I have since extended both cameras. From the image quality, the cameras are identical in normal lighting conditions. In low-light conditions, the D300 can their 51 Focus areas bring into play (D90 has only 11 focus areas). The D300s is less suitable, especially if they work with preset program functions, for example in contrast to the D90 for beginners. Close, Portrait..diese election programs there are no longer with the D300s. The D90 has the yet! The D300s offers a variety of Schnelleinstellmöglichkeiten, without the need to enter the menu. Also it has more features than the D90, for example interval photo feature or better performance in certain areas, for example. Continuous shooting speed, iso-Range, 1/8000 sec etc The additional buttons on the body are not to be underestimated: namely, saving time and you can concentrate better on the pictures. Also pleasant when taking the 100% field of view-finder. Probably the only disadvantage of the D300s is the weight and for some delicate hand the camera size. Noise ratio: is the rest up to ISO 800 in order, but nothing more. Dust: tight like a tank: Unlike the D90 no sensor cleaning was necessary. Viewfinder: compared to the D90 worlds, compare themselves. Video feature: ok but do not skin off your feet. Since I've always my Sony cam View: yes there are always new Nikon models with ever more pixels onto the market. But does not seem to be such that one has the increased amount of pixels on the DX sensor in the handle. Then proved rather old ....?!
