BuyDig offers the Canon EF 100mm f/2.8L IS USM Macro Lens (pictured), model no. 3554B002, for $1,049. In cart, it falls to $899. This $150 mail-in rebate drops it to $749. With free shipping, that's the lowest price we could find by $150, although we saw it for $24 less on Black Friday weekend. This 22-oz. "L" lens is for use with Canon EF-mount SLR cameras.

BuyDig also offers the the Canon EF 24-70mm f/2.8L II USM Zoom Lens, model no. 5175B002, for $2,299. In-cart, it falls to $1,979. This $300 mail-in rebate cuts it to $1,679. (Adorama charges $20 more but includes $80 store credit.) With free shipping, that's the lowest price we could find by $270 and the best price we've seen for this lens alone. It features one Super UD and two UD lens elements that minimize chromatic aberration in the periphery and color blurring around the edges of the subject. Both rebates end January 4.
