I have just picked up a new 600 EX-RT as my first and only speedlight, after playing with ETTL and Manual mode; i have figured something strange ( or just i am just a beginner with speedlights and didn't understand it well yet). It is the ZOOM VALUE showed on the flash's LCD, in ETTL with my 24-105 it just work fine,but when i put on 100L it keep showing 80 not 100, even in Manual there is no 100 only 80 or 105, is it normal ??
i have read in the user manual that is manula mode i should keep the zoom little wider than the actual value of the lens to spread the light more....
Thanks for ur help
