Sigma 200mm F2 DG OS | Sports

Early reviews describe it as extremely sharp from f/2 to the edges, with clean, creamy backgrounds and very little longitudinal CA. Testers point out that it costs a fraction of the old DSLR 200mm f/2 lenses from Canon and Nikon while matching or beating them optically. The stabilisation and AF tracking are rated suitable for indoor sports and events.

The reservations are practical ones. It is heavy and conspicuous, it does only one focal length when a 70-200mm f/2.8 covers far more, and the 1.7m minimum focus distance limits close portraits. Sigma's teleconverters work only on the L-Mount version, so Sony users cannot extend it.

Owners who shoot portraits, court sports and stage events say the look at f/2 justifies carrying it, and that the OS makes handheld use realistic. The tripod foot as a handle and the aperture ring get positive mentions.

The main complaints are weight on long days, the attention the white barrel attracts, and the price for a single-focal-length lens. Some Sony shooters regret that the L-Mount teleconverters are not an option on E-mount.
