Remember that only Nikon and Canon us in-lens stabilization. Third party manufacturers want to produce a product that will fit many brands with just an alteration to the lens mount. I would love to see a Sigma 50-500 with their OS system, but they would do be able to offer OS on their lenses for Olympus, Pentax or Sony/Minolta cameras. Apparently they don't think they would generate enough Canon and Nikon sales to warrant the development, manufacturing and marketing costs.
I understand your argument, Scott, but I wonder how accurate it is. Canon is most definitely the most popular dSLR manufacturer at the moment, and Nikon is in the second spot in terms of market penetration. I have no idea on actual statistical figures, but I would guess that Canon and Nikon together would account for at least 70% (if not more) of the total dSLR market at the moment. Certainly that would be a big enough business case for these 3rd party lense manufacturers to come up with something to satisfy a potential 70% of the consumers out there?
