Adorama offers the Canon EF 24-70mm f/4.0L IS USM Zoom Lens, model no. 6313B002, for $1,299. In-cart it falls to $999. This $200 mail-in rebate cuts it further to $799. With $12.05 for shipping, that's $68 under our November mention (which included a filter kit) and the best price we've seen for this lens. (It's also a current price low by $89.) It features two aspheric and two UD lens elements, full macro shooting mode with up to 0.7x magnification, and image stabilization. Rebate expires March 29.

Update: It's now available with free shipping.
