Personal Opinion

With the huge EW83D lens hood on, this lens looks almost the same as the EF17-35mm f/2.8L.

The Manual Focusing ring on my test lens felt stiffer than what I am used to on my other EF lenses. This is not exactly significant since I know that with more use, this stiffness will disappear.

It focuses as close as 0.25m, which is extremely helpful in environmental shots in physically-constrained locations.

The surprising thing about the AF is that it "glides" into focus. By comparison, the EF17-35mm f/2.8L seems to "snap" into focus. The difference between AF speeds is not as obvious as that between the EF100mm f/2 USM and the EF85 f/1.8mm USM, but was obvious enough to have caught my attention.

Attached to an EOS1n, this lens felt well-balanced, and IMHO, was easier to manual focus than the EF17-35mm f/2.8L since the MF ring is at a further distance away from the lens mount. I especially liked the thick (1cm) MF ring.

Conclusion? Get this lens if you need quality at wide angles and you need the large f/1.4 aperture. Otherwise, the several times cheaper EF24mm f/2.8 might be the one you are looking for.
