I posted this as a response to someone's question but thought it should have its own thread. When searching for info on Sigma's lens compatibility problem, I came across info that explains why the issue exists. It says Tamron and Tokina pay licensing fees to Nikon while Sigma doesn't. Supposedly that's why Sigma owners keep running into problems with their lenses not being compatible with Nikon. And that's why Sigma can't freely allow the firmware to be obtained online. It has to come through their dock.
I always preferred Sigma over the other 3rd party lenses, but if this is the case, it's making me rethink my opinion on Sigma.
