Awesome lens The clarity I get on action shots in low lighting for hockey is amazing. You can clearly see image frozen facial expressions and clarity from over 200 ft.
THE 70-200mm standard! Great lens. Sharp. F2.8 throughout its range. Fast autofocus.
Sharp Wildlife Lens This is a sharp lens, especially at f/8 its sweet spot. It is considerably sharper across all levels compared to the Tamron 150-600mm. The weights are about the same. It has considerably less chromatic aberration than the Canon 75-300mm whether the cheaper stm or the USM IS version. This is great when shooting great white egrets in the sunlight. It is sharper than the old glass canon 70-200mm with an old 1x teleconverter. The autofocus is not as good as the canon 75-300mm even if you use the setting so that it does not have to use the full range. Consider fine-tuning your focus tracking and lock settings to be less sensitive when there is a busy background or with birds in flight to help avoid back or front focusing. But when it does not back or front focus or you are spot-on with manual zone focusing the results are spectacular for wildlife including hummingbirds, ospreys, cat birds, wax wings, jays, squirrels, deer, pelicans... The IS works well on all three settings 1-3. Read full review
