Yes no popup flash as on the D500. Seems logical as new flash units are radio controlled, not driven by the popup flash anymore.

I don't think that it is the best period to launch a camera with everybody on vacations. From a marketing point of view it is better to have a teasing period until September. I don't think we'll ...

As often discussed before, there is a processing power bottleneck that prevent processing high resolution images at 10 fps. That's the reason why the D5 is limited to 20 Mpix. If we assume that ...

See : http://www.photozone.de/nikon_ff/998-nikkorafs10514ff?start=1 Center resolution excellent wide open (tested on a 24 Mpix D3x body though) Or : http://www.lenstip.com/index.php?test=obiektywu& ...

You have to keep in mind that there is inherent photonic noise that can't be avoided. Photons coming from the lens do not hit the sensor in an orderered manner, but with some randomness that ...

Have you noticed that the lens has already been reviewed by lenstip ? http://www.lenstip.com/index.php?test=obiektywu&test_ob=504 You can make a comparison with the 1.8 reviewed here http://www.len ...

The light is diffracted by the edge of the blade, either the blade of a shutter or a diaphragm, it is the same. This is visible first with intense specular light sources, but doesnt noticeably ...

What makes me think of diffraction is the variability with shutter speed. The flare is more pronounced at 1 8000 where the shutter is a rolling little aperture which height is less than 0.7 mm so ...

I wonder if it could be light diffracted by the shutter. At high shutter speed the  blade paerture could be tinu enough to cause diffraction. Same phenomenom as the star effect caused by diaphragm ...

I'm afraid that if you really want sharpness at f1.4 you have to look at 3rd party lenses with modern design, ie the sigma 50 f1.4 Art or the Zeiss milvus 50 f1.4. For the moment Nikon has no ...

Look at this comparison for dxo https://www.dxomark.com/Cameras/Compare/Side-by-side/Nikon-D750-versus-Nikon-D810-versus-Nikon-D3s___975_963_628 D750 has 14,5 ev of dynamic range at 100 iso (2,5 ev ...

Well if you want an all around body, the D750 will better match yours needs. It has a very good iso performance and also a very good dynamic at low iso. And the pixel count (24 Mpix) is a good ...

Personnaly I use a D500 and a D810, as many of us I think. D500 is for wildlife/sports, main use with 70-200 FL, 400 f2.8 or macro. Where the AF speed and the 10 im/s is required. D810 for all ...

Well if you should landscape you should stick at low iso, and take benefit of the extra Mpixels and dynamic range (at least in raw). I shoot my D810 handheld without issue, I use Quiet shutter ...

Try with the Sigma 35 ART which is in your gear list, at f2.8. The nikon zoom is not a dude but it is certainly not design to deliver the proper resolution wide open to match demanding cameras ...

What is the lens ? If you want to take advantage of the high resolution of the D810, you must use a lens capable to deliver enough resolution. I guess you are using a zoom lens wide open at f2.8, ...

For me there is some motion blurr in the portrait. Not thta much, but enough to degrade sharpness. For the plane, a fast moving subject at a long distance - there are many reason that the lens will ...

Within a couple of years all nikon lenses in the portfolio will have the electronic diaphragm. An adaptator for a mirrorless reduced flange distance will be straightforward to build; it will be a ...

Yes it does. Compared to a "true" 24 Mpixels 24*36 like a D750, the iso performance is slightly weaker - we have here the pixel density of a 36 Mpixels camera - but good enough.

When I want smaller resolution I use 20*30 crop format on the D810 - 24 Mpixels in 20*30, factor 1,2 and obviously wider angle lenses
