So here is the deal. ill be upgrading to the 70d from my 60D either next week or sometime early next year. with that said i was planning on using my current lenses for stills and video, but the more i read about the 18-135 stm lens and how much better for video they are im confused on what to do as far as buying or keeping.
i currently have the canon 17-55 2.8 is and the canon 70-200 f4. will the 18-135 stm lens be that much better than my 17-55 2.8 for video? if the stm is better than i need to get the 70d-18-135 kit and sell the 17-55 and replaced it with like a sigma wide lens 1.4? this is where im stuck so i would like to know from more experienced ones or the ones that own the 70d and weight my options as what i need to do. im really happy with the 17-55, but if it wont be all that smooth or up to stm i really dont want to be carrying 3 heavy lens.
