leica M standard, it's optical cell out of spec, it's RF coupling erroneous, it's LTM-M adapter out of spec, the bodies RF out of alignment, the users eyesight out of spec or simply a lack of experience with the particular lens/ camera combination and it's weak spots and demands. This is not a rant or an offense, but I see this argument written in big letters on the internet a lot, more so, since many new users of the M system are not fully educated yet about the technical boundaries of the M and it's demands on mechanical precision on all involved components (+ the probably most important factor: "Mensch" with the fully manual camera system). I will post some helpful advice after getting a few hours of sleep Tomorrow. Just a few days ago, I received my third Canon LTM lens in a row (and my 5th non Leica LTM lens in a row at that), which was not set up properly for the Leica M system out of the manufacturers factory, but misfocussed badly on calibrated M bodies. Mind you, the Canon 85 1.8 LTM lens, I am referring to, is not some cheap russian mass produced copy, but one of the pinnacle offerings of the then Canon RF system, similar in optical and mechanical advances as the Leitz 75 Summilux, when it has been introduced a few years later (more on that particular lens on my flickr stream these days). I will provide some detail later. Prepare a well maintained vernier caliper, a tripod, cable release, a close focus target, a suitable infinity target with good atmospheric condition, several LTM-M adapters of different makes, a computer with card reader and some patience and you will be rewarded with a wonderful Canon 135/3.5 LTM lens.
