Should I buy a Nikon D90 and D5100?
I am a photographer who want a camera that will grow with me. Basically, I want one that will have the opportunity to play around with more options, and basically customize more of the options (I p + s can only alter the iso in a very limited range and I frustrated). Although this is my first DSLR, I know a lot of aperture, ISO, focus, etc. I am a student and really fast. The camera is created Even better, the 5100 or 90? I ordered my d90! : D
Its hard to say now. The D90 is old age, but still a great camera, though. The D5100 is new, 4 days on the market with the sensor is on the nikon d7000 ($ 1500) of the Nikon D90 is an old, intermediate chamber with a built in AF motor, which allows use almost all lenses in alignment with autofocus. The D5100 no. You have to weigh what you want and do not want. Personally, having the Nikon D40, D90 prefer to have the only by the AF motor-I can use some of the other objectives of my father's auto-focus is most important to me that a better sensor.
