tonyniev Posted July 22, 2017 Share #1 Â Posted July 22, 2017 Advertisement (gone after registration) I just came form the camera store and had a good chat with the Leica sales/district manager visiting Las Vegas this weekend, I had a question relative to the Elmarit 28 and when he saw the lens he said you cannot use that it will damge the sensor, after I told him I have been using the lens since I got the M10, he corrected himself and said the Elmarit 21 is the one that cannot be used. Â I have a Hektor 135, it also has an extended back, do you know if I can use this in the M10? Â I have not tried it for fear it may hit the senor. Â Thanks.

Advertisement Posted July 22, 2017 Posted July 22, 2017 Hi tonyniev, Take a look here Hektor 135 mm for use in the M10. I'm sure you'll find what you were looking for!
luigi bertolotti Posted July 22, 2017 Share #2  Posted July 22, 2017 Extended back on a Hektor 135 ? Why ? No Leica long lens has anything prolonging over the lens'flange. Any 135, Elmar or Hektor or Elmarit, can be safely used on M10 and other digital Ms, though Leica (in consideration of tolerancing on such lenses) does reccomend not to use them wide open, but at least at f8, to assure correct focus (which is a "conservative statement" indeed we have seen many examples of perfect focusing even at wide apertures)  Welcome, dear visitor!

jaapv Posted July 23, 2017 Share #4  Posted July 23, 2017 I think you should be looking for another camera shop. It is utterly impossible for any lens that does not hit the film on an analog M to hit the sensor on a digital one; the register distance is obviously identical. The only critical lens on a digital M is the old collapsible 90; it might just touch the baffle in front of the shutter when collapsed, but even that scenario is unlikely.

Isn't the cover glass in front of the sensor? If so the distance between flange lens mount and the shutter might be a fraction shorter.

Exodies Posted July 23, 2017 Share #7 Â Posted July 23, 2017 Advertisement (gone after registration) Of course, it's not the distance to the sensor that is the problem but the distance to the shutter. Link to post Share on other sites More sharing options...
jaapv Posted July 23, 2017 Share #8 Â Posted July 23, 2017 Even then, there is no lens that was built so long that it will hit any shutter. The metal shutter of the digital Ms runs a bit closer to the sensor than the cloth shutter of the film Ms does to the film as far as I am aware. The problem that may ensue is the width of the rear of the lens and the distance to the light baffles in front of the sensor - and the only lens that comes dangerously close is the Elmar 90 collapsed (old type). The other lens that may pose a problem is the DR Summicron, as unmodified ones have a large flange, but it is said that they are no problem on the M10 (unconfirmed).

UliWer Posted July 23, 2017 Share #9 Â Posted July 23, 2017 Certainly there is no problem at all that anything from a 135mm Hektor, or any other 135mm lens which fits a Leica could hit the shutter. Â The lens-to-shutter-issue might be raised for retractable lenses - tons of discussions about this in the forum. There are no 135mm retractable Leica lenses. Â Not even the the old retractable 90mm Elmar will touch the shutter. Its rear end is just to broad to enter the "mouth" of a digital M, it will hit the sides of this mouth before it gets near the shutter. Â P.S: Looking again at the title of this thread I have to correct myself: The "Lektor" - also called "Hannibal" during its production times - will not only hit the sensor but eat it - alltogether with the filter glass - and will have the shutter for dessert.
