I will probably burn in Pentax hell for this but currently I am practicing with this lightest always-on-me DSLR set I could come up with so far.
NIKON D3500(365g); NIKON 35/1.8(210g); TAMRON 16-300 (540g) = total weight 1115g = 2.46 lbs
Who knows, maybe come July I will be in a much better form and an extra kilo or two won't make a difference, I sure hope so. My dream is to be able to use the 15-31-77-300-K3 kit and still breath normally after the 5th mile of the hike
I am 5'8", 54 yo, and not in great physical form (yet) so every gram matters to me.
Btw, while looking for the lightest Pentax DSLR I found Pentax K-S1 at 558 g, not bad for a feature-full body. But, I don't own one of these.
