Following on from our series of selecting the best lenses for the Nikon D800 with its potential for massively detailed images from the 36Mpix sensor, we’ve now turned our attention to that camera’s younger sibling, the 24Mpix D600.
It seems that every passing month brings a new compact camera to the market, featuring a large sensor and the promise of higher image quality than its peers. However, while the sensor is often the star of the show, the lens is just as important and can make or break the performance of the camera. The Nikon Coolpix A is one of this new breed of large sensor compact cameras, and just a few years ago it would have seemed a most unlikely proposition. However, as technology has improved, costs have come down and it is now possible to fit large sensors in small cameras at a reasonable cost, but this does mean the lenses have to improve in tandem or they risk damaging the great work done by the sensor engineers.
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.
Since the launch of the DxOMark website, many debates have arisen about ISO sensitivity: Some manufacturers were accused of cheating, the ISO sensitivity measured by DxOMark was claimed to be meaningless for photographers. The DxOMark team would like to clarify certain points.
For years, lens makers have fought hard to market lenses of wider and wider aperture. Wide apertures (e.g., f /1.4 instead of f /2) but a series of measurement published on dxomark.com cast some doubts on the real benefits, for digitally equipped photographers, of these progresses.
