Opticron ES v4 80 overview

  • 1Description

With an updated focusing system to give users the ability to see sharper views faster, the angled-viewing ES v4 80 GA ED/45 Fieldscope from Opticron is defined by its powerful, yet highly portable design. The large objective draws in the light required for use from dawn to dusk, while the compact 15.4" length and its relative light weight of 3.5 pounds allows it to be used just about anywhere.

It features a large objective lens that draws in generous amounts of light to boost brightness during the day and improve its performance in low-light conditions, such as at dawn and dusk. Extra-low dispersion (ED) glass is used and configured in a high-definition tri-element lens system and F-type anti-reflection multi-coatings are applied to the optical surfaces to improve contrast and color accuracy while virtually eliminating off-axis comas and aberrations. This version of the ES v4 is offered here without an eyepiece for users who already have compatible Opticron SDL v2 and HDF T eyepieces.

The ES v4 has its eyepiece holder set at a 45° angle to place the user's head in a more comfortable position whether they are sitting, standing, or lying prone. Its rotating tripod collar also allows the eyepiece orientation, relative to the tripod, to be adjusted for precise placement no matter the viewing position. The body is made of magnesium and aluminum alloys and polycarbonate to help reduce weight while remaining strong and sturdy. The optical tube is O-ring sealed to be waterproof and nitrogen filled to be resistant to internal fogging in extreme conditions. A textured rubber armor offers increased grip security during setup and breakdown, and the focusing knob is split into coarse and fine wheels for easier handling.

Ruggedly designed and built to perform in the harshest conditions, the Opticron ES v4 80 GA ED/45 fieldscope is the ideal companion for bird-watching, hunting, and general observations in the field, at the range, or just about anywhere there are sights to be seen.

Optical Performance
  • Eyepiece required for proper use (fully compatible with SDL v2 and HDF T eyepieces)
  • Large 80mm objective lens diameter gathers generous amounts of light to boost low-light performance
  • Extra-low dispersion (ED) glass corrects for spherical and chromatic aberrations, astigmatism, and off-axis comas to produce crisp and sharp images with accurate colors, especially at the edges
  • Tri-element high-definition objective lens system further improves color, clarity, and contrast
  • Proprietary F-type anti-reflection multi-coated optics improve light transmission for brighter and clearer views with accurate color fidelity
Use and Handling
  • 45° angled eyepiece mount for more comfortable viewing while standing, sitting, or lying down
  • 8:1 dual focusing system enables fast coarse and precision fine focusing
  • Retractable lens hood protects objective against solar glare, which can interfere with clear views, while keeping rain and snow off in inclement weather
  • Rotating tripod collar allows for precise eyepiece placement relative to tripod for the most comfortable viewing
  • Standard 1/4"-20 tripod mount
