[Prototype] Cat 71 WIFD

This Cat 71 WIFD Prototype comes directly from our product development process and retains the same optical design and imaging performance as the standard production model. During development, a few mechanical details in this prototype version resulted in differences from the final production configuration: Soft carry case not included Front cap without an integrated Bahtinov mask — due to a development-stage mechanical limitation, the Bahtinov mask could not be installed in this version of the front cap. For users relying on electronic autofocus, this does not affect normal focusing operation. Includes a one-year warranty with an official William Optics warranty card. Optical performance is identical to the standard production Cat 71 WIFD. The prototype designation refers only to the differences noted above, allowing us to offer this unit at a reduced price without compromising optical quality or imaging performance.
