Pentax FB 頁面的情報: smc PENTAX DA 18-270mm F3.5-6.3 ED SDM - Optical Design The new smc PENTAX DA 18-270mm F3.5-6.3 ED SDM has several features to help optimize overall image quality. The incorporation of two extra-low dispersion (ED) elements into the design helps the lens deliver bright, high-resolution images even at the edges, while effectively minimizing chromatic aberration. Rounded lens diaphragm blades render out-of-focus areas in the image with an exceptional smoothness, resulting in a beautiful lens bokeh* and minimizing the streaking effect of point light sources. *bokeh – a lens characteristic referring to how a lens renders out-of-focus points of light 圖:http://tinyurl.com/96ppdxb SDM對焦、ED低色散設計、旅遊鏡的焦段 會燒到P家人嗎? -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 70.184.223.240
