From the conclusion...
"The Sony 14mm F1.8 GM (1600 euros) is a new masterpiece from Sony and a new demonstration you can achieve outstanding results in a very small from factors. All the recent GM are a demonstration of this level of excellence (

Image quality is excellent : excellent to outstanding sharpness wide open , corners are also very good to excellent, color rendition and contrast are excellent, distorsion is minimal, coma is minimal. background blur is quite soft for a wide angle lens. AF is fast , silent and efficient, Ergonomics are excellent (small, light, click or click-less aperture ring) and the price stay reasonable for a GM lens compared to the Sony 12-24 F2.8 GM (3300 Euros!)"
