Canon EF 70-300mm f/4-5.6L IS USM UD Telephoto Zoom Lens for Canon EOS SLR Cameras

After using numerous rental units of various specs and Quality, I found the perfect lens. Light weight and powerful. Great lens to start my future hobby/ business.

Ordered a week ago and arrived the 2 days ago, and a day before my birthday. Decided to snap some scenery pictures around my apt complex to take for a test drive, and the clarity of this lens is phenomenal!! The color contrast and focus is superb compared to the standard IS lens. I am already excited to do more with this lens in the days and weeks to come, as well as doing action shots testing focus and zoom capabilities in the near future. If you're looking to update your lenses, this is a go to lens that does great and being only about 3 lbs, you won't notice or tire easy from use. Pictures attached to show clarity of lens with color and focus is borderline HD quality.

I was looking for a quality zoom lens with a good stabilizing feature and this lens absolutely meet that expectation.

I bought this lens in 2013 and I have not been disappointed in the quality. I damaged the front element two years ago and had it replaced and calibrated and now it is sharper than ever. Image quality is fantastic and the speed of focusing is faster than the 100-400mm F4.5-5.6L IS II that I rented to test on my 7D Mk II. Two things disappoint: 1) It can't be used with one of the canon extenders and 2) no tripod collar, which would be very useful when used on a monopod for better balance. Overall the 100-400mm provides more reach and is slightly sharper. A great first L series telephoto zoom.

I was looking for a "walk-around" L lens with the focal range provided by this lens but not as large as my 100-400 L and settled on the EF 70-300mm. Thus far it has worked well: sharp and relatively compact. It is heavy but manageable. Highly recommended.

Not yet used to this new lens to give a real review. Did a few test comparisons between my present 70-300mm EF IS USM lens and there is a noticeable improvement in sharpness as well as colors being better defined. I was pleased to find that this 70-300 fit perfectly in the partition the earlier lens took in my camera bag. Will take a bit to get used to the increased weight. Goes well with my 24-70mm EF L purchased last year from Canon.

I've had my lens for just about a year. All the shots I've taken have been hand held. I love this lens. I own the 70-200 f/4 L IS, the 200 f/2.8L prime, and this one is sharper than both. Just got back from a whale watching trip, this lens focused very fast, and I was able to shoot several 10 frame bursts with my 1DX mkii, all in focus and tack sharp. This is one sick lens, wouldn't let go of this for anything. It's not a fast lens, but worth every penny.

Great lens. Shot in a covered bridge and not enough light. Had to switch to my f2.8 70-200mm. But, I’m sure outdoors and for sports it will be great. Next assignment is in two weeks.

This is the first high-end lens I have owned and so far I love the picture quality I get from it.

I wish Canon would make their L lenses for pro's. It's a nice range to work with for nature, but please give me a fixed f4 throughout. The 100-400 makes this lens irrelevant They already have other variable aperture lenses suitable for amateurs. Canon: you can do better!

I shoot a lot of motorsports - 30 events a year on average. In the old days, a 70-200 was considered the "normal" lens for track-side work. Safety concerns have pushed us further and further away so we need the reach of a 300mm on a crop-sensor camera to get the kind of shots editors want. I have the wonderful 100-400 lens and instead of upgrading my 70-200 to get the IS technology I love, my Canon rep suggested I try this lens for reach, excellent optics and compact size. I made the decision to follow his suggestions and I'm very pleased I did. The 70-200 sits in the camera bag now for super low light assignments and I use this lens on the 7D Mk II and the 100-400 on my 5D Mk III for most race days. It's a rugged, weather sealed winner for what i do. Yes, it's a little slow but the high ISO capabilities of my Canon bodies, for practical matters, puts that concern to bed for me.

This is my first L lens that I own! (I rented the amazing 50mm L f/1.2 before) I previously had the non-L 70-300mm version and also have the 55-250mm STM (I shoot with 80D). This lens beats them both, and by a lot! The colors are so much richer, and bokeh is a lot better than with 55-250. Also it is very sharp. I had to microadjust the focus a bit but not by a lot, now it's spot on. I got a refurbished lens but it looked like new.

