Clearly this forum is not the place to hang out if you're trying to avoid buying more stuff (sigh)
Anyway, yes, I have seen the reviews of the 24-70 f4 and remain confused. I was wondering why so many gave such a high impression of this lens (with the exception of TDP which shows awful performance at 50mm)...I went to my local store to try one out and it confirmed the mediocre performance at 50mm f4 (ok, trying to be nice - it simply sucked at 50). It was very good at 24mm (much better than the 24-105 and close to the 24-70 2.8 II)...got worse as I zoomed in. At 35 it was just ok...at 50 no part of the image was sharp. Center was just barely passable, toward the edges - I thought my 24-105 was meh at 24, but (!!!)...and then it improved again at 70mm but it's still not as good as it was at 24. Macro mode seemed cool but gimmicky at the same time. Performance wise the macro mode seemed to be fairly good (of course, not in the league of the 100L but WAY better than anything in its class).
Basically, with the exception of 24mm f4, this seemed like a step DOWN from the 24-105 which really surprised me given reviews I've read singing its praises. Then, finally I stumble upon some reviews docking it for its performance at 50mm (and threads like this)...I wonder if that was just a bad copy that the store had. Unfortunately it's the only copy they have too...I'd like to try out another one to see if it's any better.
So...sounds like it's normal to see a drop in performance in that lens at 50, but it shouldn't be a dramatic one?
