What happened to ISO 50 on P30 ?

All productsheets states that P30 should have ISO 50. Now when I have gotten my back I find that it´s lowest ISO is 100. :?
Am I missing something ?

(ISO 800 is not important for me as a portraitphotographer. I chose this back partly because it could shoot ISO 50. If shooters want to use ISO 800, I think a DSLR is a better choice for them and that PhaseOne and others should stay away from ISO 400 and higher. It is super quality I want shooting Low ISO.)

Jorgen,

Correct - the printed P30 Spec Sheet is incorrect stating ISO 50.
The Web Site Specs states correctly:

P 30 highlights (for technical details refer to datasheet)
· Incredible 31,6 Mega pixels
· Rectangular format sensor 4:3
· Fast capture rate (45 frames / min.)
· High sensitivity (100-800 ISO)

This P30's sensor is a native ISO 100, although a more sensitive ISO 100 due to micro lens, a minimum ISO 100 nonetheless.

Regards,

All info stated ISO 50

All info provided by PhaseOne stated ISO 50 until someone changed it. All PDF's i downloaded, one early this autumn and one later last year, states ISO 50...

I think it is a lame excuse that it is native ISO 100 when it has been advertised as a ISO 50 back...

PS. It still says ISO 50 on the downloadable datasheets. 8)

Agree

I have to agree that it does state 50 on the \"P 45 datasheet - English\" downloadable right now, and on initial DC Review it states the same.

Even if this is incorrect, I would find it very misleading. Jorgen does have a valid point here...

Bearing in mind the cost of these upgrades, I have just moved from H25 to P45 and the price quoted was £3000 lower than the final upgrade cost when the P45 was ready to ship. I would not be allowed to get away with such fluctations with the facts with my clients...

Correction

Given the fact it is impossible to do an ISO 50 on this chip, I'll offer another lame excuse... it was a misprint in the Spec Sheet ... Human Error ... an oversight.
Therefore, if this remains a significant issue, then please pursue through your Dealer for resolve.

Ah ha... I now find the PDF Spec Sheet with the incorrect information at our web site. I will notify those that can edit this document and make it accurate.
Thank You for bringing this to our attention.

Cheers,

Don´t want to be Mr.Annoying but it also says ISO 50 (for all models) in the manual (P-series Reference Manual) which is downloadable from Phaseone.com and in the provided printed version that comes with the back.

I don't care about ISO50 or even saw it before i ordered my back, but thought you should know that the manual has a misprint anyway ...

when you searched on internet, all the articles about the P30 will say it can shoot at ISO 50, that's a very big mistake from you.

your company should add a note or an apology on your first page.

This is a mistake made by our marketing dept, for that I do apologize.
It has been communicated out to all dealers of Phase One camera backs so the right information is communicated all potential customers.
As it has been clarified before, I will clarify it again.
P30 is using microlens technology where by sensitivity has been boosted on f-stop. This means that P30 have a native sensitivity 100 to 800 ISO while all other backs have sensitivity range between 50 and 400 ISO.
