Digital Camera World Verdict

A slight upgrade from the Mk II, the new edition looks pricey. If you want a top-flight 70-200mm f/2.8 lens, the Tamron G2 delivers excellent image quality, has a better stabilizer and comes at half the price.

Not too long ago, we got the new and improved Canon 70-200mm f/4L IS II USM, with a wealth of enhancements and upgrades that include a completely redesigned optical path and class-leading 5-stop image stabilizer.

By contrast, the only obvious difference in the new 70-200mm f/2.8L IS III USM is that, in the UK, it’s about a third more expensive than the previous edition. You could argue that, with the Mk II lens having been such a favourite of professional photographers across the world, there was little room for improvement.
