Nokishita provided a leaked low-res image of the upcoming Canon RF 14-35 f/4 L IS USM lens that has been expected for some time. Just how much smaller the lens is relative to the 15-35 f/2.8 is hard to determine, although we can expect intrepid Photoshoppers to compare the mount flange width of this poor-quality picture to make some estimates.
Because it is being registered officially by some retailers, expectations are that this will be released this coming week.
