Camera suggestions

Thanks everyone for your kind replies. I have many older Sigma SA mount lenses going back to the days of my SD10/14/15. In general I seemed to switch to the DP then DPMerrill cameras as soon as they came out mainly for the growing # of pixels and resolution so important for landscapes. I'm a rock and tree counter LOL.

Analyzing what I miss most in the DPx cameras, it's an integral viewfinder! I hate composing from and on a screen. I've tried external viewfinders, sunlight blocking gadgets, used the vertical lines on the screen along the horizon etc without much success. Nothing beats holding a camera to the face.

I still process exclusively in SPP, shooting RAW+ JPEG to use the Jpegs for quick screening, then process selected RAWs. I've tried other cameras but usually then gave them away to family (including the heavy, large FF Canon). I just can't carry a huge cam and multiple lenses around these days. I tried a SD1 in Death Valley on one of our post PMA Sigma outings and found it heavy with big lenses. I don't think I'll go SD1. How much lighter or smaller is the SDQ or is it still a beast?  I only enjoy processing in SPP. I'm still somewhat unclear about lenses for the SDQ. I want the option of at least one mid-zoom. That's the strike against the prime DPQs for me.

I'm still somewhat unclear on what lenses work on the SDQ. All SA mount? Correct? But then it's just a question of what auto focuses and is sharp?

Thanks, Sandy
