Excerpt: The lens is a beast in terms of size, weight, build quality. But the sharpness and overall utility is great. Definitely not a "walking around" lens and I have only used it briefly since I got it a couple of weeks ago but I can see there will be many opportunities to use this tool.
Pros: Fast Focus, Improves Performance, Quality Construction, Sharp
Excerpt: I am a photo enthusiast and future professional photographer. I wanted this lens for YEARS! I purchased it and can't believe how heavy it is. I need to lift weights before a day of shooting with it. A tripod is a must have - especially for older photographers like me. Wonderful, sharp pictures, nice lens....just really heavy.
Excerpt: This lens is excellent except for the weight. The color rendering is amazing. I found it is bit softer than my 24-105 L lens but comparing on f4 and up, both are almost same. On my copy, focusing is bit noisy and I found the Image stabilization is OK but not perfect even on tripod! The price is attractive after the rebate and reward otherwise I don't think so. When considering the new technology and market, I will give 4 stars for this lens.
Excerpt: Bougth a copy, got inconsistent focus. I tested heavily but even with a dumbed down shooting (tripod, auto AF point selection etc.), couldn't get consistent autofocus. Microadjust would fix the problem until moving to another shoot with different conditions. I decided I couldn't deal with this and returned the lens. B&H made no problem to do so, thank you. Bought another copy from [*](to get it faster) and have similar issue although much less pronounced.
Pros: Easy To Use, Quality Construction, Stunning Image Quality
Excerpt: While I'm not sure how to improve on this lens, it only rates a 4 because I know that the techs at Canon will somehow figure out how to improve it, make it a 5 star, and I'll be sad to have to upgrade. Otherwise it is an awesome lens and highly recommend it if you can afford it.
Excerpt: I had the previous version of this lens and I like this MkII version even better. I own both full sensor and APS-C cropped sensor cameras and this lens does well on both. I notice the most difference on the full frame sensor however. My pictures just seem to have more clarity because the focus seems sharper. This is my favorite lens!
Pros: Easy To Use, Fast Focus Motor, Improves Performance, Quality Construction, Quiet Operation, Sharp Focus
