Key Features Compact Size & Light Weight The AF 75mm F1.8 X is the smallest (69.3mm/2.7in length) and lightest (257g/26.5oz weight) autofocus telephoto lens designed for Fuji X-mount users. Its compact size and lightweight maximize the portability and usability and it's a great match to compact Fujifilm mirrorless cameras. Excellent Resolution in All Areas of the Image The 2 HR (High Refractive) and 3 ED (Extra-Low Dispersion) glass elements of this new AF 75mm F1.8 X provide a stunning contrast and resolution in all areas of the image. Samyang's advanced coating technology maintains excellent image sharpness and clear image even in poor lighting conditions. Impressive Background with Refined and Beautiful Bokeh The F1.8 maximum aperture of this new AF 75mm F1.8 X lens provides an extremely narrow depth of field expression and amazing out-of-focus images. A 9-blade circular aperture design creates a beautifully blurred background at a narrow depth of field. Its smooth bokeh and blurred background can make subjects stand out in images with deep dimensional impact.
