Sigma SD9 can take pictures up to 2268 x 1512 resolution. It can also take pictures with lower resolution like 1134 x 756, 756 x 504 with 3:2 aspect ratios. Sigma SD10 can take pictures up to 2268 x 1512 resolution. It can also take pictures with lower resolution like 1134 x 756, 756 x 504 with 3:2 aspect ratios.

Lens Mount

Cameras have Sigma SA lens mount. Due to their APS-C sensor their crop factor (also called lens multiplier) is equal to 1.7x. This means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 1.7.

No Low-Pass Filter

There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on either of the cameras. 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 SD9 it means that you need lenses with optical image stabilization for vibration reduction. As for Sigma SD10 nothing can be done. On Sigma SD10 it means that you need lenses with optical image stabilization for vibration reduction. As for Sigma SD9 nothing can be done.

USB Inputs

Both models have USB 1.0 (1.5 Mbit/sec) inputs for data transfer.

External Storage Slots

Cameras have a single CompactFlash (Type I/II, UDMA compatible) card slot.

Shutter

Shutter speed can go up to 1/6000 sec on Sigma SD9, and up to 1/6000 sec on Sigma SD10.

Flash

Cameras have no built-in flash but an external flash may be connected to both of them. The fastest flash synchronization speed is 1/180 sec on both cameras.

Sigma SD9 and Sigma SD10 bodies have the same dimensions of 152 x 120 x 79 mm (5.98 x 4.72 x 3.11") and they both weigh 950 g (2.09 lb / 33.51 oz).
