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.
Sigma are well known for their accessibly priced models and at just under $1,100 the 150-500mm f5-6.3 APO seems like a promising alternative to the premium offerings from the camera makers. Although one of the older models in the firm’s range now, does it still have what it needs to compete with more modern rivals?
Following our recommendations for the flagship Sony SLT-A99, we’ve had the opportunity to assess the firm’s semi-professional 24-Mpix DT (APS-C) format model - the SLT-A77 - with a sizeable collection of Sony and third-party prime and zoom models to assess image quality. Read onto find out which of these models perform best when paired with the camera.
After evaluating the performance characteristics of lenses mounted on full-frame models such as Nikon D800 and D600, as well as the Canon EOS 5D Mk III, we’ve now had the opportunity to analyze a range of lenses on the Sony SLT-A99. In this concise report, we’ll see how well the combination of Sony’s high-end image sensor and the latest Alpha mount lenses perform.
Announced only in February this year alongside the Sony made Zeiss branded 50mm f/1.4 ZA SSM, the 70-400mm F4-5.6 G SSM II lens is an upgrade to the original silver finish model introduced in 2009. This new lens is said to boast up to 4x increase in AF operation and an improved optical performance (not to mention a new white exterior). Read on to see how well it performs in our labs.
With the vagaries of photographing wildlife, the flexibility of a telephoto zoom would appear to be an attractive solution. However, image quality is often a compromise at the maximum aperture and longest focal length, typically the most crucial settings. We’ve pulled some lens data from our database and put together a round up of popular zoom lenses over the years (and made some comparisons with high performance primes). Read on to find out which models have the best image quality.
