About
A four-element telecompressor corrector built to cover large-format cameras with 9-micron pixels such as the STL11000 and 16803 chips. Originally developed with the 130GTX, it stayed recommended for the longer-focal-length TEC 140, 160 and 180 f/7 refractors, each of which needs the S35RFAA adapter and its own back-focus spacer.
