Not sure the Mk I is, but the Mk II is judging by this:

The Canon EF 24mm f/1.4 L USM Lens has been replaced by the Canon EF 24mm f/1.4 L II USM Lens in Canon's lineup. The 24 L II features much better wide open image quality, less CA throughout the aperture range and weather sealing.

Yup. Looks like the MK1 wasn't...

"This new wide-angle lens offers far more than a cosmetic makeover to the highly acclaimed EF 24mm f/1.4L USM lens it replaces, and it retains the distinction of being the brightest wide-angle L-series lens in its class. Added professional characteristics include dustproof and weatherproof construction, with dramatic improvements to image quality provided by a total optical re-design and the application of Canon’s exclusive Subwavelength Structure Coating (SWC) to the inside surface of the large front lens element. This special coating is designed to minimize ghosting and flare, especially from extreme off-angle light rays. It combines with traditional Super Spectra multi-coating, to give the lens unprecedented resistance to internal reflections and flare.
