Oh, Canon — you and your milestones. Just under two years ago, you took time out of your busy schedule to gloat about the shipment of your 100 millionth compact camera, and today you’re bragging about the production of your 40 millionth EOS-series SLR camera. In all seriousness, we’re pretty proud of ya. After all, it took a full decade (1987 to 1997) for you to conjure up 10 million EOS film cameras, and six more after that to hit the magical 20 million mark. Once you blew through 30 million in 2007, it took but 28 months to get where you are today. What’s really wild, though, is that half of the milestone is all digital, and given the state of film today, we’re guessing that the delta between the two will only grow larger in the future. You’ve come a long way since the introduction of the EOS-1, but we know you’ve got a few surprises in store yet — how’s about a sub-$1,000 DSLR that shoots native 4K video and has an ISO ceiling of 1,000,000 to celebrate the rapidly approaching 50 million mark?
