Large F1.7 aperture to achieve a simple background blur effect. AF/MF and manual focus in real time STM Stepper Motor The nearest focus distance is only approx. 0.30m, the maximum magnification is 0.15x. Optical design with 8 sets of 9 lenses, including two ultra-low ED dispersion lenses › See more product details; Product description YN42.5 mm F1.7M Ⅱ standard fixed focal length lens. Improved second generation lens over the first generation. Drive chip: upgraded, quieter (open and video) Program Optimization: Using a new drive algorithm, for more precise focusing, faster focus speed, effective reduction of focus motor when shooting. Product features: Lens focal length: 42.5mm (35mm equivalent focal length: 50mm) Viewing angle: diagonal 29°, vertical 18°, horizontal 24°. Lens Structure: 8 sets of 9 pieces.
