So, I have this ancient SA mount Sigma 17-35mm f/2.8-4 EX HSM in the attic camera museum. Haven't used it for years and it has been no use for adapting because of the SA mount and the electronically controlled aperture.
Then I saw this SA - NEX adaptor on Amazon for £12 quid. And I remembered reading somewhere that you can stop down Canon EF lenses by pressing the doF preview button then quickly removing the lens. And I remembered that allegedly Sigma reverse engineered the Canon AF protocols for their own mount.
I stuck the lens on my SD14, set it to F/8, pressed the DoF button and removed the lens... and it stayed stopped down. The adaptor just arrived and I now have a free 17-35mm, er, f/8-11 lens for my A7rii.
I think this is a good thing.....?
Being an EX lens, I'm surprised the aperture doesn't work, when you use that lens on your Sony camera, by mounting it on your MC-11 adaptor.
£12 adaptor - the MC 11 costs about 5x what the lens is worth. My lens not mentioned on the compatability chart
