I choose bodies for the ergonomics and what's available in the mount, not what's available in 1st party form.
I differ from that in that I don't trust the quality control of third party lens manufacturers on the whole. Carl Zeiss lenses are a notable exception to that generalization, and the Cosina/Voigtländer lenses have proven to be very good as well. I consider those two to be on par with original manufacturers' lens offerings or better.
I particularly detest Sigma lenses for their utter lack of consistency. Get a good one and they're likely decent performers, but the odds are stacked against getting a good one in my experience.
