Actually it is a costworthy camera but after usage of two to three months it continuously resists its shutter problem .
overall experience was good but I think that the canon is best than nikon and specially best than nikon 40d
it always lags with a shutter problem
and within one year and five to six months my camera started to throw out lens .
I mean just I have to push it back again and again
again and again to get lens attached
I think its a costworthy camera but as per my thinking u should think twice before buying it.
