Adapter to control aperture on EF lens

I am buying an instant camera that takes EF lenses just does non have whatever electronic connectors to the lens. This means I can’t control aperture on my erstwhile lenses.
Does anyone know of an adaptor ring that gives ef lenses manual aperture settings?

The aperture is set electronically, and so the merely way of using the lens’ iris without electronic contacts is to set the aperture on a Catechism DSLR, press the terminate downwards push and remove the lens without switching the camera off or releasing the stop downward push button.  Put it back on the DSLR to change the aperture and repeat.

Some mirrorless camera EF lens adapters accept their own mechanical diaphragm which lets you brand a approximate at the aperture you’re setting.  There are likewise some expensive adapters (mainly Fringer, Metabones and Sigma) for some mirrorless cameras.

The aperture is set electronically, and so the just way of using the lens’ iris without electronic contacts is to set the discontinuity on a Canon DSLR, printing the stop downward button and remove the lens without switching the photographic camera off or releasing the stop down button. Put it dorsum on the DSLR to change the aperture and repeat.

Some mirrorless photographic camera EF lens adapters have their own mechanical diaphragm which lets you lot make a guess at the aperture you’re setting. At that place are likewise some expensive adapters (mainly Fringer, Metabones and Sigma) for some mirrorless cameras.

Probably easier to drill holes in lens caps for various f-stops, and swap lens caps to go the right exposure. Ideally you use a drill press with an x-y bed and so you lot can drill out the exact center. You lot’ll then need to de-burr the hole.

Yous might exist able to buy pre-made sets.

Pro Tip: Don’t Try an STM Lens

If you call up the electronic discontinuity is a problem, you lot’ll actually hate the electronic focus of the STM lens. No mechanical focus at all.
