67 to 645 Adapter question

Hi Pentaxusers,
I just bought an adapter that enables me to put 67 lenses on my 645. It was produced (or sold) by a brand called "fotodiox". As thereīs no manual provided :-( - Does someone know it? Is it possible to use the Automatic mod of the 67 lenses reliably? Or should I switch to manual aperture mode?
Thank you!
Ole

Well, 67 lenses don't have auto aperture (though most have automatic diaphragms), so you will have to shoot in av or m mode.

The Pentax adapter contains an aperture coupler, so I'm sure this one will too.

Hi Ole,
another vote for the original (Pentax) adaptor. It has an aperture coupler - so you can focus with open aperture. Perhaps you shout call at Pentax in Hamburg for price and availability ( I donīt think that there a lot of second hand items)

PS: I presume with the Fotodiox adaptor you fix the 67 lens only mechanically to the Ptx645 - there is no coupling. You have to use stop down metering.

Ole,

A Fotodiox adapter does have coupling to the body through the two levers on the back of the adapter. Put the lens in Auto mode and you can focus with the lens wide open. The aperture will close to the f-stop that you select on the lens when the shutter is activated. I have several of these adapters and always use them in this way.

Try looking here, I assume it's the same.

Pentax 6x7 (P67) Lens to Pentax 6x4.5 (P645) Mount - Fotodiox Pro Lens Mount Adapter

I'd love one of these but they're very expensive.

Thank you for your replies! @ Jonathan Mac: If you want it, you can get it much cheaper here:

Amazon.com: Fotodiox Pro Lens Mount Adapter, Pentax 67 (6x7) Lens to Pentax 645 Camera Adapter, FITS Pentax 645D, 645N, 645: Camera & Photo


They ship to Europe. I received it in Germany without troubles. Because it fits in a tiny envelope, the customs did not stop it; I got it tax-free.

I heard that the glossy surface of the adapter might cause visible flare on photographs. Though not having developped any test shots yet, I try to prevent this by having painted the inner surfaces with matte black paint (carefully excluding moving parts, of course).

I got the Pentax version used for less than $50 but haven't used it too much yet.
