Out again with the SL2/90-280mm combo . . . which, at the long end, is like having the R 280mm f/4 APO with autofocus and stabilization. Icing on the cake is that I can also shoot 90-279mm . . . well, according to the patent, 92-272mm, as it’s listed as 273mm at the long end. But when a lens is this good, who sweats the small stuff?
