You don't say if it is AF or manual focussing. I would think with modern cameras, well as modern as you are likely to get for film use, the Nikon F80 would do if you are using auto-focusing. That is lightweight, compact and relatively small when compared against the F100/F90/F801/F601 and that the reason I use them when I am out on my motorcycle.

For manual focus, perhaps a FE2/FM2or an FA or but I cannot say if they will meter at the levels you are asking for.
