Excerpt: First released in mid 1999, Canon EF 70-200mm f/4L USM has immediately become a choice for many prosumers and professionals alike. This lens replaced Canon's ancient EF 100-300mm f/5.6L, which was also very liked in the photo community. The lens bears 'L' designation and it indeed looks and feels like Canon's many other professional grade lenses.
Excerpt: Because of its popularity, initial copies of the 70-200mm Lens Mug were very hard to obtain - and multiple test copies were definitely warranted for this important product. Five Canon lens mugs, all purchased retail, were tested for this review.
Conclusion: At almost a third of the price of the big brother lens, comparisons are a little unfair. This smaller, lighter, slower version is a very nice lens for the money and produces excellent results. Being that much smaller and lighter, it makes a good companion for some of the smaller cameras in Canon’s line up such as the 20D and the 350D without the price and weight penalty of the top end lens. And you still get L glass into the bargain!
Pros: Great build quality, Good and consistent performance for price, Silent and quick autofocus
Cons: Chromatic aberration on the borderline, Tripod mount not included in the price
Excerpt: At 3" (76mm) in diameter, the 70-200 f/4 is relatively narrow for its 6.8" (172mm) length. I more frequently use larger diameter lenses, so this is one of the 70-200 f/4's instantly recognized features for me personally. It is not a bad thing - just different. I'm sure those with small hands appreciate this feature.
Canon EF 70-200mm f/4 USM L - Review / Test Report
10 November 2007
Conclusion: The Canon EF 70-200mm f/4 USM L is a very harmonic package combining exceptional build quality with an and very even optical performance throughout the range. Adding an EF 1.4x II only results is a slight loss of quality which is remarkable for such a slow speed zoom. And even better the price tag of this lens is amazingly low for what it offers ... or to be precise: what it offer.
Conclusion: Just the number of counted pros and cons (or con) is probably the best recommendation for the tested lens. If someone can afford to spend less than 600$ and wants to have a somewhat handy and indestructible 200 mm lens, it is hard to find a better alternative than the 70-200 f/4L. All of you, who counted on a completely objective opinion and those in love with L-grade lenses, please stop reading this summary now.
Summary: Another member of Canon's f4 zoom lens suite, the EF 70-200mm f/4L USM combines a relatively compact size with light weight when you consider the amount if glass it contains. Consisting of 16 elements in 13 groups, this lens has two ultra-low-dispersion (UD) elements plus a low-dispersion fluorite element to minimise chromatic aberration.[ia] . .
Summary: Det er nok allerede ret tydeligt at Canon EF 70-200mm f/4.0 L USM har overrasket mig meget positivt, og jeg er blevet ret begejstret for objektivet, da det levere skarpe billeder med flotte farver, flot bokeh og generelt en lækker finish.De fleste der overvejer Canon EF 70-200mm f/4.0 L USM vil formentlig samtidigt også overveje Canon EF 70-200mm f/2.8 L og Canon EF 70-200mm f/4.0 L IS USM.
Pros: Billedkvaliteten, Lynhurtig autofokus, Vægt
Cons: Pris, ”Kun” f/4.0, Ingen billedstabilisering
