I just bought a D5100. It came with the kit 18-55mm VR and 55-200mm ED VR.
I have taken a whole bunch of test shots and I'm a little bit disappointed with the picture sharpness. The 55-200mm is a bit better than the smaller lens.
I should say that the pictures look sharp and the colors are great, but if I zoom in 100% using Picassa the edges are not really sharp. This reduces the cropping available.
I should say that I am comparing to my wife's Canon 550D which also has just kit lenses. All shots are razor sharp and can be zoomed and cropped while still getting really sharp pictures. The 550D has a few more megapixel sensor, but I would not have thought it would have made such a difference.
I have tried every tip on the forum and it makes no difference (i.e. hiking up the sharpness in the picture control).
Any ideas? I will probably get the 35mm prime lens at some point as it's said to be very sharp.
Is it noise I'm getting around the edges of the subjects? I'm fairly new to DSLR so I don't really understand noise.
