Battery grips can be real lifesavers, and sometimes you can’t predict how long you’re going to be out shooting for. A battery grip is essentially emergency battery life, and some grips come with different trays, so you can use single AA batteries or the camera’s custom battery.

These tend to be used by professionals but even if you’re an amateur photographer who enjoys travelling then it could prove to be a worthy purchase. Most DLSR camera models have battery grips made, but they do bulk out your camera slightly. This can be a good thing for photographers with large hands, and it can actually make the camera feel more comfortable to hold, so it’s a lifesaver in two ways, not one.
