The frosted glass metal structure is resistant to dust and steam, and the 6 multi-coated elements in 5 groups prevent flare. ・It features a comfortable user experience and a nostalgic industrial design thanks to its metal construction. It consists of a highly polished metal mount body and a knurled metal focus ring. ・It provides depth of field, and the distance is marked in both feet and meters. The front element does not rotate, making it very easy to use polarizing and gradient filters. Pressing the plastic lens cap may cause it to come off during use. ・The Meike 35mm f/1.7 lens is a good quality and attractive optical lens with beautiful colors, nice bokeh, and controlled chromatic aberration. ・Recommended for manual purists who will be rewarded with excellent central sharpness in your portraits and other types of photography.
