In this detailed comparison, I’ll explore how these two models perform across major photography genres including portrait, landscape, wildlife, sports, and more. Along the way, I’ll share insights gleaned from hands-on usage, dissect technical specifications, and ultimately help clarify which camera suits your photographic pursuits and budget. Let’s begin by sizing them up in the real world.

First Impressions and Handling: A Tale of Ergonomics and Design

Physically, these cameras couldn’t be more different, yet both carry a rangefinder-inspired mirrorless style. The Canon M100 measures a compact 108×67×35 mm and weighs just 302g - an ultra-light companion perfect for everyday carry and travel. The Sigma Quattro H, by contrast, is a considerably larger beast at 147×95×91 mm, reflecting its APS-H sensor and more robust build.

Picking them up side-by-side reveals the Canon’s supreme portability and intuitive handling focused on ease-of-use. Its minimal, approachable layout and tilting touchscreen usher beginners straight into photography with fewer distractions. On the other hand, the Sigma Quattro H’s bigger grip and heavier frame give a confident feel for prolonged shoots but may intimidate those after simplicity.

Looking at the top controls, the Canon employs a streamlined approach with basic dials and buttons to keep operation straightforward.

The Sigma offers a more segmented control scheme catering to advanced users who appreciate direct access to exposure parameters and bracketing. It’s reminiscent of classic DSLRs with clear separation of functions, although the lack of a touchscreen means menu navigation relies heavily on physical buttons.

Both cameras fall short on weather sealing - only the Sigma boasts environmental sealing, which might sway landscape shooters who venture into harsher climates.

Sensor Technology: Conventional CMOS Meets Revolutionary Foveon

At the heart of any camera is its sensor, arguably the most influential component on image quality. Canon’s M100 sports a standard APS-C CMOS sensor measuring 22.3×14.9 mm with a resolution of 24 MP. This sensor uses traditional Bayer filter technology paired with Canon’s DIGIC 7 processor, offering good dynamic range, respectable color depth, and solid low-light performance.

Sigma’s entry, however, employs a unique 26.6×17.9 mm APS-H Foveon X3 sensor, packing 45 MP resolution by capturing full color information at every pixel location via stacked photodiodes. This design bypasses the Bayer matrix, promising exceptional color fidelity and sharpness - especially when printing large or doing fine art photography.

But the Foveon sensor isn’t without quirks. It tends to lag behind traditional sensors in high ISO sensitivity and continuous shooting speed, reflecting a deliberate trade-off favoring image quality over versatility.

In practical tests, the Canon’s sensor shines under varied lighting - ISO 1600 images maintain clean noise levels, and JPEGs have natural skin tones crucial to portrait photographers. The Sigma demands base ISO shooting and steady support but rewards with extraordinary color nuances and fine detail retention thanks to its layered sensor structure.

Autofocus Systems: Balancing Speed with Precision

Canon designed the M100 for everyday use, equipping it with 49 autofocus points utilizing hybrid phase and contrast detection. Face detect and eye detection AF bring added convenience when photographing people and pets.

Sigma sticks with 9 focus points relying on contrast detection AF, which is painfully slow compared to Canon’s system. It’s best reserved for deliberate compositions rather than action or fast-moving subjects.

In wildlife and sports scenarios, the M100’s 6.1 fps continuous shooting rate and agile AF tracking hold a clear advantage - experimenting in the field confirmed it locks onto birds in flight and kids on the playground with minimal hunt.

Meanwhile, Sigma’s sub-4 fps speed and slower focusing mean it’s more comfortable on static subjects or landscapes where precision matters far more than speed.

Screens and Viewfinders: How You Frame and Review Your Shots

Canon’s 3” 1,040k-dot tilting touchscreen is a strong feature for vloggers, street shooters, and casual photographers who prefer framing at odd angles and tapping to focus. The touchscreen feels responsive and makes menu navigation quick and approachable.

The Sigma offers a higher resolution fixed 3” rear screen at 1,620k dots, though it lacks touch capability. Its electronic viewfinder, sporting 2,360k dots and 100% coverage, fills a niche for those who want an optical-like framing experience with ultra-sharp preview fidelity.

If you love eye-level shooting or well-composed landscapes, the Sigma’s EVF enhances accuracy and immersion. Casual users, however, will appreciate Canon’s flexibility and touchscreen ergonomics.

Image Samples: Putting Theory into Practice
