On article Benchmark Performance: Nikon D810 review (1980 comments in total)
In reply to:

Revup: Why do they say 'Group Area AF introduced in the D4S' I had group (Dynamic) Area AF on the D200! I missed it on the D700, now its back on my D810 and it doesn't seem to be much different in set up to the D200. What I mean is, this is not a NEW idea at all on a Nikon, yet every review seems to suggest it is! Its at least 10 years old, albeit it has skipped a few models!

They're not quite the same thing.

Dynamic area AF focusing on a single point but will consider the neighbouring points if the subject falls off the specified point for a while.

Group area AF uses a cluster of focus points (not just one) to specify the subject. I believe the idea is that you use it when it's so difficult to keep a single point on your subject that Dynamic risks drifting off and focusing on the background (which it will do after the single point has been off the subject for too long).

It's a subtle distinction but it is new.

Yxa: I thought that the sensor had 20.9 mp not 20.7

5568 x 3712 maximum resolution. That's 20.7 MP.

I'll look back at our existing stories and try to hammer some consistency into this.

EthanX: The 7200 has a flash - so why isn't the cell in the comparison green?

The 7200 is 24MP, the 500 is 20. Again, no green color.
The 7200 is a lot lighter. 85 grams lighter.

Plus, I believe the price row is missing... :)

So many opportunities missed to show the weaker sides of this camera compared to its cheaper older brother. Why?

...Ah, and you don't have to spend your hard earned money on features you won't really be using (200 high-end raw files in one burst? that's 20 seconds, what are we trying to capture, a passing train?).

Nevertheless, it's got some nice strengths. 4K video, tilting touchscreen (although it diesn't flip sideways), bluetooth. not bad.

This method of which box to highlight has been used pretty consistently for the whole time I've worked here. I haven't done anything differently for this review or to intentionally benefit one camera.

Yukon Ranger: Let the Dpreview/Nikon/bhphoto viral marketing scam begin!

Don't be fooled.

The d7200 will give u sharper cleaner images up to 3200 ISO, with 15% more reach at less than half the price.

Every shot taken on d7200 picks up 3 mp of data the d500 can't even see.

100 bucks says 10 replies to this comment, arguing how wrong I am. But the math don't lie folks, and neither do the samples.

Don't be fooled.

I don't think we've ever been accused of viral marketing before.

The D7200 is a lovely camera. My original draft of my first impressions said:

*Nikon’s strategy of pushing a lot of the D300S’ features into a small, more affordable camera, rather than providing a like-for-like replacement put a lot of capability into the hands of a lot of people but it also left another group of users unsatisfied.*

For a lot of people, the D7200 is more camera than has been available at that price. However, there are some users who want/appreciate/need the extra capabilities that the D500 offers. Those differences aren't about image quality, they're about performance and dependability.

Peter62: The D500 has no chance against the Fuji X-E2 !

Just try the following, it's the best way to evaluate sensors:

Use DPREVIEWs phantastic Image Comparison Tool.
Switch to LOW LIGHT.
Set ISO 12800 (i.e.).
Compare Fuji X-E2 and Nikon D500.
Buy the Fuji. Forget the overpriced D500.

Jochenls - Fujifilm's JPEGs do tend to be between 1/3 and 2/3EV darker than you might usually expect but our Raw tests are shot at the same exposure settings, then brightened to a common luminance value, so you're looking at an apples-to-apples comparison.

obscurelines: Wow, Fuji forgot to pay their protection money this week.

Lovely bit of paranoia but, given the X-T10 and X-E2S are in the category below and the X-T1 in the category above, I'm not sure which model you think we should have included here.

weathersealed: Here are the quotes from DPR themselves on the Sony A6300 {The A6300 image quality is excellent-as good as we have seen from an APS-C camera of any type from any manufacturer} {As a stills camera the Sony faces the likes of Nikon's D7200....but it is the strongest all- arounder} SO which one should I buy? the one I like the best perhaps.

If you have any interest in video at all, the a6300 is the better bet.

If you don't, and you're not concerned about size/weight, then the D7200 is probably the nicer camera to shoot with.

Specs are marked green when that camera is either alone in having something or has the best of the three. If two products share a spec then it's considered the baseline (so remains grey). If the third one omits that feature, then the camera that's lacking is marked in red.

We don't mark the weight, size or, generally, the pixel counts as good or bad, since they all depend on your preferences and usage.

Scottelly: Really, this is sad. Sony already has a camera capable of faster shooting and higher resolution (24 MP with no AA filter). It has a tilt screen, like this D500, and it does 4K video too, but it weighs less than this D500, and it's only half the price! How great is THAT? Nikon REALLY needs to catch up to Sony!

http://www.bhphotovideo.com/c/product/1222744-REG/sony_ilce6300_b_alpha_a63000_mirrorless_digital.html

I think the ONLY thing Nikon has going for them now is that their weather seals and deep raw shooting buffer might attract a few hard-core professionals. The rest will go to Sony. Sony needs only to create a line of A9 and A9000 series cameras with weather seals, and they'll have the whole market wrapped up.

There's the small matter of pro-sports-capable AF.

The a6300 is really good for a consumer-level camera but the D500 is in a different class, both literally and metaphorically.

