My question is: Am I gaining that much using a D800 and the same lenses I'm using now on my D7000? I'm pretty sure I'll be migrating in the next few years to a smaller less mechanical but programmable camera system. Yes, the mirrorless type. Hence my questioning buying a full frame D800 DSLR for little more than landscape and outdoor photography. What real advantages with that and 20 plus Nikon/Nikkor lenses in mind would merit the purchase?
I took some shots of humming birds today and picked a shot (link below) that has about as much detail and resolution and is as digitally neutral (ISO wise) as I would expect from a D800 and the same lens. I mean I'm using an f/2.8 300 mm AI lens that works as a 450 mm on the DX camera keeping the subjects larger than a full frame sensor and the same 300 mm lens. Granted the new sensor should provide more detail and camera IQ.

This is sort of a cabin fever/sick cat sitting question but thanks for any clarity you can impart.
