Although I don’t have any experience with other 400mm lenses, from any brand, I think the Hexanon AR 400mm f/5.6 UC lens may not be considered a sharp one under today’s standard. But I have to spend more time with it to get a better idea about how to make the best of it. As I have been mainly a wide-angle shooter, using telephoto lenses is fairly new to me. Maybe I’ll learn something along the way.
Oh, mosquitoes are very annoying.
