Thankyou both ,fantastic explanations.
So IQ wise given similar lenses the d3300 leaves the canon 100d we'll behind accordingly then?
Saw a demo of a 3300 and the guy said the kit lens was only a 9MP lens on a 24MP sensor and was pointless buying unless you put a much better lens on.what would be a good lens to get the best out of that sensor,and do higher MP sensors cause some other problems(noise)? if not utilised fully?
Thanks
