Before WWII Zeiss made 4 different 165mm Tessar lensesof varying maximum apertures - f2.7, f3.5, f4.5 and f6.3, all covered 5x4 but the slower lenses had far better definition. Meyer,Ross, Dallmeyer and other European companies made 165mm (or 168mm) lenses/
Ilex made a 165mm f6.3 Acutar which was coated.
