The B-4 was the less expensive manual focus companion to the autofocus B-3. The
column was extruded aluminum similar to the B-3, but the B-4 had a "lift
and lock" elevation system as compared to the B-3's rack and pinion
system. And while the B-3 had an adjustable triple condenser system, the
B-4 came with double condensers requiring supplementary condensers for printing
6x6 and 35mm formats. The supplementary condenser lens for 50mm or 75mm lenses
was purchased together with the corresponding lensmount.
Rather than the familiar system using brass focus rods, focusing on the B-4 used a knob operated cam system. The lamp used in the B-4 was the small PH111, allowing the lamphouse to be made smaller compared to that on the Super B Used Advice: Still useable if complete and in good condition, but not as convenient to use as later models. All parts and accessories have been discontinued for decades. |
