hether compact or DSLR, without sensors a camera is no more than a box. A sensor not only converts an optical image into Wan electronic signal it also enhances photography experience and the quality of the image. There are two types of camera sensors: CCD and CMOS. CCD (Charge-Coupled Devices) Sensor: It offers superior image quality with better dynamic range and noise control. This is being used in almost every point- and-shoot and Digital SLR cameras. CCD sensors produce high quality images but tend to be more expensive and consume more power than CMOS. CMOS (Complementary Metal–Oxide–Semiconductor): It has been considered as an inferior competitor to CCD, but with the latest innovations in the CMOS technology, it has been upgraded to match and even transcend the CCD standard. CMOS sensors are more sensitive, produce higher quality images and consume lesser power in comparison to CCD. It works more efficiently and performs better even in high-speed burst modes with built-in functionality than CCD sensors. New developments in CMOS: Numerous sensors are available in the market based on CMOS technology such as Foveon X3 sensor that is being used only in Sigma’s compact cameras and DSLRs. Leica, Olympus, and APS-C Sensor: Most of the major camera Panasonic are using Live MOS image sensors in the Four manufacturers use this sensor in their DSLRs. It comes in Thirds System DSLRs that they’ve been manufacturing 23.6 by 15.8 mm size, but different sizes are also available since 2006. These sensors are producing CCD image quality with APS-C sensors including 2.2 by 14.8mm, 23.5 by with the lower power consumption of a CMOS. 15.6mm and 23.7mm by 15.6mm, etc. Four Thirds Sensor: As name suggests, it is almost a Sensor sizes quarter (17.3 by 13mm) in size of a full-frame sensor. This Full-frame Sensor: 36 by 24 mm is the largest size of the open DSLR standard sensor created by Olympus and Kodak sensor that called full-frame sensor. It is similar to the and being used in both companies’ DSLR cameras. With frame of 35mm film. It eliminates the crop factor, meaning the 2X crop factor, it has double effective focal length of a whatever you see through the viewfinder, the camera mounted lens. captures exactly the same. Full-frame model with a larger CX Format Sensor: The 13.2 by 8 mm sensor sensor can deliver extremely shallows depth of field when introduced in the year 2011 and adopted by Nikon and paired with wide aperture lenses. These are the best Sony. Nikon 1 and Sony Cyber-Shot DSC-RX100 used the CX choice for macro and video work. format sensor that comes with 2.7X crop factor. APS-H Sensor: APS (Active Pixel Sensor) is the most Small Sensors: There are two small size sensors: 7.6 by popular sensor type for both interchangeable-lens and 5.7 mm and 5.76 by 4.29 mm. The 7.6 by 5.7 mm sensor is higher-quality fixed-lens cameras. With the 28.7 by 19 mm among the largest sensor sizes used in compact cameras size, this sensor is present in a vast portion of consumer and 5.76 by 4.29mm is among the smallest sensors, and prosumer DSLRs. typically used in low-priced point-and-shoot models.
