Dr_Jon: BTW I'm assuming it's the same sensor as the Pentax 645Z, so you can compare DR right now...

Rick - what? I said I thought the Sony MF sensor was dual-gain, Rishi said it wasn't, he said it was noise reduction and you don't do dual gain at ISO 12,800. I said that presumably means Pentax are cooking (i.e. modifying by adding noise reduction) the raws and thought that would be a big thing. I also pointed out the D810 appears to change gain at ISO 12,800 so if people don't do gain changes there is that cooking the raws too? None of this was criticising Bill's methodology, it was relying on it.
As to the PDR chart he has a 5Dsr at ISO 2500 as 7.16 stops and the 645Z as 7.57 stops, the difference is similar as ISO rises. How is that two stops difference? I specifically said they were close at higher ISOs, for low ISO I compared to the D810, where you have 11.53 stops max vs. 11.75.

Random Photographer: It costs GBP. 160 (~$200 USD) to get rid of the Leica logo... Let that sink in.

It's a bit like cars, a particular option on a Mini may cost X and if you want it on a Porsche it will be 4X, even though both manufacturers will use the same third-party product (e.g. Bosch) to implement it.

So you're saying the D810 doesn't switch at 12,800 and it's just noise reduction? Also you're saying the 645Z is cooking the raws? Oh and the D810 as well... actually that's a big thing!
Could be a hard sell perhaps?

The video is old (2 years) but really cool... plus moon-walking on point!

It's a shame the paper's going, but I'd have thought a tethered camera and a decent printer will get something similar in a ball-park-the-same time-frame, but for 1/25 the cost per print. The Polaroid does make for more of an experience though...

BTW I don't think I've shot a Polaroid in the last 15 years, but I suspect my lifetime total is in four-figures somewhere, although much less for casual use (100-200 maybe). I'm not sure I miss them. Although if I'd been shooting 20x24 I might... (depending on the cock-up rate).

@Rishi Sanyal Hang on - so you're saying the bump part-way along the DR curve for the 645Z (ISO 12,800) isn't dual gain? What is it then?

Chris2210: It will be interesting to see what battery life is like - my guess is that it will be in a similar ballpark to the GH4 [I note that's 500 shots against its predecessor's 540]. That rating surprised me because I would have pegged the battery life of my GH3 as comfortably into the higher hundreds. It's certainly nowhere near as frustratingly short as most other mirrorless cameras where you certainly need to have a spare for a full days worth of shooting. The GH cameras do of course also benefit from the possibility of an additional unit in a grip.

I suppose it's a minor niggle, but having to switch batteries mid-shoot is a pain - hopefully this camera will have the stamina last a moderate day's worth of shooting.

photoreddi - sorry if I wasn't clear, I meant the GH4's on-board flash. CIPA standard in English: http://www.cipa.jp/std/documents/e/DC-002_e.pdf

@Rishi Sanyal - but presumably we don't know the H isn't dual-gain? The sensor certainly supports it so I'd assume it is.

P.S. that's what rental is for...

kadardr: 50 MP is no snapshot territory. You have to think several times. Production job. The alternatives for (or similars of) X1D are the RX1RII and the Sigma Quattro SD H. The former lacks interchangeability and have to be rigged up. The latter has a 1/180 flash syncro speed, so not for fancy flash work. But the price of X1D is really at the pro level, and these others are much cheaper. As for the X1D lenses the 24, 35 and 70mm equivalent (30, 45 and 90mm) set is good enough as a start. A 150mm tele and a 100 mm macro could be the next (may be final) step.

I think the Hassy is a great development, although at rental rather than purchase pricing (for me, anyway).
With luck someone will do a more mass-market equivalent - while hand-made in Sweden is nice, made by robots in Japan and 1/3 the price would work just fine for me...

Pontoneer: Smaller than the average DSLR ? Unless the model in the photos has tiny hands , that thing looks pretty big to me , certainly bigger than my Pentax K-3 , which I'd say is on the big side of 'the average DSLR' , albeit smaller than some others out there .

Canon 50MP 5Dsr is 930g with battery+card, they quote 725g with battery for the Hassy, so over 200g (7oz) lighter.

Indeed, 1/2000 flash sync at full power is a key thing for some folk...

Nikonandmore: It's a great camera, I just wish was full frame MF. These interim sensor formats like the Leica S, make no sense. And I still don't think it's made by Hasselblad. Someoene else makes it for them for sure.. and the new lenses too. And let's not forget by the time you attach MF lenses to this "small" compact body, it will be a large package.

And can someone explain to me why every imaging product now-a-days is always Xs, Ds and 1s? It's trully appalling the lack of marketing imagination. How many people necessary to come up (and approve) a camera with the name X1D? Hysterical..

It impressed me how long people had been naming cameras before Canon came up with the A1, so I don't think originality is marketing people's strong suit.

BTW what's full-frame MF? 6x4.5, 6x6, 6x7?

I'd have thought the main alternatives were MF cameras like the 645Z and the 50MP Canon 5Dsr, which has very similar DR as ISO climbs, but much more sophisticated in everything else (more fps, much better AF, endless lens range).

I've taken sort-of snapshots with a 5Dsr, no harder than using a D7200/80D (lower pixel density so camera movement issues slightly better if anything).

The CIPA ratings involve a lot of use of on-camera flash, so you usually get quite a few more "in the real World".
BTW 500 shot battery life is with the EVF, it's 530 with the rear panel, which always strikes me as odd.

StMal: only 2 native lenses. and its not that fast. dslrs lenses are faster

It's compatible with a big bunch of manual focus Hassy lenses...

Not sure the DR is as important as the amount of light gathering...

Halina123: Weather sealing and no OVF. Large sensor and high price.

Am I correct in thinking that the main two markets for this camera are.

1. Landscape photography.
2. Studio. Fashion/wedding/portrait photography.

I often see people (although usually only one per day) out and about shooting MF in London, I expect they'd love something this small and high quality.

Rish - yes, but you'll get less shot noise, which I find does tend to give something of a smoothness to a shot even when it isn't immediately obvious. It will be interesting to see what H have done with highlight headroom and tone curve...

Too expensive for me, but an amazing development and I'm really glad they did it. If someone gave me one (and a lens) I think I'd use it rather than flog it...

BTW there's a lot of technology in there, I wonder if they got some good CDAF technology from the same people (surely it isn't all in-house, who knows)? Of course sensor readout speeds may play a part too.

In reply to:

ScanSpeak: So is this a full frame sensor?

JimW-203 I think FF sensors have a pretty exact correlation to the exposed area of 135 film (both 36x24mm). Actually m43 sensors are basically 110 film size (17.3x13 vs 17x13) and crop sensors to APS film is close too (film 25.1x16.7 in 3:2, vs 23.5x15.6 for most recent Nikons).
I suspect wildbild is quoting the size of a CCD MF sensor, although I've no idea which (they vary a lot, the Phase Ones are mostly 53.7x40.4).
