Having personally tested and used thousands of cameras over the last 15 years, including extensive shooting evaluations and measured laboratory tests, I am well positioned to dissect the technical aspects, user experience, and real-world performance here. This comprehensive comparison will cover sensor technology, autofocus, ergonomics, optics, video capabilities, and genre-specific use cases. Whether you are a travel photographer, aspiring portrait artist, or a video content creator on a budget, this analysis will help clarify which camera fits your objectives best.

Getting Acquainted: Size, Handling & Ergonomics

Understanding the physical feel and control layout directly influences shooting comfort and operational efficiency in real scenarios, especially during extended sessions or dynamic conditions.

Sony RX100 II:
One of the defining features of the RX100 II is its truly pocketable form factor - measuring just 102 x 58 x 38 mm and weighing 281 grams, it is designed for maximum portability without compromising a large sensor. Its compact body, made primarily of magnesium alloy, feels solid and resilient yet fits snugly into a jacket pocket or small purse, making it ideal for travel and street photography where discretion and lightness matter most.

The ergonomics take a minimalist stance with limited physical controls, as expected in a fixed-lens compact, but a well-designed grip and subtly textured surfaces aid one-handed operation. The lack of an integrated viewfinder necessitates reliance on the rear LCD or optionally adding an external EVF accessory.

YI M1:
In contrast, the YI M1, an entry-level mirrorless camera with Micro Four Thirds (MFT) mount, is larger and heavier at 114 x 64 x 34 mm, 350 grams without lens, reflecting the demands of interchangeable lenses and its rangefinder-inspired styling. This size increase affords availability of more external controls and a more substantial grip, contributing to stability especially when paired with larger lenses.

Despite having no built-in viewfinder, the M1 has a fixed, non-tilting 3-inch touchscreen LCD serving as the primary interface, which influences how photographers compose and interact with menus.

The above image shows the difference in top-plate control density and tactile feedback mechanisms; the M1 provides more dedicated dials suitable for quick exposure compensation and mode switching, while the RX100 II relies on compact dial and button combinations optimized for one-handed use.

Sensor and Image Quality: Size, Resolution, and Performance

Sensor size fundamentally affects noise levels, dynamic range, and bokeh capabilities. Hence, we dive into a direct comparison of sensor specifications, their impact on image fidelity, and low-light performance.

• Sony RX100 II uses a 1-inch type Exmor CMOS sensor with dimensions of 13.2 x 8.8 mm covering an area of approximately 116.16 mm² and offers 20 megapixels of resolution. The sensor is paired with an anti-aliasing filter and a max native ISO of 12,800, expandable to 25,600, which was remarkable for a compact from 2013. The sensor's DxOMark overall score is 67, with highlights in color depth (22.5 bits) and dynamic range (12.4 EV), indicating good tonal gradation and highlight retention, albeit with some noise penalties at higher ISOs. Optical image stabilization helps maintain sharpness in handheld low-light shooting.

• YI M1 boasts a larger Four Thirds sensor (17.3 x 13 mm, approx. 224.9 mm²) also with a 20-megapixel resolution, producing maximum images sized at 5184 x 3888 pixels. The sensor's theoretical advantage lies in increased light gathering capacity and improved dynamic range potential due to the bigger sensor area - almost doubling the RX100’s sensor real estate. It offers a native ISO range of 100–25,600. While DxOMark scores are unavailable, Micro Four Thirds sensors typically achieve superior noise control at mid- to high ISOs and better dynamic range compared to 1-inch sensors from this generation. No built-in stabilization means image sharpness depends strongly on lens choice or tripod use.

In practical testing, the RX100 II produces crisp, detailed JPEGs directly from camera and decent RAW files, excelling in daylight conditions with vivid color rendering. The YI M1 benefits from larger sensor size in nuanced shadow recovery and cleaner noise profiles at ISO 1600 and above, which is especially valuable in landscape and indoor portraits.

Displays, Viewfinders, and User Interface

Shooting experience is heavily influenced by the quality and versatility of the LCD and viewfinder systems, especially in bright or complicated lighting conditions.

The Sony RX100 II features a 3-inch tilting Xtra Fine WhiteMagic TFT LCD with a resolution of 1229k dots. While not touch-enabled, the screen tilts upward roughly 90 degrees, enabling low-angle or self-portrait composition - though the RX100 II lacks selfie-specific features.

The YI M1 also has a 3-inch LCD monitor but fixed in position and with a marginally lower resolution of 1040k dots, compensated by touchscreen capabilities. This touchscreen feature is a major usability plus, enabling tap-to-focus, menu navigation, and image review intuitively and quickly. Unlike the RX100 II, the M1 lacks an electronic viewfinder and relies solely on the LCD, which may hinder some photographers in bright daylight or critical manual focus work.

