Hi all. Well santa was very good to me and bought me a 5d mark iii body for Christmas. Of course we all know that the body is only the start of a very expensive hobby. I'm coming off using a Sony HD 550 video camera so, apart from being able to use my Sola 1200's for video lights, I'm really starting from scratch.
So my question is this: how would you start amassing all of the accessories - memory cards, lenses, underwater housing, monitors, filters/ diopters, carrying cases, etc if you wanted to make sure you bought the best, even if it takes a while to buy it all?
What would you buy, and in what order? What is table stakes, what are bells and whistles / nice-to-haves?
My intention is to predominantly use the 5dmkiii for video, but I might toy around with stills if I can. Given I've got no experience with DSLRs, let's say I want to start practicing with the camera topside for a couple of months, then buy the UW housing and go underwater locally. My local playground is Sydney where the viz is anywhere from ~8-20 meters, relatively greenish water with limited opportunity for really wide angle shots. Then I'll take it travelling - likely next stop for that will be the Galapagos - so wide-angle shots mostly. Then after that, it'll be Komodo for muck / macro and wide angle..
Any guidance is much appreciated.
