Can anyone recommend a good quality hotshoe optical trigger? All I've found are the cheap ones that I can not get to work properly in a daylight environment. I would love to find one that is as reliable (or nearly as reliable) as the optical trigger on my Elinchrom Ranger which will easily trigger in bright environments. I don't mind paying more for a quality trigger but I can't seem to find one. Thanks for any suggestions! Links are appreciated
