Prior to lớn the Canon EF 70-200milimet f/2.8L IS II USM Lens being introduced,the Canon EF 70-200mm f/2.8L IS USM Lens was my favorite và one of my most-used lenses.

Combining a very popular và very useful focal length range with excellent image quality, professional build quality,superb autofocus performance, a fast aperture & one of my favorite features - Canon"s valuable 3-stop Image Stabilization -makes the 70-200 IS one of Canon"s most desired lenses.When I really need lớn make every shot count, the 70-200 IS is one of the first lenses I will include in my bag.It is one of the most-professionally-used lenses available & finds a home page in the kit of many, many serious amateurs as well.

Like all of the Canon L Series Lenses, the Canon EF 70-200milimet f/2.8L IS USM Lens" build unique is very high.High build chất lượng often results in a form size & weight penalty.

Weighing 3.24 lbs (1470g) and measuring 3.4" x 7.8" (86.2mm x 197mm), the 70-200 IS will not be mistaken for a light or small lens.However, I can carry this lens for long periods of time without feeling it is a burden.This is a weather sealed lens that is ready to lớn take professional use (or should I say "abuse").

The Canon EF 70-200mm f/2.8L IS USM Lens balances out great build quality with excellent image quality.Images are sharp wide open (f/2.8) - corner performance is remarkable even with a Full Frame body.Stopping down lớn f/4 delivers even sharper results with better contrast.

I have received some comments on the ISO 12233 resolution chart samples for this lens - some think they are too soft at f/2.8.As I get time, I redemo questionable results - Or even buy another copy of the lens to insure accurate but expectable results.I re-tested this lens and the Canon EF 70-200mm f/2.8L non-IS USM Lens at the 200milimet focal length using AF, MF and bracketing - obtained results were identical.The chart is tough on optical performance, & real life images bởi vì seem sharper.I use this lens wide open much of the time - the results are quite satisfactory to lớn me.Stopping down from f/2.8 lớn f/4 will show a difference - & will make this lens very cchiến bại in performance lớn the remarkableCanon EF 70-200milimet f/4L IS USM Lens at the same aperture.

màu sắc và contrast are good.Some CA is present (especially in the upper focal lengths).Vignetting is well controlled, basically only showing in the corners at f/2.8 và encroaching the most at 200milimet. I notice slight barrel distortion at the 70-200"s widest focal lengths full frame body toàn thân.Distortion is not an issue with a 1.3x or 1.6x FOVCF toàn thân.

Utilizing an 8-blade circular aperture, the Canon EF 70-200milimet f/2.8L IS USM Lens delivers foreground/background blur chất lượng that is renowned.It doesn"t get much better than this.The longer included focal lengths will create a diffuse background blur as well.

The Canon EF 70-200milimet f/2.8L IS USM Lens delivers fixed focal length lens performance in a much more versatile (in my opinion) package.Use the included ISO 12233 Resolution Test Chart sample crops khổng lồ compare the 70-200 IS with some of the fixed focal length lenses in this focal length range such as theCanon EF 135milimet f/2.0L Lens& the Canon EF 85mm f/1.2L II USM Lens.The primes have sầu some advantages (a wider aperture is one of the biggest) và I use them, but the versatility of 130 other instantly-available focal lengths causes me khổng lồ far more frequently use the 70-200 IS.Having zoom versatility can mean the difference between getting the shot & getting nothing with a young, energetic child.Any cropping required on a picture shot with the prime will quickly negate any image unique advantage it has.

The Canon EF 70-200mm f/2.8L IS USM Lens" internal focusing is very fast, quiet & accurate thanks in part lớn Canon"s excellent Ring USM (Ultrasonic Motor).An autofocus range limitation switch enables enhanced autofocus performance.Aside from a very slight amount of play in the focus ring (not enough lớn impede manual focusing),the zoom & focus rings are very smooth & nicely sized.The objective sầu lens does not rotate or extkết thúc with focusing (or with focal length changes).

Canon"s excellent Image Stabilization (IS) allows the 70-200 IS khổng lồ be handheld in 3 f-stops lower light level than the non-IS Canon 70-200 f/2.8L USM Lens. I can handhold this lens at 200mm with a shutter tốc độ as low as 1/30 và maintain a decent hit-rate whereas the non-IS lens would require a shutter tốc độ of at least 1/200 to yield similar results.

The included Mode-2 IS is designed for panning.Use it for a subject moving in one direction - pan the camera with the subject.Good subjects for Mode-2 IS include a bicycmenu or a vehicle.Blur the background with motion - leave sầu the subject sharp with good depth of field.

