Omegon Zoom 20-60x80 (73996) review

A 20–60x80 zoom spotting scope with anti-reflection coating, a retractable dew shield and a photographic tripod thread, sold as an entry-level nature observation instrument.

The bottom line A sensibly featured entry scope described in prose rather than specification — the dew shield is the reason to consider it.

The one feature worth the page

A retractable dew shield. It shades the objective from side lighting, and it keeps the front element from radiating straight to the sky, which is what causes dew. Most spotting scopes at this price have none, and on a damp evening it is the difference between an hour of observing and twenty minutes.

The description, and what it lacks

The maker’s bullets run to prose — imagining a poorly lit forest, promising an image that impresses — and one of them is cut off in the middle of a word. Between them they establish the magnification range, the objective, the coating in the vaguest possible terms, the dew shield and a photographic thread. Nothing else.

Using the zoom well

Find at twenty, then increase. At the top of the range the exit pupil is 1.3 mm and the image is dim; the wide end is where an 80 mm objective earns its size.

The thread without a size

A photographic thread is named. Whether it is the 1/4-20 or the 3/8-16 of ISO 1222 is not stated — and on a scope of this weight that is worth checking before buying a head for it.

Availability

German, French, Italian and Spanish Amazon stores ran from 159 € to 170 € on the day of the survey.

American Amazon catalogue holds a record for it that nobody is selling.

British Amazon store gave no result whatever, so the buy button there opens a search rather than an empty page.

What it publishes, and what it withholds

Strengths

  • A retractable dew shield is genuinely useful and often omitted at this price
  • A photo thread means any tripod will take it
  • A zoom eyepiece removes eyepiece swapping in the field entirely

Compromises

  • The coating is described only as anti-reflection, the weakest possible statement
  • The bullets are truncated marketing prose and one of them breaks off mid-sentence
  • No field of view, weight, close focus or tripod thread size appears

What observers ask about this one

What does the dew shield do at night?

Two things. It shades the objective from side lighting, which raises contrast, and it slows the formation of dew on the front element by keeping it away from the open sky. On an autumn evening that second effect decides how long a session lasts.

What is missing from the coating claim?

A label. “Coated”, “fully coated”, “multi-coated” and “fully multi-coated” each count something specific. “Anti-reflection coating” counts nothing, and cannot be compared with another maker’s claim.
