So... what does it take to have software recognise a lens? Obviously
It takes two things: the software must understand the particular camera vendor's data in the within the image data, and the software must have a list of all of the lens codes for the platform. In Pentax' DSLR vendor data, the lens is represented by a sixteen-bit integer, so it theoretically could recognize about 65,000 different lenses. However, the lens manufacturers have to give each model unique "lens model numbers" out of those 65,000 possibilities. If the third-party vendors don't coordinate with each other and the primary vendor, you can get multiple lenses with the same code number.
