DetailsAvailability: Usually ships in 24 hoursShips from and sold by Amazon.com127 new or used available from $300.00Average customer review:(419 customer reviews)Product DescriptionThe Canon 0345B002 EF 70-300mm f/4-5.6 IS USM Telephoto Zoom Lens has been developedto meet the high-performance standards that todays photographers demand. Improved ImageStabilizer technology provides up to three stops of "shake" correction, and the "Mode 2" optionstabilizes images while panning with a moving subject. This telephoto lens has faster autofocus,and overall the lens is lighter and has a smaller diameter than the original. The zoom ring can belocked at the 70mm position, making this powerful lens easy to transport.Product Details Color: Black Brand: Canon Model: EF 70-300mm f/4-5.6 IS USM Format: CD-ROM Dimensions: 4.50" h x 4.70" w x 7.80" l, 1.39 pounds

Replacing thepopular EF 75-300mm f4-5.6 IS USM, the worlds first interchangeable lens with ImageStabilizer (IS), the lens is expected to appeal to serious amateur nature and sports photographerslooking to achieve outstanding results while shooting hand held.Image StabilizerIS dramatically reduces image blur caused by camera shake. The EF 70-300mm f4-5.6 IS USMfeatures Canons latest 3-stop IS, a one-stop improvement over its predecessor. This allowsshutter speeds up to three stops slower than would otherwise be possible, with no perceptibleincrease in image blur. Photographers normally shooting a 300mm frame handheld at 1/500second can obtain the equivalent result with a shutter speed of just 1/60 second, vastly extendingoptions in low-light conditions.Gyro sensors detect unwanted vibrations, triggering the corresponding movement of a correctinglens group perpendicular to the optical axis. This alters the light path, returning the image to itscorrect position on the sensor or film plane.The EF 70-300mm f4-5.6 IS USM provides 2-mode IS for shooting immobile subjects. Mode 1stabilizes the image along both the horizontal and vertical axes. For shooting while panning tofollow a moving subject, Mode 2 turns off correction in the panned direction and prevents theeffect of dragging the subject back through the frame. IS switches off automatically when thecamera is mounted on a tripod, thus preventing feedback loops between the IS sensor andstabilizer motor vibrations.Superb autofocusThe micro USM motor found in the EF 70-300mm f4-5.6 IS USM employs ultra-sonic frequencyvibrations to drive auto focus with unrivalled speed and near-silent operation. Good holdingtorque stops the lens with precision and accuracy, the instant it arrives at the correct focus pointand without overshoot. A high-speed CPU and optimised AF algorithm result in a significantincrease of AF speed compared to that of its predecessor.
    • A zoom ring locking mechanism is provided that locks the zoom at the wide-angle setting. Thisensures that the lens is carried or stored in its most compact position, preventing possible damagecaused by the lens extending and hitting obstacles when being carried mounted on a camera witha strap.Pleasing defocused backgroundThe EF 70-300mm f4-5.6 IS USM employs an electro-magnetic diaphragm (EMD) with acircular aperture. This helps create an attractive, even defocused background when isolating asubject at large apertures.Image qualityBy optimizing Super Spectra lens coatings and lens element shaping, Canons engineers havebeen effective in suppressing flare and ghosting--more prone to occur with digital cameras due toreflection off the image sensor. By increasing light absorption, coatings reduce reflections offlens element surfaces to deliver crisp, undistorted images with natural color balance.Focal length translates to 112-480mm equivalent in 35mm film format when fitted to EOS 20Dand EOS 350D cameras.The EOS systemThe EF 70-300mm f4-5.6 IS USM includes distance metering information, providingcompatibility with the E-TTL II flash system of late model cameras such as the EOS-1D Mark IIN and EOS 5D . When used in conjunction with Canons range of EX Speedlite flash units, thelens passes distance information to the flash algorithm for markedly improved flash exposuremetering.Accessories for the EF 70-300mm f4-5.6 IS USM include the lens hood ET-65B and the lenspouch LP1222. In keeping with Canons Kyosei philosophy of living in harmony with theenvironment, the lens features only lead-free glass.Customer ReviewsMost helpful customer reviews1048 of 1087 people found the following review helpful.Plain review in plain terms with sample shotsBy Gustavo E. AlfaroThe short version:Pros:The optical quality is great, the speed is terrific, and it compares well to the 70-200mm lens thatpeople like to say blows this out of the water (I believe they are wrong - but we will get into thatlater) and finally, the price cannot be beaten. Buy it.
