Now your thinking like me. How I make money throwing my 18 year old out of the house. Ill take his new VW GTI i bought him about 6 months ago. Think his student loan would cover this. ROTFLMAO
There are some real pluses here astro folks. This thing does 60 min to 1/2000 sec (depending on lens in use)..We can't do that with Sony. 60 minutes is HUGE I say
Hi Guy,
I am not quite sure as to the longest shutter speed that you can set with the original A7r. I know that in Bulb mode as I recall, you should be able to get at least 30 minutes and maybe 60 minutes. I am not sure if you can run the mode for as long as the battery would last. If so, with those large expernal battery packs that I have posted that would allow for exposure times of hours. I just haven't had any success at this point finding an on-line posting of the longest shutter speed for an A7r.
By the way, the A7r as I understand it does better for long exposures than the A7rII due to the operation of the camera switching from 14 bit to 12 bit.

Rich
Both A7R and A7RII have a drop in precision when activating Bulb mode. (in reality it goes from 13 to 12 bit)
However, as you wrote, the A7R performs much better with long exposures as it seems to have less issues with heat.
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!

Anybody here pre-ordering it? I came very close pressing the button but what puts me off is lens selection. I would mainly use it for landscapes and need wider lenses (even wider than the 30mm promised in September).
Whenever they release a 24mm (19mm full frame equiv.), I would re-consider it.
I came close too and didn't, for the same reasons. When there's a 19-21, 28-35, 50-65, 85-100 and 135-150 equivalents then I'm in, as long as those lenses aren't so heavy that I might as well carry the Pentax I have now. I love what I'm getting from the Pentax so I'm not in a rush but if I can lose 30% or more weight I'll do it. For now I know I'm getting essentially the same image quality just in a bigger package. Plus the Pentax is cheaper and has a full range of excellent lenses available, many of which are available cheap as chips second hand. For example my FA200mm cost me US$500 and it does this
....and weight 650 grams. Pentax zooms are heavy but the primes are very light and mostly fabulous. It's how much the whole system weighs that'll make the difference, to me.
The Hasselblad lenses are going to have to be pretty brilliant to make me switch just to get a lighter body.

The big trick here is cooling and being in tempatures that do not cause heat. So depending on outside temps these can very long but those kind of results are best at near freezing to about 45 degrees. Obviously heat causes noise so cooler the better on any cam. I think part of the issue with Sony is just shear electronics packed in a very small space and don't get the breathing room. Now these medium format sensors are designed for long exposures too and they can go a very long time. Back when I shot the CCD sensors you could only go about a minute. Today with CMOS which supposedly runs color by nature they can get up to a hour. If we look at the specs of this CMOS sensor with Leaf, Phase and Hassy I think they are all reporting about the same times and this has a lot to do with the packaging and air channels they put into these backs. I'm not the engineer guy but there is a lot going on design wise too to accomplish this. The A7r for some reason does better here than the A7r II and I don't really have a clear reason why that is. Maybe someone with a engineering background can explain this better than me. 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.

Fred, if you really are serious about buying HCD lenses, I would HIGHLY recommend buying used. If you look at the prices of medium format lenses for both Hassy and P1, the difference between new and used is dramatic, a sign that they were way overpriced to begin with.

Your post got me thinking that perhaps the new X1D being so small could perhaps have more issues with heat than much bigger MF bodies using the same sensor. That would translate to poorer long exposure IQ. It may not be the case but just something that should be tested.
p.18 #10 · Official: Hasselblad X1D-50c Medium Format Mirrorless
This camera is seriously tempting, but I want to see 6 months of results first. I skipped the upgrade to the A7RII so I am due for an upgrade in the next year . I'm hoping it's between this, A7RII, or A9. Like Guy, I'm waiting on Photokina, but realistically, since the A7RII hasn't been out a year yet, I don't have a lot of expectations from Sony this year. Maybe next year.

I agree Fred they closerd the box as they say and with that I don't know if the cooling is they same as a back. I give it a solid 30 minutes though in cool temps. But again this deserves some testing but we know already this sensor will go far longer than our A7r II so for landscape and Astro shooters this is a plus. But agin we need to get down and try this because if your in 80 degree heat your not going a hour with no noise, that I can guarantee you. We have to be very careful about this because heat is noise and we have to figure cut off points. Let's not forget the body, battery all generate heat.

I got a pretty good nose for this stuff and if you keep the AF abilities as a low expectation and sheer speed than this has a lot going on for itself. To me it takes all the bull shit away from what I had to deal with and I love that simplistic approach Hassy did. BTW I'm hearing record amount of pre-orders in 24 hours. That says something as mentioned earlier a lot of folks are going to jump on this . Now I'm glad I have about a 7 year background on this stuff. I was totally into it.

No doubt. I just found a HCD 28/4 on Ebay for $3,200 in great condition (half the price of new). That's close to 21mm (FF equiv.) and is my mostly used FL for landscapes. Currently the Loxia 21/2.8 is my favorite lens. I wish Hasselblad would release a 24 or 28mm instead of a 30mm but I can see how the latter could be more appealing to a larger group of photographers.
What really got my attention for this camera system is compactness and I'm sure many of us would not want to go the route of bigger lenses with long adapters for this system. For my personal needs, I will probably wait until there is better lens choices for the wider range.

On the other hand, Hassy lenses designed for a larger image circle may give us even better corners and depending on the adapter, open the door for tilt / shift movements.

No question . Mirex (spelling?) and Zorek have tilt adapter. Even Hassy has a Flex adapter. Dang I'm going to look at that now it's designed for H cameras

I can see where this is going (based on other recent lens threads by Guy and Fred)... We should all place bets on date and time Guy and Fred each place their orders (regardless of the camera now being wait listed).
