Sigma AF 28-135mm f/3.8-5.6 Aspherical IF Macro

Canon EF 28-135mm F3.5-5.6 IS Lens I use this lens as my walk around lens on a Canon 20D. The Image Stabilization works great and adds at least a stop in low light for hand held pictures. This lens is well built with USM for fast auto focus. The images I get with this lens match up optically to the L lens I use and that is why it is on my camera more then the rest. My L lens are used for wildlife and scenic photography and this is used for my people shots, close up's of flowers, and walking around. This lens lets you focus up close and you have almost a macro lens when used at 135mm. If you are on a limited budget this lens is a best buy and the most value for your money. I've sold as many images taken with this lens as the L series lens in my bag. Lens Kit owned Canon EF 300mm f4 IS L lens Canon EF 400mm f5.6 L lens Canon EF 17-40mm f4 L lens Canon EF 70-200mm f4 L Lens Canon EF 100mm f2.8 Macro Canon EF 28-135mm f3.5-5.6 IS lens The 28-135mm IS lens is light and very easy to carry and to use to get great images. The image quality in terms of looking at images taken on a photo shoot when compared to the L lens in my bag is similar enough to not be noticeable. The lens has a different use then most of the lens I use but it works well and the images are crisp and sharp with great color. I have owned at one time or other shooting film and now digital most of the lens in Canon's EF lineup that had a reputation for shooting excellent images and this lens matches up very well with all of them.

Probably The Best Walk Around Lens There IS I recently purchased this lens, and have absolutely no regrets about it. This lens focuses extremely fast, and is super quiet. The photos come out awesome in both sharpness and color. I could not be happier. Haveing no L lenses I can't compre it to them, but I find it hard to believe that they would be that much better then this one as far as quality of the photos are concerned. I have tried it in all lighting situations, and yes the IS system really does help in low light situations. The range of this lens covers most shooting areas (28-135mm)that anyone will encouter, especially with the 1.6 crop factor taken into consideration on the Rebels and 10/20/30Ds (makes it a 45-216mm). So this is a great walk around lens, and has become the one that stays on my camera now probably 95% of the time. I have removed two of my other lenses from my camera bag since purchasing this one, one of which is the Tamron 28-75mm f/2.8, which is an awesome lens in itself. This is one superb lens that I would highly recommend to anyone using a camera made by Canon that utilizes the Ef lens mount. The only other Canon lens compariable is the 24-105 "L", but for less then half the price you can get this one. So for those on a budget, like myself, that doesn't include the "L" glass, then this is definately a must have lens for your camera bag. Pros: 1. IS System (awesome for low light) 2. USM (super fast and accurate focusing) 3. Quality of photos (always a must) 4. Could list multiple more reasons to have this lens, but will stop here. Cons: Haven't found any as of yet, and at this point I don't think I will.

Canon's best value all-purpose lens Canon's 28-135mm IS is a great lens even if you buy it on it's own... but it becomes and incredible deal when bought as part of a D40 kit. The first thing that is noteable about the 28-135 is that it is not a kit lens, and it is not an EF-S lens. This lens was designed to work on full-frame cameras, including film cameras, the 5D and the 1Ds series. That means it is also a good choice for a 1D series camera (with the 1.3X crop). Of course it can also be used with the 1.6X crop EF-S compatible cameras like the Digital rebel, 30D and 40D. I've owned this lens twice now, once some years ago before a switch to Nikon, and now I own it again having bought the D40 kit which included it. I find myself using it all the time, and in fact I sold my 24-105mm f/4L because I felt the 28-135 was close enough in quality and capability. Photos are sharp at any focal length, and I have never experienced lens flare. Distortion is well controlled, as is chromatic abberation. Focusing is adequate, as is the IS function, but these are the areas where performance is less than the $1000+ L lenses... still for a full-frame lens of this quality, these are compromises I am willing to make since I saved $800 by swithing from the 24-105 to this lens. In summary, Canon's 28-135 is an optically excellent lens with adequate focus and IS capabilities, available at a good price and compatible with all of Canon's EOS cameras. There are few lenses like that in either Canon or Nikon's line-up.
