I have the 17-55 2.8 and 15-85mm and not sure if i should add a tele photo or a prime or wide angle. If my dreams of getting a ff camera right now are unachievable then justvtrying to figure out my next lens. I shoot family photography and lifestyle. Also considering the canon g1x for when my dslr will not be plausible. Any thoughts of what your doing out there?
