Here is a new Canon patent. One that will for sure start some bs rumors…
Canon EF 16-600mm f/2.8L IS USM Lens Exists And Is Shipping
No rumor surfaced and no specs leaked, but here is the proof that the lens is real! Canon surprised all with a brand new lens no one was expecting, the EF 16-600 f/2.8L IS USM lens. A lens that should cover all your focusing needs, going from ultra wide angle to super telephoto zoom with a constant f/2.8. No pre-order options so far.
