Regarding poor sharpness, lots of factors come to play:

Rule of thumb is that shutter speed and focal length should be closely matched: 28mm shot at 1/30, 50mm shot at 1/60, 85 at 1/100, etc. Of course scene lighting, aperture and film ISO will all dictate these.
Good technique and the use of tripods or image stabilized lenses (not available on the F3) can greatly contribute to sharper results particularly if the object of interest is static.
