If you're shooting with a micro four thirds camera, the Panasonic 12-35mm F/2.8 is in my opinion a must have lens for run-gun with your camera. It's also a very popular choice to use when flying your camera on a drone, or with the smaller handheld gimbals.
It's (equiv 24-70mm) focal range offers decent wide to medium zoom with a constant F/2.8 aperture and offers decent image stabilization. Not the most cinematic lens, but if you had to travel with just one lens for your M43 camera this is it. Right now this lens is discounted an additional $300 OFF, which is the cheapest i've ever seen it. A must have lens in the bag, don't pass up this deal as they state limited QTY at this price.
