There are great options for smaller mirror less cameras today that provide all the artistic capabilities of traditional SLRs. For instance, the Sony A7R has a full frame 36 MP sensor, and good options for lenses. Probably 1/2 the size and weight of traditional SLR, with no sacrifice in features & function. Many other options for APS-C Size sensors for less than $400.00 with many lens choices.
It can add up to significant $$$, but if you happen to be ready to upgrade cameras something to think about.
