Our friends and collaborators over at DxOMark have recently been looking into how lenses score on specific cameras, and the latest model they’ve examined is the Nikon D600. In a three-part article published at the end of last week, they investigate how 70 lenses from Carl Zeiss, Nikon, Samyang, Sigma, Tamron and Tokina measure up on the D600’s 24MP sensor.  The article also compares how given lenses score on the D600 compared to the 36MP D800 and 24MP D3X. Click through for links to the three parts of the article.

DxOMark investigates lenses for the Nikon D800

14 Mar

DxOMark has tested 61 lenses on the Nikon D800, and drawn some conclusions about the results. So far it has published two sections of an eventual four-part article: the first discusses how much benefit the D800’s 36MP sensor really offers over the 24MP chips in cameras such as the D3X and D600, while the second looks at which lenses in the 50-100mm range come out with the best DxOMark scores. Further parts later this month will look at telephoto and wideangle lenses. Click through for the link.

Lensrentals’ Roger Cicala has published the third part of his investigation into Canon’s autofocus systems, looking at what’s changed behind the marketing claims. It’s not unusual for manufacturers to promise that their products are ‘new and improved,’ but explanations about what’s been changed or how much of an improvement it offers are harder to come by. Cicala has delved into Canon’s patents (and taken some lenses apart), to see exactly why the EOS 5D Mark III’s focus so consistently out-performs its predecessors’.
