Measuring 78.5x83mm and weighing 540g, it's rather larger and heavier than Canon's now obsolete EF 15mm f/2.8 fisheye prime lens, but still smaller and lighter than the regular EF 16-35mm f/2.8L Quick differences Canon 35 f1.4 L vs Canon 35mm f2.0 IS USM *when I write 35mm 2.0 I actually mean the Canon EF 35mm f2.0 IS USM lens - I just can't be bothered to keep typing all that out! I don't mean the old Canon 35mm f2.0 lens which doesnt have IS* 35mm f2 IS focuses faster - very very slightly, but it does. 35mm f2 is smaller / lighter 6 days ago · The Canon RF 15-35mm f/2.8 L has remarkably low levels of distortion for an ultra-wide zoom. Here’s a chart showing the distortion from 15mm to 35mm: The lens maxes out at just -1.03% barrel distortion at 15mm and 1.83% pincushion distortion at 28mm.

The front element is bulbous, and All-in-all the lens is capable to beat the cheapo EF-S 18-55mm as well as the EF-S 17-85mm IS and regarding sharpness it can even rival the the EF 24-70mm f/2.8 USM L (on APS-C).
