Amazon offers the Canon EF 85mm f/1.8 USM Medium Telephoto Lens for Canon SLR Cameras for $299 with free shipping. (Many retailers are matching this price or charge about a buck more, including Best Buy via eBay, B&H Photo Video, and BuyDig.) That's the lowest price we've ever seen for this lens; it usually costs $349 or more. It has an f/1.8 to f/22 aperture range.
