Advertisement Posted January 30, 2017 Posted January 30, 2017 Hi Edax, Take a look here M10 rangefinder "considerably greater accuracy". I'm sure you'll find what you were looking for!
Tobers Posted January 30, 2017 Author Share #62 Posted January 30, 2017 That's a super picture. It's really closely packed in there. I've embedded the pic for others to see. Link to post Share on other sites More sharing options...
Guest Posted January 30, 2017 Share #63 Posted January 30, 2017 Forgive me if I digress slightly but it is connected. I wonder how to go with the coming M10 (on order). On my SL looking at the instruction manual of the Diopter for in the studio with reading glasses on I am on the third full mark i.e. 10thfrom the left. I think this is -1. According to the manual the bigger full-point marks would go from left to right, -3, -2, -1, 0, + 1. So with my Distance glasses on I am on the 6 th mark from the left. I presume that is -1.75. Now when I receive my M10, I am wondering which Diopter to buy. If I stuck to only one pair of glasses i.e. Distance: 1) The M10 Viewfinder is preset by default to -0.5 2) it would appear that either -1.0 or -1.5 Diopter would be the extra one I should buy. I have made an appointment next month with a eye specialist who said he can tell me for sure. Will only then know I guess. Leica M-Viewfinder is preset by default to -0.5 IMG_0144.JPG is the Reading glasses IMG_0112.JPG is the Distance Glasses Welcome, dear visitor!

jaapv Posted January 30, 2017 Share #64 Posted January 30, 2017 It may be a decent indication, but still, the best way is to visit your local Leica dealer and simply try which dioptre works best for you (assuming that he has stock) Link to post Share on other sites More sharing options...
Luke_Miller Posted January 30, 2017 Share #65 Posted January 30, 2017 Not sure the correction needed for an EVF has any relationship to that needed for a rangefinder. With the EVF you are looking at a magnified view of an LCD that is very close. Similar to looking at the focusing screen of an SLR/DSLR. With the rangefinder the viewing distance is longer. In my case the correction necessary for EVF or DSLR viewing is fairly close to the correction I need for reading, while the correction for my Ms is much less.

Interesting and thanks for the info. Seems I will also need to go back to the Leica Store and check these Diopters out again. Link to post Share on other sites More sharing options...

Cliff S Posted January 30, 2017 Share #68 Posted January 30, 2017 I needed a +0.5 to counteract the inherent -0.5 and with my glasses, I see things just a bit sharper. Link to post Share on other sites More sharing options...
steppenw0lf Posted January 30, 2017 Share #69 Posted January 30, 2017 As many have astigmatism and need correcting glasses for that, it is usually better to wear (corrected) glasses than using the cameras diopter control. The M246 works ok with glasses, the M10 should be even slightly better with the new viewfinder (though the difference is probably minimal). The SL is really perfect for people wearing glasses - better than any other camera I know. Link to post Share on other sites More sharing options...
pico Posted January 30, 2017 Share #70 Posted January 30, 2017 Pico, I'm not sure if this is what you mean (probably not) - but the "Barnack" screw-mount Leicas, and Canon copies, had a lever below the rewind knob (right) that - I believe - adjusted the viewfinder focus (diopter setting of the eyepiece). Yes, my mate's Leica has that lever but it does not help me, possibly because her finder is so dim from old age. Link to post Share on other sites More sharing options...
adan Posted January 30, 2017 Share #71 Posted January 30, 2017 It wouldn't surprise me if Leica eventually - or even rapidly, since the M10 eyepiece is larger than any previous M, so the current add-on diopters require an adapter (or in Chris Tribble's case, scotch tape) - creates a variable add-on diopter corrector. It would save having to build a whole additional set of larger single corrective lenses for the M10 eyepiece. Basically - a smaller version of the SL eyepiece, with the rotating ring to change the diopter power. Screws into the M10 eyepiece. Just how much smaller is the question. Diameter can probably be reduced quite a lot. The depth is somewhat dependent on having "empty space" inside for the glass elements to move around in, but the SL's glass seems deeply inset to form a natural eyecup (in addition to the thick rubber protective ring on the back), whereas in the M diopters, the back of the device is almost flush with the back of the glass. So we can probably shave off several mm right there. And make the rubber ring removable. And, yes, there would be an optional step-down ring, so it could be fitted to previous, smaller M eyepieces. Even an M4. Trivial. Below is just hypothesizing with some M10 and SL imagery in PS. A guess at retail, just based on the prices of the current diopters and magnifiers, would be around 500 $£€. If you aren't there yet, youngsters - believe me, as your eyes age, a variable eyepiece correction becomes more necessary. Your "correction" drifts over the day, from bleary wake-up eyes, to peak performance, to tired eyes after 4 hours shooting. Aging ain't for sissies. But it would still be optional.

