Canon Is Developing EF 1000mm f/5.6 IS DO Monster Lens.
If you thought that 800mm was not enough for you then Canon heard you and is working on a 1000mm lens. A new patent registered by Canon shows that they have developed the right optics formula for this super telephoto lens.
According to patent publication No. 2016-102852, Canon has developed the optical formula to create a massive EF 1000mm f/5.6 DO lens. DO stands for Differential optics.
Here are the complete details of the patent filing for Canon EF 1000mm f/5.6 IS DO :

A 1000mm lens would definitely be great replacement for 800mm lens from Canon. At this zoom it will work as an specialized lens for specific uses like wildlife and sports. On a lighter note if you can afford this lens then you will also need to afford someone who will carry it for you. 🙂
