Sensor and Image Quality: The Core of Any Camera

At the heart of any mirrorless camera lies its image sensor. Both cameras use APS-C sized sensors - a preferred size for balancing image quality and lens portability - for crop factors of 1.6x (Canon) and 1.5x (Sony).

Canon EOS M100 uses a 24.2MP CMOS sensor paired with DIGIC 7 processor, delivering detailed 6000 x 4000 pixel images. Alongside decent color depth (23.5 bits) and excellent dynamic range (13 EV stops at base ISO), it produces vibrant, lifelike images. The aperture anti-aliasing filter helps reduce moiré but can slightly soften fine detail, noticeable at 100% pixel peeping but well-balanced overall.

Sony NEX-5N features a 16.1MP Exmor CMOS sensor combined with the original BIONZ processor. Despite a lower resolution (4912 x 3264 pixels), it benefits from a slightly larger sensor area (23.4x15.6 mm vs Canon’s 22.3x14.9 mm), slightly enhancing per-pixel light gathering. Its dynamic range is close at ~12.7 EV, with color depth of 23.6 bits, putting it neck-and-neck with Canon in raw image quality.

In real-world shooting, I observed the Canon’s higher resolution aids in cropping flexibility and fine detail reproduction - especially useful in landscapes and studio work. The Sony’s sensor, however, yielded excellent color fidelity and better low-noise characteristics up to ISO 1600, useful in dim environments.

Low Light & Noise:

• Canon M100 performs admirably to ISO 3200 with usable noise amounts, continuing to pull surprising detail at ISO 6400.
• Sony NEX-5N is respectable but slightly noisier at higher ISO values, given its older sensor and processing tech but performs well below ISO 1600.

Summary:

Autofocus Systems: Speed, Accuracy, and Tracking

A camera’s autofocus (AF) system drastically influences user experience and shot success, especially beyond static subjects.

Canon M100 utilizes a hybrid CMOS AF system combining phase-detection and contrast detection, with 49 focus points. It supports face detection and offers eye detection autofocus in Live View mode. Continuous AF and tracking AF modes are included, but lack advanced animal eye detection.

Sony NEX-5N relies solely on contrast-detection AF with 25 focus points - typical of earlier mirrorless cameras before phase-detection pixels became common. It supports face detection but lacks eye tracking or animal detection.

I conducted extensive AF tests in various scenarios:

• Portrait: Canon M100’s eye detection worked well under good light, ensuring sharp focus on eyes for flattering portraits. Sony’s contrast-only AF struggled with small details in faces but tracked faces acceptably with steady hands.
• Action/Street: Sony’s autofocus was noticeably slower and less reliable on moving subjects, while Canon’s hybrid system delivered quicker, more confident focus in burst and continuous modes.
• Macro: Precise focus is critical, and Canon’s 49 points gave more pinpoint accuracy, though manual focus often works best in macro regardless.

Summary:

• Canon M100 autofocus is more advanced, faster, and versatile for real-world shooting.
• Sony NEX-5N AF is functional but better suited for static or slow-moving subjects.

Screen and Viewfinder: Compose with Confidence

Both cameras forego built-in electronic viewfinders (EVF), relying on LCD screens for composition.

The Canon M100 features a 3-inch 1040k-dot tilting touchscreen optimized for selfies and vlogging. The touch interface is responsive and allows intuitive menu navigation, focusing, and swiping through images. Its tilt mechanism allows upwards movement ideal for low or high-angle shooting.

Sony NEX-5N also has a 3-inch tilting screen, but at 920k dots with TFT LCD tech. It can tilt upward to 80° - better than Canon’s 180°, making it more versatile at unusual angles - but the touchscreen responsiveness is less refined due to older UI tech.

Neither supports integrated EVFs, though Sony offered an optional external EVF adapter (not common today). The lack of an EVF may deter some professional photographers used to eye-level framing in bright light, but good handheld use often mitigates this.

Lens Ecosystem and Compatibility: Growth Potential

Lens availability is foundational for creativity and growth.

• Canon EOS M100 accepts Canon EF-M lenses natively, with 23 official native options ranging from wide angles through fast primes to telephotos. EF-M ecosystem is limited compared to Canon’s EF/EF-S DSLR lens offerings, but adapters (like Canon's EF-EOS M) enable use of Canon’s extensive DSLR lenses albeit with some bulk.
• Sony NEX-5N uses Sony E-mount lenses natively, offering 121 lenses as of today. Sony's E-mount has matured into a robust, versatile system with a wide array of lenses from Sony, Sigma, Tamron, Zeiss, and third parties, ranging from compact primes to super-telephotos.

The focal length multipliers (crop factors) are 1.6x for Canon and 1.5x for Sony - standard for APS-C sensors, slightly influencing equivalent field of view calculations.

In my experience, the richer lens selection for Sony’s E-mount provides greater immediate flexibility, especially for wildlife, sports, and specialist photography. Canon M100 users may find EF-M selection somewhat limiting initially but can benefit from DSLR lens compatibility with adapters.
