iPhone DSLR Prototype 1.0
An anonymous reader writes with this excerpt: "Here are Photos/Pictures of my iPhone DSLR Prototype 1.0. This is my first attempt at putting together an iPhone DSLR. You might ask 'Why pair an iPhone 3G, iPhone 3GS, or iPhone 4 with a DSLR lens?' Why not!" Prototype or not, it's a cool project.
I wasn't aware there was any autofocusing going on inside cell phone cameras? I thought they simply used their incredibly small aperture and corresponding large f ratio to get a really deep field. Consequently the optical system is very slow, leading to their abysmal low light performance.
