Subsequently, three modifications of the original R-D1 were produced - R-D1s, R-D1x, and R-D1xG. R-D1R-D1 was jointly developed by Seiko Epson and Cosina and manufactured by the latter, which also builds the current Voigtländer cameras. It uses Leica M-mount lenses or earlier Leica screw mount lenses with an adapter. An unusual feature to note on the R-D1 is that it is a digital camera that has a manually wound shutter with a rapid wind lever. The controls operate in the same way as film-based rangefinder cameras. Data such as white balance, shutter speed, picture quality, and shots remaining are all displayed with servo driven indicators on a dial like a watch face (made by Epson's parent company Seiko). With the rear screen folded away, it is not obviously a digital camera. R-D1 and all of the subsequent modifications of the camera have been using the same 1.5x crop factor sensor, interline-transfer CCD (Sony ICX413AQ). The same sensor as used in Pentax *ist D, Nikon D100. Sensor originally dates to 2002. R-D1sThe successor of R-D1, the R-D1s was released in March 2006. The Epson R-D1s is mechanically identical to the R-D1, but with a firmware upgrade. It adds:
Users of R-D1 could upgrade their camera to have the same functions. {{anchor|R-D1xG}}R-D1xThe successors of the R-D1s, the R-D1x and R-D1xG[2][3] were made available from 9 April 2009 in Japan only. They feature very similar feature set except for few modifications:
On 17 March 2014, Epson announced that the R-D1x is discontinued.
