SensorĮquivalent focal length for Micro Four Thirds You can download our crop factor calculator or focal length multiplication factor here – crop_factor_calculator.xslx Focal length comparison chartįocal length comparison chart or focal length comparison tool helps to convert and compare same focal length on various different sensor sizes. The crop factor can be used to multiply the given focal length to calculate equivalent focal length. A new, full-frame camera comes with a hefty price tag of about 3000. Another difference worth considering is the cost. So, if you use a full frame and a crop sensor to take images from an identical distance, with the same lens and point of view, the latter will produce a tighter FoV. This is because the smaller the sensor the higher the focal length appears. The smaller sensor’s FoV is a crop of the full frame. The same factor is also known as focal length multiplier factor. The name crop comes from the fact that the image is “cropped in” compared to complete available image smaller sensors. The factor by which the given sensor is smaller or larger compared to a standard full frame sensor is known as crop factor. As you can see, a standard 35mm full frame sensor captures a wider image while a smaller crop sensor gives a narrower image and it appears to be zoomed in. The term Image distance in below images is also known as focal length.īelow image explains this phenomenon. The lens can see this angle and sensor will capture anything that falls within this angle of view.Īs you can see the smaller the focal length, the wider the angle of view and the longer the focal length the smaller the angle of view. ![]() The light rays coming from the scene and converging at a point inside the les for a an angle. The smaller focal lengths are known as wide angle and the longer lenses are known as telephoto. In practice photography lenses have focal lengths are in the range of 10 to 600 mm. The distance between the point where light rays converge inside the lens and the image sensor is known as the focal length.įocal length can theoretically go from zero to infinity. The lens captures the light and send it to the sensor. Lets see all these aspects of focal length comparison in detail. The focal length itself ( this is generally referenced to the standard sensor size), the angle of view and the crop factor. When you want to do focal length comparison there are three main things to take into consideration. ![]() Focal length comparison : What are important aspects ? You can also read about shutter speed comparison chart here. Before going into the detail of the focal length comparison tool, lets understand some key concepts behind it. It is an essential tool to select the right lens for the purpose.ĭifferent focal lengths offer different angle of views and different perspective as well. Focal length comparison chart is something used to compare focal lengths for various camera sensor sizes. ![]()
