Canon to ZWO Adapter with electronic aperture settings

paulchen

Hi,

modern Canon lenses (and comptible products) have no longer any manual aperture control. The aperture is controlled via some electronic contacts and a motor. When switching off the DSLR, the aperture is driven to full open by the camera, so it is useless with an ASI cooled camera, because you have no possibility to set any aperture with it.

It would be great, if there is a ZWO Canon adapter available with built in electronic contacts, so you can connect it via USB (for example) to the ASIair and control aperture of the lense. This adapter should not modify the backfocus.

Here is an example of such lense control adapters:

Hello,
Do you have any news of an integration of the Astromechanics product, or of the development of a zwo product which would allow to control the aperture and focusing of canon lenses?
Thank you
Guillaume.
