It was designed for night surveilance photography, so it is optimum or near so wide open! You DEFINITELY will want to pick up the original 2x extender, and don't spend the extra $$ on the newer APO converter for this lens, as the original extender was designed with the 3.4 lens. You will have an excellent 360 6.8 for an extra 200-250! Again, don't be afraid to shoot it wide open, even with the extender! ........ Tom Schofield ----------- That is very useful advice.
