RE: 645 - 6x7
Are the 645 and 6x7 lenses interchangeable? eg: could I use my 105mm for the 6x7 on a 645? You need an adaptor to put 6x7 lenses onto the 645, and you lose lens automation. 645 lenses don't project a large enough image circle to cover 6x7, and I don't think the 645 flange to focal plane distance is long enough to allow a 645 lens to work on the 6x7 anyway.

Hi, Kevin and all. Sorry for my previous post that was empty. 6x7 lenses used on a 645 body via the 645/6x7 adapter allows you to maintain the lens automation and open aperture metering in the following modes: - aperture priority - manual - TTL flash automation You loose these modes (because the 6x7/67 lenses lack the A setting): - program - shutter priority - aperture priority automation achieved when the aperture ring is in A (only 645 lenses has it) Hope this helps.

Re: 645 - 6x7
if you pay for a *full frame* 645, P645 lenses will be less than your sales tax. i mean, ALL of them, together. mishka On Mon, 14 Mar 2005 13:32:04 +1100, Kevin Waterson [EMAIL PROTECTED] wrote: This one time, at band camp, William Robb [EMAIL PROTECTED] wrote: You need an adaptor to put 6x7 lenses onto the 645, and you lose lens automation.

Re: 645 - 6x7
Yes, with an adapter. Just like you could use it on a k-mount. (It won't work in reverse).
