What 35mm lens adapters dont cause grain at high shutter speed?

Hiy
Was just looking into 35mm adapters like Letus but then saw the grain issue over speeds of about 90th sec... apart from their new most expensive one.

It's strange to me as some of the music videos I've seen online on Vimeo were shot with Letus and they do look like they must have used a fast shutter speed but no grain issue..

anyway I'm wondering if there's a way around this low shutter speed issue when using adapters as I'd like to have my fast motion shots as sharp as possible but also use 35mm primes on HVX200?
 
I can stop down as much as I want, and use high shutter speeds with the Handy35. You have a dial to adjust the spinning speed of the motor. helps immensely.
 
It´s not in the lens, the GG is causing the problem. You need a spinning adapter, vibrating won´t do the trick.

Letus Utlimate can do high speeds, and even has amotor speed calibration. As Postmaster indicates, the issue is whether the glass spins or vibrates. The Letus Ultimate has spinning glass, so it works fine. The Letus Extreme is ground glass and isn't advisable above 1/100th.
 
Cinemek G35 is actually pretty good. Its a static adapter with a ground glass that uses particles too fine for an HD imager to pick up, especially on the HVX200 which isn't even an HD sensor anyway.
 
Thank you all ! very helpful replies, I'll be able to make the right choice now, much appreciated

- I got in touch with a cameraman who shot using Letus at high speed and he said there was graininess but they managed to clean it all up in post
