I have owned this for 2 years now and I have loved every second of it. It was my first L series lens and was my only lens for a while. You just can't beat the quality at the price point. Focusing is silent and fast, build quality is great. It is a...

I have carried this lens for little over a year now, using it mainly for real estate photography and landscapes. For this purpose, there was no need to opt for the 16-35 f/2.8, which is double the price. The lens is also great for party shots, when you...

This lens is sharp from front to back and is one of the sharpest in its class, its the only super wide I have used for years and still is my go to lens for the shot. The quality is well build and weather sealed. It never looked faded or used, flare is...

I use the 17-40 f/4L on a 7D body for landscapes and perspective shots. The 17-40 is lightweight, fast-focusing, sharp, and has great color and contrast. The only area where the 16-35 f/2.8L wins is aperature. Bokeh isn't that much of an issue in this...