I'm not going to start counting pixels you don't get to use.

maico: I'd be interested to know what Richard Butler thinks of this Youtube video ?
It seems to be specifically stating a bigger sensor area does not gather more total light...
https://www.youtube.com/watch?v=qnAN0nWef-I

Shoot similar pictures (same field of view from the same position) Use the same shutter speed and f-number and ISO.

View the images at the same size (on screen or on paper).

Any part of the image you look at will look cleaner on the larger sensor image (assuming the two cameras are of similar age and technology).

Both of the cameras will have received the same exposure (same light per unit area), but the larger format one will be cleaner *when viewed at the same output size*.

The number of pixels and the microlens design will make some difference but that difference will be peanuts compared to any significant difference in sensor size.

I think that most people shooting a scene would choose the lens that gave them the field of view they wanted from the position they can shoot with. (Which means using equivalent focal lengths).

In other words, I'm not comparing case 1 and 3 in the diagram at the top of the page (which would give different images if shot from the same position). I'm comparing cases 3 and 4.

Secondly, I'm not suggesting viewing images at 1:1 scale or in proportion to the size they were captured: I'm suggesting scaling them to the same size, just as you would if you decided to make a print.

In other words, I'm taking the quality of the whole image perspective, not of a square micron (or any other size) of a sensor's capture.

As I say, exposure is a per-unit-area way of looking at light. That's a great way of building a system that's format independent, but a strange way of looking at the end result.

While much of what he says is correct, the conclusion he draws is interesting, to say the least.

To be clear, we do not ever claim that large sensors affect exposure (which is a per-unit-area measurement and hence, *by design* format neutral). We say that they have more area committed to the image and hence capture more total light. This is a key distinction.

This starts to show the different fundamental assumptions between the way the two of us are looking at the problem.

The video says that sensor size has no impact on exposure, only on field-of-view. He also talks about the photosite size making noise better. Both of these are true but assume the following:

1) That you would shoot different formats with the same lens and just accept that one of them is more cropped in.

2) That you would only examine the results at 1:1 pixel level.

By comparison, all of the articles we've posted have different assumptions. (Cont...)

On article What is equivalence and why should I care? (2177 comments in total)
In reply to:

Branta: Thanks for this article. I now understand equivalence better - and why I DON'T care !
I found this article because I was confused by the reference to equivalent apertures in the review of the Panasonic/Leica 100-400 lens.
On page 1 you say "We don't expect you to take our word for this" and I didn't, I used DOFmaster to work out some examples, being careful that CofC was scaled in exactly the same way as the crop factor. And sure enough I now convinced myself that I need half the F number on a MFT lens to get an equivalent DOF to full frame.
But actually my main loves are landscapes that are sharp from foreground detail to horizon, and wildlife through a telephoto lens. With a typical bird photo I have no difficulty getting foliage behind the bird out of focus, I really want to be sure that the tip of the beak to the tip of the tail are in focus. So I'm grateful that in both these cases "equivalence" works in favour of the smaller sensor.

Absolutely. Equivalence doesn't tell you what the right answer is for you, it's simply a tool that lets you evaluate the different balances between size/image quality potential and price that are available.

I wouldn't expect many people to try to use it when actually shooting.

ChrisH37: I appreciate it doesn't really matter in the grand scheme of things, but why semi-pro over pro? I know quite a few working pros still using battered D300S' and as far as I'm aware it qualifies as a professional body for NPS purposes.

It seems only the sensor size is the 'issue', but that's largely irrelevant for the intended users of this camera, in fact many will be buying it because it has a 'smaller' sensor.

Think of it as '(Semi) Pro.' Unlike the D5, we believe there'll be plenty of committed amateurs and students also buying this camera. So yes, I totally agree that it'll be used by pros: we categorise it as semi-pro because it won't *solely* be used by pros.

Electricturd: The chart comparing the 3 different cameras states that the D7200 is Carbon Composite only. Thats wrong, its external body has the same materials as the D500 (Mag top and back, Carbon front)

That's true. I've corrected it.

Spunky_me: Question: how did you compost the skateboard jumping shot with multiple shots?

I used Photoshop's photomerge feature to align, warp and combine the image, then manually edited the layer masks to bring back in the overlapping skater images that the software had removed.

MattiD80: I want to see comparison in shutter shake between sony A7RII and D810 (not A7R1). Reading between the lines in both reviews, the A7R2 sounds much better in this respect, (one of reasons i'm leaning towards sony for next camera). Shutter shake is one of the biggest causes for soft images on my d800, it's one of the things I want most fixed (more so then extra DR or focus speed).

Rishi is talking about electronic *first curtain* mode (not full electronic shutter), which still uses a mechanical shutter to end the exposure, avoiding rolling shutter and which can still be used in 14-bit mode.

Pikme: These round ups are showing what rational people already know: brand name digital cameras are all good these days, just buy one and stop agonizing over which one is 'best'.

Also, just because they're all *good* doesn't mean they'll be a good fit for *your* needs.

There are still significant differences between each model's strengths and weaknesses. It very much matters which is [best *for you*](http://www.dpreview.com/opinion/0450858820/).

Nick Carrigan: What does this CON statement mean: Lack of external charger makes it hard to keep a spare battery charged???

There are plenty of Sony external battery chargers for the NP-FW50 battery. The Sony BC-VW1 is the best charger and works great. Charges the NP-FW50 battery in 1.5 hours.

That's a good suggestion. I've amended the wording to make it clearer.
