Somebody can post some shots at 800iso please?
I'm very curious about the result. What do you think about the comparaison between Nikon D3X et H3Dii39 (the same captor as the CFV-39) on dxo website http://www.dxomark.com/index.php/eng/Image-Quality-Database/Hasselblad/H3DII-39?

Hurra
My CFV-39 has finally arrived .
The first I found were 4 big "coughing spots" on the sensor .
I could clean them using the supplied e-wipe tissues .
Yes John , the split screen is different in the landscape position . Funny .
But it works .
Up to now , everthing else seems to be ok .
More results to follow .
I did not receive a battery and charger with the CFV-39 .
This seems either to be a goody from the dealer or beeing handled different
in the countries where you buy the CFV-39 .
I will unfortunately not be able to post my first test images , as I have a crashed system after installing SNOW-LEOPARD on my MAC PRO3 .
None of my printers worked after the upgrade and some other applications just don't do anything .
The restore from a backup failed . So I just sit here with a basic equipped LAPTOP and can receive e-mails and can paricipate in the forum . That's all .
I will try my best to post images asap .

Very many congratulations to both Jim and Jurgen for being the new proud owners of he CFV39. I hope Brad will follow soon.
On the 800 iso, I think it is not a true 800 iso but a 200 iso pushed by two stops in Phocus post processing. I am saying this because when I open the .fff files in another software it is completely under-exposed. Maybe I am wrong.

I understand you feel cheated. That is perfectly understandable.
Maybe look at it this way:
If it works out fine why bother how this higher ISO was achieved.
In fact all manufacturers go the same route.
As far as I understood the pushing is done when going from RAW to JPEG.
Theoretically over 20.000 ISO is possible at 1/4 of the original amount of MP with cameras offering 3200 ISO now.

Thanks Paul and JAT, this is really interesting.
So, what is the true iso of the CFV39? Would it be correct to assume that any sensor has only one true iso, and that is its base iso? Any higher iso is achieved through pushing the exposure in firmware or PP software. The quality of the higher iso is then determined by the firmware and software's ability in keeping noise, color and sharpness in good control. The limitations of the sensor is then mostly determined by quality and size of its pixel. This, if true, would mean that the CFV16 is more capable of having its exposure pushed, which then means that while the CFV39 has a 800 iso capability, the CFV16 has a 1600 iso capability.
I am just assuming all of this.

You might find this essay from Luminous Landscape informative. The writer talks about problems with Snow Leopard and Epson printers, and how he got them resolved. Seems, for the time being, that Rosetta must be installed.
Read this article - perhaps it will solve some of your current issues with Snow Leopard and your printers.

Good luck.

Saad, Hasselblad quotes that the natural sensitivity of the sensor is 50 iso. I think any higher iso numer is reached through the software and any electronic stuff in the sensor. I must admit I am surprized how clean the pictures are a high iso numbers.

Thank you very much for your valuable answer .
Unfortunately , it does not help me any more , because my system is crashed due to the incompatibility of RETROSPECT EXPRESS and SNOW LEOPARD .
I will need help to get me back to OSX 10.5.8 , where everything worked fine .
I think , it was not very wise from APPLE to launch SNOW LEOPARD when there are still many incompatibilities with other applications . Not only EPSON printers . EYELIKE is also a candidate as well as others .
I hope , that my system will be back to where it was before by Wednesday .
I will report about the progress .

I'm glad I read this before it would have been too late!
(hope you fix things quick) I was, too, tempted to upgrade, the marketing and webpage at apple is too good to be true.
the mac i use is amazingly perfect.. there is nothing short of great with it, and having said that, i still feel the 'need' to upgrade after reading the benefits and specs at apple.com
if something is perfect why mess with it?
ummmmm....

You are right. It is still a Mac of course.........

My understanding is it is ISO 50 pushed in software with the CFV-39... Still, as was mentioned in another thread, I am not too concerned with how it is done, as long as the results are satisfactory, and with the samples I've seen, they very much are.
Thank you as well for the well-wishes. A delivery truck should be pulling up this morning with a much-anticipated package. I will let you know!
Best regards,
-Brad
