Using frame lens on crop sensor1/31/2024 ![]() Make sure to check the compatibility of your lenses with your crop sensor camera before using them. ![]() If you are using a lens designed for a full-frame camera on a crop sensor camera, you may experience vignetting or other issues. Crop Sensor Lens ConversionĪnother thing to keep in mind is that not all lenses are compatible with crop sensor cameras. For example, if you have a 50mm lens and are using a camera with a crop factor of 1.5x, the equivalent focal length would be 75mm (50mm x 1.5). The easiest way to do this is to multiply the focal length of your lens by the crop factor. ![]() If you are used to shooting with a full-frame camera and are transitioning to a camera with a smaller sensor, you may wonder how to convert your lenses to match the new field of view. For example, Canon crop sensor cameras have a crop factor of 1.6x, while a 1/2.3 sensor (commonly found in smaller sensor point-and-shoot cameras) has a crop factor of approximately 5.6x. Keep in mind that crop factor can vary depending on camera manufacturers and sensor size. So, the crop factor for a Sony camera with an APS-C sensor is 1.84x. To calculate the crop factor, simply divide the full-frame diagonal size by the APS-C diagonal size:Ĭrop Factor = Full-Frame Diagonal Size / APS-C Diagonal Size Crop Factor = 43.3mm / 23.5mm Crop Factor = 1.84x The diagonal size of an APS-C sensor is approximately 23.5mm, while the diagonal size of a full-frame sensor is 43.3mm. For example, let’s say you have a Sony camera with an APS-C sensor. To calculate crop factor, you need to know the size of your camera’s sensor and the size of a full-frame sensor. This means that a 50mm lens on a crop sensor camera will have a field of view equivalent to a 75mm lens on a full-frame camera with a crop factor of 1.5x. When you use a lens on a crop sensor camera, the crop factor “crops in” or zooms in on the image compared to what you would see on a full-frame camera. For example, a crop factor of 1.5x means that the diagonal size of the camera’s sensor is 1.5 times smaller than the diagonal size of a full-frame sensor.Ĭrop factor is important because it affects the field of view of your lenses depending on which digital camera you choose. It is a number that represents the ratio of the diagonal size of a camera’s image sensor to the diagonal size of a full-frame sensor. What is Crop Factor?Ĭrop factor is a term used to describe how much smaller crop sensors are compared to a full-frame sensors in a modern digital camera. ![]() This means that when you take a photo with a crop sensor camera, the image is “cropped” or zoomed in compared to what you would get with a full-frame sensor. A crop sensor, also known as an APS-C sensor, is a type of image sensor used in some digital cameras.Ĭompared to a full-frame sensor (which has the same dimensions as a 35mm film negative), a crop sensor is smaller. What is a Crop Sensor?īefore we dive into crop factor, let’s first define what a crop sensor is. But what exactly is crop factor, and how can you calculate it? In this blog post, we will go over everything you need to know about crop factor in photography and how to calculate it. As a new photographer, you may have heard the term “crop factor” thrown around when discussing different camera bodies and lenses. ![]()
