I'm responding to Harperphoto's comments about the V being a piece of crap. It's not, not by a long shot. Not one single crap lens: 38 Biogon, 30 Fisheye, 40 FLE, 40 IF FLE, 50 FLE, 100, 180 etc.
RZ, great camera, lenses second to zeiss, second to Mamiya 6/7... and a dog when it comes to portability - it's a beast (but nothing compared to the 680 - good luck using that brick outside the studio). Hasselblad didn't make it on marketing but on image quality.
Rollei 6008, great camera not enough wides.
I like the Zeiss lenses, but there was a time I really did not like them. At all. They have too much contrast, I thought at the time. I liked the RZ lenses better. I guess my tastes changed. I'm now smitten with the 150 sonnar, its the only lens I use for portraits now adays, on any camera system. Its brilliant on the D800 as well as on TMAX at 6x6.
The Mamiya 7 lenses are, by far, the best lenses I've ever used.
I've used the RZ outside of a studio. Lots and lots. Handheld. Annie L used it outside, for everything, for years.
One point in favor of the RZ compared to the V is that the mirror is so well damped that mirror slap is much reduced compared to the V. I think this is because of better mirror travel mechanism, the slight delay between mirror up and the leaf shutter opening, and the GREAT WEIGHT of the RZ. I'm not taking a piss on the V, its just my observation.
Oh yeah, I almost forgot: The RZ's bellows allow for close focusing with ANY lens without resorting to tubes. This is handy.