Neither camera includes a built-in EVF, but the RX100 II supports an accessory electronic viewfinder, appreciated for steady compositions during intense outdoor shooting.

Autofocus Technology and Continuous Shooting

Fast and accurate autofocus (AF) systems are critical for genres like wildlife, sports, and street photography. Let's place side-by-side the autofocus capabilities and burst shooting performance.

Despite using contrast-detection AF systems, the RX100 II offers a relatively fast 10 fps continuous shooting rate, beneficial for capturing fleeting moments in street and sports contexts. Its AF tracking and face detection function reliably in good light, but struggles somewhat in low contrast scenarios due to the lack of phase-detection sensors.

The YI M1 provides a higher number of AF points at 81, improving the compositional flexibility of AF point selection. Touch-to-focus capability enhances ease of use. However, continuous shooting caps at 5 fps, less efficient for rapid action scenes. Tracking AF and live-view AF operation are supported but less precise compared to modern hybrid systems. Both cameras lack animal eye detection, limiting utility for dedicated wildlife photographers targeting animals’ eyes.

Lens Systems and Accessories: Fixed vs. Interchangeable

Lens selection profoundly affects photographic possibilities - from ultra-wide landscapes to macro and telephoto wildlife shots. Here the two cameras diverge sharply.

• Sony RX100 II: Comes equipped with a fixed 28-100mm equivalent zoom lens (3.6x zoom). The fast aperture starts at ƒ/1.8 at wide-angle, narrowing to ƒ/4.9 telephoto, facilitating shallow depth-of-field and decent low-light capture in wide focal lengths. This lens allows close focusing distances of about 5 cm for pseudo-macro shots but obviously limits further optical versatility.

• YI M1: Utilizes the Micro Four Thirds system mount, unlocking a vast ecosystem of 107 native lenses from Panasonic, Olympus, and third-party makers. This opens possibilities for specialized optics: ultra-sharp primes, macro lenses, super-telephoto zooms, fisheyes, and professional-grade zooms. Absence of built-in image stabilization means lenses with optical IS or body stabilization coverage become key to maximizing sharpness.

The interchangeable-lens approach of the YI M1 significantly broadens creative scope, though it trades off portability and immediate convenience of the fixed-lens RX100 II.

Low Light and Noise Performance

Low-light shooting remains a major challenge for many photographers. Let's gauge noise performance and image usability in dim conditions.

Due to the larger sensor area, the YI M1 inherently exhibits better signal-to-noise ratios, producing cleaner shadows and retaining fine color gradations at ISO 1600 and beyond. Despite lacking in-body image stabilization, pairing with stabilized lenses can mitigate camera shake.

The Sony RX100 II, while having superior lens aperture at the wide end (ƒ/1.8 vs. M1’s standard kit lenses), benefits from optical image stabilization (OIS), improving handheld low-light usability. However, its smaller sensor produces more chroma noise at elevated ISOs, which becomes noticeable above ISO 3200.

This makes the RX100 II adequate for casual night or event shots; however, the YI M1 provides more latitude for higher-quality night photography when tripod or stabilization aids are available.

Video Capabilities: From Full HD to 4K

Video remains a major evaluation criterion for hybrid shooters and content creators.

In this domain, the YI M1 offers a clear advantage with its capability to record true 4K video (4096 x 2160) at 30 frames per second, a notable feat for an entry-level mirrorless camera from 2016. This is augmented by a larger sensor with superior low-light potential, delivering cinematic video quality directly from the camera. However, the absence of built-in image stabilization means handheld 4K capture risks noticeable shake unless using stabilized lenses or gimbals.

The aging Sony RX100 II is limited to Full HD (1080p) at 60 fps and lacks 4K capability. Its optical image stabilization helps smooth video, making it a decent option for casual video shooters, but intrinsic codec limitations and lack of microphone ports restrict advanced audio control.

For those prioritizing video content, especially at 4K resolution, the YI M1 is the superior pick, provided you accept the need for external stabilization solutions.

Battery Life, Storage, and Connectivity

Endurance and data handling underpin practical shooting workflows, especially on long outings or professional gigs.

Sony RX100 II:

• Uses the NP-BX1 battery rated for approximately 350 shots per charge (CIPA standard).
• Has a single slot for SD/SDHC/SDXC or Memory Stick Duo cards.
• Connectivity options include built-in Wi-Fi and NFC for rapid image transfer to mobile devices and remote control, though Bluetooth is missing.

YI M1:

• Provides longer battery life at 450 shots per charge, beneficial for full-day shoots.
• Single SD card slot supporting SDXC.
• Features built-in Wi-Fi and Bluetooth but no NFC. Wireless transfer and remote control are enabled via the dedicated YI app.

While neither camera supports USB power charging, it is noteworthy that the YI M1 combines longer battery endurance with better wireless ecosystem integration, facilitating modern connected shooting workflows.
