Hello hello. I'm planning to upgrade into a Dslr and have currently a used d80 + 50 1.8 or new d3100 in mind as my budget is around 1.6k.

So wanna have an advice here from all sifu that is the larger pentaprism virwfinder, autofocus motor, dual dial of d80 worth it over the lack of live view and cmos sensor of the d3100?

I'm planning to venture more into high magnification macro photography. Thanks all!
