I've been impressed by "The Brick" since day one. I bought this to replace my 18-55mm kit lens on my old T2i, and I honestly made the best decision. I've used this lens for landscape, portraiture, automobiles, product shot and even macro. This glass has delivered each time I've used it! Great focusing, very sharp, great contrast and color. Also provides great background blur and bokeh, which is another reason I bought this lens. I have used the 24-70mm L on a Rebel 550D, 60D, 7D, and 5DMK2. It works extremely well for each body, and will definitely cast the best quality each body can provide. If your looking for a lens that is capable of doing more than one style of photography and capable of low-light, then this is definitely the lens you HAVE to buy.Can view sample photos scattered around my Flickr page: [...]
