TS-Optics Flatfield Eyepiece FF 27 mm with 53° apparent field of view Reviews
3/3 Reviews
Wrote by Gottfried M. on 28.12.2021
"Wir benutzen das 27mm Flatfield Okular am Bino (TS 82mm 90°) um schwache Vergrößerungen zu ermöglichen. Der Einblick ist unproblematisch, ganz wichtig beim Bino, die Randschärfe ist gut. Es war die richtige Wahl für unseren Zweck, würde es wieder kaufen. "

"gut orthoskopisch, maßstabsgetreu gute Randschärfe"

"Gutes Okular, wie bei allen Produkten gibt es noch was Besseres"
