Shooting Canon and AFD3 a couple of weeks ago, got a sore right elbow to this day... Test shooting RZ (outdoor 1st time) with winder, aka coffee grinder, seemed like balancing 10lbs of weight on top of a soap box, i got a sore left bicep. And that my friends is the difference. Any questions?
Ok, so that's a lot of effort to just get an acceptable image that's sharp etc with MF. The life like crispness, in my limited experience with other glass, is only matched by Canon with 85 f/1.2 at near wide open . So you have 1 champ on canon vs most of them on MF.
I have seen drop dead goodness from Rollei/Zeiss (mega price, unfortunately).
Seems that almost very image that you actually manage to get right technically is a WOW image, doesn't happen with DSLR, unless it's the 85 1.2. If the 65, 150, 180 on the RZ are like the 110, and i think at least the 150 is from my indoor test, will find out soon about the others. My rake and shovel leaning against the fence, could go into a coffee table book
In studio the MF/RZ kicks butt with the rotating back, the focus recompose nightmare goes away. Not that manual focus is a piece of cake but more often than not it's spot on.
