I'm looking for a good portrait lense to cover 8x10. I'm not into soft focus lenses. I want a really sharp image.

Here I found two images that I like

Here is the description of the photos
Tachihara 8x10
Schneider Symmar-S 360 f/6.8
1/125th sec. @ f/11ish
Kodak EPN (expired 3/05) @ ASA 80
E6 Process

What kind of film+lense combo do you recommend to have really sharp portraits?

Thanks
