B&H Sales Until January 7, 2012
The folks at B&H have extended their free shipping (in the USA) promo for various lenses that are on sale. There are far too many to list.
There are lenses from Canon & Tamron included in this sale. The best deal I see is the 70-200 f/2.8L IS II for $2069. I also have a soft spot for the 70-300L which is down to $1349 and worth every penny.
