Hey guys and gals! Question. Every lens I own, with the exception of prime lenses, have IS built in. I'm interested in maybe purchasing a canon 70-200 2.8 lens without the IS and also maybe that 24-70 2.8 lens without the Is but the non IS is what scares me. I shoot mainly weddings and engagement shoots and do not use tripods. From my understanding, the longer the lens, the more it issues it may have if its a non is. So I guess my question is, do any of you use non IS lens on a regular basis without a tripod for weddings or anything similar and have any issues or not?
