I noticed a while back 6x7 to 645 lens mount adapters got discontinued.

I've yet to read that 6x7 glass is adaptable to 645D.

Anybody seen an official claim that 6x7 lenses are adaptable to 645D ?

If so, please link me ?

Thanks

Yep with adapter. No AF, A-type I dunno (does 6x7 support Program AE??), and aperture lever Yes AFAIK

yup, 67II body supports fully programmed AE with multi-segment metering.

67 to 645 adapter still available in Japan, for about $220.

This adapter lets you mount a 67-system lens onto a 645NII or 645N camera body, and offers Aperture-Priority AE operation.

Hey! Don't even THINK about putting a 67 lens on a 645D. We don't need you guys jacking the prices of our lenses cuz you're too cheap to get a good digital one.

On a more serious note. If you're gonna spend $10k, just buck up a few more thousand and get lenses for this camera.

I will take my 67 400/4EDIF over the 645 AF400/5.6 any day. Beyond 600mm the 67 with adapter is the only way - that was why Pentax never made 645 lenses longer than 600mm

Well, for those of us with a nice collection of P67 lenses (11 of them in my case), no reason not to use them on the camera many of us have been waiting years for......at least until the day Pentax releases the ultimate medium format digital camera....the P67D!

Oh don't do that to me!

I've been swapping from 67 to 645 glass for the past year. the 645 is a year or two away financially for me....if they drop the 67d....

I know, I know.....I'm just thrilled to see the 645D come to life and will be even more thrilled on the day I can afford to buy one.....but I don't think I'll ever give up the dream of a digital P67. Can you imagine the IQ of a 6x7 sensor?!?! Maybe 60-80 megapixels......some of those big "fat pixels" (9 microns or more).

I'd need some serious disk space...

Maybe a RAID system with several terrabytes and a small Cray supercomputer to process the images.

Now if only the photos I made were worthy of such a setup.

Oh well, fun to dream of it anyways....

Pentax stated in the "645D first impression and interview" thread that the FA lenses were compatable, but I would have thought that they would have been happy to indicate that all 645 lenses were compatable. Is there something that is going to prevent 645 A lenses from working with the 645d? I can't think of why technically that an A lens wouldn't work, but this is relevent in this thread as it could impact 67 lenses...

On the DPReview post announcing the 645D in the Specs section under "Lens Mount" it says "Usable lenses: Pentax 645AF2, 645AF, and 645A mount lenses"....so I'm pretty sure the Pentax 67 lenses with the correct P67 to 645 lens adapter should work ok. At least that's how I've interpreted it.
