Promaster 2X Digital Auto Focus Teleconverter for Canon EOS
Today's digital SLR's have more precise requirements than traditional film cameras. The anti-aliasing filter and silicon based CCD and CMOS sensors in digital SLRs are HIGHLY reflective. PROMASTER's 2x Digital Auto Focus Teleconverter uses anti-reflection coatings that are specifically formulated to pass light reflected from the anti-aliasing filter and silicon based CCD or CMOS sensor of digital SLRs resulting in better pictures. In addition, these converters have been specially tuned to accomodate the more precise specifications required in order to insure communications compatibility between the digital camera and lens.
