now only joe mcnally has to switch.
im not a big fan of scott kelby but joe mcnally... that´s a different story.
with canons RT flashes he had a reason.
Scott is first and foremost a photoshop guy, an instructor, a musician and then a photographer ... but Joe McNally is a die hard photographer to the core and then an instructor ... if I'm not wrong, from one of his videos, I recollect him saying that he does not get into post processing himself, instead he's got a team of 2 or 3 people who do that for him ... and he is a die hard Nikon user, and he just loves the Nikon CLS as he is really into useing a lot of speedlites in his photography and does it brilliantly ... I don't think he will switch to Canon.
