Well I've been looking for a solution in situations where I carry two bodies. Have not really been a fan of neck straps,as the cameras tend to swing around a lot and the strap seems to always fall across my viewfinder when I turn to shoot portrait orientation in a hurry.
I was looking at the R-Strap/ Double R-strap set up when I came across this solution here.
Now admittedly, the videos on the site were a little corny for my liking and I was not ultra keen on the idea of the chest harness for two reasons'. Firstly, it looks silly. Albeit I have started to use a belt pack now which is silly enough already, but wearing this you would like you're waiting to start a game of laser tag. Secondly, I hate the heat. Loathe it. Anything close to my body and I can't stand it when it gets hot. So.....the chest harness wasn't really floating my boat. But..the detachable holster, which sells with the chest vest or separately was looking like quite a viable option.
I would be able to add it to my Think Tank belt and be able to carry my second body off my hip. Add a second pin for my primary camera and I can swap between the two when needed. I could do away with the neck straps (use hand straps instead, which I prefer anyway). I really like the idea of these, even though they are ridiculously priced and US shipping is around $55 . We use a similar type of locking system/holster for radios at work...now if only I could find out if the Cotton Carrier locking plate thingies would fit my similarly shaped radio holster....either that or cough up the $$ and get one shipped. Hmmm.
Hope this is helpful to anyone else looking for a similar carrying solution. Will let you all know if I get one and will post my thoughts.
