@Jim. The lens is a triplet, the Novar 75mm f4.5. I too was very surprised at its resolving power, even at f5.6. Not to mention the pleasant, not too strong, contrast it delivered.
@Paul. Nicely done. I really like the first two. Acros is not for all, but its one of my three favourite films. Even in daylight, but at night it rules supreme.
