Hello everybody,
I attended a camera exhibition in Finland today. The D5, D500 and D810 were there for anyone to try.
First the observations regarding the sound of the shutter:
Did several comparisons in a hall which was not very noisy. Tried the D5, D500 and D810 one after the other. All were set to the single exposure mode and exposure time around 1/2000. The most silent was the very silent D810. The shutter of the D500 can be classified as silent although it was not as silent as the D810. There was a slight difference. Clearly the less silent was the D5. - The difference between the D5 and D500 was more than the difference between the D500 and D810. As said all three were in the regular single exposure mode with exposure time around 1/2000. I did three separate comparisons and the result was always the same.
As regards the noise in high-ISO images, I did the following observations:
So far, most of the comments regarding the D500 image noise in this forum are probably not correct. The reason is that the D5 and D500 are in the current camera shows in the demonstration mode. The demonstration mode involves that the image taken can be magnified in only FIVE steps, which is much less than normal. So zooming enough into the image to really see the possible noise has been disabled by Nikon. (Recording on card has not been permitted in the presentation events.)
I had my D7000 with me, and in the D7000 the image could be zoomed in in eight steps (in my D7200 the image can be magnified in ten steps).
I took several comparable images with the D500 and D7000 side by side of a colourful poster with a black wall around. The hall was well lit. Both cameras were in the neutral image mode: contrast lowest possible, sharpening +4, saturation +- 0, brightness +-0, hue +-0. Hi ISO noise reduction off. D-lighting off. Raw image mode. Focal length 16 mm. Distance about two meters. White balance A1. Automatic exposure in P. No exposure compensation.
The D500 could record and display only one image at a time (demonstration mode = no card inside).
As stated already, the images taken with the D500 could be magnified only in 5 steps. The same portion (same width of wall) of the image was displayed by the D7000 when that photo was zoomed in about 6.5 steps (i.e. the D7000 showed a wider image than D500 after zooming 6 steps and a slightly narrower image portion than the D500 when it was zoomed in 7 steps).
High ISO observations done were these: At ISO 6400 both minor monochromatic and color noise could be observed in the D500 images when zooming of 5 steps was done. If full zooming had been possible (instead of only 5 steps) I am sure both monochromatic and color noise would have been clearly visible in the images taken with the D500. I only checked that part of the image where there was black but fairly well lit wall.
After 5-step magnification of pictures at ISO 10,000, slightly more (than above) monochromatic and color noise could be observed in the images taken with the D500. But at that magnification it was still not disturbing at all. If I had been able to do a full zoom into the image, my impression is that a lot of noise would have been visible.
I took the corresponding comparison images with the Nikon D7000, and zoomed to about the same image magnification (same width of picture visible on the LCD). In this case, when the D7000 image was zoomed "moderately", it did not look too bad at ISO 6400. Also ISO 10,000 from the D7000 in minor 6-step magnification looked usable. I got the overall feeling that the D500 was better but not revolutionary better.
The final guess: Nikon does good marketing by not letting the images taken with the D500 and D5 in the demonstration mode to be magnified up to the commonly used maximum level. This creates hype and preorders as people believe that images "fully" zoomed do not show noise. Most trade show visitors do not even notice full zooming is not possible. If full zooming were possible, perhaps no hype would be created.
Certainly the D500 and D5 are magnificent cameras, but my expectations to see revolutionary high-ISO cameras with the introduction of the D5 and D500 have been lowered today. I do expect very good cameras and advances as to the noise level but nothing revolutionary.
I do not have any more observations to present. - I might still buy the D500...
