About this item

• A 20mm Z lens for more dynamic astrophotography.
• Multi-focus improves AF accuracy even at close range.
• Point light sources are faithfully reproduced as points, not only at the center but also at the edges of the image.
• The adoption of ED lenses (3 pieces) effectively corrects axial chromatic aberration from close range to infinity.
• The adoption of Nano Crystal Coat effectively reduces ghosts and flares from the sun, which tend to appear in wide-angle landscape photography.
