At the A7 V launch, Kai discovered a few of his third-party Chinese lenses weren’t behaving correctly on the new body. That sparked instant speculation that Sony was deliberately hobbling third-party glass. Nope. As I said right away, this wasn’t a targeted lockout.

Petapixel reports a message from Viltrox:

Nothing we’ve seen so far suggests any intentional behavior on the camera side. This appears to be part of the normal post-release optimization that often occurs as new camera systems are introduced, It’s fairly common across the industry for lens firmware to be fine-tuned after new camera bodies are released, as manufacturers validate performance across a wide range of real-world scenarios.

Bottom line: the “conspiracy” a few were pushing was exactly that—baseless.
