Description
A new apochromatic refractor with high-performance Super-ED glass (= SD). The FPL53 glass reproduces an extremely clear and sharp image by an exceptionally high degree of elimination of residual chromatic aberrations. The advantage of these SD refractors is their short length and low weight.
The SD glass is designed to bring all beams of violet, red, blue, yellow and green very precisely together on the same plane. The special lens material reduces chromatic aberration across all colors. In combination with the new optional SD Reducer HD Kit or SD Flattener HD, these refractors allow illumination with a 44mm image circle for full format SLR cameras.
