DT's IQ4 Tech Camera Test Teaser

[dougpeterson]

The new BSI sensor in the Phase One IQ4 150mp produces dramatically less color cast on tech cameras. DT has recently completed a test with the Rodenstock 32HR and Schneider 43XL on both the IQ4 150mp and IQ3 100mp Trichromatic.

Below is a teaser:
- Row One: IQ3 100mp with 43XL; 20mm left/right. Color Cast Reduction = OFF. Light Falloff Correction = On. Lots of color cast.
- Row Two: IQ4 150mp with 43XL; 20mm left/right. Color Cast Reduction = OFF. Light Falloff Correction = On. Much less color cast.

If you're a tech camera user, you're likely jumping up and down with joy. We'll wait.

The raw files, along with analysis by Doug Peterson, our Head of R+D, will be posted in the next couple days. Stay tuned to PhaseOneIQ4.com or shoot an email to [email protected] with the subject "IQ4 Tech Cam Tests" to be notified when the results are posted.

Wow Doug, that’s amazing! Love to test out the new back. What are the file formats that are available on the new back? 16bit? 14bit?, etc How large are the RAWS?

Oh, crap. :facesmack:

 

[stevenfr]

Amazing

Oh, crap. :facesmack:

Do we see a horse ranch for your wife in the near future?

I'll prep the guest house with clean linens.

See you soon!

:ROTFL:

A pretty dramatic result - would love to see how the 28 and 35 fare too.

 

[f8orbust]

Oh, and if I had an IQ150, I'd seriously be taking a look at used S/K lenses.

I have a SK35XL which will be worth a gazillion very soon :grin::grin::grin:

 

[tjv]

Good God that's amazing... Pity I won't be able to afford one for another million years.

 

[Ed Hurst]

Interesting indeed! Is there any data/evidence that allows us to evaluate the matter of crosstalk?

 

[med]

Very, very nice. Glad I bought low on the 43 XL, although I’ll need those ducats to put towards a 150 now!

 

[stephengilbert]

And yet there's little interest in my 43mm Helvetar. Maybe I need to ask more for it.

 

[Jeffrey]

So, Ken, has Dante convinced you to dive in with the rest of us?

 

[earburner]

Wow that's quite a difference..

now we have to see how fluffy the lead time is for the upgrade...

With a webinar happening tomorrow I guess they are nearing a shipping date..

 

[kdphotography]

I need to sell my home in Carmel and settle into my new home.

After that's done---IQ4 will seem easy.

I've got plenty of time to sit and ponder. First world problems. It's not like I'm skimping too much by holding onto the IQ3 100.

 

[vjbelle]

You sure aren't:grin: The 3100 will remain a workhorse staple for years to come...

Interesting extra information is that the SK 43mm supposedly was shot without a center filter. Usually on a shift that much with that lens you definately would use the CF.

Agreed. However, we do not have the center filter, therefore can not use it .

If you're in NYC or LA and wish to loan us one...

 

[Aviv1887]

We can figure something out Doug. I'll send you an email.

Falloff correction is turned on so you're not seeing the falloff you would normally see without a CF. It is slightly misleading of course for some to turn that on, but falloff is physics and can't be avoided unless using a CF, so it is what it is. With the better dynamic range of CMOS sensors... I personally would probably avoid the hassle of a CF and correct in post.
