At least their aggressive marketing and insane pixel obsession will get those over-inflated prices down! - (along with Canon and Nikon chomping at the heels of 31Mp!!) .......$9000 rebate on a H3DII 22Mp!!??

The pixel wars and the ever deepening credit crunch are conspiring to make the next year or so the best time ever for buy into a reasonable pixel count MFDB system, if you have the work or spare cash.

$9000 rebate on the H3DII/31MP kit....seems like a good deal if you have a spare $18k.

They do have the image circles needed, the adaptor will work with the 28, 35, 50 and 80mm lenses, +/-18mm shift, +/- 10 degrees tilt, +/- 90 degrees rotation.


Thats good news,Nick.Thx.

Do you have confirmation that the lenses can retain 'infinity' focus?

I really hope they've done this by going to full 645 (which would bring it almost exactly to 50 million pixels) rather than by squeezing more into the 36.7mm x 49mm sensor.

Yes, we need larger sensors more than smaller photosites.

I wonder who else has developed a back with this new sensor? I doubt very much that Hasselblad is the only one.

Yes, that perfect match is intriguing. Of course, it could also be that a rumor-monger computed that 50MP on exactly that assumption. Or that Kodak has gone to a nice round 6 microns in its current format (and maybe with its new CMOS technology, for which Kodak has claimed very large format capability through stitching.)

It's a Kodak sensor so I would expect Phase to announce a back soon..

Hi Mark
I've asked the question of Gothenburg and will report back, I am certainly under the impression that the adaptor (it's not a body) will allow infinity focus.

I distinctly remember that the 28mm lens has an image circle just large enough to cover a 48x36mm sensor so movements won't be possible.

I don't see how this would be possible with the H3D anyway. The camera is designed for a frame of 48x36mm, hence the 'full frame' nomenclature.

The information above is direct from the product manager but I'm sure you're right and he's wrong

Actually, yes.

Which product manager? Apparently I know more about his products than he does, and I'm not even a Hass H user.

The information about the 28mm lens is in an interview with Hasselblad's CEO, Christian Poulsen.

But perhaps more convincingly, have a look at the 28mm lens product info sheet: "The HCD 4/28 mm lens is designed solely for digital use. This means that the lens is designed
for a format of 37x49 mm
and does not cover the film format (41.5x56mm)."

Even more evidence: look at the MTF charts. Performance drops off fast on the corner of the digital sensor (at 30mm).

well according to the german website link , hasselblad announced a 50mpix H3D and a T/S adapter for the 28/35/50/80mm lenses....
i wonder who makes the sensor and if kodak makes it why doesn't phase have it?
and how the hell do they fit a T/S adapter between the lens and camera and still keep infinity focus? and there is still the question of coverage, as noted here before some of these lenses just cover their format.....
but again this is coming from the company that had the first fullframe digital MF system...so maybe they just squeeze an extra 11mpix out of the 39mpix chip and the T/S only applies to the center of the image and distances up to 2ft....
either way....the sensor that would get me excited would not fit into the H3 and the lenses would not cover it...so i can't wait for the full US press release and the usual email bombardment...

Nick-T, TechTalk please chime in.

I'm just wonderin' out loud:

-why it's called an H3DII-50, and not H4D-50 instead.
-if the 50MP sensor is a 37x49 version of the micro-lensed 31MP

John,
I had the same thought, but Linos/Rodenstock makes a 45mm + 55mm, and Schneider makes a 47mm instead of a 50mm.

and you never can squeeze a symmetric or nearly symmetric lens as the 24/28/35 schneider or roenstocks on a mirror based camera.

If the adapter is for the existing Hasselblad H lenses, then NO way in hell there is any room for movements. If the adapter is for some other brand of lenses, perhaps intended for larger format uses, i.e. Schneiders, then it is quite possible to have movements. Our OP cuts and pastes some fairly obscure info with no mention of what 28,35,50,80 lenses the adapter is for.

Sorry posting between shots.
The adaptor is for H lenses.

I just hope that these are things that I can use with my existing H1 and H2.

Even if they weren't I would still be interested and would report on them fairly. Remember, my beef isn't with the company or its products, just with some of its management's marketing policies.

I agree, But I fear H1 & 2 users are going to be left out in the rain.
Sure do hope i'm wrong.....

I can hardly believe , that there will be an adapter for the 28,35,50 and 80mm lenses .
The image circle of these lenses will be too small to allow a shift of 10 or even 15mm .
Also I doubt that the DAC tool in PHOCUS could correct that much vignetting .

I have heard a rumor as well , but that was not about an adapter , but a WA camera with the ability of shift and tilt and special WA lenses .

I am very curious , what the future will bring .

It will focus at infinity. Also I'm told it will work on h1/h2 which is very good news. Nick-T
