Digital Camera Sensor Sizes: How it Influences Your Photography
This article aims to address the question: how does your digital camera's sensor size influence different types of photography? Your choice of sensor size is analogous to choosing between 35 mm, medium format and large format film cameras — with a few notable differences unique to digital technology. Much confusion often arises on this topic because there are both so many different size options, and so many trade-offs relating to depth of field, image noise, diffraction, cost and size/weight. Background reading on this topic can be found in the tutorial on digital camera sensors. Sensor sizes currently have many possibilities, depending on their use, price point and desired portability. The relative size for many of these is shown below: Canon's 1Ds/5D and Nikon D3 series are the most common full frame sensors. Camera phones and other compact cameras use sensor sizes in the range of ~1/4" to 2/3". The crop factor is the sensor's diagonal size compared to a full-frame 35 mm sensor.
