For Canon users, the Canon EF 70-200mm f/2.8L IS III Lens will likely be at the top of the considerations list. Testing the lens under ideal conditions, using an ultra-high resolution Canon EOS 5Ds R, most of my 70mm images were sharp at 1/6 second exposures and about half were sharp at 1/5 second with a strong taper off in keeper rate at longer exposures.The not yet released Tamron SP AF 70-200mm 2.8 Di VC USD: The cheapest listing of around 1600 EUR certainly is not a real street price yet. is heavier (63.5 vs. 53.0 oz, 1800 vs. 1500g w/ tripod ring), has a larger diameter (3.71 vs. 3.48", 94.2 vs. 88.5mm), takes larger filters (82mm vs. 77mm) and features slightly shorter focus and zoom ring rotations.

Manual focus is also possible, as is Manual Override (MO). With this latter feature, the user is able to continue using autofocus as normal, before making any final manual adjustments using the focusing ring around the lens. This is particularly useful when capturing moving subjects, which may move slightly just prior to capture. Looking at the Sigma 70-200 Sports vs. Canon 70-200L IS III specs comparison, we find that the Sigma lens has more aperture blades (11 vs. 8), is larger, From Sigma lens literature) This telephoto zoom lens has a large maximum aperture of f/2.8 which remains constant throughout the zoom range and it is optimized for digital SLR cameras. Two pieces of SLD (the special low dispersion) glass in the front lens group and another two in the rear group offer excellent correction of chromatic aberration. High optical performance is demonstrated throughout the entire zoom range.
A lens of this size and weight creates a significantly-front-heavy situation for a tripod-mounted camera.
