Needs improvement polarization names are in the battery compartment, who changes the Accu`s in the dark, must hope for ambient light.
Furthermore snaps Ww light diffusion plate undressed not one that is then angry when the flash head to the ceiling tends u. Would draw a little light to the subject directly.
For those who like to shoot close-ups: The flash head can be not deeper than straight tendency, but could with a Sigma 18-200 in max. Tele position without sunshade see no drop shadow from the lens.
About the flash output is quite a bit written, the part just great !!
Will save on the SB-800 and continue to use the SB-600 as a slave.
