I shoot with a Canon 20D and before purchasing this lens, used the Canon EF 75-300mm f/4.5-5.6 III USM lens. I've always noticed the limitations of this lens when shooting amateur softball. I reviewed the lens lineup at the Canon website and decided on purchasing the Canon EF 100-400mm f/4.5-5.6L USM Lens. The 100-400mm is a great lens, but it can be a little soft. For that reason I decided to add the Canon EF 70-200mm 2.8/f IS USM telephoto zoom lens to my lens collection.As an L lens, there are numerous features and is manufactured with high quality materials and a higher level of dust and moisture resistance compared to the standard line of lenses. This pro quality lens is meant for serious photographers with high demands of their equipment. The construction is sturdy and consists of 23 elements in 18 groups. The four Super UD-glass elements largely eliminate the secondary spectrum reducing residual chromatic aberration. An improved 8-blade circular aperture offers a more pleasing out-of-focus image. The Canon EF 70-200mm lens weighs in at about 3.24 lbs/1,470 g, and a minimal focusing distance of 4.3 ft/1.3 m. The front thread accepts 77mm filters, be sure to get a 

good quality UV haze filter









to protect the front lens element. This lens is compatible with the 

1.4x II









 and

 telephoto extenders.Being white, this lens looks out of place, but helps it stay cool when shooting out in the sun. Some people are concerned that being white, it attracts attention to criminals. From my experience, my 20D attracts attention regardless of what lens I put on it. In addition, I most likely have a camera bag and tripod/monopod with me to further attract attention. I personally doubt a thief looking for something to steal is taking the time to evaluate the cost of the item and are more concerned with the ease of taking something they can unload. I try to make things difficult for would be thieves and have my equipment insured as a back up.The dual IS system has two modes. Mode 1 is for stationary subjects while mode two is for moving subjects. It is recommended that the IS function is not used while using a tripod; however I have successfully used this feature while on my monopod. The IS helps to eliminate camera shake and helps stabilize the lens when shooting from a moving vehicle or in low light situations. While there are limitations to what the IS can do, it can give you a few extra stops. Just keep in mind, the IS attempts to eliminate camera movement, not the movement of the subject being photographed.This lens permits for auto or manual focus depending on how the switch is set. There is also a switch to shift from a 1.4m/4.6ft to infinity or 2.5m/8.2ft to infinity.Included with this lens are the tripod mount, lens hood, and storage case. The tripod mount is the best option to use when mounting to a tripod, helping to maintain balance. Mounting the camera instead creates an unbalanced set up that may topple over. The case is a 

zippered soft case (LZ1324)









 that can also be purchased separately. The 

lens hood (ET-86)









 is used to reduce lens flare and can protect the front element in certain situations. Often times, Amazon recommends purchasing the lens case and hood, however they are normally included with the lens.The Canon EF 70-200mm is such an awesome lens, it almost fails to compare to the 

Canon EF 75-300mm f/4-5.6 III USM telephoto zoom









. The 

EF 100-400mm f4.5-5.6L IS USM telephoto zoom lens









 is a well used option for me, but the clarity and sharpness of the 70-200mm IS lens is more refined. I doubt the 100-400mm lens will be replaced by this lens as a favorite. I find the push/pull focusing of the 100-400mm lens to be a benefit that the 70-200mm cannot replace. This lens can be used for portraits, landscape, sports or as a general walk about lens. The f/2.8L combined with the IS makes this lens a good option for certain low light situations. The features add creative versatility. The Canon EF 70-200mm IS lens comes at a price, but it is worth every bit of it.PROS:Incredible clarity and sharpnessQuiet and quick auto-focusFeatures add creative versatilityDual IS systemCONS:Heavy and bulky (This should be expected with these types of lenses)

After shooting with my older EF 70-200mm 1:2.8 L IS USM for years, I started to notice that my images were softer than those taken with my other (newer) Canon lenses. I had it cleaned and recalibrated and while the results were better, I realized that it was probably time to replace it with the most current version.The new Canon EF 70-200mm f/2.8L IS III USM Lens is somewhat lighter and MUCH sharper. I just returned from an out of state nature shoot where I used this lens extensively hand holding it mostly at 200mm. All the images are tack sharp with excellent colour and detail.The 70-200 has always been my 'go-to' lens for many situations... I love the flexibility to choose either lovely bokeh backgrounds or excellent depth of field depending on the situation and the results I'm trying to achieve. This is a GREAT lens and although it's a bit pricy, it has already proven to be a professional tool that does exactly what it's supposed to.I'm really loving my new Canon EF 70-200mm f/2.8L IS III USM Lens and am glad that I didn't 'cheap out' with a less expensive competitors product.

just got this lens and so far i like it better then the canon 70-200mm lens i just returned . its super fast and quiet . ill be testing it out further in the upcoming weeks.

