Thanks mate! So I've been using a Phottix Plato remote shutter. It enables you press the button once and then the camera keeps on shooting till you press it again. I just press it, then wack it in my shorts till I need to press it again to stop.
The only issue is the range, which is listed as 100m, but I usually get more like 50m. Means I have to set it off when I'm close and then get back in range afterwards to shut it off... I have a shit ton of shots to discard afterwards!
Tbh I'm looking to get a remote with a longer range, I've heard the Pocketwizard Plus III's have a pretty banging range and some useful range extender features. Quite pricey though!
