The original R-D1, announced by Epson in March 2004 and discontinued in 2007, was the first digital rangefinder camera. It also was the first consumer digital mirrorless interchangeable-lens camera (MILC) camera. Subsequently, three modifications of the original R-D1 were produced - R-D1s, R-D1x, and R-D1xG.
R-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 mechanical shutter, despite not being a DSLR. 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.
The 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:
- JPEG+RAW mode
- Quick view function
- Adobe RGB mode
- Noise reduction for long exposures
Users of R-D1 could upgrade their camera to have the same functions.
- Larger 2.5" LCD display (vs 2" in the previous model) but with the same resolution - 235K
- LCD is no longer articulated and cannot be closed
- Support of SDHC memory cards which increased max. capacity to 32 GB (vs. 2 GB for previous models)
- Improvements in accessibility of rangefinder adjustment
- R-D1xG model also includes removable grip
On 17 March 2014, Epson announced that the R-D1x is discontinued.
