Canon’s research division has been busy so far this year, entering several exciting patent applications for products that may not ever see the light of day. Back in March, they patented a moving sensor design, and then in May they filed for an EF 28-560mm f/2.8-5.6 super lens. Last month a new filing emerged for an EF 1000mm F/5.6 IS DO lens, and just yesterday we reported Canon’s patent for a 15-75mm f/2.0-5.6 fixed lens APS-C camera.
Now, if we’re to put any weight to patent applications, we can assume Canon is looking into manufacturing four EF 40-800mm f/4.5-5.6 lens – two for full frame DSLRs and two for PowerShot SuperZooms.
While a 40-800mm lens would be a boon for sports photographers, the technical challenges of producing one that will deliver while remaining useable makes it hard to believe Canon is actually going to make them – but never say never.
