Question for you all: would you use the 25PL if you also had the 12-40 in the bag? I'm curious to know how the latter performs at 25mm. I know the typical answer is to think of the difference between 1.4 to 2.8, but I would say I find myself rarely shooting wide-open at 1.4, more like 1.8-2.2 (and I suppose this might be true for many of you out there? or not?). I'm in the market for 12-40 so I'm wondering whether I should sell the 25PL at some point. Any feedback on your personal experience using both appreciated!
