I've been shooting video on DSLR for a year or so now and have learnt a lot, however I have basically just been shooting on what I had lens wise, after success shooting with my 550D on a project at work our video department is now looking at adding a DSLR to our kit bag. We are pretty set on using a 600D as the body but choosing lenses etc is the tricky bit. Mostly it will be used to shoot documentary projects and interviews. What lenses do you have and or recommend. Been thinking about Canon 28mm f1.8, Tamron 24-70mm f2.8?
