On Sony: An eye on focus article (758 comments in total)

PerL: So would this system enable Sony cameras to shot a low light indoor sports game with a 200 2.0 lens wide open at 10 fps with a higher number of keepers than a Canon 1Dx or a Nikon D4s, or is it just nerd stuff?

@ttran88
I think you are to emotionally invested. It is just about cameras.

@Celsus,
OK "nerd stuff" was a little harsh, but on average it seems like there is an article a week about some new fantastic AF-technology from Fuji, Sony, Panasonic, Olympus etc to overcome the problems with sensor based AF-C. There has been so much hype so I have become a little cynical.

@all,
The tone of the article is that this is a game changer, so I was asking if it truly is a game changer – will it be a reason for those depending on AF, like sports pros, to switch? Apparently not.

Well, I have to interpret the answers so far that there is no improvement for those really needing AF-performance. So I must conclude it is mostly nerd stuff.

@Celsus
I am talking about those who really needs high performance AF. Working professionals shooting sports and action and news in any light. For the rest of us the question is mostly academical. Unless of course you have a lot of AF-problems, but I really doubt that is a great worry for the majority, at least those using DSLRs. Early mirrorless with slow CDAF could be another story. But even those are better now, I understand.

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.

In reply to:

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)