    • Cons:No hood, extends as it zooms, and the quality of the picture in low light situation lessens a little.The long version:I am writing this in simple terms. I found several, several reviews on this lens but they were allin technical terms and leaves you scratching your head a little. So, if you are like me maybe thisreview will help you.I bought this lens a couple months ago from US1Photo.com (check these guys out. Theyregularly have significant sales and terrific customer service). I use this lens with a Canon 40D.I take several types and styles of pictures so I needed a lens that would do the best job at severalthings and have a very affordable price (right at or less than $1,000). I looked through new, used,third party (Tamron, Sigma, etc) lenses, and read too many reviews and looked at too manyimages to count, and spent four hours in a photography store playing with lenses before I decidedto spend money and take advantage of this lens. All in all I spent about a weeks worth of time inresearch and testing before I bought this lens.---Edit:Okay, so amazon wont let me put a link here. This is how you find me.~Go to Flickr~Then type in a "/" then "photos" then "/" and last type in "gman_five0"And that should take you there.---Test of comment #1:~The Canon EF 70-300mm f/4-5.6 IS USM does not track moving objects very well and thefarther to the end of the zoom the slower the tracking.(Flickr Gallery page 2)This, I have found, to be completely wrong. I have used the lens at several sporting events andfound that it tracks rather nicely. I was able to track every step of a base-runner from first base tosecond, slide, and recovery after the play without losing ONE shot.To see what I am talking about check out my gallery on Flickr. The older ones are NOT donewith this lens or camera and taken, actually, several years ago. I will reference the pictures inquestion.Safe, Got There By a Mile, Breaking Up That Double Play (please note that as time goes on fromthe date that this was posted the pictures may have been re-moved). Also, "Safe" was usedinstead of another shot taken at the same time and angle with a 70-200mm IS lens.To take these shots I used "AI focus" and the "H" settings on my camera for quicker tracking and
    • the H settings for about 6 frames per second.Test of Comment #2:~The 200-300mm range is nice in theory, but a tack-sharp photo from the 70-200mm f/4L at200mm is going to look better cropped than a 300mm full-frame photo from this lens.Again, I found this to be wrong. Though I have no actual "full sized" picture for this if youcomment back with an email address then we can arrange a viewing of one. Otherwise, take myword for it, I own several lenses and this one stacks up well.(Ref Flickr Gallery)The pictures from the Dance Theater and Tashina were all taken at the 200-300mm focuslengths. Again, they are not full sized because of photo pirates, but if you email me we can seeabout full sized shots.Test of Comment #3:~The IS motor is loudI do not know what these people are talking about, but if you call that loud...On the other hand, I have heard (once), the sound of the IS motor, but if you are not listening forit you will not even notice it.Things I have found about the lens:If you spend some time with the lens will be one of your best friends. It is a great lens especiallyfor people on a budget (like me). To take the best pictures you cannot just twist it on and go toshooting. Take the time to LEARN about the lens (change shutter speeds, ISO settings, aperture,white balances, etc) and it will show you where it shines - just like the L series lenses and the 70-200mm IS.This lens has a solid make and feels like it will last forever. Then again, as you zoom the lensdoes extend and is plastic. So, watch out if you are doing sports. You may get it knocked off. Itdid well for me, though. Extending while zooming makes putting a hood on the lens a bit (verylittle; so little that you cannot tell) awkward and it looks kinda goofy.I like the lens because it is not as bulky as the 70-200mm lens and it is extremely mobile. It is asquick as some other lenses, not as quick as some, and quicker than others. It will give you greatquality pictures. It does have its limits, however: in low light situations not being able to take itback a couple stops and get a wider aperture will not give you the same shot as a 70-200mm.Then again, like I said, it doesnt drop to that f/2.8 and does not cost all that money. This hasbeen the single drawback for me about the lens.I use this lens for portraits (Tashina, Samantha), for sports (see gallery), and music (ShawnPander - See Gallery). So, its pretty versatile. I have yet to use with it flash, but that is because Isimply do not like to use flash. I have yet to use it in a studio setting, but when I do I will amend
    • this review and add a couple of those pictures as well.This lens comes highly recommended from me. I am not a big time, highly paid, or well knownphotographer. I just like to shoot and like what I shoot to be of the best quality that I can haveAND afford at the time. So, if you are like me and cannot spend the needed $1,500 - $1,700 on a70-200mm IS lens then spend your money on this lens. You will not be sorry for it.---On another note, comments are welcome. This is my first ever review on here so let me know ifthere anything else that you would like to know about and I will do my best to answer thequestion in the most plain terms as possible.226 of 234 people found the following review helpful.Quite happy with the lensBy pvemanAfter debating between this and the 70-200 L series I decided to purchase this lens. I have beenpleasantly surprised by the results. I also own the 17-85 and the 50mm 1.8 lenses and I havefound that I have gotten the "most pleasing" results from this lens. The pictures have been verysharp from my 20D - even in the 200mm - 300mm range. Ive also been happy with the qualityof the bokeh.The primary drawback I see is that the AF tends to hunt a fair amount when confronted with lowcontrast images. That being said, I used it for some flying bird shooting at the wildlife refuge andwas surprised to see how many of the shots were in sharp focus. However, it was a little bit of allor nothing. Several shots were also wildly out of focus. Since the lens is fairly slow to focus, younever know what youre gonna get with such a fast moving object against the distant sky.I had much more consistent results when shooting soccer, softball and football in the park. TheAF speed did not present an issue for any of these activities and the results were excellent.I wish the lens were a little less expensive but I the prints I have gotten from my 13 X 19 printerhave been worth the extra money.206 of 215 people found the following review helpful.Impressive lensBy Kevin F. GianniniI bought this lens as a replacement for the earlier 75-300mm IS lens. I was generally happy withthat lens, but it had definite limitations - I needed to shoot at f8 or f11 and bump up the ISO toget a decent shutter speed.This new version seems sharp at full zoom even wide open, allowing me to use a lower ISOsetting. Size is similar to older version, but the IS seems more effective - looking through thelens when it kicks in you can actually see the image become more stable and less shaky. I gotthis over the Canon 70-200 f4 L because of the extra reach, smaller size (slightly) and the imagesIve seen from both are very similar.UPDATE: There have been reports of soft images when using this lens in a verticle orientation -
    • however I have not experienced this on my copy. Im happy to say that after months of using thislens, I still consider it great.See all 419 customer reviews...My Associates Store | Shopping Cart Browse by CategoryPatio Furniture SetsCamera & Photo Similar ItemsCanon EOS 60D 18 MP CMOS Digital...Too low to displayCanon EOS 60D 18 MP CMOS Digital...Too low to displayFotodiox Dedicated (Bayonet) Len...$5.28 AccessoriesTiffen Domke F-505 Lens Case - M...$37.99Corel Photo & Video Pro X3 B...$24.99Dolica CF-C58 58mm CPL Filter$15.27
