Dog Schidt Optiks 'TRUMP28' (Attachment)
Wide Angle Attachment
TRUMP28 Optical Attachment fits to the TRUMP58 lens to provide a 28mm effective focal length without degrading optical performance or character allowing for a matched optical signature through all focal lengths.
As with all of our lenses, the TRUMP28 attachment has been designed for use on large sensors up to and beyond 43mm diagonal (full frame) and maintains a true f2.0 aperture with minimal (<1/3rd T-stop) transmission loss.
External diameter matches the 38mm, 58mm and 88mm portions with 86mmx0.75 filter thread and a 95mm external diameter.
