@srhmoto @Billy thanks, it's appreciated.
Am having a dilemma about my kit as I am starting to shoot more at the bmx track and the hit rate is lower than my (just) 13 year old gets with his d3100+18-105. Am also not happy with the DR really - shadows go mushy quite quickly. There's far too much noise in LE shots.
So I started thinking about my old Nikon and what's about now. D500 / D750 etc would be good but then I'm back into lugging a lot of weight around so I'd have to carefully consider my kit.
Or do I just wait for the e-m1 mk2 and see what happens with that ?
Poop.
