On my old K1000, the front ring on the lens is focus, back ring is D.O.F / F-stop, Mostly-Single-Function rotary dial on the top for shutter speed
The Panasonic DMC-L1, which is identical to the Leica Digilux 3 except for firmware tweaks, has a shutter speed dial on top and has several lenses with aperture dial. It's only 7.5 MP but those pixels are nice and "fat" - add some sharpening in post-processing and 100% crops are perfectly acceptable. The camera can often be had cheap on eBay in good used condition. As part of the four-thirds family of cameras, it has a crop factor of 2x compared to full-frame 35mm film. If you want a retro feel in an affordable price range (here's glaring at you, Leica M9) this is your camera. The "kit" lens is a sweet Leica-designed 14-50mm/2.8-3.5 with built-in image stabilization. Also available is a 25mm/1.4 which is tack sharp wide open, and a 14-150mm/3.5-5.6 that is the best so-called "superzoom" lens ever made. All of these have aperture rings. Add the Olympus 25mm/2.8 "pancake" lens - no aperture ring (have to use the dial on they body) but slender as a supermodel - and you transform the camera into a great street shooter that will intimidate no one. In my opinion, this is the earliest dSLR that will qualify for "classic" status in years to come. Oh, and it has built-in bounce flash; why don't ALL manufacturers think of that??
