Big news in the camera world, courtesy of our friends at PopPhoto: Canon just announced its first mirrorless interchangeable-lens camera (ILC). ILCs are great because they take, largely, the core features and image quality of a DSLR and shrink them to near-point-and-shoot size--plus, you retain the ability to swap lenses. Sony has owned the category lately, but Canon's EOS M has most of the internals of its currently excellent Rebel line of entry-level DSLRs, including the same sensor as the T4i. It'll retail for $800 when it's released in October. Read more at PopPhoto.
