The Nikon D810 is better than the Canon 5DIII in every respect. 

That's the second time you've made that ridiculous claim.  Let's start with some really, really simple questions.

  • How is the D810's 5 frames per second better than the 5DIII's 6 frames per second?

Oh, and I hope your answer to that first point won't foolishly invoke the higher frame rate in DX mode, unless you're prepared to also explain how using only 43% of the sensor area is better than using the whole thing.

[...the new D4s/D810 AF is a preetty noticeable improvement and has definitely narrowed the gap as long as you can keep the subject in the center of the frame.

Well, as I stated, I wanted to start simple.

But...you make a good point.  As we all know, putting the subject in the center of the frame always makes for the strongest, most compelling images.

I gotta jump in here.  Your request would be completely pointless.  I have to ask:
-What is the purpose for you wanting a handheld test?

It's always nice to meet people for whom the theoretical best possible results are practically, routinely achieved.  From your question, I assume 100% of your shots are taken from the sturdiest possible tripod. 

My auto manufacturer put a sticker on my car that said it achieves 26 mpg highway.  Our road trip average is closer to 20 mpg.  Our other car is rated for 36 mpg highway, and delivers ~34 mpg.  Same EPA-mandated rating system, same driver, both cars maintained per recommendations, etc.   Yet the real-world vs. spec'd performance differential is different.

The issue is the claim that smaller pixels deliver higher resolution that is predicted by the difference in pixel sizes.  The point is that in real world use, smaller pixels don't deliver as differentially higher resolution as pixel size alone would predict.

  • How is the D810's 5 frames per second better than the 5DIII's 6 frames per second?
  • How are the D810's 15 cross-type AF points better than the 5DIII's 41 cross-type AF points?
  • How are the D810's zero f/2.8-sensitive AF points better than the 5DIII's five f/2.8-sensitive AF points?

I look forward to your explanations...you can back up your claim, right??

At birding spots I frequent, I see lots of big black lenses, even more big white ones with red rings, and one with a green ring.  The guy using the 400 DO loves it...because of the combination of long focal length, fast aperture (for 400mm), and a size/weight that his arthritic hands can manage.  For him, the last is the most important criterion, aperture second.  He has a 100-400L too, and uses that during flare ups – he feels the main advantage of the 400/4 is the aperture, and that the IQ isn't much better with the DO.  Of course, that's totally anecdotal.

Still, it will be interesting to see what Canon can do with a MkII version.

50 MP, 16 stops of DR.  Canon must respond to that!!

EOS Bodies / Re: Do Sensors Make the Camera?

Chuck, if you can't see that the middle one should be the best, that's just sad.  I say 'should be' only because it's hopelessly marred by the horrible noise and banding where you lifted the shadows.  If only you had shot it with a modern Exmor sensor instead of a Canon sensor made with antiquated technology, you could have produced a noise-free image with the perfectly flat lighting that's the hallmark of good photography.

I have had the same tripod ring for some time, no issues.

Photography Technique / Re: Back-button focus?
« on: August 29, 2014, 10:20:39 AM »
I use BBF, in One Shot for still subjects and in Servo for moving subjects (different C# settings). 

The only significant drawback is if you hand the camera to someone so you can be in a picture, they'll most likely expect a shutter half-press to focus.  Not an option for me, but 'green square' mode puts focus back on the shutter button.

Software & Accessories / Re: Kirk BH-1 or RRS BH-55 Ballhead?
« on: August 29, 2014, 10:07:40 AM »
Maybe I should just stick to Kirk then and get the BH-1 if both ballheads are close in performance.

I have the RRS BH-55 LR, a friend has the Kirk BH-1.  They're both excellent and so close in performance that I don't think you can go wrong either way.  The RRS is ~1" shorter.  Personally, I really like the RRS lever clamps, too.

Put another way, it took Nikon two generations to come up with a camera that approaches the 5DIII in overall utility...and I bet the 5DIII outsells the D810 just as it did the D800/E.

Same thing one step up – it took Nikon until the D4s to approach the 1D X.
Errrrrrr I don't think we are talking sales figures here but camera technology.  Precisely where does the D810 not exceed a Canon 5DIII? Nikon D810 exceeds the 5DIII in any reasonable comparison.  In quality of the sensor it absolutely trounces the Canon.  lets not distract the conversation with lens line or spots on the D600 sensor and stick to the comparison between the 5DIII and the D810 bodies.  The 5DIII "approaches" the D810 in some respects...but exceeds it in none.  BTW I own and love the 5DIII but it is outclassed by the newer D810.  Yes, Canon is 2 generations behind, at least on sensors and it doesn't look like that is going to change anytime soon

I see you also believe that the only important part of the camera is the sensor. 

Ooooh, look at that amazing bird-in-flight shot from the D810...incredible resolution, really wide dynamic range.  Sure, it's a bit blurry because the AF couldn't track the subject well enough...and just a little off optimal wing position where maybe a 20% faster frame rate would have helped...but just look at the DR and all those MP.   ::)  Camera ≠ sensor.

As stated earlier, the 5DIII has a faster frame rate and a better AF system, to name two camera technologies where it is superior to the D810.  The D810 has better low ISO DR, great if you need it.  It has more MP, although with many lenses that doesn't translate to better resolution (and when it does, the difference is much less than the MP differential would suggest).  You may view lenses as a 'distraction', but unless you drill a pinhole in your body cap, lenses are necessary.

810 doesn't just approach the 5d3, in tech, it pulls out and passes it and flips the bird at it on the way by.
  AF system...5DIII > D810.

Everything I have read from people who have tested says the opposite - what do you build this claim on?

I base it on a thorough understanding of the specifications of both AF systems.   Oh, and actually trying out both cameras one right after the other.  Have you done that?  Or are you building your counter claim based solely on reading stuff and watching YouTube videos on the Internet?

Perhaps you believe everything on the Internet is authoritative?  Take Tony Northrup's YouTube "review"…in his "sports" test, which consisted of a subject walking sedately toward him, he reported a keeper percentage in the low 60s from the 5DIII.  What a joke, but I suspect you believed every word.

Yes, we all know you think "camera" = "sensor".   Frame rate...5DIII > D810.  AF system...5DIII > D810.
