Canon EF 70-200mm f/2.8L IS USM Telephoto Zoom Lens for Canon SLR Cameras

It's really difficult to add something new as everybody agrees that this is an amazing lens. Before I bought this lens I had owned Canon 70-200 f/4 non-IS version. It was also excellent lens in terms of image quality but this one adds faster aperture and more importantly excellent Image Stabilization.
Lens is really heavy comparing to non-IS version of 70-200 f/4 but that extra weight is worth of it. Pictures are excellently sharp, you can shoot hand-held with times below 1/100 sec. which is a dramatic improvement.
I believe any of Canon 70-200 lenses is great but not each is usable in low light conditions without tripod. 70-200 f/2.8L IS excels in such situations so if you're sure you'll be dealing with low light, this lens is for you.
It's excellent for wedding photography, portraits, nature, animals etc.

I bought this lens for shooting softball action in early evening, twilight, and night games. The autofocus is unbelievably quick and impressive. It's important to remember to set it to IS mode 2 during action. I forgot a few times and the images were not clear enough. The zoom ring is smooth and is conveniently placed. I chose this over the 80-300 mm because the 70-200 got better ratings regarding picture quality and it has the f/2.8. The range of 70-125 is great for infield and shallow outfield, but beyond that it needs to be on a tripod or monopod. I'm thinking of renting 100-400 to see if that works better for my needs. I've taken a few shots indoors of my dog and wasn't impressed -I'm sure it is due to my lack of skills and not the lens itself. I haven't learned to use a monopod so I've been hand holding it while attached to the Canon 40D. I don't think it's too heavy, but I've been getting flair-ups in my carpel tunnel pain the day after using this lens.

This is a wonderful lens. Well worth the money. The senior portraits I took came out beautifully. Works great for outdoor shots!

Sheesh...after reading all the reviews, buying this lens, and using it...what else is there left to say? You'd be wasting your time on other Canon 70-200 lenses. IS and f/2.8 is the way to go.

I have done a lot of researches before decided on getting this sweet baby. I chose this over the regular f2.8 and f4 IS because I know I want the best. A lot of people complained about the weight and I have to admit it is quite heavy especially carrying it the whole day. After the first day of shooting, I couldn't wait to put my CompactFlash into the digital photo frame to evaluate the quality of the pictures. I immediately forgot about the weight and I appreciated so much on the picture quality. Then I remove the card and load all the pictures on my 24" IMAC. The result are more stunning! Next, I tried printing one of my best shot onto a premium photo paper. You know what I am going to say! The image is tack sharp with great contrast. I tried a lot of other "L" zoom lens including the f4 non IS and none of them give me the same level of quality images. Although I still think prime lens are the best for quality but I don't think you can find a better zoom lens on the market. This is the one!
