Negative Positive
Title: Excellent lens
Review: This is my first L lens and I am very happy with it. Owned it for about a month now and I cannot be happier with it. Size, weight, build quality, optics, speed, clarity of images, everything is top notch. I recommend buying an inexpensive tripod collar ring mount instead of mounting the camera to the tripod. I bought the Rainbowimaging one and it is made very well. I was in the same situation as everyone else, deciding between this and the f2.8. I bought this because it is lighter, sharper, newer, and weather and dust sealed. I highly recommend this lens.
