How much does it weigh, and what's the minimum speed you can hand-hold it at? Looks great, but your dog looks a bit bored.
Armed with some kitchen scales, here are the weights of my cameras in their typical fighting configurations:
RZ67 + 110 back + 110/2.8 prime + prism finder, 3.2 Kg
RZ67 + 110 back + 110/2.8 prime + waist level finder, 2.5 Kg
Canon 1DII + 28-75 2.8 zoom, 2.1 Kg
Mamiya C3 with 80/2.8 prime, 1.8Kg
Canon Eos 3 + 35/2 prime, 1.1Kg
Olympus 35 RD 40/1.7 prime, 0.5Kg
Olympus XA2, 35/3.5 prime, 0.2Kg
I often carry the C3 or 1DII around with me on a day trip so I hope the RZ67 will not be a bridge too far. It certainly isn't light, and of course i'm assuming hand held shooting with no tripod (hah).
