[QUOTE="TieuNgao, post: 474599, member: 6993"] There are two separate issues: backward compatibility and open code practice. When a piece of software is updated/improved it's not always possible to make it backward compatible, even for the developers' own software, let alone the third party's ones. But whenever Nikon produces a new camera model with a new processor or new AF algorithms it has to make sure that all the Nikon old lenses will work with the new camera. In the open code practice world, all the competitors' lenses will also work as smoothly as Nikon own lenses. The current practice in camera business is based on proprietary software. Some of you may recall the cases of IBM OS/2 vs MS-DOS and Beta vs VHS in which the open code practice won! [/QUOTE]
