I have a Canon 70-200mm f4 and I'm considering upgrading to an f2.8.
There are the two Canon versions the IS and non IS. And then there are Sigmas, a few versions of their 70-200. All my current lenses are Canon but having read some reviews on the sigmas I'm tempted. (I'd also pay a visit to Calumet and try them out)
The reason for the considered upgrade is some weddings that I'm going to be assisting at and one I'm doing myself and I'm wondering if the IS is really necessary. The f4 has IS and I'm thinking that an f4 with IS might be as good as an f2.8 without IS.
Can I ask for your considered opinions on the different 70-200s out there and if it worth the investment in upgrading?
