Nikon 55-300mm Multiple issues
something wrong... my lens does not do that.
while it is definately not an indoor lens it is still F5.6 at the long end. At F5.6 it should be acceptably bright in the viewfinder and have enough light to AF in outdoor situations. This lens is not blazing fast AF either but it should be able to focus. I suspect something is wrong with the aperture springs/blades/control on the lens
