Upload & Sell: Off
Well, I've been shooting the 35L for years now, and it has been by far my most used lens. I recently sold it and got the 35mm f2 IS instead. To me f1.4 is of marginal use, even in low light, due to the ultra-shallow DOF. It is much more useful to me, to have 4 stops of IS at my disposal, than f1.4, f1.6, and f1.8. Besides, I enjoy the much better minimum focusing distance, and the lighter and more compact lens body. YMMV, of course.
Test shots here:
Note that I used the 24-70 f2.8 mkII for two of the tile shots, to compare distortion and vignetting at MFD. Here you also see the vast difference it makes, to have good MFD (35mm f2 IS) and not so good (the zoom, the zoom has max mag at 70mm, too, not 35mm).
