A recent Tony and Chelsea Northrup review compares both cameras using identical Tamron lens.
Stop right here. Tamrom has a lens that can resolve 36MP with no AA filter? I'm already laughing on the floor.
To them it suggests a clear winner.
We all know that photography is much more than the gear but hey, this is a Canon gear forum. With yet no new gear from Canon that responds to what Nikon is delivering with the D810, there must be those who are considering the option of acquiring the D810 along with the required lens. (If you purchase some Sigma lens, you can even have the mount changed.)
Compelling features about the D810 compared to 5D Mk III
- low ISO 64
Versus 100? Wow, I'd switch in a minute. That's going to revolutionize my photography!
You do know that sometimes artificially low ISO's have lower picture quality that the native low ISO, right, and their primary purpose is to avoid the use of a ND filter?
- much better DR
- much better noise at low ISO
The question is, how much is this a problem in your photography? I think the Nikon is better, but is the Canon a problem?
20%? Not 21.5667%! People can't even agree with accurate AF means. There is no such thing as "20% more accurate" AF. Tracking? Static? Within the DOF? Within the sensor resolution? Which focus points.
The mind boggles at this statement.
- auto face detection exposure adjustment
Fail. They should have had dog detection. And my cat still feels left out. I totally agree with you. Any pro photographer need face detection, smile detection, and built in Instagram filters.
- far better detail due to the 36 MP sensor
None of this may be important to those casual shooters who don't care about such features but it must be causing professionals who strive for near absolute technical perfection (using 35mm equivalent FF digital sensors) to consider it. If the camera significantly reduces workflow-time and reliably produces a consistently superior image product, there must be some temptation by such folks to seriously consider it.
Pro's need face detection? Then buy a cell phone . . .
If you can't tell the different with a 12X18 print, and that's the largest you print, it is of zero importance.
It's likely not a perfect camera as some suggest the build quality is not as good as previous model but time is money and a faster more streamlined workflow quickly justifies the acquisition.
Face detection stream lines your workflow? What, you do noise reduction at ISO 100 with your Canon and you wouldn't with the Nikon?
Also, there be a whole lot of folks feeling rather "burned" right about now. This modern day disposable business philosophy that ignores the current model defects and simply produces an "improved" model in a two year cycle, will leave a bad taste in those who cannot afford to simply shrug it off. At least with the Canon models, significant time has elapsed to achieve a ROI that helps justify the equipment upgrades.
Let me get this straight. You are a pro? You run a business? You have a ROI? Not to be mean, but I'm not seeing in that in your photos. You got a "pro" website to show us? What are your rates?
If it works as tool, it works. The 5dIII is the 1st camera where I feel no need to upgrade.
What I'm seeing is a bad gas of GAS and product envy. Not any compelling need.
If considering tossing the 5D MK III's into the corner in favor of a D810, what are the main reasons why you would? What are the absolute minimum features you would need in a replacement camera from Canon?
None. It took Nikon how many generations to make the 810? From oil spots to AF focus problems in multiple models. What's going to go wrong with the 810 that we don't know about yet?
Don't get me wrong. the 810 is probably a very nice camera, and in a few technical details I'm sure it is better. But my photos already look great. I'm not a pro, but if I was, the 5dIII wouldn't hold me back.
