Phase One P65+ vs Hasselblad 50MS test

[ziocan]

What a stupid argument.

99% of my professionnal work is made in 4 shots and 16 shots modes. I'm allways triyng to use the best aperture for each lense, to have the best image quality. And f22 is never the best aperture ! Why would I use f22 to capture a painting ? To have less details ?

I think that the best comparative test is done with the same platform and the same lens.

You gave a stupid answer.
A paint is practically flat. Instead a pair of sunglasses or a bottle of perfume is not, therefore the f22.
Photographers do shoot a lot at f22. Not only objets but also people.
Just think of beauty cosmetics photos. if you want to have the tip of the nose and the ears in focus with a 150mm lens on MF back, we need f22, because f11 or 16 will not make it.

Hillarious thread!    

I use a H3Dll 39Mp MS, almost exclusively in 4 shot mode. I love it and that's all that matters.

99.9% of professional work is reproduced at A4 or smaller.

This site is tradionally peopled by obsessive, pixle peeping, landscape shooters and this thread (accepting that there are many pros and dealers contributing) is typical of that mentality.

It doesn't matter a damn "if mine is bigger than yours". All that matters is that mine does exactly what *I* want it to do.

Multi-shot blows away single shot pixel for pixel. So, the only relevant comparison, in my opinion, would be single shot vs. single shot using the *same* lens, as someone correctly suggests above.

If you are trying to earn a living from photography, surely it matters if you customers are happy with the results and prepared to pay for them?

I think that many of us here target that .1 % of the market - partly as anyone can do much of the 99.9% "adequately" with a sub £500 camera.

I admit to being an obsessive IQ conscious landscape shooter... does that make me mental?
If you are not IQ conscious, why do you use a 40Mpx back in  4 shot mode?

Are you comparing to MFD single-shot or Canikon AA work?

4 shot might be OK for studio, but for landscapes with thing moving, a 60 Mpx MFDVC is better, with or without shift-and-stitch.

When I get my H4D-60, I will invite P65+ users to come to Warwickshire so that we can use different backs on the same view camera with apo-digitars.

Why is it that all camera can't do multishot? What is it in the hardware that enables it?

Cost
Most people use single shot most of the time to avoid have to use a tripod

What is it in the hardware that enables it?

The sensor moves between shots.

The pixels you get are "full value" pixels rather than Bayer effective pixels.

[Jason Denning]

So even on 4 shot the sensor moves? I knew for a 16 shot it moved, but not 4 shot.

For a 4-shot the sensor moves by exactly 1 pixel for each shot:

- 1st shot = initial position, then moves right by 1 pixel
- 2nd shot, then moves down by 1 pixel
- 3rd shot, then moves left by 1 pixel
- 4th shot then moves up by one pixel, to the initial position

The 4-shot captures 2 times the green, 1 time the red and 1 time the blue colour information.

 for a 16-shot it moves by 1/2 a pixel each time: 4 times initial position in the left direction , 4 times down, 4 times left, 4 times up to initial position, capturing each 4x4 steps 2 times the green, 1 time the red and 1 time the blue colour information

Attended event at Fotocare last week where H3DII-50ms was demonstrated at length.
LOVED the combination of Live Video + the ability to manual focus via arrow controls within Phocus software.
PERFECT for focus bracketing + Helicon Focus software achieving extended depth of field.

VERY impressed.
