[Prototype] Cat 61 WIFD

This Cat 61 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, this prototype resulted in a few differences from the final production configuration: Soft carry case not included Mounting plate shows significant cosmetic scratches from development and testing. These marks do not affect normal mounting or operation. Prototype extendable dew shield — unlike the final production Cat 61 WIFD, this unit was built as part of an early trial for a telescoping dew shield design. The dew shield is longer than the production version and can be extended further, giving this prototype a distinctive feature not found on the standard model. Includes a one-year warranty with an official William Optics warranty card. Optical performance is identical to the standard production Cat 61 WIFD. The prototype designation refers to the mechanical configuration and cosmetic condition described above, with no compromise in optical quality or imaging performance.
