I took a mamiya RZ67 out to the garden this morning, with metered prism and the winder... What a beast. Tripod was a necessity. Some shoot handheld buy I find it too much for me!
Then grabbed a Hasselblad 503CW with winder and metered prism. Easily handheld. What a compact system. With the manual winder and waist level, it is lighter still! Will be taking it to a wedding(I'm the best man, not the pro) for some shots end of the month and know it packs well, works well and will be perfect.
