Should be easy.
Also depends on whether you're on the H1/2 or the Mamiya 645.
The Hassy has quirks that you have to know about if it freezes which is simply taking the battery grip off. But your tech should be no further than three feet from you at all times while shooting and a glance should be enough to call him over to the camera so the client doesn't get nervous.
The Mamiya is a pretty straight forward system but if you need the flash sync then you need the Hasselblad H. You can also go the Hasselblad V or Mamiya RZ route which is just like shooting with it in the film days, but with a small cable from lens to back.
Which ever rental house is renting you the gear should loan you a body and lens with a film or polaroid back for you to play with it at home before the shoot.
If this is your first time, I would only use PhaseOne with C1Pro. It is pretty bullet proof. With Leaf you're asking for trouble. You just never know. With Hassy you can have some issues as well, but it is more stable than Leaf and I have no experience with Sinar neither here no there.
The new P45+ backs are starting to become available and your AD client will appreciate the file of the size. You can hand them the entire job with a version of C1 Pro DB so they or the post house can do what they want with the raw file.
Not sure what kind of work you do that your entire career has never required a Medium Format system. But hey, more power to you. Less headaches and BS to deal with.
Best of luck.
I will be doing a big budget advertising shoot soon and am debating whether to use a medium format digital back, which seems to be the standard for this kind of thing. I have never used digital back before (actually, Iíve never used a medium format camera at all before), Iíve been shooting 100% with a Canon 1ds MkII these days.
I will have a digital tech and full workstation on the shoot, and have the budget to rent a digital back setup. The tech would run the computer and setup and hand me the camera.
My question is: is the learning curve for the camera such that with one day of practice on my own before the shoot, plus my lighting day the day before with the digital tech, can a photographer can be ready to use the camera with digital tech support? (with the digital tech running the setup and software)
Or am I just asking for trouble changing my equipment like this.
I suppose a key element of this question is how much quality gain is there between the digital backs (let's say the 40+ mp top of the line versions) and the Canon 1Ds MrkII. There will be *extensive* post-production involved using a high-end retouching shop for special effects so I need the most robust file possible to push the pixels to their limits.
Any thoughts/warnings/insights would be greatly appreciated.
