With short-focal eyepieces, the effect is negligible, but with the focal length, the pupil can move away much longer than was intended for the design of the glasses, which in many cases results in vignetting
the optical viewfinder(OVF) and electronic viewfinder(EVF), and automatically selects the OVF magnification and">frame size according to the focal length of the attached lens for wide-angle
However, since the focal length of any lens is based on the focusing distance at the infinity setting(and Tamron's high power zoom lenses provide the same angles of view as other telephoto lenses at the infinity setting),
allow you to extend the focal length twice while taking pictures of the sky in the lens focus.
I suspect the focal lengths at the telephoto ends might actually be shorter than designated.