digitalfx Posted January 30, 2017 Share #72 Posted January 30, 2017 I think this is going to move your eye way to far from the OF to be practical with a rangefinder. While the M10 eyepiece is larger, its a very small amount and not enough for something this large. Link to post Share on other sites More sharing options...
UliWer Posted January 30, 2017 Share #73 Posted January 30, 2017 Your idea is good! If a "shrinked" version of the SL-device would be the right solution, is not clear, since the projected picture from the SL EVF seems to appear closer than the 2m distance the M finder shows. Though in principle the idea might work. Edit @ digitalfx : If you look at the 1.4 magnifier already offered by Leica, the distance of additional lenses to the rangefinder might be solved.

adan Posted January 30, 2017 Share #74 Posted January 30, 2017 @digitalfx - if your theory about eye position is correct, then presumably these devices are not practical with a rangefinder either: http://thedreamwithinpictures.com/blog/focus-better-with-your-leica-m-rangefinder-with-this-adjustable-viewfinder-magnifier https://www.cameraquest.com/jpg6/LM1.25x2.jpg http://www.meteor.com.hk/shop/5026-large_default/leica-viewfinder-magnifier-m-125x.jpg One of the features of the new M10 finder that Leica trumpets is "longer eye relief" - i.e. the eye can be farther from the built-in eyepiece. You might be right...reality will tell us, sooner or later. Link to post Share on other sites More sharing options...

You might be right...reality will tell us, sooner or later. All I can tell you is that with glasses I can barley see the 35mm frame lines on the M10 and the 28mm frame lines are not visible. Push the eye another 3/4" + from the eyepiece might be too much. Now if they can cut your design in half maybe. Link to post Share on other sites More sharing options...
digitalfx Posted January 30, 2017 Share #76 Posted January 30, 2017 I posted this in another thread...but this may be a solution for those with astigmatism like me. I bought this for the M9, and although it worked I prefer to shoot with my glasses rather than constantly changing back and forth. http://walterrxeyepiece.com Ive sent him an email to see if he is still making these.

UliWer Posted January 30, 2017 Share #77 Posted January 30, 2017 Well, digitalfx is right as the magnifiers don't have to cope for the whole frame of the viewfinder. With an 1.4 enlargement the frames for 50mm are the very limit. Adan's idea of an adjustable diopter correction should not enlarge, and it makes most sense when you use it instead of glasses. Therefore many who are so much used to their glasses - or so dependant on them - will not use any diopter correction - since they wear it on their nose. My binoculars allow much more correction than any correction lenses we discuss here, but I leave it on 0, for I never use them without glasses (I might not find them without my glasss on).

Rick Posted January 30, 2017 Share #78 Posted January 30, 2017 That variable diopter Adan suggested would never fly... Most Leica forum members would complain it would catch on their bag. Link to post Share on other sites More sharing options...
russell Posted January 30, 2017 Share #79 Posted January 30, 2017 The diopters are not the solution for many, even if you try them on in person. Most of us have astigmatism and/or progressive lenses. Something like Walter might work, but I'd rather use my glasses. I bought a diopters that was closest to sight, but it was a waste as it's still nowhere near what I'd get with a prescription. Having said that, I went back to my M3 late last year and the viewfinder is magnificent -- but the metal eyepiece destroyed my glasses lens coating. Speaking of the M3, one reason it was so clear was the use of gold in the optical chain. I remember that discussion from a long time ago. Then they cheaped out with the M2 and later cameras. Could it be that the M10 clarity is due to the use of gold again? Link to post Share on other sites More sharing options...
