On Sony Alpha 7R II Review (2088 comments in total)
In reply to:

zerlings: I have the A7II but don't like it much (e.g. control, colors, AF speed). The A7RII seems a very advanced camera but is it much different to the A7II?

Thank you. You could try lowering the colour noise reduction and try to get a better average skin colour some other way. I'd have to take a look at the RAW file. I've not had to deal with this specifically recently but I used to use "selective colour" adjustment in photoshop, the reds are adjusted by default, slide to add some yellow and maybe remove some magenta. Skintones usually have a Y:M balance of at least 50:50 (except wind blown faces, thinning skin, high blood pressure which is why I sometimes still need to do it) so a check with the eye dropper afterwards to see if you are in the ballpark of Y>M. I think the additional problem is that it makes it difficult to judge color temperature and tint as you may be tempted to tint towards green just to get the skintones less magenta but neutrals end up with a green cast. I did ask one couple if the best man knew he had very high blood pressure because I'd struggled with the Y/M balance, turned out he was on already on tablets. :)

Oh btw, the Sony A7RII is exceptionally good at maintaining colour at high ISO even in extremely warm light (camp fire, tungsten with warm coloured shades).

I you a seeing reds turning towards magenta at high ISO... In low tungsten light the blue channel is underexposed. Less blue, more yellow. Since noise is uneven you get speckles of yellow. Camera tries to target this yellow noise by processing the image to remove saturated yellows. This upsets the yellow/magenta balance in reds, remove the yellow and your reds turn magentaish. First saw this in a fuji f11 near 10 years ago.

On article Sony brings uncompressed Raw to a7S II, a7R II and... (569 comments in total)
In reply to:

The Lotus Eater: There seems to be a fair amount of concern as to whether Sony will offer lossless compressed files with these updates - I'm sure not many people want unnecessarily large raw files.

The terms lossless/uncompressed and lossy/compressed seem to have become almost interchangeable throughout this whole saga, to the extent that I suspect Sony's press team either doesn't understand the difference or hasn't communicated it as well as they could have.

Hopefully we can assume Sony's engineers will deal with it properly and to the satisfaction of everybody. Well, almost everybody.

But this lossy compression algorithm is nothing like mp3 compression. What if 99.9% of music tracks compressed fine but 0.1%, those with a triangle instrument playing in them, introduced farting sounds over the top of that instument. So its great for most things but Tubular Bells is going to sound like a bad trip to the toilet.

In reply to:

Frank_BR: After examining the details of ARW, the Sony RAW format, I am convinced that it is a very good RAW format. In particular, I don't think a lossless RAW is absolutely necessary.

The ARW format has the following strengths:

1) High efficiency, just one byte per pixel
2) effective resolution of 13 bits for small levels
3) great simplicity, which allows on-the-fly encoding
4) virtually invisible artifacts, except in very special cases when artifacts are provoked by a heavy/forced PP

The criticisms of the Sony RAW format are concentrated on item 4, and these criticisms only appeared after a few experiments revealed the visibility of artifacts in underexposed images of startrails that were submitted to strong pushing. It is very important to note here that the artifacts always appeared in combination with noise, which became highly visible because of the pushing.

A proposal to fix the "defect" of the Sony RAW format is next.

The compression artifacts are visible unless you only want 11stops of DR. You can't fix the raw convertor unless you get it to paint a pretty picture where there is insufficient data. Slow, inaccurate and totally ridiculous when you could simply not screw up the data in the first place.

I still like the camera, been using it for over a month now, I had one of the first in the UK. However, on two occassions, the lossy compression has been a big issue.
Nothing like as minor as the dpreview samples. Affecting the image in over 100 places. I've messaged Richard and Rishi but not heard back. I'm happy to supply them the RAW file.
What you need is
1) an image with a lot of detail (the image is compressed to 1MB per 1MP whatever the content of the image)
2) an image with a lot of high contrast edges (because of the bizarre compression method)
The moon image only has a handful of high contrast edges and most of the image is sky. It doesn't show anything like a worse case.

Excellent camera for a lot of uses, truly awful RAW file format.

