Samyang recently released new firmware for a large number of its autofocus lenses. The update is specifically intended to improve compatibility with the Sony α7 V (a7M5). It focuses on better communication between Samyang lenses and the Sony A7 V, with more stable autofocus (AF-S), more reliable lens operation, and improved overall performance on this relatively new Sony body.
In addition to targeted optimization for the A7 V, the update also provides a general improvement in the stability and reliability of Samyang autofocus lenses, which also benefits users of other recent Sony cameras.
Why this update matters
The Sony A7 V is one of today’s most important hybrid full-frame cameras and is popular with photographers and filmmakers alike. There had been reports and discussions that some third-party lenses, including Samyang models, initially performed less consistently on this camera, particularly because of communication and firmware differences between lens and body.

The new Samyang firmware brings a clear improvement. For Samyang FE users, this means greater stability, more reliable autofocus, and smoother operation with the Sony A7 V—making the update relevant to the Dutch Sony community as well.
What exactly has been improved?
Samyang states that the firmware primarily improves communication stability between lens and camera, with particular attention to:
- Better AF-S performance
- More reliable lens control
- General performance optimization on the Sony A7 V
In practice, this should mean fewer error messages, more consistent focusing behavior, and more stable operation, especially during rapid autofocus actions and video recording.

The Samyang update is part of a broader development in which third-party lens manufacturers are increasingly adapting their firmware to new Sony cameras. Other brands have also recently released updates to resolve compatibility issues with the A7 V. For users, this means the Sony FE lens ecosystem is becoming more stable and reliable, whether they use Sony, Samyang, or other brands.
