As my signature lens lineup, I plan to sell the 17-40L and 100L and get the 24-70 F4L. Now the market price for 24-70 F4 is very attractive, white box version is 30% cheaper to original price. My purpose to purchase 24-70 F4 is for travel and hiking, I think it is very versatile and light compared to my 17-40L and 100L combo.
My dilemma is I love my 100L very much and cant easy let go. Anyone have experience with 24-70 F4 macro performance? Any suggestion?
