Egami has uncovered another Canon patent. This time it's the EF 40-800mm f/4.5-5.6 lens. Frankly, I think this is just a project for some engineers with too much time on their hands. A patent is far from being a prototype, let alone a production model lens.
Currently, the Canon EF 28-300mm f/3.5-5.6L IS is my favorite Super Zoom lens in their lineup. It affords me a wide focal length to choose from when it is impractical or impossible to change lens in the middle of a shoot. The drawback is the weight, Can you imagine the weight of a 40-800mm lens?
I think the chances of this lens coming to market in its present form is zero to none, although Canon is expected to announce a Super Zoom lens sometime in 2017. This type of focal length is very popular and Nikon, Sigma and Tamron all have their models on the market now.
At the present time, I am in Alaska on my annual wildlife photography shoot and was informed by my sources Canon will be adding a brand new feature to the upcoming EOS-5D Mark IV camera. They are playing their cards very close to their chest and not revealing much except to generate maximum publicity and excitement for the launch next month.
