About this product

Model:  masuyama_2inch_ep_45mm
Part Number:  MOP-45

Legendary Japanese Masuyama eyepieces are back!

The ultra-premium Masuyama eyepieces have near mythical status and are highly regarded and sought after but haven't been available to buy since the 1980's. Now back in production with the same five-element modified Plossl design designed by the well regarded optician Dr Masuyama but updated with modern glass and multi-coatings.

The removable rubber grips makes these ideal for use in bino-viewers.

On the 2 inch versions long eye-relief makes this comfortable to use for eye-glass wearers:

  • 10mm / 85º :  Approximately 6.5mm eye-relief.
  • 16mm / 85º :  Approximately 10mm eye-relief.
  • 26mm / 85º :  Approximately 16mm eye-relief. 
  • 32mm / 85º :  Approximately 20mm eye-relief
  • 45mm / 53º :  Approximately 32mm eye-relief
  • 50mm / 53º :  Approximately 40mm eye-relief
