I have a query regarding the Sigma 150-500 mounting on a Nikon D5100.
I have got my Sigma 150-500mm today.... I am feeling that the lens is very tight to mount on my D5100. Is this expected?? I have other Nikon lenses like the 35mm f/1.8 which is mounting very smoothly, but the sigma 150-500 is so very tight that I need to put lot of force to mount it.
I initially thought the vendor may have sent me a different mount but cross-verified myself and with vendor and confirmed it is for Nikon. I am bit scared that it may hurt my cam mount or the lens mount itself if I mount multiple times. Is this normal?
