Hi George,
The Nikon 35ti and 28ti sound like the smallest cameras that offer what you are after (they don't have a full Manual mode, but they do have aperture priority and exposure compensation), they are "pocket sized" and reasonably rugged - not to mention the allure of Titanium and that glorious "analogue display" on top. I wouldn't say it is "tack sharp" wide open at f2.8, then again I don't think ANY lenses (maybe just a few exceptions) are "tack sharp") wide open. At f2.8 this lens is pretty darn sharp, but it is best at f5.6. I have a 35ti and am impressed. I also have a Konica Hexar AF, which is the other camera which may meet your criteria. It has an f2.0 lens (a very good lens too - like the Nikon), a full Manual mode and a "silent-mode", however it is a larger compact than the 35ti (not quite pocket sized, so I end up using my Nikon more) and it's maximum shutter speed is 1/250th versus the Nikon's 1/500th (both are Leaf Shutters). The Konica CAN take filters (unlike the Nikon), so you could use a ND filter in bright sunlight, and depending on what you want to use the camera for, having access to filters could be a huge deal !!
