Is there any difference between these cameras beyond resolution?

I'm about to order the 40, but from what I can get a h4d-31 and a D800 for the price of the 40, which is bloody tempting.

Is it the same sensor, just less pixels?
 
I'm not sure about the difference between the H4D-31 and H4D-40. However I saw this image last night on twitter. The H4d-40 on the left, D800 on the right. They are 100% crops

There is a difference in High ISO capabilities between the two - and I'm sure from memory one is a newer technology sensor

See, to me those are night and day in difference, but I'm sure others would disagree. That being said, makes you wonder how good the d800e is going to look. Probably pretty close to the 40

Yeah, that's what I read, but I can't get definitive data regarding the sensor. Weird that there's no info.
 
With the H3 the 31 uses a completely different sensor from the others. Higher ISO is better but it's limited for long exposures.

Not sure if the 4 follows the same pattern.

You could always ring the Pro Centre - they will know. I'm down at their studio tomorrow....
 
How much do you really want to know about the sensor....?

Reading a little on the web, it seems the H4D-31 is basically a H3DII-31 plus that science fiction focus thing. H4D40 and up is pretty much a different camera. The 40s and 50s use a chip made by Kodak, the 31 uses a different chip made by Kodak and the 60 uses a chip from Dulsa.

Unless you really want the true focus you might prefer a second hand H3DII-31 and a box full of D800s.

But srsly, call the Pro Centre. I'd be amazed if they didn't invite you down to try their toys if you're seriously interested.
 
Hey, thanks Jonathan, I happen to have a Hasselblad rep coming to my studio with both, but my concern is being "wowed" by whichever one I have in my hand at the time. I imagine using them both will feel completely identical, and you know how it is with things like this: It's only after you've used them a lot, or you know someone else who has, that you really begin to understand the little differences in the tech.

TrueFocus is important to me, if only because it's yet another thing that separates it from a DSLR (I'm keen to have as many new experiences as possible, given the price), so I guess if it's just (just!) a H3D, I might as well spend the bit extra and just get the 40.

But at least I now know it's definitely a different sensor. Thanks dude.

I hope that wasn't put out with the aim of making the D800 look good.

It won't be, because it can't be without some kind of miracle lens on it.

It's not about pixels or resolution, it's about contrast - or lens MTF. The higher the resolution, the lower the contrast (MTF). That's why, even if you have the same number of pixels, the larger format always wins because the lens has to work less hard to deliver a given level of sharpness.

Full frame always beats crop format, and medium format always beats full frame, and large format beats medium format. It was always thus, all other things being roughly equal, and until we get a big jump in lens performance it will stay that way. Nikon's claims that the D800E can rival medium format miss the point, but it does beg the question of just how much sharpness we actually need.

I thought the same thing until I opened the file in photoshop, selected the D800 side and did a 50% unsharpen mask on it and now they look identical to me. Not sure, what you do reckon?
