A patent showing another crazy superzoom has appeared, this time the optical formula is for an EF 28-560mm f/2.8-5.6L USM. We’d assume such a lens would also have IS if it ever came to market. We expected to see a non-L superzoom sometime in 2016, but that has apparently been put off until late 2017 at the earliest.

I’m not sure this is a superzoom we’re likely to see, but all indications point to Canon definitely developing a replacement for the EF 28-300mm f/3.5-5.6L IS.
