Sigma 24 70 2.8 sony stabilization manual#
It is a typical value for autofocus lenses but it doesn't ensure precise manual settings. Running through the whole distance scale takes a turn through an angle of 90 degrees.
It moves smoothly, without any slacks and is properly damped. The first one, for manual focusing, is 18 mm wide, its middle covered by rubber ribbing. Further on you see an OS switch responsible for the optical stabilization unit (OS ON/OFF). If you employ it the ring still works even if the autofocus is in the full-time mode. Apart from standard options (the ring still works even if you choose the AF mode) you also get the MO (Manual Overdrive) one. The first one, FOCUS, controls the focusing mechanism mode, with three possible positions, AF, MO and MF. On the left side of the scale is an „A” letter meaning the lens belongs to the „Art” group. Further on you see a distance scale behind a window, expressed in feet and meters and below there are given basic parameters of the lens. The proper body of the lens starts with a smooth, black, metal ring on which you can find a white dot making an alignment with a camera easier, an inscription „017” indicating the year of the launch and another inscription, „MADE IN JAPAN”.

Still it must be said that the inside of the barrel is blackened very well, matted and ribbed too. That movement creates quite a big slit in the rear tube through which you can glance some parts of the interior. The element is positioned on the same level as the mount at 24 mm and it hides inside the barrel about 2.5 mm deep when you pass to the 70 mm focal length. The tested lens starts with a metal mount and a rubber gasket the mount surrounds contacts and a rear element which is less than 27 mm in diameter.
In the photo below we positioned the Sigma A 24-70 mm between the Sigma A 35 mm f/1.4 DG HSM and the unstabilized Nikkor AF-S 24-70 mm f/2.8G ED. The Tokina looks the poorest, with the lowest amount of elements, without any optical image stabilization unit or an ultrasonic autofocus motor. The Sigma prevails in this group when it comes to the minimum focusing distance but still the Sony Zeiss remains unbeatable in this category and it also has the smaller filter diameter. Still the sensible dimensions of the new Sigma are worth noticing - it is notably shorter than the Nikkor, a bit smaller than the Tamron and also smaller than the non-stabilized Canon. On the other hand the Sigma and the Nikkor are most optically complex and the heaviest of all – both weigh a bit over 1 kilo. Only the Nikkor and the Tamron, like the Sigma, are stabilized. The following chart presents a comparison between the tested lens and other 24-70 mm f/2.8 devices. You can change your consents to the use of cookies at any given time.
