Adapter lets you mount SLR lenses on iPhone: "There's little doubt that when it comes to snapping spur-of-the-moment photos, nothing quite matches the always-ready convenience of the smartphone. Apple's iPhone is second only in popularity to Nikon's D90 for overall image uploads to Flickr, and takes the top three spots in the Cameraphone category. There are now a whole host of apps available that can help add numerous clever effects to the photos taken with an iPhone's camera, and a growing number of hardware-based enhancements."
