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.....?

David,

Indeed it is, making good use of an old lens.

What's the image quality like on the Sony A7Rii.?

Kinda like any other camera!  I can't say it seems any different from any 12MP+ camera I've used. I prefer my m4/3 gear for its tiny, lightweight lenses. Especially when slogging around in the boiling sun.

In saying that, the one thing I haven't been able to do is the thing I got it for, larger prints.  I've been trying to get hold of an Epson P900 A2 printer but they don't seem to exist in the UK for the last couple of months.  My belief is that the sensor will shine with larger prints, but it remain an untested belief until I can get hold of a printer.

Here's an example shot from yesterday. Dovercourt Far lighthouse (Harwich, Essex).

It's quite good for long exposures because you can (usually) get away without Long Exposure Noise Reduction.  Halves the taking time which is a good thing with 6 minute exposures.

I notice the camera is operationally quite slow. Reminds me of my Sigmas
