| Ilex Paragon Anastigmat f4.5 lens in Ilex No. 4 Universal shutter |
Ilex Manufacturing Co. was one of America's three main suppliers of lenses for view cameras. It was founded in 1910 by the former Bausch & Lomb shutter designers Rudolph Klein and Theodor Brueck. They invented a delay mechanism that made shutters working independently from climate conditions. Their lens brand was Paragon.
Shutters
Many of the Universal shutters have the speeds T, B, 1/100, 1/50, 1/25, 1/10, 1/5, 1/2, and 1 sec. Most ACME shutters have additional 1/150 sec.
Ilex press shutters
Press shutters are self-cocking leaf shutters. When a "Synchro" variant exists the other variant is unsynchronized.
