yeah that sounds about right stwert.
you have a 35mm lens on a 70mm film back (imax). it looks completely different from a 35mm lens on a 35mm film. it looks super wide, like an 18.
what you are doing is like taking a photo and deciding you want to have a wider view. so instead of changing the lens, you keep the lens and change the camera body.
i guess there is nothing wrong with it as long as you know whats happening and why. its not a good habit to get into if you ask me.
