Canon EF 24mm f/1.4 USM L II - Review / Test Report
26 January 2010
Conclusion: 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.
