正式版对功能进行了改进R-D1是现在市面上唯一采用连动测距(RangeFinder)对焦设计及兼容 Leica M 系列与 L系列及福伦达(需配备转接环)镜头的数码相机。机身改良源于福伦达 Bessa R2,整部机以全手动模式操作,包括手动对焦、手动调校光圈与手动快门上链。除数码影像处理部分。基本上 R-D1整部机都采用全机械设计。R-D1虽然同样使用来自 Sony 的610万像素 CCD(这颗 CCD 也同时应用在 Nikon D70及D100内,所以 R-D1同时拥有1.53倍的焦距放大率),但由于要考虑到连动测距相机镜头与快门距离较近的特点,所以 EPSON 在边缘位置加入增光棱镜。使边位光线吸收得更均匀
The official version of the function has been improved R-D1 is the only available on the market with Rangefinder focus design and compatibility with the Leica M Series and L Series and Foley (need to be equipped with adapter ring) lens digital camera. Body modification comes from the Folenda Bessa R2, the whole machine to operate in full manual mode, including manual focus, manually adjust the aperture and manual shutter on the chain. In addition to digital image processing section. Basically R-D1 whole machine adopts full mechanical design. Although the R-D1 also uses a 6.1-megapixel CCD from Sony (this CCD is also used in the Nikon D70 and D100, the R-D1 has a 1.53x focal length magnification), but due to the consideration of coherent distance measurement Camera lens and the shutter distance is close, so EPSON edge adding glistening prism position. So that the edge of the light absorbed more evenly