I paired this lens with a T6s crop body that I have been shooting with the last two years. My decision was based on intended use, value and cost. I considered Tamron, Sigma and Canon for this purchase.Specifically:Tamron SP 70-200mm F/2.8 Di VC USD G2Canon 70-200mm f/2.8 IS II USMSigma 70-200mm f/2.8 EX DG APO OS HSMObviously these lenses are in a different performance category than the 70-300mm f/4 I purchased. The primary consideration here was weight. I had just spent a week in Paris with 2 lenses. I did well with the canon 10-18 and sigma 17-70 f/2.8. What I needed was some additional reach beyond 112mm in a package I could travel with. The 70-300 (this lens) is the answer. The sigma worked well in the majority of my low light (no flash allowed) situations, but I didn't have the reach I needed in many cases. I've had some very favorable results with the APS-C format. I feel like I'll have that coverage now in a "travel friendly" package since it just isn't comfortable or practical to carry around a hefty 3.1lb f/2.8 lens when you are sightseeing.I took the time to read the lenses manual before it arrived. The build quality is good. Although mostly plastic, the lens has some heft, but is only half the weight of a f/2.8 with "L" glass. The LCD display is cool. I've been taking pictures with SLR and DSLR long enough so that DOF is more second nature. Will have to see how much I actually use it. So I put the lens on my camera and started shooting. The focusing system of the nano USM motor is truly fast. Great for video too.. It's quiet (near silent) My first shots were at 112, 216 and 480mm, subject at about 15' and wide open. IQ was good for a lens at this price point, no vignetting was noticeable at 112mm. The centers were super sharp. AF works perfectly when changing what part(s) of the frame are being metered. The edges of the photos were very clear. Not razor sharp, not overly soft. Once again more than acceptable for wide open non "L" or "Art" glass. I will be taking the lens out tomorrow to see what shots at f/8 look like. If they get sharper than what I saw at f/4, this lens will be great and I have no reason to think it won't be. Based on what I saw in the house, its a keeper.I do plan on switching to full frame. At that point, I'll step up to "L' glass but will keep this lens in my travel bag. This kit from Digital Goja was received in perfect condition and as promised. The included extras make this a great value.

Fits perfect on my 70-200mm 2.8 L lens and 24-70mm 2.8 L lens.

This polarizer is being used on a Canon EF 70-200mm f/4 L IS USM Lens. It removes glare from water and darkens the sky as it should. I don't see any problem with this polarizer.

About a year ago I bought the EF 70-300mm f/4-5.6 IS USM lens. At the time, it appealed much more to me than its (more than three times the price) "big brother" - the lens did well for me but left me wanting MORE! I just got this lens, EF 70-200mm f/2.8L IS USM. It is worth every penny - those of you who have used an IS lens before will know what to expect in that regard, however if you have never owned a lens with canon's "L" glass, you are in for a treat! The color and image quality are far above the cheaper canon line. And the fixed f/2.8 is a fantastic advantage to have. I do mostly indoor concert photography and this lens has been a dream come true. (i know that sounds lame... check one out and you will see what I mean.!) If the fixed f stop isn't that big of a deal to you, im sure the f/4 is probably a good lens as well....however I can definitely say that this was a smart buy!

The Canon EF 70-200mm f/2.8L IS USM Telephoto Zoom Lens is nothing short of incredible. I'm using it on my Canon XTi. With the XTi's multiplication factor of 1.6 the effective focal length of this lens is 112mm to 320mm. The thought of a 112mm to 320mm lens which features a maximum aperture of f2.8 throughout its range and has image stabilization is hard to comprehend at first. After a couple weeks of use, I find this lens is fast, sharp, quiet, and a bit heavy. This lens is fantastic for portraits. It's also great for close-ups taken from about 5-6 feet away. It's far more versatile than I expected.
