Particularitiesexact Petri PX5F manufacturer manual, printed pages 25-28: f / 5.6 33mm lens, fixed at 2.8m with a stated sharp range of 1.5m to infinity. Daylight uses 1 / 250s at f / 5.6 (ASA 100) or f / 11 (ASA 400); flash uses 1 / 100s at f / 5.6. This is not continuous program AE. The manual resolves the earlier f / 3.8 versus f / 5.6 conflict. Weight excludes batterys. No optical construction or exact introduction date is established by this undated manual.
