PENTAX XF eyepieces offer high-refraction, low-dispersion lanthanum glass elements to provide high-resolution images with minimal aberrations. PENTAX-original smc full-surface multi-layer coated optics reduce glare while providing maximum light transmission and color quality. Advanced computer simulation design technology was developed to reduce internal reflections, producing brighter, clearer images. Ideal for observation and photography of planets.
With JIS Class 4 weatherproof construction, the XF eyepieces are more durable and water resistant.
