Query: Outstanding

This is my second Canon L Series lens and was purchased for my 5D2 that replaced my lovely XTi which is now my backup. I wanted the focal length of 24-70 and F2.8 over the kit lens Canon offered with the 5D2. I had the lens for about three weeks and took over 500 pictures. Focus is extremely fast and accurate in combination of the 5D2 (normally ISO set at Auto)even in very low light indoor condition. The picture quality is exceptional and is so easy to catch a moment with sharp picture in every aperture setting, quite often without flash. F2.8 is not as sharp as the Canon 70-200 F2.8L but it is still way better than anything from other brands.This a very well made L lens and you get what you pay for. The weight balance with a 5D2 is perfect for me. Please do not compare this setup with a point and shoot, it is much more hefty. If you plan to get one, which I highly recommend, please pair it with a quality filter.