I've had this lens for 5 years now and shoot with it on a crop sensor (7D MkII) body. It has a lightning fast focus and great range. I dropped it and had it repaired and calibrated by Canon I like it too much. Now it is as new and sharper than before.

I shoot this on a crop body (7D M2). It's sharp, fast, and a pound lighter than the 100-400 It's close focusing makes it great for flowers, put tubes on It and you have the ideal macro. A real winner

I bought this lens after doing a lot of research on telephoto zoom L series. Compared to the celebrated 70-200 f/4 L IS, or 70-200 f/2.8 L IS, this lens is not that popular. I wondered why! However, I got a good deal and bought it. I would never regret my decision. This is one of the sharpest lens that I have used. The zoom range is good for almost anything, wich makes it a perfect travel lens. Here are the Pros and Cons. Pros: 1. Perfect weight for handheld photography. No need for tripod. I use it for all day shooting on my 6d. The weight grows on you. 2. Excellent for portrait. The range between 100 - 150 is very sharp and you have the max f/4 limit, making creamy bokeh possible. 3. Sharpness at 300 mm. 100 crop at 300mm can beat other lenses (I compared with a 150-600mm from another maker). So if you are thinking of buying a longer lens but don't have all the cash, try this one! 4. Versatile: Takes decent landscape, excellent portrait and above expectation wildlife and nature photographs. Can't et any better. Cons: 1. Tracking moving object: Little slow in AI Servo mode - tracking is decent though. Maybe I will buy a 400 f.5.6 for that. But remember this is not supposed to be for BIF but I could take some decent BIF pics with practice. 2. Tripod Ring not included in price. See Pros. #1. I actually have it but never used it! Might be helpful if I decide to take the solar eclipse picture. Do you really need it? 3. Focusing ring placement: Some people say it's an inconvenience. I am just writing it here to reiterate - it's no big deal! The pros outweighs te cons many times over!

I shoot portraits, body shots for press releases. I love this lens. I'm mainly outside on the beach so the 4-5.6 doesn't bother me. My favorite lens.

I purchased this lens as a refurbished product. Pricewise it was a great bargain as Canon had further 10% off. It came with Lens, both Caps, Hood and Case. The box came with was not original lens box. Product had no scratches, marks or any visible sign showing that is used or so. It was looking like a new one. Lens build quality is a amazing, built like a tank. I have taken several shots so far and image quality is excellent as it should be in L lens. But I would say it is very little soft on wider side than telephoto. Image stabilization works awesome on this lens. Even at telephoto end it quickly stabilizes the image as soon I press AF or shutter button and I can click the shot. Lens is bit heavy at 1050 gms. I use Canon 80D which gives me focal range on this lens from 112-480mm. Earlier I had bought Canon 70-200mm f/4 L Lens non-IS, but image quality did not seem to be on par with the L tag even in bright light. I was surprised and returned it. In comparison, this lens is amazing. I plan to use it to shoot wild life, birds and maybe sports. Overall I am very with the product.

Yes this is a "lens" review. ... and the lens is performing well. However, owning some 20+ Canon lenses including 8 that use lens collars, this is the FIRST lens collar that is poor. Sure I know it "can" be shot without one. However, for serious landscape photography, I believe the better balance adds to stability and convenience, especially when shooting vertical. Two things: The bolt does not completely tighten down the spinning movement. More importantly, the lens actually rocks in the collar.

I bought this in 2012, replacing my EF 70-200mm F/4L IS w/1.4 extender. It covers the range most useful to me without adding and removing the extender. Focus speed, image stability and clarity are exceptional, used mostly for birds and wildlife. My daughter loves it so much she is now taking it on an African safari with her family, willing to deal with its size and weight on a complex trip.

I am an amateur photographer and I was looking for something with a little more zoom and quality than the lens that came with my camera. I have taken the same exact shot with both lens' and this one is a way better quality image.
