Correction eyepiece for Zenit 3M

Hello all,

I have a Zenit 3M in very good condition but unfortunately I less and less use it as focussing is getting difficult with the plain frosted glass... Being now far-sighted, I could use it with me glasses but being the only user of this camera, I would rather prefer to adapt a correction eyepiece and get rid of my glasses...[8D]

Do you if it does exist or if it is possible to adapt eyepieces from other brands[?]

Thanks for your contributions!

Hi gelios,
just unscrew the black rear ring on you finder and place a correction lens (+ 1 or +2 ?) from your optician shop, under this ring, and then screw it again (the correction glass will be tight between ring and prism ).
An optician can easily fit (cut arround) a lens diameter to your 3M finder.
