What is the maximum speed the H3DII-50 and the H4D-60 will write if the CF card is not the limiting factor?

Great question!!
When I got the new Sandisk Extreme IV Pro (16GB), I performed a quick preliminary test. At a read/write of 90MB/second, this card is amazing.
I have been waiting for this next leap in CF card technology. I was able to shoot non-stop for 58 captures, then is slowed down for 1-2 seconds and then continued on. Capture rate was 1 every 1.1 seconds.

Thank you!
Sounds like 60MB/sec. The new Sandisk Extreme IV 60MB/sec is half the price of the 90MB/sec card.
Even if you know the writing speed of the H4D you won't tell  

Best

Hi, Paul, thanks... it works.

The capture icon is greyed (unavailable) in live view, so I have to exit live view before taking a picture.

I there any "one click" way of taking a picture? ...

closing live view
re-setting your taking aperture
taking the picture
viewing the picture for approval

...or any other sequence of actions I might want to macro program?

I have been busy this week, and have not tried it on my view camera yet.

Paul, can you answer a basic question that I do not se discussed on an Hasselblad web-site:

What is the refresh rate of the Live Video feed from these backs? That is, how many fps? My curiosity is of course about how good is it at keeping up with at least modest subject motion. From what I understand about the Full Frame type of CCD, I expect it to be rather low.

I think it is officially and actually about 1 frame per sec... but in low light (poorly lit in door) it takes several seconds to build up a visible picture.

So, about like taking a succession of frames in "motor drive" mode? A serious question then: how useful is it?
Without having tried it, it would seem that even manual focusing on a completely stationary subject would be frustrating with such slow feedback.

I tried it and manual focussing (a must for 300mm + 1.7x) works good. I used the mircostep-buttons for focussing in the phocus software. focus quality is shown in an extra window and makes it easier, too.

While I haven't yet tested on a 50, you'd be surprised that it's really quite easy to use. Knowing that you're absolutely assured to get an in-focus shot this way, live video is worth the inconvenience if the subject matter allows the time it takes.

Its about 1fps.  

Focussing is made much easier (as mentioned above) by being able to focus the camera remotely via Phocus.  

I would also not compare it to a 'Succession of frames in Motordrive mode'.

Those who use it find it incredibly useful.  Without being able to focus remotely I believe this use would be somewhat diminished.

Thanks for the various replies: so it is for slow, steady, precise focus control: fair enough.

P. S. What I meant about "a succession of frames in motor drive mode" was only that the frame rate for Phocus Live Video is about the same as the frame rate for actually taking pictures.

Also, Live Video mode is ideal when the camera is out of reach (i.e. up high or positioned away to get the correct POV.) Major time-saver.

Since this image displayed is the actual focal plane on the sensor, focusing is much more accurate than viewing through the viewfinder (who messed with my diopter settings again? Gahhh!)

Refresh rate is fast enough to move and compose - but more like flying a helicopter than an airplane - slight delay from real-time. Once you have done it, it is routine.

No time limit either.

True, you are correct in theory, but the practice feels a little different!

But yes, you would not want to try and use LV on a moving subject.  That might be a challenge.

Years ago I bought a Manfrotto agnoscope (a ten metre tripod) which came with a cctv system to view the screen of a v-sys Hasselblad... and now I have working live-view, I am looking forward to using it. ...ideal for houses, architecture and landscapes when the foreground gets in the way.

Live view is also use for very low camera positions (now that we have to do without a waist-level finder).

One of the next bitz o' kit on my wish list is a cherry-picker, so that I can mount the ten meter mast on the 14m cherry-picker and take pix from about 75ft... and I want a remotely operable robotic powered sliding triple stitching back for my sinar so that I will be able to use the back off the H4D-60 to take some nice 150 Mpx landscapes. ...anyone been there and dun that?

You can get a waist level finder for any of the H cameras. They aren't very expensive.

...well that is an advantage over the Phase, with a fixed prism.

I used the quadstitch of kapturegroup with the Back of the H3D-39 and a sinar p2. I sold all this stuff, because i found it inconvenient:
- in fact the overlap has to be more than 20%, otherwise programms like ptgui or cs3 have some problems to build a perfect stitch
- getting front and back of the camera absolutely parallel is very difficult for optimal sharpness over the whole picture
- color cast is annoying, too.

I switched to stitching landscape by turning my integrated system (H3DII-50) on a tripod and stitching and correction of the movements in ptgui. This works perfect for me as long as it is landscapeing, maybe it is not an option for architecture. My biggest pictures this way have up to 280mpx (for example with 300mm + 1.7x I made 15 exposures composed to a third of El Capitan wall, Yosemite, 5.0 meters by 2.8m and you can see the climbers snap-on hooks at their belts).
