I think your proposed set up would be pretty ideal for interiors and architecture and I think it would be my choice too. Out of interest what camera are you looking to move to Sigma from?

My computer is a 2011 Mac Mini Server with 16Gb RAM and I too experience some issues with High Sierra either within the OS (like sleep) or affecting other software but SPP6.6 is not one of them. ...

I have had several Merrill cameras - now only the SD1M.  I have recently bought a DP1Q. Yes, this seems a non-issue now.  There can be a certain softness in the under exposed parts of the image ...

Yes, and presume the same for the 16mm DN lens too?

Yes, I also wish for a wide angle prime for the SD1M and had hoped that the 14mm on the DP0Q might be released as a prime lens or indeed the more recent 16mm for mirrorless mount cameras. Waiting!

Managed a score of 8.

Yes, and a wide-angle prime perhaps the 14mm from the DP0Q or the 16mm from the DN line would be good options too.

Yes I tried it and thought it was OK.  However I'd much prefer that Sigma's next flagship camera has an OVF with a Live View rear screen.

Yes, I have a basic SA to m43 adapter which allows me to mount a lens and use it wide  open. This works for me as mostly my video is interviews and using F2.8 or F1.8 lenses on m43 is about ideal ...

Interesting thanks.  Do you also have experience of the previous 85mm DG lens and if so how does it compare?

PM sent.

Yes, this is a more useful lens for me than the 12-24 F4.  Looking forward to it.

Yes, I too have liked the idea of the RICOH GXR concept in a Sigma Foveon package.

I also (as speculation) think this is coming.  As someone who came to photography after having worked for many years with video cameras (using 3CCD sensor cameras prior to Bayer cameras) this ...

Interesting Tilt Shift adapter too

Forgot to add a link to the For Sale forum.

Final bump before offering for sale elsewhere......

So, I added an extra thumb up to Don's post...:-)

I don't know of any adapters but there are mount conversion options - http://leitax.com/leica-lens-for-sigma-cameras.html
