  • Excerpt: I'd hoped this lens, which seems to have a similar optical layout to the greatly respected P67 55-100 lens, would be as sharp. Wide open, the lens is very soft in the outer 1/3 of the frame. Not until stopped down to f8 is most of the frame sharp and contrasty. By f11, the whole frame is sharp. This is decidedly not the same quality as the P67 55-100. The 55-110 zoom also uses an 82mm filter, larger than most other P645 lenses.
  • Pros: small and convenient
  • Cons: not sharp until f8-f11; req large 82mm filters
