2 and 3 look like they fit special plates.

1 looks like the normal one to me. I can only find it on a sort of fake site, but it shows the normal 3/8" connector on the bottom..

I can't see any problem with No: 1
The extra two holes probably take locking grub screws but aren't really needed. I don't have them on the pano head.

..

The other two versions are double (back to back) for holding TWO PLATES either at 90deg to one another for say panos or parallel to extend a plate.

Speedgraphic list the parallel one (very cheap) Note the two knobs...

The one you want has 1/4" and 3/8" connections...

The pin that stops the plates sliding off can be seen on the enlarged photo. It just hits the solid end of most plates stopping it sliding off. A lot of plates come with grub screws that stop them sliding anyway.
The pin is on a spring and will retract if you happen to put a solid plate on, but these are very rare.

I might drill and tap a stud on the Sunwayfoto one I've got. The position isn't too critical it just acts as a buffer stop.

Novoflex stuff is superbly engineered.

Panos with a Pentax 645D and Novoflex.... All I'm short of is the 645D ...... Oh! and the 4 Legged Tripod

The Giottos ones seem to all hide the spirit level when in use.

For use with an L-Plate on a small tripod I bought a Sunwayfoto one.
They are quite well made and take any plate.

There's nothing QUICK about the Arca plates. You have to slowly unscrew the release and they (and the camera) slip off very easily unless you put grubs screws in as stops. This further slows down removal. Your also stuck with a big plate underneath the camera.

I've got about 5 Novoflex MiniConnects which for safety require two levers to be pressed before release. Putting on is a doodle they just click in place. You can also QR a camera strap.

If I need to use a Plate or the L-Bracket I have a Panorama-Q Head with a QuickConnect Coupling piece on the bottom. Takes seconds to change over.

Novoflex and Arca plates are almost the same and usually interchangeable.

There's also a Quick head for the plates with a safety pin ....

Nothing wrong with them shots Steve and is it me or
does the 1.7x make the players look prettier

I wonder why they have used a white line for the line up mark when everything else inc. other TC's have a RED DOT? :

Note the video is from Pentax Forums not Ricoh.

Edit: The new 55-300mm also has a white line.
The old one had a red dot.

It's the new Ricoh Sell-Up Training for shop staff

Someone goes in buys a TC and the sales person says.....
"Would you like a lens and a body to go with that TC"

--

When comparing body prices with other makes, don't
forget that the SR is built into the Pentax body
