Have the D7100 for almost a year. Bought as a successor for D90 and D7000. D90 is a bit dated but still camera 1a, the easier to work with. My D7000 unfortunately had delivered defective autofocus as already known and therefore often a lot of fuzzy and few grade so sharp photos and with different lenses ... The D7100 is now the worthy successor for my D90. The 24 megapixels you can actually pick out a good lens with respect to sharpness. The Auto Focus As is known, has been taken over by the professional camera and is reporting good at night and day. The OK button can be programiert order in quickly to zoom when playing back the images to the sharpness I do not want to give her check! So the image quality, speed and Equipment are for the price top! Noise performance is also good can not be compared with full-frame cameras course, this is still the point of the professional Modele for a lot more money and the D7100 here which is intended for sophisticated hobby class differs! The sensor patches I had in the first and the second here, too, but less than in the first, had me then decided the second and retain for 1 month just gabracht to Nikon Service who have made it clean and go since: ) I use the camera with a Nikon 18-200mm lens not a professional lens but is more quality rausholt as the 18-105 and 18-55 as anyway! But do not want to have so I would recommend the camera here each of something more than just entry classes 3xxxx and 5xxxx series of Nikon and Canon Cheap Einstigsklassen wants to spend several thousands of dollars for a professional model.
