omllr Posted January 28, 2016 Share #1 Posted January 28, 2016 Advertisement (gone after registration) Hallo, I have an M6 TTL, and the viewfinder outer rubber ring is a bit old and wound out. I wear glasses, so i am afraid to scratch them. If i am right, the outer viewfinder lens on camera is -0,5. Why? If i purchase one +0.5 Diopter Correction Lens, it will be 0,0. If so, it will maybe be perfect. Does this diopter correction lens have a ring of rubber on outside? It looks like on pictures at the web. I have not seen any in a shop, nobody has it. Thanks for any input. Sorry for my bad english. Link to post Share on other sites More sharing options...

nobbylon Posted January 28, 2016 Share #2 Posted January 28, 2016 The viewfinders are all -0.5 internally. the eyepiece is clear glass. The correction lenses have a hard plastic coating on the outer ring. Link to post Share on other sites More sharing options...
omllr Posted January 28, 2016 Author Share #3 Posted January 28, 2016 Thanks "The correction lenses have a hard plastic coating on the outer ring." Will this "plastic coating" be too hard for glasses? I prefer to wear glasses when i shoot. Too inconvenient to take them on and off. Link to post Share on other sites More sharing options...
nobbylon Posted January 28, 2016 Share #4 Posted January 28, 2016 if you wear glasses then no need for correction lens. Link to post Share on other sites More sharing options...
spydrxx Posted January 28, 2016 Share #5 Posted January 28, 2016 It is not correct to say you don't need the diopter if you wear glasses. Obviously you intend to shoot wearing your glasses, but if your prescription doesn't provide for proper focus at the 1 meter mark, or you have an accommodative disorder which doesn't allow your eyeball to have the elasticity to make minor focusing accommodations, you may well benefit from a diopter. My eyeglasses are progressives but focusing at 1M is a really narrow band way down on the glasses which have been optimized fro driving, so a diopter works just great for me.

lucerne Posted January 28, 2016 Share #6 Posted January 28, 2016 I have been able to find a rubber "eyecup" that screws into the Leica viewfinder and it has a thread to accept a diopter lens without that lens protruding. It works very well and would avoid any possible damage to your glasses. It also helps by cutting out extraneous light reaching the viewfinder and I would miss it now. Unfortunately Leica changed the design of the Leica Q and the device cannot be fitted to my new camera. A Leica dealer should be able to source this accessory.

Closer to 2m virtual distance to focusing patch, but even that's an oversimplification. This FAQ addresses both this issue as well as the OP's question about the negative correction built in... http://www.l-camera-forum.com/topic/216580-leica-m8-m82-m9-m9p-mm-mtyp240-faqs-questions-with-answers/?p=2464130 The moral of the story is that, even considering all the technical details, eyes and preferences/comfort levels vary by person.....best to experiment than to theorize. A good optician will allow for testing with your camera. I'm fortunate that my eyeglass prescription (which also corrects for astigmatism) allows me to see both the RF patch as well as distant objects so that I don't have to keep putting on and taking off glasses. Plus, in daylight, I need sunglasses for light sensitivity, and a diopter of course wouldn't help that. Each person is different. Jeff Link to post Share on other sites More sharing options...
