Sony is adding three new fixed focal lengths for full-frame cameras to its G lens series: the FE 50 millimetre F2.5 G (model name SEL-50F25G), the FE 40 millimetre F2.5 G (model name SEL-40F25G) and the FE 24 millimetre F2.8 G (model name SEL-24F28G).
As is typical for primes, all three lenses have the same size (68 x 45 millimetre diameter), the same filter diameter of 49 millimetres, almost the same weight (FE 50 millimetre F2.5 G: 174 grams, FE 40 millimetre F2.5 G: 173 grams and the FE 24 millimetre F2.8 G: 162 grams) and internal focusing. This makes them easy and quick to exchange without changing the configuration of a rig - for example when using a gimbal.
The FE 50 millimetre F2.5 G offers a minimum focus distance of 0.35 metres (AF) / 0.31 metres (MF) and a maximum magnification of 0.18 (AF) / 0.21 (MF).
The FE 40 millimetre F2.5 G has a minimum focus distance of 0.28 metres (AF) / 0.25 metres (MF) and a maximum magnification of 0.20 metres (AF) / 0.23 metres (MF).
And the FE 24 millimetre F2.8 G has a minimum focus distance of 0.24 metres (AF) / 0.18 metres (MF) and a maximum magnification of 0.13 (AF) / 0.19 (MF).
All three lenses have a focus hold button, focus adjustment switch, aperture ring and aperture click switch. Via the camera menu, the user can customise the focus hold button and assign an alternative function to it. The aperture ring is said to offer a more direct and intuitive feel when filming than when setting the aperture via the camera. In addition, the aperture ring is equipped with a switch that can be used to activate grid steps or - for smooth aperture changes during video recording - to deactivate them.
The aluminium exterior parts are not only designed to increase stability and durability, but also support dust and moisture resistance.
Last but not least, all three lenses are equipped with two linear motors that are supposed to support a fast and precise autofocus (AF) with excellent tracking behaviour. This is to make them explicitly suitable for capturing moving subjects. The AF operation is also so quiet that filming is not disturbed.
Each of the new G lenses will be available from April for 699 euros (RRP incl. VAT).
