Possible to get Canon EF lens to work on Pentax DSLR?

Julie · 10-13-2011, 05:23 PM

With autofocus?
If it's possible, does anyone know where I could purchase one or where to start looking?

Thanks!

No. There is not even an optically corrected adapter. In addition to the difference in registration distance the EF mount has an electronically controlled aperture. There is no autofocus adapter for any mount (except Sony A on the Nex 7).

Just buy a Canon camera.

Abandonment is unnecessary. Just go bipolar. On good days, shoot Pentax, On bad days, shoot Canon. On indeterminate days, order a pizza.

Everything is possible.
On the other hand forget it. There is no point in buying a brand A camera with brand B lenses not designed to fit brand A.
Adaptors are not everything. You can fit Canon EF lenses to work on Sigma SA (DIY solution), you can adjust the flange focal distance by repalcing the mount, ... everything is possible, but completely pointless in the end and for sure more expensie than just buying a camera to go with the lens you want.
