      Photography Features

      Sigma SD1 Merrill is equipped with Dual TRUE II processor and can take pictures up to 4800 x 3200 resolution. Epson R-D1x can take pictures up to 3008 x 2000 resolution. It can also take pictures with lower resolution like 2240 x 1488 with 3:2 aspect ratios.


      Lens Mount

      Sigma SD1 Merrill has Sigma SA lens mount and Epson R-D1x has Leica M lens mount. Due to their APS-C sensor their crop factor (also called lens multiplier) is equal to 1.5x. This means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 1.5.


      No Low-Pass Filter on Sigma SD1 Merrill

      There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on Sigma SD1 Merrill. This results in a slightly sharper image but may also introduce moiré patterns and aliasing artifacts when photographing subjects with fine, repetitive patterns or details.


      No Image Stabilization

      The cameras do not have image stabilization. On Sigma SD1 Merrill it means that you need lenses with optical image stabilization for vibration reduction. As for Epson R-D1x nothing can be done.
