One top “lowlight cam“ is the small, handy C107XL1.2 / 7-45mm, shutter 225°, fps 1, 9,18, 36, timer from 6 fps to 1 frame/minute , fade, BLC, remote control, flash. Due to this wide shutter angle and the lens you have 20% more light than you get from a fine NIZO 480 - 801 or NIZO professional with varable shutter! I call it “nighteye”.......
A lot of other, very good models are available, which have sometimes only very few differences.
The TOP - silencemodels have features never available with NIZO or other cameras! With manual or auto variable shutter, manual and auto rewind feature, longterm exposure (auto shutter 1/10sec - 1min) auto scene lengths (1-12 sec.), timer, is the A 512 (and 508 or 506) made for professional usage, and the pre models: Bauer Royal series (6E, 8E, 10E).. But do not look only for these fine cams. In good condition they are very rare and expensive!
The first black/silver series with metal housing from BAUER with the cartridge compartment at the right side can check all filmspeeds! Some fine cams were build C1, C2, C3....If you are looking for a camera , very solid, without high sophisticated electronic features but with variable shutter and rewind feature? Here it is: Bauer Royal series (6, 8, 10 ). With single frame 12, 18, 24 (54) fps. The optional BAUER TrickSet gives timer and autofade features. Technic and lenses (from)Schneider) of these Bauer cams are also to find in Rollei and some Porst cams.
