As a beginner to LF photography, I have a few questions I can't seem to find answers to. I recently acquired a Nikkor 480mm lens. I am a bit confused about what size of shutter I should get for this lens. What determines shutter size? Is it the size of the lens? Any help would be great. I am planning on getting a 250-300mm lens as well. BTW, this is for an 11x14 field view.

Thanks, Matt