On article Sony Alpha 7R II: Real-world ISO invariance study (370 comments in total)

Check out the two tree trunks on the left hand side. Notice the one without a light behind is fine, the one with the bright shop window behind is barcoded.
Who would come up with an algorithm that compresses the more noticable details in an image? Its a ludicrous compression scheme for a photograph especially when the size reduction of the file is so small.
You do need a high dynamic range scene with high contrast edges to see it but the camera would be capable of tackling these scenes without the compression issue. Took the shine off for me when I found a very strong example of the issue in the first week with the camera (visible with far less of a push than here).

I'm happy with the camera overall and the combination with the 55mm is amazing.
The lossy compression can be a big deal though if you do want to make the most of the dynamic range.
Your example doesn't bother me, I got far worse examples in my first week with the camera. Thanks for raising the issue at least.

I'd like to see it used with an orange filter on the lens and compared to 1) the same filter on a bayer DSLR and 2) compared to channel mixing an image from a bayer DSLR with no colour filter on the lens.

In reply to:

Emacs23: Obviously marketing material for amazon to help to sell tons of low quality APS-C crap. Funny to see bunch of nerds here in comments who either have several systems on their shelves or ones shooting crappy pictures who is now talking about "it is photographer".
Obvious: in case of the same mount there is no need at smaller sensor at all, just make larger with higher density sensor and this will end up in the way D8X0 eliminated any need in 16Mp APS-C or A7r made old 16Mp NEXes obsolete in terms of IQ.

If you think APS-C is "low quality" then you must think 'full frame' is low quality at ISO200? There is also more DR on a 16MP NEX than on a 5DIII both at ISO100. The quality is great despite there being cameras that are even better.
The 'need' for the APS-C? With a much lighter and smaller camera bag I'm getting out and shooting far more often. A full frame fisheye lens weighs as much at my 5R + fisheye combined.
Which format is better very much depends on what you photograph and how you like to photograph it.

Photo_AK: "... a single-user subscription is available for 10,00 USD / 8,00 EUR per month for a 12 month plan."

See Adobe? How come Phase One gets it right with their new Capture One Pro 8, and you don't at 9,99 USD / 12,29 EUR for your yearly CC Photography plan?

I think he means the exchange rate?

Sad there is no 5R/T any more. Small as is comfortable to hold yet with two control dials.

Page 9 with the pop up flash. Why use the camera upside down? :)
The other way up and you light from the top and your shadows go downwards. Because we are used to seeing people lit by the Sun the shot looks odd as you have it.

bodensee: Surely the pricing is wrong? Can someone from Canon comment. I won't be buying one at the rip-off British price. I see as well I'm not the only one having an issue with the pricing.

Yep, crazy price. At the US price I might have bought one.

In reply to:

avicenanw: My guess coming up next is the pricier Alpha a7000 (which replaces the Nex7). It will have things purposely missing from the a6000, like level indicator, higher resolution EVF, stereo mic. jack, touch screen, etc.

But the 28-70FE on the A6000 gives you a completely different field of view to the 18-55 on the A6000

The 55-135 is exactly what I'd like for the sony e mount. Right size and speed.
Pricing is nothing to do with how well they are built. I saw a blad USB cable for £80.

Was in the market for this but won't buy anything with a US to UK exchange rate that weak. Convert to UK pounds and add 20% VAT and you get £680. Have to see where street prices end up.

HaroldC3: This might be a good alternative to the Sony 10-18mm for NEX users. Not only that but very good for astrophotography!

There are other samyang lenses that have excellent coma control.

As a good will gesture and in consideration for...
1) those that were not expecting to be buying into a dead end product and have spent a lot of money on upgrades on the understanding that there would be a future CS7, 8, 9
2) those that were misled by the "only upgrade on version ahead" policy that was introduced, then modified then made redundant. would be nice if we could get the full ACR8 versions in CS6. Call it a parting gift so those that feel cheated get that as a sweetner. Maybe then we will see if you hold you promise about Lightroom and buy into that down the road when it isn't quite so slow compared to ACR.
As it is I won't buy anything by Adobe.
