The current issue of Pop Photo (Aug '98) happens to have a test of the
"normal" lens for the new AF Pentax 645. The results published in
lines per mm.
Resolution
F/ Center Corner
2.8 55 (Exc) 42 (Exc)
4 50 (Exc) 41 (Exc)
5.6 45 (VG) 41 (VG)
8 63 (Exc) 44 (Exc)
11 70 (Exc) 50 (Exc)
16 63 (Exc) 45 (Exc)

They describe this lens as: "A superb normal lens"...hope this
