I'm curious if someone can help with a question I have about vignetting and pairing up a zoom lens with a S16 camera. If I'm looking to purchase a zoom lens to use with an Aaton or Arri (SR series) 16mm S16 camera, is there any way to determine whether or not the lens will cause vignetting at shorter focal lengths simply by taking into account the focal length range of the lens? For example, if I'm looking to acquire a 7 - 56mm zoom lens, can the minimum focal length alone determine whether or not the lens will cause vignetting, or do there exist some 7 - 56mm zoom lenses intended for R16 that would cause vignetting with S16 while other 7 - 56mm zoom lenses that would be just fine for S16?
If the latter is the case, then what physically makes one 7 - 56mm lens S16 safe while another is not? Is the actual diameter of the optics a little larger in lenses that are S16 safe?
Bottom line, if I'm looking to purchase a second hand zoom lens from a buyer who isn't sure whether or not the entire range of the lens is S16 safe, is the only fail-safe method to actually connect the lens to the camera, set it to the minimum focal length, and have a look through the viewfinder?
