I currently use a 180mm Nikkor-W as my 'normal' lens. At wide open, it doesn't look very sharp on the ground glass, but stopping it down to f/22 produces acceptable results. My wide-angle lenses however, are much sharper on the ground glass and once they're stopped down, they produce incredibly sharp images (at the center at least).
Now I'm considering a 210 or 240mm lens so I can get a little more magnification. Which are the sharpest lenses in this range? I'm a little disappointed with the 180mm Nikkor, but maybe my expectations are too high. Should I look into Schneider/Rodenstock/Caltar/Fuji lenses instead, or is this slight unsharpness normal with longer lenses? What's everyone's advice/opinion?
