Diopter correction lens -2.0 for M-mount Leica This is a diopter correction lens of '-2.0', which is rarely available used. I used it on my M6. Therefore, I have confirmed that it can be attached to the M6. I believe it can also be attached to other M-mount Leicas such as the M4, but please purchase at your own risk. I purchased this used, and it is a genuine Leica product, but I am not sure of its authenticity. The font of the numbers looks like a genuine product, but please also take responsibility for this. There are no noticeable scratches on the glass, and the visibility is good. The screw fits perfectly into the eyepiece of the M6. There are no particular problems with its use, but it is old, so there are some scratches. Please refrain from purchasing if you are sensitive to this. When shipping, I will put it in a small case and protect it securely. If you are looking for a diopter correction lens, please consider this opportunity. LEICA M2 M3 M4 M5 M6
