Designed for: 175 mm f/8 StarFire EDF
Application: Digital imaging with CCD and DSLR cameras. Also suitable for video and 35mm film cameras.
The photos on this page depict the 160 Field Flattener since we did not have a photo of the 175 version at the time this webpage was written. Please note that the mechanical parts are the same except the length of the extension and the engraving on the retaining ring. The optics, however, were designed specifically for the 175 StarFire.
The 175 f/8.3 Prime Focus Field Flattener is made specifically for the 175 f/8 StarFire EDF with its 4" focuser. The effective speed of the 175EDF will be f/8.3 with this accessory.
