A new apochromatic refractor with high-performance Super ED glass. Due to its special refractive properties in the lens system, the FPL53 glass can enable an extremely good correction of residual chromatic errors.
The advantage of these SD refractors lies in their short overall length and the associated low weight. The SD glass is designed to bring all rays from violet through red, blue, yellow and green together very precisely onto the same plane. The special lens material reduces chromatic aberration across all color components. In combination with the new, optional SD Reducer HD Kit or SD Flattener HD, these refractors enable illumination in a 44mm image circle, sufficient for full-frame sensors.
