Canon EF and RF Lenses – All Autofocus Motors

Yeah the in-body motor thing is only for the older Nikon lenses, I don't think AF for that is still supported if you're using Z-mount adapters. Nikon seems to have a few similar AF motor technologies like the canon ones in this article.

turnsout Thank you very much. Trying to understand complex things has always fascinated me. Indeed it takes a lot of time (rd. 1.600 hours for the complete series of Canon lens chapters) but its people like you who drive me forward. I don't have a donation page yet, I never thought it would be used :-)

You could always physically mount them but there were compatibility issues as Nikon added functionality over the years. It was a tradeoff.

Too bad Nikon practically stopped making DSLRs

Oh yeah, that’s even better, totally agree, but it doesn’t negate my point. I don’t think Canon’s 30 or 40 years would be matched by a hypothetical present-day camera upstart, let alone Nikon’s 70 years.

The traditional Nikon mount has a small screw that is turned. The camera autofocus speed is limited by the amount of torque that can be applied to the screw - which can make focusing some of the heavier lenses slower.

The "AF-D" lenses have contacts back to the camera body that communicate distance information (that is in turn used by the camera body to calculate flash power).

The G mount lenses remove the manual coupling for the f/stop which means that only bodies that can control the aperture from the body can use them. My FM3A has no aperture control on the body and so with that camera, I unlock the aperture ring.

The AF-S camera lenses have the focusing motor in the body.

VR in Nikon is done in lens. https://kenrockwell.com/nikon/80400vr.htm It needs to - you can't jiggle the film around to keep it in the same place.

The impressive part of Nikon's compatibility isn't only the "you can use an AI-S lens on a modern (professional) body, but also "you can use any of the F mount lenses on an old body" (the G lenses don't have the f/stop ring and the E lenses have the focus motor in the lens).

While it appears that Nikon has mostly shifted to E and G mount, third party lenses are still being manufactured for the F mount.

Nikon lenses will mount on any Nikon body, but that’s sort of where the compatibility ends.

Their f mount autofocus lenses are a variety of standards that are not at all backwards compatible across eras.

Most shops that offered still photo rentals in my city have gone out of business, and it's a major city. I used to be able to count on renting a big telephoto that I didn't need to own, for a few hundred per weekend, but these days I'd have to take a long drive to get to the one remaining shop.

Agreed. EF's short flange focal distance can also be easily connected to Sony to utilize dual ISO. Indie uses manual focus anyway.
