The Canon EF 24mm f/1.4 USM L II gave us some mixed feelings during the tests. If you use it at its sweet settings - that's between f/4 and f/8 - the lens will be about as good as it gets for a lens in this class. It's extremely sharp here and there's no significant vignetting to speak of.

The Canon 24mm ƒ/1.4L II USM is an excellent lens, with only two reservations, both relating to the lens' usage on full-frame bodies. The first is some corner softness when used at wide apertures; the second is substantial corner shading, upwards of two stops when used wide open.

The Canon EF 24mm f/1.4 L II USM Lens is a bit soft (not sharp) wide open at f/1.4 - and f/1.4 performance does not look nearly as good when compared to f/2.8 results. The 24 L II steadily increases in sharpness from f/1.4 until becoming razor sharp around f/2.8. Corner sharpness is especially good for a 24mm wide angle lens.
