Group buy for ProLock adapter for Sony F3

[Duke M.]

I spoke to Jacek (Optitek) about a group buy for the F3 ProLock. The ProLock is a PL style locking mechanism for Nikon lenses.

Like other adapters it allows the use of Nikon glass. Unlike other adapters the lens is not twisted in. The lens flange will not get the wear and bending of the thin flange pieces with use.

This will be important with heavy glass, lots of lens changes, and to protect expensive lenses. Realistically your lenses are the big investment and should far outlast your camera.

It also has an iris control, but its an external ring with an aperture indicator, that makes G lenses behave like those that have an aperture ring. The ProLock fits onto the F3 in seconds the same as the MTF, PL, Adaptimax adapters. (The picture and price on the website is the for the ProLock for the Red which mounts differently.)

If we get 10 buyers, we get $100 discount each. (Normally $995 for the F3.)
20 buyers and we get $150 discount each.
30 buyers and we get $200 discount each.

I'm aiming for 20 buyers.

I have several people ready to buy. Let me know if you want to join the group.
