I'm impressed with the pixel count of the 90D, and wish Nikon would introduce a cropped format with similar, or even greater, pixel count. Unfortunately, the DR and noise of the 90D seems to be still significantly worse than the closest Nikon equivalent, such as the D7200.
To quote from the article:
"ISO PERFORMANCE AND IMAGE QUALITY
I would love to say that the ISO performance of this camera is better than the 7D II. But it is not. In fact it seems to be about a stop worse than the 7D II. I wouldn’t want to have to rely on this body in the rainforest that is for sure. But in normal shooting conditions of ISO 800 and lower the files look good and can certainly be processed to remove most of the noise."
