Originally posted by osv There a few holes in this. First of all, the title should be, "
Lens Mounts No Longer Matter for some lenses on some camera bodies". Secondly the idea is hardly new: m42 'universal' mount, t-mount, tamron adaptall. Tamron, Sigma et al have released lines of lenses with multiple fixed mounts available, covering a broad spectrum of popular camera brands. A wrinkle in this is that they have to
reverse-engineer the firmware to work with ensuing model releases (strangely, Nikon, Canon etc are unwilling to hand over trade secrets). This has involved the owner shipping the lens back to the factory, so the DIY aspect described in the article is a new angle.
How this works in practice, and whether major camera brands will take this lying down, remains to be seen, but two possibilities that spring to mind are: some kind of firmware encryption, and IP lawsuits (think DMCA).
So not quite as advertised.
