Camera and guns have a good amount in common – you know, the whole point and shoot. So it’s no surprise to see a red dot sight for a camera mount. Officially called the Wildlife Photography with Tactical Four Reticle Sight, it has four reticles (Point, Circle Point, Circle Cross, Cross) and can switch between a red and green laser. If for some reason you’re not down with things being centered you can move the point around according to your liking.
It should fit on most SLR hot shoes and costs $46 from Brando.
