A video test of Nikon D90.
Lens: Tokina 11-16
Always with AE-L on, except on the middle when I unlocked and re-locked again.

In general video looks good but the compression is causing artifacts.
No PP, Neutral picture options on D90.
Maybe a more contrasty and sharpened option would be better.

This is a simple amateur ISO performance test of the Nikon D90.

The test was done with Nikkor 50mm f/1.8D , manual focused at 50cm. No sharpening or NR is applied on camera.  The crops are from camera jpg.

1st image (circuit) is with average fluorescent light. Here, even at ISO3200 the iso performance seems (to my eye) excellent !
Colour saturation is very good. Only at ISO6400 the saturation drops a level but noise is well controlled with some smudging. (remember…some NR is applied either you want it or not).

At the 2nd image (low tungsten light) we have a slightly different performance. Up to ISO800 I think the result is excellent. But at ISO1600 I see a difference in colour (small) and noise kicks in. But the image is still very clean and totaly usable. ISO3200 looses much in colour and noise becomes apparent not only at the shady part of the images. Smudging also seems more intense than the 1st image. But again, the image is very good and I don’t see too much of that annoying chroma noise. ISO6400 however is bad. The image has very bad colour. Noise is more visible allover the image an in the dark areas you see very much white spots and chroma noise. I don’t think that 6400 is usable except at extreme conditions.

Santa gave me a new lens (and a camera) to play with…here is a quick test.

Notes:

Nikkor costs ~100Euro and Sigma ~370Euro.
Nikkor does not focus on small Nikons (D40,40x,60) but Sigma does.
Sigma is huge :D

All tests done with Nikon D90 , no sharpening on camera, jpeg (so you won’t see any CAs) large, no PP.

All crops are 100%.
