I have removed your e-mail address from the listing, for your own security, as web bots often skim forum messages for such information

You cannot autofocus with those tubes (or any tubes that I've ever seen) -- there is no screw-drive there. However, they do pass-through aperture info and allow camera control of same (at least in theory).

this one actually has screw AF coupling so it will AF, have a closer look at the pictures.

I have the same set. It does not have AF, those are just the screws holding the mount on (notice they are phillips heads). Or maybe you are looking at the mounting pin. There is no slotted drive. Look at the last picture. If there was a screw drive it would be at 9 o'clock.

yes you are right, just looked at mine and the coupler is at 9 o'clock indeed!
so, why it has "FOR P/AF" written on it?

According to a 1977 post on Photo.net Kenko did in fact make a screwdrive AF set of extension.tubes for Pentax, Nikon, Canon and Minolta as well as the much more common manual focus Auto Exposure tubes. They also sold a single length AF extension tube 25mm extensions in AF/P mount. These were branded UniPlus tubes.

Perhaps the seller will post a sharp macro shot of the screwdrive shaft coupling which would mate to the camera mount at the cameras 5 o’clock position.


[Edit] THE ABOVE DOES NOT APPLY AND I CANNOT DELETE THE POST IN A FS THREAD. SPOLOGIES FOR THE COMMENT - THOUGHT I WAS HELPING.

For that mount.

Yeah, come to think of it the Uniplus tube does do AF, and there might be a 2x TC with removable glass that does AF. I've never seen a full set of tubes with AF though if they do exist.
