Key differences（核心区别）
- Aperture / light sensitivity（口径与感光能力）: S50 Pro (50mm) collects about 3× the light of S30 Pro (30mm), revealing fainter deep-sky objects faster. S30 Pro is lighter and more portable.
- Field of view（视场）: S30 Pro has a much wider telephoto field of view (4.6°) than S50 Pro (2.8°), better for wide nebulae and fast framing.
- Battery & storage（续航与存储）: S50 Pro has the largest battery (10000mAh / 9h) and full pro features; S30 Pro uses 6000mAh but is more compact.
- Pro workflow（专业功能）: Only S50 Pro adds mosaic/panorama, landscape freeze, constellation recognition, Plan mode, AI Assistant and remote control. S30 Pro is the lighter, more portable 4K option.
Which to choose（怎么选）
- S30 Pro — portable 4K: 1.65kg, 30mm aperture, 4K dual-lens (IMX585/IMX586), 128GB, 140×80×210mm. Great for travel and wide-field shooting where weight matters.
- S50 Pro — high-performance 4K: 50mm aperture for stronger light sensitivity, biggest battery (10000mAh) and full pro features (mosaic, panorama, AI Assistant, remote control). Best for serious deep-sky imaging.
