Same fps: the limitation is that essentially a FF type CCD must read-out of every photosite, one [or up to four] at a time; no skipping, little room for parallelization.

Indeed.  Plus you would need a pretty meaty processor in camera to display a pretty worthless live video.

Japan always loved White cars... slowly creeping in here in the UK too.

White cars was last years trend for the nouveau riche over here. The white Range Rovers,X5/6, Cayennes & Panamera's were in short supply.

Hi David
Yes if you have a few minutes and can get a 31 and 40 to do some side by side ISO testing, that would be really helpful.
thank you in advance.

We announced and showed the new HC50II and HC120II.  Both of these lenses have been completely redesigned optically.  The exterior dimensions are the same.

Performance on the 50 is much improved and in particular with the HTS.  Lens Correction calculations have already been made and are included in Phocus 2.6.

The HCD120II lens has an increase in resolution and an improvement in axial chromatic aberration.

Availability and pricing, please.

Hi Am,

Take a look here...

http://forum.getdpi.com/forum/showpost.php?p=250058&postcount=6

Some excellent comments regarding a user's comments on his experience of both sensors.  I agree 100%.

I will try to see if we can get some direct comparisons.

Hi David.

Sorry to be a bit off topic but while we're talking about sensor differences, is the Kodak chip in the H4D-50(MS) the same as the H3DII-50 or has there been improvements?

Thanks, Gareth.

David, the Fuji version of the H has always been black. My recollection is that it looked damn good.

Hi David,

what are the options to power a H4D40 or 50 on a view camera if you do not want or can not tether to a laptop?

This has proved a popular solution...

This is something that has to be addressed by hasselblad. Not having a battery to power the back is a big issue for me.

You can also use the imagebank II which is the Hasselblad solution. The other solution is much cheaper which is why people are also using that.

BTW, I am selling an Imagebank II which I don't use anymore...

Sorry, Let me clarify. I meant a tethered power solution that is reliable. Because some macbooks have limited firewire power, there can be insufficient power to the back.

Another possibility from Hasselblad is the CFV-39 (and now the CFV-50) DBs, which are battery powered and can be used on a view camera with a V-system adaptor.

Hi, David...

Did I see something about a battery option for the H4D-60, or did I imagine it or misinterpret something?

Hi Jonathon,

It isn't actually a limited power issue. There is nothing wrong with the power output per se from any of the Macbooks. Ie There is enough watts to power the camera.

The issue is that part of the signal that maintains the firewire connection can suddenly drop, thus breaking the connection. We have been looking into this into a lot of detail along with Apple - so it's good we have their attention.

Suffice to say it doesn't seem to affect all users so it is a strange 'feature' of the Macs.

To cure it until Apple come up with a solution then use a FireWire repeaters or something like the Lindy FW800 cable with a built in repeater. As these contain additional firewire circuits it seems to prevent the signal drop.
