As Paul said, you can define any combination of camera, frames and lenses. Up to 500 cameras their lenses (insane) There are provisionss for standard frames but you can define that 5x7 is different than 13x18 and not the external dimensions but the real taking view, as the app is able to provide differences in 'full frame' camera sensors and same focal lenses (for some brands).
Yes is expensive, but yo have something that puts most viewfinders in the basket or at home. It was intended for the Alpa cameras, and a old iPhone 4 more the app price it's less expensive than the beautiful 120º viewer of their catalogue. I have the Alpa WideAngle attachment and for 5x7" you have enough to 72 mm, wider for 4x5".
