rboaden Posted January 10, 2007 Share #1 Â Posted January 10, 2007 Advertisement (gone after registration) In order to use a correction lens I need a -6 diopter lens. Leica offers correction lenses up to only +/- 3 diopters, Does anyone with more knowledge of optics than I possess know if you can put two -3 lenses together to achieve the result of a -6 correction?

jaapv Posted January 11, 2007 Share #2 Â Posted January 11, 2007 Leica advises contacting an optician who will be able to make you the correct lens. They supply the needed ring. Link to post Share on other sites More sharing options...

jedisdl Posted January 11, 2007 Share #4 Â Posted January 11, 2007 Custom correction lenses are made by Jason Klimak, tel: 810 600 5203 (in U.S.) - possible address is: 5203 Merit Drive; Flint MI 48506 I think his cell is 810 691 6952 Â He moved a couple of years ago, so I'm not sure of the above info, but at least one of these phone numbers should work. Â He has charged me about $150-180 2 or 3 years ago. Â First you need to get a blank for the diopter from Leica - if in the U.S., call Deve Elwell at 800-222 0118. Â If you get in touch with him, I'd appreciate your letting me know up to date contact info. Â Steve Link to post Share on other sites More sharing options...

carstenw Posted January 11, 2007 Share #6 Â Posted January 11, 2007 You cannot stack them. The camera's viewfinder is threaded, and rubberised. So is the magnifier. The diopter is not threaded, and is made of hard plastic, I think, so if you sometimes wear glasses and sometimes use a diopter, and press your glasses against the camera and hear a little *click* from the plastic, then you know there is a diopter in there and you should take your glasses off. Very clever. Link to post Share on other sites More sharing options...
cbretteville Posted January 11, 2007 Share #7 Â Posted January 11, 2007 Advertisement (gone after registration) Leica sells the correction lens mount separatly for people with asigmatism, no reason why an optichian can't place a straight +/- whatever in that mount. Don't have the part number though. Â - Carl Link to post Share on other sites More sharing options...
jedisdl Posted January 11, 2007 Share #8 Â Posted January 11, 2007 Thanks for Dave's info - Â Sorry for my bad grammar - what I meant was an update for Jason's contact info. Â Also you should be aware that although he is very reliable (he has made 3 custom diopters for me at different times) - he can be very slow (months sometimes!).
