Plain sailing. Don't mark on your VISA that you are doing photography/video work as it could screw things up with a lot of paperwork and further approvals. Follow all standard protocol on carry on weights and batteries, they can be very picky in some of the airports there about ion lithium batteries and your baggage weight. I recommend a travel vest or something of the sort to stuff your pockets with gear from your carry on bag if they give you problems when weighing, and then simply repack the bags from the gear in your 22 pocket carry on vest once you're through weight with your bag approved.
