It's a long established fact that while I like snapping away, I don't actually know much about cameras. I do however have an awful lot of them and I came across this lens last week. I don't think it belongs to any of my cameras and I was thinking of selling it, but I have no idea what it is outside of what's written on it. For instance, what lens mount is it?

Help please

One more photo for reference.

Hi Ed - to my eye the mount appears to be Nikon F, with the slotted tab on the ring for F and F2 metering. The pins under one of the lobes implies that it's a later lens with CPU communication.

Thanks very much indeed. That makes sense actually as I did have a Nikon setup here for a while - someone brought it over and left it. I moved it on without trying it out and probably forgot that there was an extra lens included in the collection.

Probably Nikon as I think they were the only ones who used the fork to transmit the aperture settings (on the Nikkormat).
Though I've never seen one with a slotted bayonet... but the fork pretty much confirms it.

Nikkor lenses do not have the slot, but the cutout in the outer perimeter gives it away as a Nikkor AI equivalent.
