Correction lens for M8

[rboaden]

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?

Leica advises contacting an optician who will be able to make you the correct lens. They supply the needed ring.

Thanks for that info.

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

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.

He has charged me about $150-180 2 or 3 years ago.

First you need to get a blank for the diopter from Leica - if in the U.S., call Deve Elwell at 800-222 0118.

If you get in touch with him, I'd appreciate your letting me know up to date contact info.

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.

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.

Thanks for Dave's info -

Sorry for my bad grammar - what I meant was an update for Jason's contact info.

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!).
