Further readings for the Sigma 120-400mm F4.5-5.6 DG APO OS HSM Nikon
To provide photographers with a broader perspective about mobiles, lenses and cameras, here are links to articles, reviews, and analyses of photographic equipment produced by DxOMark, renown websites, magazines or blogs.
Aimed at professional studio and landscape photographers, the full-frame 36-Mpix D800E with its modified AA filter effectively increasing resolution over the standard D800 model is the closest 35mm full-frame camera yet to rival larger formats in rendering fine detail. If you’re undecided over which of the two models to choose, we’ve analyzed the image quality of the Nikon D800E with over 100 different lenses to discover how well this groundbreaking camera performs.
Nikon has had an 80-400mm lens in its range for the past 13 years, which it has now updated. This is not just a bit of a tweak though; the new lens is sharper, better corrected for distortion and chromatic aberration and full of new technology. It is also heavier, bigger and more than 50% more expensive – so is it worth it?
The Sigma 120-400mm f/4.5-5.6 DG APO OS HSM is interesting for its longer focal lengths, equivalent to a 180-600mm on a Nikon DX body (and slightly more on a Canon APS-C). On a full-frame camera, it achieved a respectable DxOMark score of 15.8 though it dropped to just 11 on a Nikon D7000 (a slightly higher than on a D300s). Highpoints, apart from the extra reach, include consistent resolution across the image field (the Acutance map above shows the lens at 400mm), as well as good control of chromatic aberration, while the disadvantage of vignetting at maximum aperture is really only an issue for FF bodies. While not as pricey as some, $1,000 is still a sizeable figure given the performance at 400mm.
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.
How come that some lenses such as the Sigma 120-400mm, launched in 2008, still are not reviewed and do not appear in the lens rating chart while, in the same time, recently launched lenses are already reviewed?
