Marcelobtp: I wonder why battery life still is not considered in the scores...

Maybe a good bias for the mirrorless system overall?

In reply to:

deep7: I know what you people are saying about the RAW conversions but it's a bit strange.
1. Any camera benefits from RAW conversion (except maybe some Fujis).
2. The Sony jpegs have done a much better job controlling noise. Yuk to noise!
3. Using auto white balance in mixed/artificial lighting isn't "professional". If you are doing this for a living, you will make the tweaks before you shoot. Even so, the Sony jpegs are far from appalling and easy to tweak if you need to.
4. Highlight recovery looks really good! I wonder if you can set the camera up to better control those pre-capture, as you can with Olympus?

"professional" compromise, always comes to help the ufanist fanboys.

In reply to:

Sony A6 Series Shooter: Thank you very much for posting these "Raw versus JPEG" comparisons.

As I've suggested elsewhere, the A9 is shaping up to be a great stride in the development of Sony's camera line...

That said, your comparisons suggest that Sony's software engineers still have their work cut out for them, insofar as the camera's JPEG output is concerned.

BTW, as out-of-keeping with the camera's character as astrophotography might seem, does DPR plan to run some tests of the A9 to see whether or not it, too, is afflicted with the "star eater" issue? This is something that many astrophotographers have been complaining of vis-a-vis the A7 series (those, that is, who have updated their cameras with the latest firmware upgrades)?

Ohhh, My pop corn is ready already.

Marcelobtp: This will be a DSLR killer when the 20 fps being 14 bit true raw,
Sony only offers 20 fps on 12bit compressed.
Even the uncompressed 14 bit files are compressed as clearly proved on the star trail cleaner after the 3.2s of exposure.
Sony colors, white balance, all needs much improvement.
Their lenses are not as good as they sell, with pre baked automatic profiles that you can only dial up and down, never off.
Anyway, PROs knows what they want and why they want.

Thats why the world is full of fools...

They do overheat, they just do it less frenquently, or sony let the temp limit higher...

OVERHEATING FREE? THAT WAS MISSING RIGHT THERE...
Now Sony just need to let you use TRUE RAW images, and up their image quality.
Big supporter of Sony in the beggining, not anymore, this camera should have been launched earlier.

In reply to:

Infared: WOW!....GREAT article!..
I had already come to a lot of those conclusions...thanks DPR for confirming them.

I am really looking forward to this:
"But remember you can emulate much of that color science in Raw converters with proper profiles (we're looking into a separate article on this)"
That is an article that I want to read!!!

Exactly!

In reply to:

wjkotze: There are thousands of high-end professional photographers in the world that uses PhaseOne and Hasselblad systems that costs many times more than the Fuji but using the same chip. Based on your analysis we should assume that these people are ignorant incompetent fools with to much money. The reality however is that these people work for very demanding customers and make there decisions based on a very critical analysis of image quality. Some of the key attributes they are looking for is neutrality across the tonal range as well as tonal transitions in deep shadows and upper highlights. The extra DR and pixels are welcome benefits but are secondary to the overall aesthetic appeal of the files. If you and/or your customer cannot see the diiference then obviously FF would be the obvious choice.

This!

Marcelobtp: Sony is doing an admirable job iluding its costumers to pay premium for the same lens, just with little corrections mostly on software...
Just sad, too many sheeps

Sadly it does not make me smart, just show whats happening with the world we live in a bunch of Zombies...

In reply to:

justmeMN: If memory serves, Tony Northrup contends that FF lenses produce inferior results when attached to an APS-C camera. Lenses specifically designed for (only) APS-C are said to produce better results.

It depends, generaly is the oposite.
An apsc lens will generaly have more vignetting and will not be as sharp in the corners.

Fuji uses sony sensors thats why...

Marcelobtp: Nikon to me is almost dead.

I don't want to sound arrogant, but i completely disagree with you, dslrs are the past, theres no way back, it will be used on niche events like film photography is used today, like a hipster thing. Film still today has better colors in my opinion, but theres no coming back, dslrs ovf has no lag, but they are faded to sports only until the evf tech be so good that we will not be able to perceive the diference.

Marcelobtp: Hoped to see a wider dynamic range here.

Being a Sony sensor much bigger than the FF i would hope 1 to 2 stops more over the a7r2. Comparing to Canon's is not a big deal.
