• Bright, high-resolution touchscreen for accurate framing
• Touch AF and focus peaking available, aiding manual focus accuracy
• Overall more pleasant user experience for reviewing images and video

For enthusiasts who value precise focusing and composition, the YI M1’s superior screen technology offers a palpable advantage. The TG-320’s screen is functional for casual use but feels limited quickly.

Autofocus and Focus Control: Speed and Accuracy Across Genres

You won’t find fast or complex autofocus on the TG-320 due to its compact shooter design, while the YI M1 offers an 81-point contrast-detection AF system geared toward more deliberate, accurate focusing.

• TG-320: Contrast-detection AF with face detection, single AF with no manual focus - suited for stationary subjects or snapshots. Continuous shoot rate fixed at 1 fps limits freeze-frame applications.
• YI M1: 81 AF points with touch AF, face detection, single and continuous AF modes, and manual focus rings on lenses. Up to 5 fps continuous shooting, supporting more dynamic subjects.

In wildlife or sports scenarios requiring quick focus tracking, the TG-320 is inadequate. The YI M1, while not pro-grade AF speed, provides acceptable performance for entry-level mirrorless standards - better suited for portraits, street, and casual wildlife shots.

Lens Ecosystem and Interchangeability: Exploring Creative Possibilities

The TG-320’s fixed 28-102mm equivalent zoom at f/3.5-5.1 is suitable for general snapshots but lacks flexibility or specialized lenses.

Conversely, the YI M1's Micro Four Thirds mount opens access to over 100 lenses, including primes, macros, telephotos, and ultra-wide options, allowing photographers to tailor to:

• Portraits with fast-aperture primes for creamy bokeh
• Landscapes with sharp ultra-wide lenses
