If you don't mind me skipping over the middle pages of this thread:
"used to own a manual focus lens for film cameras that was a 35 to 150 mm"
I don't know what lens you're talking about there, but I have a 28-105 2.8-4 Sigma that comes from AF film days, which is very nice if stopped down somewhat. They are somewhat quirky in the bright, but really pretty nice and cover about that range of FOV.
The price is quite reasonable, (I think I paid a bill at Keh) being the niceness of them. If one turns up. I'm using one for a placeholder for a Tammy 28-75, and having fun with the extra bit of reach in the meanwhile. If you want to use on digital, ...put a good sized hood on there and try to stay under 100mm.
