I have been extremely pleased with the quality and sharpness of the Canon EF 100-400 USM IS. That image stabalizer has allowed me to shoot in lower light situations than with my old lenses. I have wanted this lens since it originally came out and finally purchased it a few months ago. There are only 2 things I can think of that I really don't like about the lens, though. 1. It's heavy. I mean really heavy. Especially after carrying it around all day. Tip: it comes with a lens case. Discard the strap that comes with it and go spend a few bucks on a wider strap that will be more comfortable. 2. Canon really needs to come out with a handle that screws into the lens' tripod mount. It would make it easier to stabalize when carrying a tripod or monopod is not...

I have owned three copies of this lens over the period of 5 years and each of them performed perfectly. Producing sharp image even wide open. I have test my current copy with the Canon EF 400mm f/5.6 L lens and the two lenses produced images that were similar in sharpness and contrast. I duely sold my 400mm prime lens. — — This lens along with the 17-40 and 24-105 complete the entire zoom range required for any normal travel photography with out breaking your back and fits nicely into any medium sized camera bag. —...

With the built in IS I can get up to 3 stops of extra hand holdability. I have created very sharp images using this lens at 1/6th of a second exposure. — — The lens works perfectly as a travel lens for me along with my 17-40 /f4 and 100-400 f/4.5-56 L IS lenses. —...

The lens performs very well for what I use it for, namely landscape photography. I have tested this lens against the more expensive offerings from Canon (16-35) and the 17-40 performs very well at f/8 and beyond. — — If your primary use of the lens is for landscape photography I can stronly recommed this lens but if you are lookign to shoot wide open with this lens you will be better off with the 16-35. —...

This is one of the best canon lenses made for the EOS body. I use this for macro work and compressed landscape photography. It is a manual focus lens so works best with full frame camera. — — I have used this lens with the 1.6 crop factor cameras but fousing was a pain. The lens is very sharp wide...

Back when I was using film, I had a Tamron that was about 25 to 300 mm, IIRC, but it was build to Minolta. When I switched to a Canon digital, I wanted to build on that and bought a Tamron 18 to 200 zoom. — It's been as versatile as I expected, letting me zoom in on animals in Africa or shot wide cityscapes in China (if you don't mind the smog in the way, of course). It's been very durable, with a few bumps and a fair amount of rain not bothering it. The few times I've flipped to manual focus, it's been easy to use. —  The one thing is that...

That's a mouthful. I'm new to camera lens reviews so first let's go through what all of those numbers and letters that look like half an Algebra equation mean. If you're a seasoned camera pro, feel free to skip this section and head straight to the technical specs below. — — First, about the brand: Sigma Corporation of America is one of many well-known lens manufacturers for SLR cameras. They also make the Sigma SD10, a Foveon-based chipset digital camera - technology that makes me drool, but isn't mainstream enough for me to adopt just yet. So, Sigma knows cameras, and they know optics. I trust the Sigma brand to deliver a solid performing lens. — — 12-24mm f/4.5-5.6: The lens is classified as an "ultra wide-angle" lens at 12-24mm. With the 1.6 multiplier the lens is approximately around 19-38mm in standard camera lens terms. The maximum aperture that this lens is capable...
