This new APO guarantees a chromatic correction at the highest levels thanks to a precise and maniacal construction and numerous checks, both in the production and in the sales phase; the image is not affected by any chromatic aberration and remains very clear and well contrasted.

EXTRA-LOW DISPERSION APOCHROMATIC
This apochromatic refractor manages to achieve very high levels of chromatic correction thanks to the combination of two optical glasses, the first is an Ohara (Japan) FCD1-B element while the second is a Lanthanum element, this combination produces a product free of chromatic error , managing to achieve much better performing results than a corresponding doublet refractor.

DOUBLE FOCUS
It is possible to reduce the focal length of the 80 APO ED with its dedicated 0.8x reducer that you find among the recommended products, this allows you to reduce the focal length to 450mm and have a ratio equal to F/5.6
