HowaboutRAW: Good for Sony, now reconsider compressed raws in general.
Both of you: show us one picture taken by yourselves where cRAW is a problem.
GoneMirrorless: A 1 inch sensor with an F/5.6 lens and no RAW output means there is no way possible that this is a serious or even 'amateur' stills camera.
Does it come with a flash to overcome those flaws?
brendon1000: A pretty good review and I agree that I feel the weight of the A7 II is a bit heavy. Was pretty happy with the weight of my A7 which I feel is ideal for a mirrorless camera.
Even I am clueless why Sony went from those lovely dials on the A7 to the crappy ones on the A7 II. Why Sony why ????
One area I don't agree on is the high ISO performance. The low pass filter on the A7 II is pretty weak and your own comparison tool shows that at high ISO the A7 II files are sharper than the D750 and I even downloaded both files to compare and honestly its a tie for me upto ISO 12800.
IBIS was turned ON in the A7II shot, as the EXIF of DSC00499.ARW clearly proves. This is against Sony's recommendation when shooting on a tripod and has been proven to decrease resolution.
mick232: As for the RAW compression issue - the same compression algorithm is used in the A99 and other Sony cameras such as the RX1. Not the dpreview review of the A99 nor any other review I am aware of has found this to be an issue when they reviewed the A99.
Now that there is a hype around the issue all over, it suddenly is a big deal even in reviews. Doesn't make a lot of sense to me.
The review complains about compressed RAW and the fact you can't change it to uncompressed.
At the same time, the studio test scene (DSC00478.ARW) has been shot with IBIS turned ON on a tripod, against Sony's recommendation. This has been proven to result in less than optimal image quality.
So I am left wondering why it is a problem that we get less than optimal image quality and we can't do anything about it due to technical limitations, and why then it is not a problem to get less than optimal image quality when we actually could have done something against it?
The A7S review points out the benefits of compression (smaller files, higher write speed). That part was unfortunately omitted in the A7II review.
The review also fails to clearly point out that the issue is not a general problem with A7II RAW files but affects a diminishingly small subset of all RAW images in extreme cases. ("Unfortunately, one persistent issue with Sony Raw files might limit the usability of Raw files, particularly when pushed.")
Millions of images have been taken with Sony cameras for years without anybody noticing the issue, including reviewers. It was first mentioned in 2014. Now it is presented as a problem that everybody knew about for ages ("Raw compression issues we've seen from lossy compression in many Sony cameras").
Much of the excitement about this issue is probably not even due to the practical implications of it but the contradiction of marketing claims ("14 bit RAW") and technical reality, which one could rightfully criticize.

DenisBBergeron: How Sony Camera sensor can be worst than Nikon or Canon sensors ? Sony make sensors for both !
@Rishi Sanyal: if the isue shows up fairly frequently as you say, then why wasn't the issue noticed in the DPR A99 review? It uses the same cRAW compression algorithm as the A7 series.
In fact, 14-bit RAW is praised as an advantage of the A99 in that review. My theory is: there was no hype around this so-called issue back then, therefore nobody cared about it.
It doesn't get any truer the more often that myth is repeated. Lossy compression may cause slight degradation in extreme cases, but gets blown way out or proportion in the review and these comments.
The different scores in image quality compared to D750 seems to be blown way out of proportion by DPR. Besides, the 6D has higher scores than the A7II which totally contradicts what the review text says.
Eleson: "The taller, USB 3.0 port means you can get data off the camera faster but it leaves no room for the headphone socket featured on the EOS 5D III."
Are you implying that that the lack of headphones jack is due to lack of real estate? Why not be honest and say that is was left of for market positioning?
SmilerGrogan: Now that this camera has such a sophisticated metering system why can't Canon engineers change the sensitivity of individual areas of the sensor in response to the light on the scene? In other words, why can't they raise the ISO in the shadowy areas of the scene, lower it for the highlights. That would get rid of the need for HDR and make all the high-dynamic range people happy.
The metering system tries to make each area of the image 18% grey. If you adjust sensitivity in different parts of the image according to their brightness, all you'd get is a 18% grey image.
LMCasey: It really is too bad that Canon did not take the opportunity to also improve DR of their sensor. I guess this is a stopgap.
They confused DR and noise - instead of lower noise and higher DR they created it the other way round.
Rick Knepper: It was improved, relatively speaking. A sensor with twice the pixels has the same DR as the 5D3 = improved.
No doubt the technology has improved - Canon is now capable to cut 7D sensors the right way and glue them together to fill a full frame area.
Dr. Leonard: Pixel density the same as the 7D so expect noise at high (1600) ISO. Not terrible if one uses noise reduction but it is a truism that noise degrades images and noise reduction gives you degraded images with less noise. The new (and more expensive) Pentax 645Z has about the same MP but with a larger sensor. Samples I've seen are impressive with their low noise.
Canon's sensor technology has vastly improved.... Canon is now able to cut 7D sensors and glue them together in exactly the right way to fill a full frame area.
Bhima78: Mind boggled that the A7 II wins over the D750. Even though I have fully converted to mirrorless, if I had to buy a high end ILC, i'd get the one that actually has an amazing native lens library. Taken as a system, the D750 is leagues better.
It is "best product of 2014" not "what is your favorite system".
mpgxsvcd: The point of this lens is that it is supposed to be a high quality lens without a high quality price. There is no way of knowing if it really is a high quality lens yet. However, its price does look attractive. For movie shooters manual control is all they need.
@helltormentor I doubt the Canon is better than the Sony Zeiss 135/1.8
steelhead3: The lens is G rated...higher than the Zeisses.
Sony usually uses a G branding for zooms and the Zeiss branding for primes. Look at their latest investor relations presentation, it is explained there. Both are high quality brandings, and you can't make assumptions about one or the other being of higher quality.
AngryCorgi: Wait...I thought they closed their studio! Someone step on this slug and put it out of it's misery. Hassleblad has become a total joke.
Yes the design studio is closed - they found that asking the cleaning lady to design the camera will give them exactly the same result as asking the design studio. We may still see more of this stuff!
jtan163: Oly and Sony's partner ship pays off for Sony.This will be a total monster for adapting lenses.When the A7sII comes out it will be an even more incredible video camera.
@mister_roboto: you can probably also tell us that an Airbus is a Boeing design, right? They basically look the same after all.
ZoranHR: Big attention this camera gets. I would like Sony system continue to improve,there is a space. So far I m not interested. Battery life is poor. Also I would like to have an oportunity and see how it feels in hand with some proper glass. I m afraid FF lenses are heavy and whole package is akward to hold. But that I would have to see.
So you are telling us you do not buy an otherwise great camera because of what you call poor battery life? Seriously? You do know that batteries are exchangeable and cost next to nothing, right?
