deep7: Just curious. I know this file has been pushed. That has resulted in very poor tonal separation in the red clothing. How does that look if you don't push the file? Ta.

Must be the migration through the interweb then - though I have downloaded and looked in a variety of programmes and seen the same thing. Don't lose sleep over it! Thanks for responding, much appreciated.

camcom12: Did you & Mike T. from IR borrow the same A7RII ? Something special about Portland ? (in jest)

I think there was a media event there...

It's not what I'm talking about. In the pushed shadows, the red is either one tone of red or dark grey. For 100"ISO" pushed two stops, that's very poor. Hence my question. If you can't see that, you can't answer my question!

maxnimo: From the samples I conclude that the only way to fully utilize all those pixels in this camera is with low ISO and a really good lens.

It struck me that the amount of noise control/downsizing needed to keep the A7r files as clean as the A7S files meant the detail advantage of the denser sensor was lost in poor light conditions quite quickly - and you had to faff around a lot, using big files and lots of computer power, to get there. Further, the tonal gradation looked to be far from as good.

So my response to "Jonath" is valid for the A7S but not the A7r.

Obviously you don't care about noise as much as I do as nearly all the A7rII images here are grainier than I like.

Well, Rishi, we got into a little argument a while back, when you went to some length to show that a Sony A7r had as good dynamic range as an A7S. I was so curious that I borrowed an A7S and took a big handful of photographs, trying deliberately to provoke the sensor in both sensitivity and dynamic range (I had already borrowed an A7r and had a good selection of tough light RAW files to play with). I then pushed, tweaked and played with the RAW files from both cameras.

My conclusion was that the A7r is quite noisy, even at modest sensitivity, and requires a lot of help to keep a clean file. The more you ask of it, the harder that becomes. Sure, you don't get banding but you do get something close to posterising in the shadows. The A7S, on the other hand, was absurdly forgiving, needing nothing more than a touch of masking even when pushed quite hard. Further, it seemed I could get maybe a stop more highlight recovery, meaning that much less pressure on shadows.

Continued...

Reilly Diefenbach: DSC08432 (Council Crest) should have been taken without exposure comp. You're two stops away from blowing highlights according to the LR histo. That would have made the color a lot better and avoided the noise. As well, we have sensor spots. Glad I'm not the only one :^) This series might have saved me $3200. We'll see!

Knowing your highlights, in terms of what you see on the camera screen (still pretty crude devices, really) comes with practice with each particular camera model. I understand why you would have over-compensated. That said, you'd learn the camera quicker by not over-compensating and seeing what happens!

Except an A7S?

Hmm, the text in the story said to check this out for an out of camera jpeg with some noise reduction. For 100 "ISO", the background is quite horribly blotchy. Or am I missing something?

I see the same thing with the Canon 5DS series...

Gesture: I can get a nice APS-C DSLR kit for so much money. Silly.

I have a very nice micro four thirds kit. I love it. It covers exactly the same range but cost more than twice as much and I don't think it would be as good at the very long end of the focal length range. To get that range at the lowest price, you need three lenses. The point of the Canon is you can do that with one lens. As for price, are you basing this on the announced price or the price that the market settles at? Apples versus apples?

smozes: Long reach is not important in the real world? It's a specialized camera exactly for this purpose. Comparing it with other fixed lens cameras with a normal range is beside the point.

That's like pointing out that superzooms are not that useful in the real world, so one should consider other cameras. A review of a camera like this should already take into account an interest in superzoom by the reader as a given. If the reviewer doesn't see the point, then maybe someone else would be better.

Well, it was a change of tack! Depends also what you mean by "a few mm" and where your starting point is. It's a very nebulous statement at best.

Anyway, the logic of giving up 200mm of telephoto for an extra stop of aperture is the same as saying that a 1.4X teleconverter is pointless. It's not.

stratplaya: So where's the video proof?

That's amazing! It makes that sample video from the Sony A7, which made us go "wow" such a short time ago, seem dated. Though, to be fair, this Canon sensor is a one-trick pony.

In reply to:

Nereo: Um... I'm beginning to think we need a new standard other than "ISO" to measure light sensitivity.

ISO came from the sensitivity of coated glass collodian plates (ISO ~1 !) Then came the films, and it was still easy to keep track that ISO 100 was 4x as sensitive as ISO 25. But now we've got cameras with ISO 102,400 and now 4 million?! Quick: how many stops between 1600 and 102,400?

Since camera sensitivities now exceed two orders of magnitude, why not have a sensitivity measurement that matches? e.g. ISO 100 = 1, 200 = 2, 400 = 3, 1600 = 4... each double the previous level in sensitivity.
This new camera exceeds "16" on our sensitivity scale!

One of my pet peeves is the near universal of the term "ISO". To follow on from the people above, in film days Americans had the ASA standard (American Standards Association) and Germans had the DIN system (the letters stand for something very similar in German). Something like twenty years ago, the International Standards Organisation (ISO) decided it was best to combine the two to give an ISO number. This would be something like 100/21, 400/27 and so on and it's what you still see in the small print on a pack of film.

Ironically, in the digital age, the DIN part of the number is ditched in common usage, leaving the ASA number but retaining the ISO name. Weird.

ThatCamFan: I used to use Canon for many years, only thing that I am going to say which you all called: Perhaps Canon should focus on DYNAMIC Range, I hope they know the word or is it to foreign to them?

Read the text. It will serve you better than being a parrot.
