Hello, I've already read through the "645 vs 67" thread, but as my goals are slightly different than the person posting there, I hoped to ask for my own needs. I'm looking to get a film setup, and have decided against 35mm format here, as I would be more likely to use a digital camera for general purpose photography. Personal use: landscape, long exposure, and studio. I enjoy wide angle, usually between 20 and 24mm in 35mm format terms. I don't expect to use these handheld, as (again), I'd use a digital camera for that. I would like to be able to print very large, preferably 18X24 comfortably. I like the higher aspect ratio of 35mm film and digital compared to 4X5, 67, or even 645, but I know I could crop any of these as needed. I would also like the setup to be reasonably light and portable. With regards to volume, I probably wouldn't go through a great number of exposures per month, but it is preferable to keep running cost low. From what I can see, I've got three options: 645 format, preferably a Mamiya of some sort. Lens of choice: 35/3.5N. 67 format, preferably Mamiya RZ67. Lens of choice: 45/4.5W. 4X5" format, preferably a folding camera like a Crown Graphic. Lens of choice: Nikkor 75/4.5. What are your takes on these options, given what I personally would use them for? Would you suggest a setup I've not considered? Thanks!
