speedlite

  1. F

    Is it effective to use Canon Speedlite 580EX II with a Canon Lens EF 70-200mm

    f/2.8L IS USM? Considering situations can be indoor/ outdoor with limited source of lighting, etc.

    what lead would i use to connect a Speedlite 430EX II to a canon 40D?

    i think its called a flash off camera lead ? is it hotshoe to hotshoe or something ?
