85/100当社のAIによる感情分析
- Q1 2026100/100
Buyers praised this lens for its image quality, solid metal build, useful 40mm equivalent focal length, and compatibility with Olympus OM series cameras. One Italian review called it 'strepitosa' (outstanding).
- Excellent image quality with sharp center even at f/1.4 and beautiful bokeh.
- Solid, all-metal construction feels professional and durable.
- Versatile 20mm (40mm equivalent) focal length ideal for walk-around and general use.
- Fast autofocus and good balance on OM system bodies without stabilization worries due to IBIS.
- Q4 202367/100
Buyers praise the lens for value, weather resistance, and image quality, but note heavy purple fringing when shooting wide open into the sun, resolved by stopping down.
- Value for money and weather resistance make it a versatile four-season lens.
- Purple fringing occurs at f/1.4 with sun in frame, but easily fixed by stopping to f/4.
- Good performance overall for Micro Four Thirds system.
- Chromatic aberration is an Achilles' heel, hard to remove in post-processing.
