Question: Canon 70-200 f2.8 IS Tripod Mounting Ring Does this lens from Amazon include the tripod mounting ring? It does not show or describe it anywhere in the text.Thank you.
Document: What's there to say? It's a Canon EF 70-200mm f2.8L IS lens!!! Shipping with a tripod ring, lens hood, and case, it is a simply outstanding, tack sharp Canon "L" lens; moreover, the Image Stabilization provides a two-stop-plus difference when hand-holding. Those features and its outstanding performance make it one of Canon's most desired lenses -- and my personal experience with it has been excellent.
I bought this lens for shooting softball action in early evening, twilight, and night games. The autofocus is unbelievably quick and impressive. It's important to remember to set it to IS mode 2 during action. I forgot a few times and the images were not clear enough. The zoom ring is smooth and is conveniently placed. I chose this over the 80-300 mm because the 70-200 got better ratings regarding picture quality and it has the f/2.8. The range of 70-125 is great for infield and shallow outfield, but beyond that it needs to be on a tripod or monopod.
Pros:- Outstanding sharpness, saturation, and bokeh- USM AF is fast and quiet- 2 focus range settings- Fast f/2.8 throughout zoom range complements 24-70mm f/2.8L- Image Stabilizer- 2 IS modes: 1 - normal & 2 - panning- Weather sealed- Common 77mm filter among L-series- Front element does not rotate with focus- Non-existent zoom-creep (lens does not extend)- Solid construction and feel- Focus range indicator window on top of lens- Comes bundled with lens hood, tripod collar ring, and standalone lens bag- Well controlled vignettingCons:- Heavy- Expensive- Longest of the 4 Canon 70-200mm'sThoughts:Outstanding Lens!
Not a huge deal, but you would expect more since Canon paid attention to all the small details elsewhere. By the way, this lens is weather sealed. Both the 70-200/4 IS and 70-200/2.8 IS are weather sealed, while their non-IS sisters are not sealed. Note that this sealing is only effective when you have a weather sealed body to mount it on (read: 1D series camera). There is a rubber ring around the lens mount that provides some of this sealing, and the 1D series has the complementary sealing around its lens mount.
I have never seen sharper images anywhere. The out of focus background is velvet and amazing. The biggest problem with that lens, it is super expensive and so darn heavy. The Canon 70-200mm zoom performs reasonably well compared to the fixed 300mm. It is not as absolutely sharp, but that is to be expected with a zoom versus fixed focal length. The out of focus background is nice, but not as velvety smooth as the 300mm. The Tamron just isn't even in the same universe - slower focus, nowhere near as sharp, and much smaller maximum aperture (which translates into less precise and slower focusing even with the 7D).I am in love with the 300mm f2.8.
I bought this lens a few weeks ago and it consistently produces out of focus images at f/2.8 through f/4.0  Amazon was great to work with, and they sent a replacement which turned out to be defective as well. I've shot several hundred images on each, under various lighting conditions, using my 5D Mark II body. The two exaples I evaluated are very poor performers at f/4.0 and wider. One went back to Amazon as defective, another went to Canon for a warranty claim.I hope they can fix this lens, because I really want it to perform as well as some of the better examples of this product out there.If you buy the 70-200 f/2.8 L IS, be sure to test it at wide apperture values while you can still return it.Shame on Canon for a poor quality control process.
Canon makes 4 L designated lenses in 70-200 range. The question often is f 2.8 vs f 4, and IS vs No IS. I found the image quality of this lens fantastic, wide open, even at 200mm. I find for me IS is essential for this focal length, as I am often shooting portraits with this lens at 1/60th to 1/100 of second. The f2.8 allows for a more accurate focusing as well as better lowlight focusing, and of course, one stop of light.
[For unclear reasons this review and all others for the Mark I lens have disappeared, I'm re-posting mine]I purchased this lens about 8 months ago as my first "L" glass - since then I have added the 24-70 f2.8 Canon (without IS) to complete the range 24-200 mm at f2.8. I really can't say enough good things about this lens, though in retrospect I might have bought the 24-70 first as it is a bit more versatile. The build quality is terrific and the IS is VERY helpful especially at the longer focal lengths.
Each and every time I mount this lens on my 1DS mark II camera, I'm falling in love with Photography again. This Lens is super fast auto focus and deliver sharp and crispy images quality even at wide open F/2.8 the IS functioning is all about for my handheld shooting on location without tripod, it works effectively and reliable. I can compare and rate this lens almost perfect like my Canon 85mm F/1.2L but 70-200 IS USM is faster autofocus. With the zoom lens like this shooting on Manual mode is my favorite cause I can make the most beautiful pictures out of this lens.It wasn't true as some previous review said there is a problem with many lenses with serial number of UT08XX or earlier.
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. Thelens 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 theCanon EF 75-300mm f/4-5.6 III USM telephoto zoom.
Answer: It comes with the tripod ring, the lens hood, and a storage bag.
