We already listed pros and cons of each model. However, you may also find useful to look at their common strengths and weaknesses shown side-by-side.

Screen

Sigma SD9 has a 1.8" screen with 130k dot resolution and Casio Exilim EX-ZR100 has a 3.0" screen with 461k dot resolution. Both have Fixed screens.

Optical (pentaprism) Viewfinder on Sigma SD9

Sigma SD9 has a built-in Optical (pentaprism) viewfinder. It has a 98% coverage and 0.77x magnification. There is no built-in or optional viewfinder available on Casio Exilim EX-ZR100.

Sigma SD9 features a 3 megapixel APS-C CMOS (Foveon X3) sensor with dimensions of 20.7 x 13.8 mm and a total area of 285.7 mm². Its native ISO range is 100 - 400. Casio Exilim EX-ZR100 features a 12.1 megapixel 1/2.3-inch BSI-CMOS sensor with dimensions of 6.17 x 4.55 mm and a total area of 20.7 mm². Its native ISO range is 100 - 3,200.

Casio Exilim EX-ZR100 has BSI-CMOS sensor, short for Backside Illuminated Complementary Metal-Oxide-Semiconductor sensor. In traditional CMOS sensors, the wiring and circuitry are located on the front side of the sensor, which can block some of the incoming light. BSI technology flips this design by placing the photosensitive elements (pixels) on the backside of the sensor, allowing more light to reach the pixels. This significantly enhances light sensitivity and improves low-light performance. BSI-CMOS sensors are particularly effective in low-light conditions, as they can capture more light, resulting in brighter and less noisy images. This makes them well-suited for indoor and night photography. BSI-CMOS sensors deliver a higher SNR and reduced cross-talk.

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. Casio Exilim EX-ZR100 is equipped with Exilim Engine HS processor and can take pictures up to 4000 x 3000 resolution. It can also take pictures with lower resolution like 4000 x 2656, 4000 x 2240, 2560 x 1920, 640 x 480 with 4:3, 3:2, 16:9 aspect ratios.

No Low-Pass Filter on Sigma SD9

There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on Sigma SD9. 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.

Casio Exilim EX-ZR100 has an image stabilization.

USB Inputs and HDMI Outputs

Both models have USB inputs for data transfer. connector for video signal output.

External Storage Slots
