Last chance for these old lenses

I have way too much camera equipment, and most of it I don’t even use, so I’ve been on a selling spree lately. I sold a few things including some lenses, but when I found these two sitting on a shelf in the closet, they made me pause. They are the Zeiss 16-70mm f/4 and the Sony G 70-350mm. I made so many good images with these two back in the day… but I haven’t touched them in a while. So, to decide whether I love them or list them, I’m taking both out to Lake Michigan to shoot some amazing winter scenes and see if they can still perform.
