The press release says "The camera back's full-frame CCD delivers more than twice the resolution of any single-shot, medium-format camera back currently available. This sensor - measuring 36.86mm by 36.86mm ...".

Since the Hasselblad's film size is 60 by 60 mm, I would hardly call a 37 by 37-mm CCD "full-frame".

Oh well...

I wonder what the size relationship is between a CCD pixel and a typical grain on a film? If the pixels (transistors) on a CCD are smaller, then it may work out to be similar in the end, even though the CCD is smaller. I would suspect that film still has the advantage overall.

Regardless, I would love to see the output of this! I bet it would produce killer 8x10 or 11x14 prints.

Coincidentally this was discussed in the Pro Forum:

Tyler:

There is a misunderstanding wrt the meaning of the term 'full frame'. This does not refer to the size of the frame but rather the technique by which the device is read out after exposure. I believe that the alternate technique is called interline readout and is generally required in video applications of the CCD having to do with the requirement of taking a fresh exposure at the same time as the previous data readout is taking place.

I am eager to know the cost. There are an alful lot of RZ's laying around in camera exchanges. This could be really exciting if it is in a reasonable price range.

grain on a film?
I was reading a scanner review in a magazine recently that said you can make out individual film grains with a 3200dpi scanner.

What I find interesting about this CCD is that it's 36mm x 36mm - if they cut off the bottom 36mmx12mm, they'd have a sensor about the same size as a 35mm frame, thus they could put that into a 35mm package (instead of medium format), and have no conversion factor needed for lenses - now THAT I'd be much more interested in!
 
Barry - I have an RZ, and they're great cameras. They're big and heavy though, quite different to 35mm! If you can find one cheap, it would be a good buy.

I'd love one of these backs for my RZ, but I'd be VERY suprised if it cost less than $15000 - and compared with the current backs available, at that price it would be a bargain. For an amateur like me, film + ProPhotoCD scanning gives me great quality 72MB images at a much better price.

Yes, but you loose one generation of quality on PhotoCD being scanned from the film. With digital cameras, you always deal with the first generation (actual source) of the photo.

Since the only Hasselblad it will function with is the 555ELD (newest model) all of us with 500CM's will need a new body. I bet we see a promotion similar to that of the 560/660,free Mac G4 deal ! > > Buy a DCS Pro Back and get a 555ELD body FREE.

Thank you for the clarification, Fred.

However, in conventional photography, "full-frame" has always meant the entire film area, and to use it differently without a clear explanation, is just bad writing.

It's a sensitive area for me because my much-loved Hasselblads are packed away, awaiting a full (6x6 cm) frame digital back. In the meantime I am forced to use a CCD the size of my little fingernail (and I always hated the blasted little 35-mm format).

Cheers,

You are right. Even at this price and with that resolution, (and provided the quality is better than current offerings) any current digital backs will become completely obsolete overnight.

I like what I've seen of the design, it seems very practical, even the way the LCD tilts towards the viewer and the possibility of adjusting its position for awkward angles. This LCD apparently has live video, so framing the image should be very quick and easy. Plus you can zoom and pan the image to check on your focus/exposure.

And the posibility of using it tethered and untethered is great too.Although it is not a full 120 frame, it will not require mega buck wide angle lenses for most uses unlike at present.

The file size is just what we've always demanded as I am sick of hearing these camera back reps telling us that 17MB is all you'll ever need!

The most important failing of ALL current one-shot backs is their awful colour antialias rendering in small detail areas, such as small text on soft drinks cans, perfume bottles, etc which at the moment only multi-shot cameras can reproduce properly.If Kodak has solved this problem, I will certainly consider purchasing this new back, provided it is not more expensive than today's offerings.

I am so glad that I decided to wait, considering that I almost purchased an expensive and awkward compromise that I would live to regret.
