🔍 Key Features
SmartFocus Concept: The focus wheel is perfectly positioned on the double‑link bridge so you can focus quickly — even with gloves — with only ~1.4 turns from close focus to infinity. Zeiss+2Optics4Birding+2
UHD Optics + Excellent Coatings: Ultra‑High Definition optical system with ZEISS T* multi‑coating and LotuTec® water‑/oil‑repellent coatings. Provides about 90% light transmission, vivid contrast, and reduced glare. Zeiss Sports Optics Shop+1
Reduced Size & Weight: By using 30 mm objective lenses and thinner, closely‑spaced lens elements, ZEISS has trimmed down size vs. larger models. The 8×30 SFL is up to ~20‑23 % lighter and ~21 % shorter compared to the 8×32/40 Victory SF models. Zeiss+2All4Shooters+2
Comfort in the Field: Large exit pupil, generous eye relief, ergonomic eyecups — the design allows relaxed viewing for extended periods. Close focus distance also good for nearby subjects. Zeiss+2Naturbutiken+2
Weather & Ruggedness: Nitrogen‑filled, waterproof/fog‑proof design (400 mbar), rugged construction with lightweight magnesium alloy housing. Resistant to cold and heat extremes. Zeiss+2South West Optics+2
