Here's a list of recently announced Canon Lens discounts on some of the more popular lenses Canon has to offer. I personally have my eye on that 50mm F/1.2L. It's not often you see it down to the new price.
Was $2,299.00, the Canon EF 24-70mm f/2.8L II USM Zoom Lens now at the special price $2049

I will be snagging that 50mm f1.2! Great price review, thanks! Ebay has them for cheapest new, is at $1350. Id much rather get it from BH for $50 LESS. I was already going to buy this lens. What a score.

I can vouch for the 50mm 1.2. I've had it about a year and love it. It's got a bit of a learning curve getting photos in-focus at 1.4 and 1.2 but images are still sharp stopped down that much. I've used it for both what it was made for; low light and nice backgrounds and for studio work. Great lens.
