Viltrox Confirms Sony Did Not Intentionally Brick Third-Party Lenses on the a7 V

In Australia at: Camera Pro, Sony Australia.

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.

Haters Silenced: Bill Claff reevaluates the measurements and confirms that the Sony A7V is the King of dynamic range!

Bill Claff from PhotonsToPhotos re-ran the Sony A7V evaluation— and guess what? The dynamic range numbers are still jaw-dropping. At low ISO, the A7V rivals medium-format monsters like the Fujifilm GFX100 II and Hasselblad X2D II, beating the entire Sony Alpha lineup in the process.

So much for the claims that the A7V was “cheating” when the earlier results included noise reduction. 😏

Here is the Sony A7V vs the Sony A7IV (note: mechanical shutter used):

As on any camera if you use electronic shutter dynamic range drops:

And here is the comparison with the nearly 3 times more expensive medium format cameras:

This is now the PDR ranking from Bill Claff:

What can we say… this looks like a clear winner. I highly doubt the Canon R6 Mark III will come anywhere close once Bill finally tests it. 😏
