What is the Image Sensor Size of the Samsung WB750?
Optical sensor size is one of the most important factors affecting the image quality produced by a digital camera. Compact digital cameras have smaller optical sensors due to the reduced space available in the camera body. Digital SLRs and Mirrorless interchangeable lens cameras (MILCs) have large optical sensors to achieve maximum image quality.
A larger optical sensor produces better quality photographs. A 4/3" sensor size has a 2x crop factor compared to 35mm film, while a 1/4" sensor size is significantly smaller and will result in lower quality images.
