It's not the camera that will give you the look. It is the choice of film, of processing, printing and a bit of time that gives that look. If you are looking for lens selection then I would definitely recommend either Nikon or Canon. At least in my area in the used film market there are more good lenses available for Nikon or Canon than Minolta or Pentax. Minolta would probably be my third choice as there seems to be more good Minolta glass then Pentax. They generally will have more accessories available as well such as winders, motor drives etc. You may have to pay a few dollars more for say an F2 or AE-1 but they were top of the line cameras in their day with the finest of builds. What ever you choose make sure to check out the meter and make sure it works as well as the shutter. A good used camera shop will have gone over all of that and will either have fixed any problems or let you know what problems it has.
