I've gotten to thinking about what direction Olympus might take with the new Sync IS technology. Because the roadmap suggests that many of the camera bodies will eventually be getting the firmware update, I expect that they intend to roll out more lenses with OIS in the future. I wonder if they will implement it with the new f/1.2 primes, which would make them even more costly and heavy than we were perhaps thinking. On the one hand, the fast primes will be able to hit higher shutter speeds and wouldn't need it so much. On the other hand, it would make for some unique opportunities. For example, I don't imagine that IBIS would work with Hi Rez mode, because they both require controlling the movement of the sensor. However, OIS would at least be able to provide some stabilization, adding to the ability to shoot hand-held. I am sure higher shutter speeds would also help, and together (along with any other improvements along the way we have been anticipating) maybe this will be a way to enhance the usability of Hi Rez. They might have to do a fw upgrade to allow OIS to kick in independently when Hi Rez is used. One thing I expect would make sense for Oly (but would suck for me) is to make Mk II versions of some of the Pro zoom lenses with OIS built in. Or, maybe Oly will only put OIS in completely new lenses that would benefit most from it. Maybe a Pro macro lens would be in order? Thoughts?
