It took Canon a long time to feature IBIS (In Body Image Stabilization) on their…
Canon patent for a EF 24-300mm f/3.5-5.6 USM lens for full-frame sensors. The patent description doesn’t mention image stabilisation (IS), so it’s unlikely this will be the replacement for the Canon EF 28-300mm f/3.5-5.6L IS (announced 2001).
As usual, a filed patent doesn’t mean the described gear will necessarily hit the market. On the other hand, this may just be a patent on the way to the replacement for the 28-300mm f/3.5-5.6, and we could soon see another patent for a similar optical formula and with added IS.
