Of course that never will happen.

That would result in big trouble with Sony. Viltrox is not crazy to risk that.

Highly doubtful. They’d have to likely spoof some sort of identifier in the code that tells the camera it is a legit Sony lens or not… pretty sure Sony has a far more well funded legal team the Viltrox.

Nope, TC and lens limitations are separate but still, I'm surprised that Viltrox made a TC for Sony and Nikon while supports 120 FPS on some GM lenses cause TC itself is NOT allowed.

Well, unlike Sigma and Tamron, Viltrox and Chinese companies are not under the legal contract instead of reverse engineering their technology like DSLR era. Even if Sony has a legal team, it wont work and affects any Chinese companies as they are well known for ignoring legal problems such as Leofoto. That's why Sony A7V had issues with Chinese lenses recently as they are not officially licensed with Sony.

Besides, Viltrox's TC itself already a huge problem which against Sony's 3rd party policy.

Canon has already stopped some Chinese lenses. So I'm sure Sony can too.

Also note that the pics Viltrox posted showing little degradation of IQ were shot on the A7C2. I would wait till real reviews with 50-60MP cameras come in to make any judgement.

I have to wonder if Sony is gonna block Viltrox TC or not cause if they allow it, then Sigma can make one too especially since Sony does not allow 3rd party TC especially with 120 FPS + AF-C.

Yawn. So essentially the same as a Sony TC, only cheaper and with additional compatibility to the Viltrox 135 (which no one uses anyway). Now THAT'S a boring product 😅

Could this work with Tamron 150-500mm? That would make one happy camper...

Cheers, A.

Performance with the 135 LAB lens seems quite bad.

Performance with Sony GM's seems to be on par with Sony's TC, but with less spherical glow?

Someone from Facebook tested with Sigma 300-600mm F/4 and it works.

I mean, it being 1/3rd of Sony's price doesn't seem very irrelevant to me

Thanks for the feedback. Do you still have the Sony TC 2x for comparison ? On which lens was it tested ?
