Hi Folks, I'm currently searching for a general purpose midrange zoom lense for video works on the canon 5d mark III. The main application will be to use it on my gimbal, which i was able to tune okay with the 100mm f/2.8 (620gr). What I have investigated so far - canon 24-70mm f/2.8 L II - canon 24-70mm f/4 L IS or - a used canon 24-70mm f/2.8 L Downside on the lenses is the focus breathing, and all of them are changing focus on zoom, which isn't such a big issue on the gimbal use. I'm not so sure if the IS is really necessary in that zoom range (and on the gimbal). My current favorite is the canon 24-70mm f/4 L IS, because of weight (600gr, f/2.8 L is 900gr) and not so much overall distortion. The other lenses already in the bag are: - EF 70-200mm f/2.8 IS USM (impossible on gimbal ;)) - EF 100mm f/2.8 IS USM - EF 50mm f/1.8 II Any recommendations appreciated. And it doesn't need to be canon. thanx
