Not yet really problems carrying my Hasselblad on hiking (but not more than 2 backs, 80 mm and/or 150 mm, no prism); but sometimes a bit lazy, I really like just to carry my Zeiss Super Ikonta (Tessar 3,5/75 mm) with it's very nice coupled range finder, a small lens shade with a yellow filter – and I really can't see the difference in sharpness between this lens and my Planar 80! Unfortunately hard to make normal macro work with Super Ikonta, easier with my Rolleiflex and Rolleionar/Rolleiparkeill and this solution is just marginally more weight.
