Apparently, the camera is already backordered for the rest of the year! Of course, we don't know how many units that consists of or how many Hasselblad will be making a month, etc.

So the Hassy foes adopter has a 1.5 focal length
• For the HCD 4/28 Lens
• For the HC 35, 50, 80, & 100 Lenses
• For H-Series Digital Cameras
• Allows Tilt & Shift
• Increases Effective Focal Length 1.5x
• Digital Chromatic Aberration Correction

Not surprising at all. I expected it and the used market will be all these backs, tech cams and such will grow larger on the used market. Might even steal some used H glass too. Hmmm

Come on Fuji, show us what you've been slaving away on. If there were any fears of doing a mirrorless MF camera on Fuji's part, I think the X1D reception may have removed those fears for Fuji.

I spoke to Zeiss recently, and they have had "a lot of demand" for Otus in FE mount. This shows that using large and heavy lenses on compact bodies appeals to more than a few crazies (I being one of them)

What Guy is referring is really usable long exposure. He tested this sensor and could get very usable images at very long exposures. That's not quite possible with the A7RII. It's a confetti fest!

Having in body image stabilisation makes heat dissipation much harder as what you really want is a big metal heat sink in direct contact with the sensor. This is in conflict with the requirement to have the sensor move around quickly!
However I'm not sure if this is the whole story - can anyone confirm if the A7II has the same issues with long exposures? If not then I suspect there's something else the design of the A7RII sensor that's responsible (the thinning required for back-side illumination perhaps, or simply the increased complexity).

I wouldn't mind the 100/2.2 on the X1D. Heck, I wouldn't even mind a dummy adapter for the 100/2 Summicron-S since I probably won't be able to sell it (assuming of course they add electronic shutter in firmware updates).
Come on hassy release a 65/2 lens for the system and I'll give you my money!
(well unless Fuji comes out with a MFD first, since I tend to like fuji glass.)

I just had a RANDOM thought... So the Hassy X1D uses Nikons TTL system right? Does that mean I can use a B1 in TTL mode with a TTL-N remote? (I've been away from Hasselblad since the H3DII days so I have no idea how stuff works with them.)

Adam I'm guessing that is exactly correct. It is a Nikon TTL and in one of the videos it was stared you can use a SB. That would confirm it to me. Sounds like Hassy is licensing Nikons TTL which was a smart move.

Matt I don't want to get to far deep into this because some of it is by design of the chip itself on how they are getting long exposures it's kind of a trait that MF OEMs have been doing for some time but you make a interesting point. Let's take IBIS it's very possible it's generating heat because the motor is holding it steady for a long exposure and that would generate heat, could be why the A7rII is not preforming as well to the A7r. I don't know the answer here but that is a very good thought. I'm kinda lost why this is anyway as we never came up with a answer between the two sensors.

That is for the U.S. market: Perhaps there will be stock available elsewhere.
"He would not divulge any sales projections or monthly production figures for the X1D, but he did say that the entire U.S. allocation for the remainder of this year was sold out by the end of the first day of dealer availability. (In other words, yesterday U.S. Hasselblad dealers placed orders for every X1D that Hasselblad Bron will import to the U.S. this year.)"

I just know we kinda hit a wall badly with the A7r II. The backs and different sensor build can go on for quite sometime depending on the heat factor. Getting close to a hour exposure can be a very useful tool.
Maybe because the A7r uses a later generation EXMOR sensor. Perhaps the differences show up more for longer exposures. Here is the quote from mttran from my earlier link:
"All BSI (EXMOR R) FF structure (A7rii/RX1rii) sensors were based on FSI (EXMOR - 3rd version with shorter pixel depth). The deeper pixel depth of A7R ( FSI EXMOR - 4th version to boost the DR) has not been retrofitted into BSI (EXMOR R) version yet but it will be in the next BSI (EXMOR RS) version .
We expect a nice DR upgrade in whole iso range when this happen."
p.19 #17 · Official: Hasselblad X1D-50c Medium Format Mirrorless
Very interesting. I know it does have to do with pixel depth as the new MF sensor in these MF backs is a different build than our Sonys. This is where this stuff gets over my head as I'm not the engineering type. I freely admit when it's time to get off the bus and ask directions.

As a side note about heat, I would think this X1D is starting out from a very good place given the entire body is made from aluminum. If it's designed correctly, one would think that would serve as a giant heat sink.

No question in my mind one reason it is aluminum . Makes total sense. Most backs are aluminum as well. I think they mentioned the body is made out of a solid block too. So it should have a very strong build quality to it as well.. Hassy makes nice gear

I think you missed the point, it's not that the IBIS motors are generating heat or anything like that, it's that you can't thermally "connect" the sensor to the camera body efficiently in order to remove heat, and at the same time enable the sensor to move.
The sensor in a system with IBIS is effectively surrounded by air (otherwise it would hit things as it moved) and air is a relatively poor conductor of heat (that's how double glazing works).
