EOS R6 Mark II vs α6700
قراءة جنبًا إلى جنب لـ sensor size.
فهم sensor size
Sensor size dwarfs almost every other camera spec for image quality.
Common sizes (smallest to largest)
- 1/2.5" – 1/1.3" — smartphone sensors. Area: 24–58 mm².
- 1" — premium compacts, top phones (Xiaomi 14 Ultra). 116 mm².
- Four Thirds — Panasonic, OM System. 225 mm².
- APS-C — Sony, Fujifilm, Canon mid-tier. 332–370 mm².
- Full Frame (35 mm) — 864 mm².
- Medium Format — Fujifilm GFX, Hasselblad. 1,452 mm².
Practical effect
Each step up roughly doubles light capture. A full-frame at ISO 6400 looks like an APS-C at ISO 3200 or a Four Thirds at ISO 1600.
Depth of field
Larger sensors give shallower DoF at equivalent framing — the "creamy bokeh" look. Phones simulate this computationally; results vary.

ما هو sensor size؟
The physical area of a camera's image sensor. Larger sensors gather more light, deliver less noise, shallower depth of field, and better low-light performance. The single biggest determinant of image quality.
