Summary: This lens is amazing. The picture quality is superb. However, after spending a few hours taking landscapes photos some of them were not sharp due to human error. You have to remember to set the infinity setting on the lens itself or some pictures will not be sharp. After I corrected the setting the pictures looked fantastic. This is a setting I know will be hard for me to remember. Otherwise, I am very satisfied with the lens. The construction is first class.
Summary: I have only had a DSLR for a little over a year now, having the T1i which came with the kit lens and the 55-250mm lens. I was totally dissatisfied with the tele-zoom lens it came with. So much so I had given up on getting any wildlife shots. However, my passion over-rode my resolve and I decided to give a good zoom lens a try. The lighter weight of this lens and the f/4 are the two factors that made me decide to get this lens.
Summary: My first L glass. The only bad thing I can say about this is now I am spoiled and will only buy high quality optics. This is worth every penny. The return on investment on these lenses is great. I have been watching the market on used L Series glass. They resell for a very good price. The image quality speaks for itself based on the existing review alone. This is second to none.
Summary: I've read the reviews and agree with all the positive remarks. Its a wonderful addition to your collection and you will not be disappointed. The pictures are tack sharp and the autofocus is extremely fast. The bokeh is also really nice when taking portraits, its really a great steal over the 2.8 considering weight, price and quality!
Summary: I traded in my Canon EF 70-200mm f/4L USM lens for this new lens. The colour of this lens is a slightly darker off-white (almost gray-white) than the non-IS version. So, if you have an older Canon Tripod Mount Ring A (W), you may see a slight colour mismatch. Personally, not a big deal by any means.
Conclusion: I purchased this lens for a European River Cruise over Christmas and New Year's. The results were outstanding. I am not a pro, but the night shots and the 200mm shots of castles along the Rhine were fantastic. Another photo-enthusiast was particularly impressed with the telephoto night shots. Great lens for the money and very lightweight.
Pros: Fast auto-focus, Superior build quality, Super-sharp images
