Win a Pentax Limited Lens: Raffle Now Live!

Hello everyone. The image below is of a Vivitar Series 1 100-400 4.5-6.7 Auto Zoom mount. Is that for a Minolta? Note the zoom drive shaft hole near the 6 o'clock position. The lock pin hole seems to be near the 10 o'clock and the 'red' docking guide is over by the 1 o'clock. I can't seem to match my AF Pentax lenses to those features. Thanks.

It's not Alpha mount, Nikon maybe? Typical crappy goodwill pic.

Definitely Nikon AI (or some variant thereof). The giveaways are the "nub and arc" protrusions from the bottom aperture ring. Those protrusions can be dremeled off; the lens can be mounted (press-fit) onto PK pretty easily. For a secure fit, cut a slot or drill a hole for the PK locking pin to engage. Aperture and focus will be manual only.

It does look like Nikon AI (without rabbit ear) mount to me... the giveaway is the black plastic section at the base of the mount.
