Unless the camera system had autofocus in the body (which, as far as I've been experienced with, really only is medium format bodies) the lens always has had autofocus. Canon, Nikon etc.
The problem is that a lot of adapters for old lenses only feed mechanical (if even) instructions to the lens, for aperture and the like, and don't send over autofocus instructions.
Luckily manual focus will work just fine.
- rangibaby 10y agoNikon lenses have only had autofocus motors since about ~2000 (which is not a long time ago in terms of lenses). Nikon's compatibility with old lenses is quite stunning. They did one major change to their mount in the 70s but every mid-range or highrr camera since then has had 100% compatibility with any lens. Metering, aperture control, everything. The AF system still works too. You just have to use your hand as the AF motor and the camera will give you an indication when it thinks focus is correct.
- ptaipale 10y agoNikon AF lenses (which came to market in 1986) don't have built-in autofocus motor; the motor is in the camera body. Those days they were the film cameras, but also modern DSLR cameras have the motor (with the exception of cheapest consumer DLRs, i.e. the D3000 and D5000 series).