This IS version is tripod-sensing - The Canon EF 70-200mm f/2.8L IS USM Lens knows that a tripod is being used when vibrations go below a certain cấp độ.Keep IS turned on when mounting on a tripod to take advantage of this secondary IS mode - reducing mirror slap, shutter and tripod vibrations.The downside is the slightly additional battery drain.

Keep in mind that Image Stabilization will not stop subject motion.Moving subjects such as a running soccer player will require higher shutter speeds (or a bright flash) khổng lồ stop the action - Image Stabilization does not help in these situations.Many people question the additional cost of the IS version of the 70-200 f/2.8.My advice - unless you are only shooting fast action or in bright lighting conditions, go for the IS version.

With a relatively long closest focus distance of 55.1" (1400mm), the 70-200 IS is not going to lớn be confused with a macro lens.A maximum magnification of .17x can be a limiting factor for very tight portraits with this lens on a full-frame body.Of course, extension tubes can help - taking the maximum magnification to .22x & .41x for 12milimet and 25milimet tubes respectively.The maximum magnification at 200mm is actually less when extension tubes are used (.06x và .14x) than when they are not present.Native sầu maximum magnification is achieved at 200milimet.

A tripod ring, a lens hood và a nice lens case are included in the box when the Canon EF 70-200mm f/2.8L IS USM Lens purchased from a reputable retailer.With a 77milimet filter form size, it is easy to lớn mô tả filters across Canon"s L lens series zooms.

I find MANY uses for my Canon EF 70-200milimet f/2.8L IS USM Lens, but portrait photography is where this lens shines for me.I would choose the 70-200 IS over everything else if I were going to take out-of-the-studio portrait pictures - especially candid portraits.Some may find the 70-200mm focal length slightly long on a 1.6x FOVCF body,but this lens would still be my personal choice.Image Stabilization lets me take indoor daylight-lit portraits without additional lighting (with a still subject that is).

Outdoor sports photography is another popular use for the Canon EF 70-200milimet f/2.8L IS USM Lens.I say outdoor sports because f/2.0 or higher is often required khổng lồ achieve sầu a high enough shutter tốc độ khổng lồ stop indoor sports action.If the 70-200 f/2.8L IS is what you have sầu, definitely use it for indoors sports. You will likely need to lớn use ISO 1600 or 3200 to stop the action.Of course, if your indoor sports lighting is exceptional, this is the perfect lens lớn use.

OK, baông xã outdoors ...The 200mm maximum focal length is fine for even the big field events if you are using a 1.6x FOVCF body toàn thân and/or a Canon Extender EF 1.4x.More serious field sports (soccer, baseball ...) photographers prefer even longer focal lengths such as those available in theCanon EF 100-400milimet f/4.5-5.6L IS USM Lens -is a very good alternative for this use.While the pros often shoot these sports with a Canon EF 400mm f/2.8L IS Lens,they frequently have sầu another camera toàn thân with a 70-200 IS mounted on it for the closer action.The wide f/2.8 aperture availability can be a big help for those early morning, late evening or heavily overcast events.

Going for a walk in the park or to the beach with the family?The 70-200milimet focal length is great for candid shots of the loved ones.Some think the 70-200 IS weighs too much for this use; most don"t mind the weight after seeing their results.

The Canon EF 70-200milimet f/2.8L IS USM Lens is frequently employed at weddings.Lack of light is generally not a problem at outdoor weddings, but indoor weddings (& receptions) are usually light-challenged.There is not a lot of action (movement) during most wedding ceremonies and IS can be very helpful in this situation.The 70-200 zoom range lets you take a variety of shots without intruding on the ceremony.Capturing unsuspecting subjects results in more-candid shots.

Indoor church and stage performance photography can be a great use for the Canon EF 70-200mm f/2.8L IS USM Lensas long as the subjects are not moving too much.Indoor & outdoor event photography is another great use.

General wildlife photography is another area where my Canon EF 70-200milimet f/2.8L IS USM Lens finds occasional use.When paired with the Canon Extender EF 1.4x II on a Canon body with a 1.6x FOVCF, this lens starts having some significant reach.If you plan to lớn use this lens with an extender most of the time, I once again suggest you look at theCanon 100-400milimet f/4.5-5.6L IS USM Lens or theCanon 300milimet f/4.0L IS USM Lensas performance with the 1.4x is decent but not exceptional.The 70-200 f/2.8L IS is also compatible with theCanon Extender EF 2x II,but not everyone will be satisfied with the results of this combination.

The Canon EF 70-200milimet f/2.8L IS USM Lens is not an inexpensive sầu lens, but it is very worth the price in my opinion.I considered this my second most important lens with the first being a more general purpose lens in focal length range.My keeper rate from this lens is among muốn the best of any lenses I have sầu used.
