Sony Sony 16mm f2.8

ความคมชัดรอบขอบภาพค่อนข้างนุ่ม โดยเฉพาะเมื่อเปิดรูรับแสงกว้างประมาณ f/2.8–f/4 เนื่องจากความคลาดทรงกลม (spherical aberration) ความคมชัดไม่เพียงพอสำหรับการพิมพ์ที่ใหญ่กว่า 8x10 นิ้ว

ต้านทานแสงแฟลร์และโกสต์ได้ดีมาก เนื่องจากการออกแบบออปติคอลที่เรียบง่าย

• Extremely small and light — barely bigger than a body cap, at roughly 2.3-3.5 oz (65-100g), making a Sony mirrorless body genuinely pocketable for hiking and travel
• Fast, silent autofocus that turns a compact camera into an everyday carry that fits in a jacket pocket or hydration vest
• Low price, around $223-250 new and about $110 used, offering high value for its size
• Strong resistance to flare and ghosting thanks to its simple optical design
• The 24mm-equivalent field of view is versatile for landscapes, travel, and walk-around use

• Soft corners and edges, especially wide open between f/2.8 and f/4
• Optics that merely match the low price; not suitable for large prints
• Electronic 'focus-by-wire' manual focus ring with no direct mechanical connection, which only works when the camera is set correctly
• No focus or depth-of-field scales
• No Optical SteadyShot / image stabilization
• Real-world minimum focus distance feels longer than the listed 9.4 inches (closer to ~14 inches per one reviewer), with poor focus accuracy up close in low light

• Stop down past f/4 (toward f/8) to improve edge and corner sharpness, as it is softest wide open
• Use it for web, social media, and small prints rather than large reproductions
• Pair it with a body that has in-body stabilization since the lens has no OSS
• Treat its listed 9.4-inch minimum focus distance conservatively; expect closer to ~14 inches in practice and avoid critical close focus in low light
• Add the VCL-ECU1 converter if you want a wider 18mm-equivalent view from the same tiny package
