Amazon.com Product Description
Canon raises the stakes for professional photography with its EF 70-300mm f/4.5-5.6 DO IS USM telephoto lens with image stabilization. Thanks to a new triple-layered diffractive optical element (DO), this 70-300mm lens is less than 4 inches (10 cm) long. It can focus down to 4.6 feet (without rotating the front element) and a new zoom lock button keeps the lens safe and secure when not in use or used at the wide angle. A virtually silent ultra-sonic motor (USM) gives the lens extremely fast autofocus. The lens also includes Canon's Image Stabilization technology to dramatically reduce camera shake, compensating for approximately three stops in shutter speed without any perceptible increase in image blur. It's a great choice for professional photojournalists and serious advanced amateurs who need to contain the size and weight of equipment carried.
DO Elements
Use of the new three-layer DO lens drastically reduces the overall length and weight of the lens system increasing the refractive power of each lens element and reducing the spaces between elements. It's approximately 26 percent shorter and 36 percent lighter than any lens of comparable specifications.
Zoom lock
The EF 70-300mm lens features a zoom ring locking mechanism, locking the lens at its shortest total length. This helps to protect the lens from potential damage by preventing the zoom elements extending under their own weight, which might otherwise occur when the lens is mounted to a camera that hangs from a neck or shoulder strap.
Image Stabilization
The lens incorporates Canon's Image Stabilization (IS) technology, compensating for approximately three stops without any perceptible increase in image blur when shooting static subjects or panning. This increases the range of circumstances in which hand-held photography is possible, limiting the need to carry a tripod.
Fast AF
A rear focusing ring type USM, high-speed CPU and new AF algorithms combine to give the lens extremely fast auto-focusing. The ring-type ultrasonic motor (USM) converts ultrasonic vibrational energy into rotational force to deliver high-speed, high-precision, super efficient and virtually noiseless auto focusing, with good holding torque for rapid response and accurate stopping. Full-time manual override is featured, removing the possibility of damage to the autofocus mechanism during manual focus. The lens has a minimum focusing distance of just 1.4m throughout the entire zoom range.
Ready for Digital Photography
The lens shape and coatings have been optimized to suppress ghosting and flaring, making this lens ideal for use with digital cameras that are more susceptible to reflections off the recording media than are film cameras.
Working with EOS
The drive pattern of the lens is tailored to specifically match that of the latest EOS range, extracting maximum benefit from the lens' speed advantage. The lens comes with a case LP1116 and an exclusive hood ET-65B for shading against unwanted direct light.
Customer Reviews:
Outstanding Lens for your 40D or your Rebel xti.......2007-11-21
I have used this lens for 2 years on my rebel, 20 D and now on my 40D. It is an excellent lens and has never dissappointed me. There are technical reviews that talk about some image softness, but I have not found this to be true. It is the best lens you can carry around without a tripod and get a high zoom range. For sports photos it isn't a very fast lens, but you can just turn the ISO up to 800 or 1600 and get great shots ( lbiet with some noise that you can photoshop filter. It is especially and easy lens to travel with and I have taken it all over the world. The lens is supported by DXO optics software that you simply must own if you own a canon body and this lens 9 it takes care of all the lens optic imperfections automaticaly when you porcess the image. It costs a lot but you will be using it a long time. There is no comparason with the L series lens that are much larger and heavier.
A truly superb and versatile lens!.......2007-09-20
I bought this lens to use on my 20D and was very pleased with its image quality, color, and bokeh. I just upgraded to a 5D and this lens is amazing with that camera. The autofocus is extremely fast and accurate, and the image quality is fantastic. I really love short DOF to make the subject stand out and this lens makes it easy. The sharpness, color, and bokeh are spectacular and rival my 24-105 L, and the extra reach in a relatively light-weight lens comes in very handy. A superb walk-around lens that does everything except wide-angle and low light (although on a 5D the low light is less of a problem). I highly recommend it! Image quality is first rate!
Great lens for walk-About +++++.......2007-08-30
I use this lens on a Canon XTi. On that camera it's in effect a 98mm - about 480mm lens. I also use a Canon EF 24-105mm f/4 L IS USM Lens for Canon EOS SLR Cameras. They rate about the same. Both have excellent image Stabilization and great optics. I'm generally torn between the two on which to leave on the camera. This lens is a tiny bit soft at 300 (480 on my XTi) but it has never been an issue. I thought about buying one of Canon's 70-200L series, but they are huge, white, and heavy. Besides I have the 400mm `L' series lens and $$$ goes just so far.
December 22, 2007 - Still a great lens. It's been in use for 4 months and not a flaw. Highly recommend. Not the 70-200 IS "L" series but only in that the 70-200 is f-2.8. But the IM makes up for most of that.
You will be happy with this lens, try it.
Awesome lens if you take the time..........2007-07-27
*Update* A reviewer recommended DxO software (dxo.com) for this lens, so I tried out the demo first with these raw files from the zoo. Unreal results. Just amazing. Prints are simply beautiful. You have to try to believe.
What a great zoom lens. I prefer primes and really wanted a 100/2.0 to go along with my 50/1.4 for my 5D. However, I got a great deal on the DO zoom so jumped on it because of its versatility.
It has to be one of Canon's most controversial/misunderstood zoom lens. The price is one factor and softness the other. The 70-200/2.8 IS takes better pictures (out the box) with less computer work needed later. However, this lens is heavy and white and needs a tripod. But it has terrific quality.
It takes time to appreciate this DO lens. I got so many blurry images in the beginning that I almost took it back. But I decided to take pictures all day to figure it out before my daughter's kindergarten class went to the zoo. This is what I discovered:
-best sharpness between 70-200 is f/5.6.
-between 200-300 is f/11 and f/16
-Image Stabilization is amazing
-auto focus is lighting quick and accurate
-size and weight are amazing for this focal range
Needless to say, the pictures I took at the zoo were terrific hand held. Because it was a sunny day, shutter speeds were high and the images were blurry free. Shot in RAW and WOW when I opened them up. This was "L" class all the way. Now, I understood the price/performance advantage of this lens. After five hours at the zoo and double checking that my group of kids were still with me, I realized it was never obtrusive. There is no way in hell one could have used the 70-200/2.8 IS for that long around their neck and shoulder!
Kudos to Canon for making this technological wonder. Just shoot RAW and the softness goes away and the images are "L" quality. This lens will be with you all the time ready to go. That's priceless in my book!
Exceptional Lens.......2007-07-23
Highly recommend this lens for anyone looking for a medium to long telephoto. Takes great pictures, sharp throughout the range. A little heavier than I expected, but the weight actually helped in holding the camera steady. Before buying the lens, based on other reviews, I was concerned that the zoom would be stiff and difficult to use, but it works fine; zooms smoothly and I had no problem holding it up to my eye while doing so. To hand hold in very low light conditions, setting the camera to 200 or 400 iso setting helped bring the shutter speed up to an acceptable level with very little picture quality degradation.

If you own this camera, you know what an amazing device it is. But who can remember all of those functions?? This CheatSheet is like having the manual on a card - but better! There are simply too many functions to list here but virtually everything in the manual ison this one card. It's a 9"x11" card laminated with a light but durable 3-mil laminate and is folded in thirds. Easy to store at about 4" x 8 3/4" and yet it has the equivalent of a two-sided 9"x11" card. This "take it with you" card is an indispensable resource when taking pictures with this camera. It's an easy to read quick reference that you'll find invaluable. Laminated, waterproof and very sharp and clear, this is a very high quality product
