In part 2 of our review of the best lenses for the Sony A99 II, we look at the performance of zoom lenses. More versatile than fixed focal length primes, zoom lenses offer the convenience of multiple focal lengths in a single lens. Image quality isn’t quite as good on a zoom compared to a prime, however, with generally lower lens metric scores recorded in our tests, although some zooms come pretty close.
As an moderately priced full-frame high-speed standard zoom, the Sigma 24-70mm f2.8 seems like a promising option to the far pricier offerings from the camera makers. Read on to find out how well it performs.

Read onto find out which of these models perform best when paired with the camera.

Read on to see how well this revised version performs on the Sony SLT Alpha 99.
