New free firmware update for 13 Sigma lenses fixes issue when used with recent Sony camera

Sigma 20mm f/2 DG DN.

Sigma has released free firmware updates for 13 Sony E-mount lenses, bringing compatibility improvements for photographers using the new Sony A7 V.

The rollout covers a range of Contemporary and Art primes, including six of the company's premium I Series lenses.

While the firmware versions vary between Version 3 and Version 7 depending on the lens, they all deliver the same fix: resolving a rare issue that could cause the camera's monitor to black out and freeze during shooting when paired with the Sony A7 V.

Firmware

Updates: 17mm, 20mm and 24mm

If you caught Episode 4 of Bokeh Face: Digital Camera World podcast, above, we discussed the best time to install firmware updates, why they matter, and what issues they can cause. It's a helpful listen if you're unsure when – or whenever – you should update.
