I've got an old Gowland aerial 4x5 camera that came with 150mm Schneider Symmar-S. I'm possibly looking to replace this lens with a more modern lens that has better coatings and that is sharper using a small f-stop number (e.g. f/8). Because I use ASA 100 B&W film with a medium yellow filter I find that I'm usually stuck at 1/250 sec at F/8. Ignoring the fact that I could go to a an ASA 400 film to get 2 more stops, does anybody have any recommendations for lenses with excellent sharpness and contrast at f/8?? My research on the net seems to indicate the Rodenstock Sironar-S 150mm might be the best. But that is a pricey piece of glass and I surely don't need that much coverage! I'm thinking that a lens like the Rodenstock (apo??) Sironar-N or a Fuji-W might be good. I'd love a lens that is at it's sharpest at f/5.6, but that doesn't seem likely.
