I have a Nikon D7000 camera. I have the opportunity to get a Pentax 135-600mm zoom lens for free. I know it would be manual use only, but I figured it might be fun to play around with.
My question is can I adapt this lens for use on a D7000 camera? Would it even be worth fooling with? |

A quick search suggests that you probably can get a Pentax to Nikon adapter, but they often do not allow focus to infinity.
Given the size of the lens and its f/6.7 max aperture, I would pass on the offer. However, only you can judge the "play around with" factor. |

The issue with adapters and manual lenses on DSLRs is that the flange focal distance gets thrown off by wedging an adapter between the lens and the camera... If you use one without a correcting lens, you can't focus to infinity. If you do, you have another crop factor introduced. I used a couple old Canon FD lenses on my 7D for a while. The crop factor was effectively at 2x. IQ was pretty damn good, tho.
I switched to micro 4/3 which has a huge advantage in using manual lenses - the short flange focal distance actually REQUIRES an adapter that moves the lens further away, so it works out awesomely. I've got a couple Canon FD lenses and a couple of dad's old Minolta lenses that work well on my EM-5. Can't hurt to try it out. You can find adapters for $20-30 that aren't horrible. IIRC, the one I used was Fotodiox available on Amazon. |
