Some reasons an EPL6 is not the best for this purpose: 1) as someone else mentioned, adjusting settings on an EPL6 takes longer, thereby removing critical-response flexibility 2) The EPL6 cannot reasonably carry a good flash head. Even if put in a flash frame, it would be quite odd to handle 3) AF could be better (the upper end EM series would be a better choice, because you only get 1-shot at a lot of this stuff) 4) Can't grip an EPL6. A grip helps for holding for a wedding for a long time. The camera needs to be ever ready at a wedding, not in a pocket, etc. Also, a proper battery grip gives you extra battery 5) higher end (=more surety) would also be to use a body with dual card slots, so you don't face card failure (again, think once-in-a-lifetime shots) Reasons the kit lens is sub-par 1) very limited DOF control. 2) small aperture. If you go to 42mm, you are now at f/5.6, so unless you are outside, ISO has to jack way up. As ISO goes up DR and color response drops. You could move to a flash, but then you are at #2, above 3) Color and contrast on the kit are OK. You can do better for a once-in-a-lifetime shot. Same with sharpness Overall, two bodies is better than one. A 70-200 (or equivalent) on one, and a wider, brighter zoom or prime on the other. The class is a 24-70/2.8 and 70-200/2.8 (in FF terms). It's a big reason those two lens exist. Once you go to those lenses, you need a body (or two) that can manage them.
