    Heya!

    I recently got my D7100 and I love it.
    Combined with my 50mm lens it does the trick to say the least.

    However, I feel like I lack variation, more lenses would be great.
    My grandfather was also into photography, before he passed away he gave me his old camera; A 'Chinon CM-3' to be precise, and three lenses of the same brand. All in mint condition, except the house that has been through alot since he bought it back in -79.

    The lenses are:
    • 55mm
    • 135mm
    • 28mm

    I would LOVE to be able to use these. I am however lacking knowledge about lens converters or if there even exist converters for such old models translated to my new D7100, or well, more recent at least.
    Am I pushing my luck believing I can use these lenses on the D7100?
    Do you need any other specs other then the old camera and the new to figure this out?

    Any help is greatly appreciated.
    Thanks!

    Being a Pentax K-mount type system, you'd be better off forgoing the expense of adapters and buying E-series lenses.

    What are the drawbacks of the adapters?

    1. They'll contain glass, which is necessary to maintain infinity focus.
    2. That glass will degrade image quality.
    3. It will cost more.

    '
    Would I be able to use the E-series lenses to their full extent?

    What you want is AI or automatic indexing lenses. There can be problems with some pre-AI lenses so, to be safe, avoid those. Also you can use any of the AF lenses. But manual lenses should be AI.

    They would work on another system, but not well at all with your 7100.

    you would also quickly come to terms that manual focus and aperture control on a modern camera is not fun.

    Because Registration is 37.5 mm on Nikon and over 45 mm on M42 it should be easy to find mechanical adapters for your grandpa lenses.

    However. The viewfinder of the D7100 is not made for manual focussing. You probably need a replacement focussing screen at least.
