This lens is specifically meant for dslr video, as is the 24 F/2.8 IS. And it being F/2.8 brings IS into the realm of possibilities (relatively small lens elements). The fast primes are built rather tightly, especially the fast ones (little to no space left between elements and groups), and have very large glass elements. Adding IS would require a complete redesign, add elements and groups, and the question really is how easy it would be to do, and how cost effective, apart from potential issues with decentering (larger with larger elements), bokeh, etc.
Kind regards, Wim

Well, this one is certainly fine for still.
For video it would make more sense to go for STM.
