Sony has today released a firmware update for the Alpha 7S II that is designed to eradicate the occurrence of a black spot it says may appear in photos.

In a statement about the Alpha 7S II, Sony UK said: ‘It is designed to eliminate the occurrence of a black spot that may appear in frame when shooting in a specific set of high-intensity light conditions.’

The version 1.10 firmware is available to download via the Sony website.

The full-frame Alpha 7S II was announced in September, priced £2,500.

Features include a top ISO of 409,600 and 4K video.

The camera, which boasts a shutter cycle of 500K, was announced at the IBC broadcast technology show in Amsterdam, the Netherlands.

The 12.2-million-pixel Alpha 7S II is designed to shoot 4K video with full-pixel readout and ‘no pixel binning in full-frame format’. This should mean better image clarity.

Sony also upgraded the AF to offer 169 AF points – for ‘fast, precise focusing with greater accuracy’.

The firm claimed at the time: ‘When shooting video, the AF performance is twice as fast as the predecessor.’

The EVF was also improved, to deliver 0.78x magnification.
