I have seen some graphs that show the 24-105 getting softer wide-open. I have a done what you are doing now!! I have my kit lens(18-55)that I rarely use. It is a decent lens, never the less. I have a wide angle 17-40mm L. Pretty awesome lens!!! I have a 70-300mm which is also an awesome lens. I also have an 85mm 1.2L MKii, and a 100mm Macro. The two fixed focal length lenses are on my cam most of the time. I have just ordered a 50mm 1.4, and will order the 70-200mm IS USM on Monday. A partner of mine let me borrow the lens for a concert shoot and it rocked!! I like the ability to zoom, but I love the fixed lenses.





I keep hearing that 50mm 1.4 just gobbles up light, and is super sharp starting at f2 or so, and keeps getting better, vs the 50mm L being really sharp wide open, then losing some sharpness at smaller apertures. Ditch the 24-105mm, go for the 50mm 1.4!
