The Japanese photography blog Egami has uncovered another new Canon patent for the EF-S 55-200mm f/4-6.3 STM lens. Although Image Stabilization was not mentioned, I am certain it is in the patent and may have been overlooked. The STM line of lens are very flexible and are great for taking still photos as well as videos.
It is important to note not all patents make it to the market place but there will be more EF, EF-S and EF-M lenses announcement in 2016.
