Professional users of mirrorless Sony cameras can finally complete their arrays with a new bright FE 400mm f/2.8 GM OSS lens which has been announced for a long time.
The lens has been designed having in mind sports photographers as well as the ones wanting to catch wildlife in movement – the combination of the above in the form of, for instance, a bear on a skateboard is, of course, possible.

The optical system of the new Sony lens is based on 23 lenses placed in 17 groups, 3 of which are low-dispersion fluorite lenses. In order to ensure good balance of the lens, the lenses have been placed in the central and rear parts of the system. The lenses are covered with anti-reflective and fluorine coatings, which enable keeping them clean.

The lens is equipped with a 11-blade aperture. Two newly-designed linear motors, which are supposed to facilitate the tracking of moving objects, are responsible for the functioning of the autofocus. At our disposal, we have 3 modes of image stabilization and a sharpening clutch. On the side of the lens, we have function buttons, including Full-Time DMF switch, which enables continuous manual sharpening.

One of the main advantages of the lens is its construction. It has the dimensions of 158 × 359mm, it weighs only 2.7kg and it is supposed to enable, in special circumstances, photographing ”from hand”. The lens is made of magnesium and is, of course, sealed. Inserted filters with the diameter of 40.5mm can be used on the lens. In the case of using 1.4× and 2× converters, the brightness will decrease by, respectively, f/4 and f/5.6.

Sony FE 400mm f/2.8 GM OSS will appear on sale in September. The enthusiasm may be cooled down by the price of the lens since, as at today, it will cost $12,000.
