Sony remove the 15fps limitation now!

Take a look at this: One Facebook (Click here) you see a video of the Sigma 300-600+ Sony TC 2x + Nikon Z8. The Nikon has autofocus and can take continuous shots at full speed. Also Darek Dariuszbres tested the Sigma 300-600m lens on the Nikon Z9 via Megadap Pro and concluded:

An interesting fact is that Sony limits the number of frames per second on some lenses, including the described Sigma, max 15 fps . Similarly, there are no teleconverters, they are only on the L-mount. I think this is a deliberate limitation to reduce competition, only Sony has such a schizophrenia. On Nikon, such limitations do not exist and if I give it 120 frames, that is how much it goes on the discussed Sigma, or some old lens from a century ago.

Sony needs to explain to me why Nikon photographers can enjoy ‘more’ features when using the Sigma E-mount lens on their cameras via cheap third-party adapters, while we Sony photographers have to live with this unnecessary limitation.

I know Sony managers are reading this…so let me be clear: Get rid of this stupid limitation!
