This lens replaces the previous high quality L-series 28-70mm f/2.8 lens, with a lens of even greater caliber. The range has been extended to cover an ultra-wide angle of 24mm, which makes it ideal for digital as well as film shooters, and the optics are even better than before with two Aspherical elements and a totally new UD glass element. It's now sealed and gasketed against dust and moisture, and a new processing unit makes the AF faster than ever.
Now you can have this great lens for not much more than a "White Box" ef 24-105mm f4L will cost you. It is used and it is apparent mostly on the iconic lens hood. See photo. The lens itself looks pretty good, maybe a 9 but certainly a strong 8+. There are no issues with it as it works as it should.
Price is $800 (same lens at B&H is $1200). My price includes PP and shipping. Just say 'yes'.
