Nikkor lens compatibility?
Hello everyone, I'm looking to get a digital SLR camera (nikon d3000 probable one, as I'm only want to start with photography). My dad has an old Nikkormat EL with three lenses and I was wondering if any of them work anymore. Do not know much about how to describe the glasses, so I'll put what I see in him. One is Nikkor 135mm 1:2.8, Nikkor 28 mm 1:2.8 and a third is 1:02-HC Auto Nikkor f = 50 mm. If I can use any of these may then consider buying only the body rather than lens + body. Thanks!
If the goal is similar to that http://kenrockwell.com/nikon/nikortek.htm # F (also read what is said about the identification of a non AI lens) yes that can be mounted, but you have to be careful to mount the camera. The rest can be mounted without problems, but will not be in the measurement of the camera.
