Excerpt: You cannot be a professional photographer without a high-quality, high-speed telephoto zoom lens. Within the Canon EOS system, three such lenses are available: All of these provide very high image quality. All have ultrasonic motors and allow for full-time manual focus. This article is intended to help you decide among these three lenses.
Conclusion: The Canon 70-200mm F2.8 L IS USM is quite simply an excellent lens, which will reward users with quality images in almost every situation. On full-frame 35mm, sharpness is very good even wide open, becoming excellent corner-to-corner when stopped down. In addition, chromatic aberration is remarkably low, distortion well under control, and vignetting no worse than we'd expect in this class.
Pros: Superb build quality, Highly effective image stabilization, Excellent autofocus and manual override, Consistently high image quality across almost all of the range
Cons: Slightly soft wide open (most notably on APS-C), Average close-up performance, Somewhat susceptible to flare with direct light sources in or close to the frame
Conclusion: For most photographic applications, either 70-200mm f/2.8 lens is an outstanding tool that produces exceptional image quality. Deciding whether to buy the IS lens or the non-IS lens should probably revolve around the photographer's perceived need to have image stabilization. Image stabilization does come at the cost of higher purhase price and slight loss of image sharpness (You won't notice it in most situations unless you shoot predominantly at f/2.8).
Canon EF 70-200mm f/2.8 USM L IS - Review / Test Report
15 April 2008
Conclusion: The Canon EF 70-200mm f/2.8 USM IS is a very good lens but not a stellar one. The resolution characteristic is excellent at 70mm and 135mm but at 200mm it disappoints - more so regarding its price tag. The results are still very good here (just at f/2.8) but when putting things into perspective (e.g. vs the superb EF 70-200mm f/4 USM L IS) the delivered quality is not overly impressive. Based on the performance at 200mm the potential with tele converters seems "limited".
Canon EF 70-200mm f/2.8 USM L IS II - APS-C Review / Lab Test Report
29 March 2008
Conclusion: Some of you may have already followed our full format review of the Canon EF 70-200mm f/2.8 USM L IS II. The lens performed highly impressive here already but it's even better on APS-C DSLRs due to the sweet spot effect ("center" crop) here. The resolution is nothing short of phenomenal for a zoom lens and that's throughout the focal length range as well as across the image field. Lateral CAs are not an issue to worry about either.
Canon EF 70-200mm f/2.8 USM L IS II - Full Format Review / Test Report
15 March 2008
Conclusion: It was about time. The old Canon EF 70-200mm f/2.8 USM L IS (mk I) was a good lens but hardly something to rave about especially when used at 200mm. Canon claims to have the leadership in the tele lens arena and they probably do but so far with the exception of this lens segment. Well, this was then and the EF 70-200mm f/2.8 USM L IS II is now and it corrects this last remaining flaw in the Canon tele lens segment.
Excerpt: The Canon 70-200mm f/2.8 IS offers a lot to professional photographers in terms of rugged design and functionality. It comes in the Canon L series classic white finish and will make any user look more businesslike. We could find no fault with the design and handling. It may not have changed much over the last few years but why upgrade a lens that works perfectly well? There's another reason why this lens is so popular: the autofocus.
Summary: A high-quality, fast medium-range zoom lens that will suit fashion, wedding and portrait photographers.Built like a tank and ultra-responsive, Canon's EF 70-200mm f/2.8L USM lens is a great tool for fashion, wedding, portrait and event photographers and a good match for full frame DSLRs like the EOS-1Ds Mark II and EOS 5D.
Summary: W pewnym sensie podsumowanie jest pocieszające dla fotoamatorów, których
niezbyt często stać na najdroższe instrumenty i którzy mogą cieszyć się z
wyraźnie tańszego i praktycznie pozbawionego wad modelu 70-200 f/4L IS.
A zawodowcy i tak wybiorą f/2.8, bo w wielu sytuacjach takiego światła,
przy tym zakresie ogniskowych, nie zastąpi nic innego.
Pros: świetna jakość obrazu zarówno w centrum pola jak i na brzegu,, dobrze kontrolowana aberracja chromatyczna,, znikoma koma i dystorsja,, niewielkie winietowanie, mały astygmatyzm,, szybki, cichy i bezbłędny autofokus,, bardzo solidna obudowa,, wysoka jakość wykonania,, bogate wyposażenie.
Cons: słaba współpraca z konwerterem,, praca pod ostre światło pozostawia sporo do życzenia.
