The maximum exposure time of 60 minutes gives a hint.
I like the idea of ditching Bulb mode and allow exposure times to be set directly longer than 30 seconds. In case one wants to stop a long exposure, it can always be done by turning off the camera and the file will be saved. On my 5DSR the buit-in Bulb timer saves the day, but setting all shutter speeds directly would be even simpler.

Hmmm thanks Matt

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).

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).
Makes total sense Matt.
I'm sure Sony engineers are aware of possible downfalls caused by IBIS like larger/heavier body, higher heat (noise) hitting the sensor with longer exposures, etc.. It will be interesting to see how they deal with these issues in upcoming models.

It may still be complete nonsense
For example, maybe no camera manufacturer is thermally coupling the sensor to the body and they're all cooled by air contact alone (heatsinks/heat pipes add size and weight (and cost)). The easiest way to test the theory would be to look at long exposure noise with the A7II - does anyone here own one and fancy doing a test?

I prefer to keep Bulb mode. I am old school and I still use a cable release and will often shoot varying exposure times such as when I am shooting fireworks and rapidly changing lighting such as animated christmas light displays. These are times that my exposure lengths will vary and the last thing I want to do is fidgit with turning the camera on and off to end my exposure. Not to mention I would need to touch the camera and introduce shake from me touching it.
Like yourself I enjoy having the built in bulb timer on my 5DsR and I use it lots but it doesn't cut it for me when I am trying to capture shots with quick varying shutter speeds.

Actually I remember that Jim Kasson did some controlled tests on this and if I remember correctly his tests show that the A7II heat effect was far less pronounced when compared to the A7RII even though both share the same IBIS unit.
He believe that the difference could be either caused by differences in sensor technology or that the A7RII just puts out more heat. Since the battery life is pretty much identical between the cameras, he concluded that the 'sensor' is the culprit. If that's really the case, that's good news for future upgraded bodies with newer sensors as IBIS may not be the source of the problem.

BTW: Guy just sent me this info via email. I believe it's from getdpi. It contains Hasselblad's answer to many questions we may also have..
Dear Hasselblad,
I'm really excited by your new camera and wish you the very best with its launch. The feature set looks great and it seems so far to be the perfect replacement to my much loved Mamiya 7.
I would like to ask you though if you may clarify a few details about the X1D for us:
1: Will the HTS 1.5 work with the X1D and H lens adaptor, and will adjustments be transmitted to metadata for automatic corrections in Phocus?
2: Is there plans to impliment an electronic shutter feature so that people may take the liberty of using the X1D on such platforms as the Cambo Actus, or indeed adapting third party lenses without leaf shutters?
3: Is the refresh rate of the live view feed in the EVF 30fps, and is this specification limited by the capacity of the sensor itself in that it can't output any quicker and retain the same level of detail?
4: Can you please confirm here that the autofocus point can be moved across all areas of the sensor area?
5: Lastly, does the X1D have a focus peaking function to aid in manual focusing and checking the precise focus point?
Great to hear. Here are some of the answers I can give at this very moment. All of our Swedish engineers are already gone celebrating the Swedish Midsummer - the biggest Swedish holiday during the year here in Sweden
1: Will the HTS 1.5 work with the X1D and H lens adaptor, and will adjustments be transmitted to metadata for automatic corrections in Phocus? - Yes, it is in the plan. If it works fine without compromising optical and image quality, the feature will be introduced.
2: Is there plans to impliment an electronic shutter feature so that people may take the liberty of using the X1D on such platforms as the Cambo Actus, or indeed adapting third party lenses without leaf shutters? - No, X1D will work only with the new XCD lenses or with all the existing HC/HCD lenses using the adapter. This is mainly to secure the the highest possible image quality which is key for Hasselblad.
3: Is the refresh rate of the live view feed in the EVF 30fps, and is this specification limited by the capacity of the sensor itself in that it can't output any quicker and retain the same level of detail? - X1D EVF performance is outstanding, no need for any quicker rates in here. There are EVFs out there with higher fps but the actual performance does not live up to Hasselblad quality standards. We suggest to book a demo and check out EVF's performance on your own at www.hasselblad.com/x1d
4: Can you please confirm here that the autofocus point can be moved across all areas of the sensor area? - It will, yes. At this stage it is central single focus point, but we are about to launch selectable single focus point feature.
5: Lastly, does the X1D have a focus peaking function to aid in manual focusing and checking the precise focus point? - Autofocus metering via contrast detection with instant manual focus override.

Good points. Who knows, maybe this camera enters bulb mode if you dial the exposure times past maximum, like some other cameras that don't have a 'B' on the mode dial.
A semi-bulb mode would be pretty cool. Dial in the maximum exposure time, and if the shutter is pressed during exposure, let it end.

So, we won't have an electronic shutter on the X1D. Forget about using lenses without left shutters on it.
Also, I believe there is no MF peaking option and currently there is only one focusing point in the center of the frame. Firmware updates will add more points. (unclear how many)

Not only that but the answer given, unsurprisingly (given Hasselblads more recent history), points to a very high probability that we will never see a focal plane shutter version nor even the ability to use an electronic shutter option in the future (even when possible with the sensor) with non Hasselblad lenses. They want to keep it a very closed system to maximize profit (maximizing image quality is marketing BS and code for this). This will likely never be an alt platform.

Then they won't have my money. I am sure market interests is high enough that other manufacture will chime in. Their loss, not mine.

Yes, their loss. Do they really think they will earn more by forcing people to stay only with their lenses? I would have thought that opening the system up would generate more interest and eventual sales, than keeping it closed will.

That worked for Sony (open system strategy). Whether this closed system/ "protectionist" strategy works for Hasselblad (or the U.K,) will depend on what other players do and timing. If Hasselblad are able to deliver a decent lens lineup within the next year AND a competitor does not introduce a similar, yet open, platform/ camera within that time, it might work. I think the chances are rather high though that we will see more competition in this space sooner rather than later.

Is any system open? AFAIK each system is closed and 3-party just made adapters anyway, no reason not to make an adapter with a shutter built in.
Certainly some systems are much more open than others. The chances of seeing an adapter with a rather complex and expensive electronic leaf shutter built in that is compatible with a wide assortment of adapted lenses (even of the same mount) sounds slim to me . I'm not holding my breath on that one.

They do provide two most essential focal lengths right from the start, at attractive prices. For most buyers, that should be ok, and I don't think other brand adaptability will be a priority.
. I first thought this was a DR comment when I read it as "this is a 12-stop process."
