The 5D Mark IV might be the big release of the day, but it's certainly not the only news from Canon this Thursday. In addition to the fancy new camera, Canon also revealed two new L lenses—the EF 16-35mm f/2.8L III USM and the EF 24-105mm f/4L IS II USM—and an interesting SD card-shaped W-E1 WiFi adapter.
We interrupt the flow of Photokina camera announcements with a bit of a glass breather courtesy of Canon. In addition to the long-awaited 7D Mark II and the impressive G7 X, Canon also let three lenses out of the bag today, two of which are placed as cheaper alternatives to popular L lenses.
Another leak sprung over the weekend -- if, that is, you believe it's a leak and not a strategic move by the company. This one, however, doesn't have to do with an upcoming camera, but rather some new glass. It's the first official-looking photo of the rumored Sigma 24-105mm f/4 lens.
