<p>Does anyone know what camera the 6" (or 150mm) Xenotar lens usually was put on? <br /><br />It would be helpful to know if other lenses are available in the same barrel mount for that camera. They could just as readily be adapted to a Compur 3 or a Copal 2 shutter as the Barrel-Mounted-Xenotars. <br /><br />All these high speed aerial lenses should be exceptionally high quality, but the Xenotars are outrageously priced for a lens that usually needs to be retrofitted (with the exception of the ones in Compur shutters made for Technika 4x5 cameras). </p>
