"The ACB-CA can also be used to set the aperture of those lenses that have only motorised aperture. The internal battery is rechargeable. The used focal length and the current aperture are displayed on a OLED screen on the lensplate."

The aperture of the Canon 24mm tilt shift lens mk2 can or cannot be controlled electronically with the ACB-CA adapter?

Thanks.

I have been using the auto Cambo Lens plate (ACB-CA) with my Canon TS-E 17 and 24. The lens plate itself it works beautifully but there are restrictions, using it with the Sony A7r Mk2.
When shifting on the grip sides, you only get 4 mm of shift before running into the Grip. Not a problem with the original A7r.
This should not be a problem with the Nikkon mount lens panel as there is a extra 2.5 mm of flange back.

Also and, When using both TS-E lenses you have to have them focused on infinity and Not past infinity. You lose sharpness especially in the corners.

All this makes the Actar seemed very attractive.
I have used the Samyang on a sony a99 and it was very good but there were reasons why I sold it and got the canon TS-E lenses instead. Barrel distortion and flare.
