理光映像发布支持35mm全画幅影像传感器的标准变焦可交换镜头HD PENTAX-D FA 24—70mmF2.8ED SDM WR。该款镜头安装在全画幅可交换镜头数码相机时,可覆盖从超广角到标准的焦距,实现了焦距24~70 mm,全程恒定最大光圈2.8的大口径标准变焦镜头。镜头在12组17枚的镜头结构中,采用了3枚超低色散(ED)玻璃镜片、1枚异常低色散玻璃镜片以及3枚非球面镜片的设计,在确保充足的周边光量的同时,各种像差也得到了有效的补偿,从而实现了清晰、高分辨率的细致影像拍摄。另外,采用了新型超声波马
Ricoh Image Releases Standard Zoomable Interchangeable Lens with 35mm Full Frame Image Sensor HD PENTAX-D FA 24-70mmF2.8ED SDM WR. The lens mounted on a full-frame interchangeable-lens digital camera covers a wide-angle standard zoom lens from ultra-wide-angle to standard focal lengths, achieving a focal length of 24-70 mm and a constant maximum aperture of 2.8 throughout. Lens In the 12-lens, 17-lens configuration, three ultra-low dispersion (ED) glass lenses, one unusual low-dispersion glass lens, and three aspherical lenses were used. In addition to ensuring adequate peripheral light intensity, Aberration has also been effectively compensated for clear, high-resolution, detailed image capture. In addition, the use of a new type of ultrasonic horse
