PerL: There seems to be a lot of excitement on the mirrorless forums about red dot sights, bypassing the EVF altogether for tracking action. That tells me that EVFs still lags OVFs in speed, by an amount enough to be an issue.

@Fri13
Blackout time is longer than with mirror flap on a high end DSLR.
The lag of EVFs is influenced by the processing going on.
About EVF lag:
From Imaging Resource shooters report of Samsung NX1:
"in sports photography, where a hundredth of a second can make a difference, that short delay can cause you to completely lose track of the action -- by the time you're done firing off your burst, your subject matter might be completely out of frame, as was the case for me a few times in both hockey and volleyball.

If anything about the camera turned me off on using this as my full-time sports camera, this is it. I tried varying the burst rate between the full 15fps down to 8fps in Continuous High mode, and while there's some improvement in this EVF "lag" at a slower burst rate, it wasn't a significant improvement, I found. It's but one major flaw, but in the demanding world of sports photography, it's a big one that can make or break whether you get the shot you need."

@Eric Nepean
The quote is from the m43 forum where they discussed how a red dot sight was a way to get around the problems with long blackouts at medium fps and AF-C or no live view when shooting at full fps and AF-C. So I concluded in my first comment here that EVFs lags OVFs in this regard.
Yes, I understand the principle of the wider FOV of red dot sights, but that is another question.

@all:
So how should one interpret this quote:
"Well, as long as your subjectsare movubng relatively consistently in one directions, the dot sight arguably won't give you any advantage. Other than with my E-M1 that is hampered either by blackout phases (C-AF up to 6.5 FPS) or lack of liveview (C-AF up to 10 FPS)."

@Thorgrem,
I am sure it has to do with EVF-problems, judging by the comments about it on the forums.

PerL: Why not mention the OVF as a great pro for action shooting - totally stable, lag free, no jerking, no distractions by limited DR or exposure changes, easy on the eyes for long shooting sessions. Always on for fast reaction to sudden photo opportunities. This is a major difference and a main reason for choosing a D7200 over mirrorless alternatives.

Azurael,
The reviewer compares several aspects vs mirrorless cameras. But not this main point. I am not sure everyone is aware why many high end users prefers OVFs for some types of demanding shooting. Never mind if it is mentioned as a "pro" (although it is for action shooting) but a least a discussion about it should have a place in the review.

What I miss in the review:
1. Reasons for choosing an OVF DSLR (I discussed it in an earlier comment)
2. System. Surely the largest lens and body (FF-cameras with the same mount) system together with Canon is a plus point?
Many mentioned the Samsung NX1 which scores higher. What about the Samsung system vs the Nikon system?
This is a camera with a potential as prosumer action/wildlife camera with options in high end fast lenses that only Canon can match. No, its not a compact travel camera, or a video optimized camera and it is heavier to carry than lighter cameras. But it has other strengths, I am not sure the review points them out properly.

@Azurael
I think the advantages of OVFs should be mentioned or at least be discussed in the review, since those are key reasons why many would choose a D7200 - which after all is the camera this review is about.

PerL: But, but... how come the camera need improvement in AF? They already claimed they had the worlds fastest and best AF when it was introduced?

http://www.dpreview.com/forums/post/53100738

Is it possible that claims about AF generally has a lot of hype involved and that one should be skeptical until it is proven in the field?

@Gediminas
yes, I was being ironical. Claims of the world fastest or best AF has been so common that many camera companies has lost all credibility in this regard.
And the point is not that they try to improve, the point is that they promise to much and deliver to little.

In reply to:

fmian: Still not getting Nikon's control layout decisions.
3x Buttons within toggle switches (one of them unlabelled)
2x info buttons (one marked 'i' and the other 'info') that do different things.
2x buttons with 3 labels/functions designated to them
2x AF/MF switches on the system (one on body one on lens)
And long scrolling menu pages...

Surely this is difficult for beginners to learn with??

How do you set an Olympus OM-D to continuous AF, fastest fps? I have never figured that out when I have played with those camera bodies in a store. To me the menu system is totally confusing.

PerL: As a side note...
Interesting to see that despite over seven years of development the latest most high tech APS-C sensor still can't match the high ISO/low-light sports shooting capability of a FF Nikon D3, introduced in August 2007. (DxO ISO 2303 vs 1363 on the Samsung).

(No text. I changed my mind)

A few thoughts on battery life and action/sports shooting. Battery life rated 500 images - that is 33 seconds of shooting bursts at 15 fps. How does the battery cope with 90 minutes EVF-on? (The length of a 2x45 min soccer game). How is it affected by cold temperatures?

PenPen: I have a question for camera experts like you. I currently have an old Canon 550D since a few years and want to buy a new camera, a bit more pro. I was expecting a lot from 7d Mark II but was disapointed, as it's not a camera for me. I'm more interested in landscapes and street photography than wildlife or sport. And I'm not interested in video or be able to shoot 15 images per second.
And so now I'm thinking of leaving Canon and I'm hesitating between Samsung NX1 and Nikon D750. The NX1 seems more interesting in terms of modern features, but in terms of image quality, is it equivalent to D750? Can a very good APS-C mirrorless camera compete with a full frame camera in terms of image quality?
Thanks

No, the FF look is real, just as the MF look is real and m43 looks different than 1". Or do you think they all look exactly the same?

So I looked around and read some other tests, mainly regarding the action shooting and sports capabilities. I suggest reading Shooters Report Part I on Imaging Resources Samsung NX1 Review for an understanding why DSLRs with OVFs and traditional PDAF still is the best choice in this area, despite this very good effort from Samsung.

As for the innovative Samsung BSI sensor (83 at DxOMark) - DxOMark just published the numbers for Nikon D7200 - a new class leader in APS-C (87)

vermaden: DSLRs are like Hard Disks now, technology innovation is saturated, not much more can be done to make them better.

... on the other hand Mirrorless cameras are like Solid State Drives (SSD), there is a lot more to achieve ... in software ... in firmware ... in hardware ... everywhere.

Do they (mirrorless) take better photos?

Besides the support organization a "pro" camera is one that can take photos for publications in the widest range of conditions with no excuses, at least it must be able to shoot what the competition can shoot. That is why a camera that can't shot low light as well is a non-starter.
Is the pro cameras insignificant in economic terms? They might be because the whole profession is going under. But now they are important - it is easy to see when you look at the resources Nikon and Canon invests in this segment. As a percentage of cameras sold they may be small, but the prices are much higher and the buyers invest much more in lenses.

@tedolf. Absolutly. this is probably a very good camera for amateurs and maybe some professionals that has an interest in hybrid/video shooting.
