What about lens flare and such? The article gave a few reasons how digital lenses are optimized. Nothing in that article was true about the differences? Im not trying to argue just wish you would elaborate if you are going to make such statements here. Thank you.

That article buys one manufacturer's (Sigma's) claim that standard lens design improvements are somehow "optimized for digital." They even admit that by the end of the articl. The only real difference is that some lenses fit a lens mount that only appears on certain digital cameras, and as a consequence, are able to have a smaller image circle.
