Does this work with old P series and IQ series backs?

XT Features
With an IQ4: Full electronic integration, automatic metadata (lens/movement/aperture), automatic lens-correction, X-shutter compatibility, native shutter release etc
With an IQ3 or earlier: works like any other tech camera (a plate of metal on which you can attach traditional tech cam lenses and a back)

Comparison of GFX 100 with 23mm to XT with 23mm:

Doug, just to let you know, there is a typo that states that the Phase One XF is actually a GFX with Canon 24mm TS-E II in the article "The XT is smaller than you think"

Okay, I'll bite. 

1.  No autofocus, correct?  Not going to lie, if I buy a small camera I want autofocus.  It would be difficult to justify a smaller camera with limited movements that will not allow me to fully use the image circles (I regularly get 15mm to 30mm with my lenses, contrary to what the article implies, and would be more so with an IQ4 150) without some other pluses. 

2.  I only glanced at the article but did see automatic lens distortion corrections.  Does this mean that the back records the shift and will automatically remove the unique "mustache" distortion of the Rodenstock lenses taking shift into account?  If yes, will we see a firmware update for existing backs that will allow us to manually record the shift on the back if we are not working with this system?

3.  Is the DT LCD shade available to purchase without actually buying the system? 

4.  You have a Compendium Mount offered as an accessory, but I did not see a compendium.  Are you eventually going to offer a compendium, and, if so, how much better would it be then the standard, say, Arca Swiss compendium that does not work well with wide angle lenses? 

5.  This seems like a on the go camera where you are working a little faster.  One caveat to slow you down though is the need for lens cast corrections.  Is this now built into the firmware?  If so, how does it hold up to performing the correction manually?

Correct. This is a manual focus camera.

Correct. Encoded movements. I'd suggest reading the articles all the way through; lots of nice little touches on this system. :)

If yes, will we see a firmware update for existing backs that will allow us to manually record the shift on the back if we are not working with this system?

I would expect that to be added at some point in the future. Though manually entering and manually updating those values will not be nearly as nice as having them automatically handled by the XT.

Yes. We're coming off several very very long/busy days and going into a couple more with the launch of the XT. But I would expect to add the DT LCD Shade for Phase One IQ backs to our eStore in the coming week or two; do note that we expect to offer it as a bundle at a price lower than stand-alone. If you're eager for one you can call your DT sales person and they can process a purchase manually.

Poor old Alpa with the FPS - they got there first and were years ahead of this:

IQ back with independent focal plane shutter, accepting tech lenses. The same Rodenstock ones.
Combine it with an STC body for movements if you want. (Or not if you don't)

They were a 'partner' of Phase. Now we know what that amounts to.

4.  You have a Compendium Mount offered as an accessory, but I did not see a compendium.  Are you eventually going to offer a compendium, and, if so, how much better would it be then the standard, say, Arca Swiss compendium that does not work well with wide angle lenses? 

The DT Dovetail With Compendium Mount for the Phase One XT is a DT Exclusive Product and is described here: Phase One XT Accessories. It keeps the compendium out of the way of the grip/shutter, leaves that accessory mount point free for other accessories (without having to stack accessories), and keeps the compendium from rotating when you rotate the XT. All around once you see it you wonder why it wasn't built in in the first place (clearly the answer being they were quite obsessive about reducing weight and size on the XT; which worked as it's smaller and lighter than a GFX 100).

The compendium shade itself is a Cambo part; we are Cambo dealers, but the shade itself is not exclusive to DT.

Here is the compendium shade mounted on the XT using the "standard" mount (the DT mount would instead come from just under the camera, and thereby not block the shutter/grip).

Today: The XT encodes the movement in metadata and C1 suggests the closest matching LCC from your library of presets.

Future: I fully expect the LCC to just be handled automagically in the same way the dark frame is handled automatically on the IQ4.

Always: The amount of color cast, even without LCC, is darn low on the IQ4 sensor, to the point of being irrelevant for many lens/movement/user combinations.

This shade is great doug!
Thankyou I've need one of these all summer and will when I'm in Australia in a couple of months.

What is the expected retail?
Thanks.

Comparison of GFX 100 with 23mm to XT with 23mm:


To be fair, the accessory finder should probably be removed from the GFX 100 for this shot.

Are there any plans for an accessory finder for the IQ4? I immensely prefer the articulated GFX finder experience to that of the LCD display on the back of the camera.

I think that's fair.

Such comparisons are always fraught with inequality in one way or the other. Another point of inequality is that the GFX doesn't have an L Bracket attached, which would be required to sort-of match the built-in rotating dovetail of the XT. But they do help to quickly put a system you've never held in person into perspective.

I think it's safe to say P1 has some extraordinarily interesting ideas in mind on how the XT system can be expanded as regards the UI and image review / viewfinder. The XT is a platform in which P1 plans to invest considerable time, effort, and development money. More than that I cannot say :).
