PENTAX SMC XW 7mm Eyepiece 1.25" camera case

SKU CH-M57H-HX10G

A 7 mm eyepiece with 70° field of view and 20 mm eye relief for 1.25" focusers on PF-65, PF-80 and PF-100 spotting scopes

  • High magnification detail with 7mm focal length
  • Crisp bright views via eight-element low-dispersion glass
  • Comfortable extended viewing with 20mm eye relief
  • Wide immersive perspective from 70 degree field
  • Versatile 1.25 inch fit for many scopes

Optics for PF-65 to PF-100 Scopes

The Pentax SMC XW 7mm Eyepiece fits PF-65, PF-65 ED II, PF-80 and PF-100 series spotting scopes plus any telescope that accepts 1.25" eyepieces. It produces high magnification for detailed astronomical or terrestrial observation. Eight elements in six groups use low-dispersion lanthanum glass with antireflection multicoatings.

Weatherproof Build and Comfort

A weatherproof body protects the optics during outdoor sessions. The generous 70 Degree apparent field of view and long 20mm eye relief provide comfortable viewing for extended periods. Crisp, bright images with high resolution and minimal distortion result from the optical design.

Upgrade from Narrower Eyepieces

Observers moving from narrower-field or shorter-relief eyepieces gain a more immersive view and easier eye placement. The jump is worth it when you need maximum detail at high power without eye strain. Buyers who require lower magnification or wider true fields should consider other focal lengths.
