I'd imagine it was surface area. If (as we're led to believe) the 645D uses a cropped sensor then it probably does have around 1.7x the surface area of 35mm.

Yves link takes you to a page which says:

"Challenge the next Dream
Super high resolution(?) image the world with a big image sensor. This real ability will be revealed with the CP plus"

Not very interesting I know - but try this page

This page reads:

"In this new product, comparing with 35mm full size it has about 1.7 times more pixels(?)

From one image the data amount is 100MB - you can understand the impressive image quality of the big sensor by just one look at it."

(?) means there was a technical word the missus didn't fully understand herself.

Don't know if any of this will give any clues or not - but there you go.

So Pentax are pushing the benefits of sensor size yet we have forum comments regarding FF that say it is no advantage due to FOV et al.

Hmmmm?

In theory the larger sensor should allow much lower noise. However it depends on how many pixels they try to cram on to it.....

If I had the spare cash I'd be buying 645 lenses by the dozen off ebay now.

There's no debate over whether bigger sensors generally offer better IQ.

Some people don't find APS-C > FF enough of an improvement to warrant the extra expense, bulk of equipment etc. I doubt they'll be queuing to buy 645Ds, but that's for a totally different, and pretty exclusive, part of the market.

From what I've heard of a rumour a year or so ago they wanted to use the Kodak sensor and those are all cropped MF sensors.
It was the 20mp version I believe or a bit lower, don't know what they have, hopefully they are using a bigger one though 30mp would be a sweet spot I think.

Is Pentax that big any more?

Considering FF is still a very small part of Canon and Nikons sales and the people buying them are mainly pro photographers for weddings and such I really cannot see Hoya putting the money into full frame.
That's what I meant. Pentax isn't a large company and can't really afford to produce anything too esoteric. Everything they produce needs to be a financial success or they could be in trouble. Like you say, the FF market isn't big and neither is the MF market. In fact, with the introduction of high resolution FF cameras like the Sony A900 and Nikon D3X I would have thought that the demand for MF cameras is on the decline. Why pay £10k for a camera that doesn't do much better than a £1.5k camera?
MF camera's are very different then APS-C, FF or 135 film, the MF camera has always being their for the artists under the photographers so don't expect super fast AF of even ISO1600 for that matter... well maybe ISO1600 but ISO3200 would be pushing it though.

You're right with that but it really depends on how you compare things, sometimes FF is indeed better but other times the difference is hardly there and certainly with longer lenses the APS-C has some advantages.

It all comes down to how you want to use a camera and for what, the world isn't so black and white as some think.

I'm really looking fwd to see what the 645D turns out to be and more importantly how much it costs... 39MP and just a 1.1 or 1.3 crop effect would be ideal! And if it does match some of the images that are up in places like pentaxforums I'm definately liking the possible return of the sloping MZ-S like top LCD plate.

As some of the older members will recall I still shoot my 645nII a heck of a lot and have pretty much a full set of 645 A & FA lenses to match up with one of these.

It could be exactly the kind of IQ jump I'm looking for from my K10D. For me the big bonus will be being able to still shoot film for night shots, when noise and dark frame subtraction becomes a real pain in the backside.

Fingers crossed it is within my reach!

Maybe Pentax User members in the UK should club together and buy a couple to share .

I agree wholeheartedly.

Lots of film bodies, a couple of digital ones, too many lenses (mainly older glass) and a Horseman LE 5x4.
