The cameras supporting this sensor can be smaller and usually cheaper, what is a nice benefit. Because this is a smaller sensor, it has a slight disadvantage in how much fine detail it can capture. That means the edges of the image captured by a full frame camera are cropped by the APS-C sensor. Full FrameĪ crop sensor is smaller than a full frame sensor. The two cameras I used are the Canon EOS 5D Mark IV (EN link) / (NL link) (launched Aug’ 2016) and the Canon EOS 77D (EN link) / (NL link) (launched Feb’ 2017).Ĭrop Sensor (or also called APS-C) vs. But of course we start with some important information. So I decided to show you the same lenses on the different sensors with my images so it’s more easy to understand. When I was searching for this topic I discovered a lot of technical stories with many numbers and that was a little boring to read. I’ll show you how the lenses act on both cameras because a 50mm on a full frame camera is not the same as a 50mm on a crop sensor camera. Hopefully by now you have a better understanding of the two main sensor types and can decide which is right for your photography.Many starting photographers don’t know the difference between a full frame sensor camera and a crop sensor (APS-C) camera, except for a huge difference in price. This is one of the reasons why you will generally find more noise in images taken at high ISOs with a crop sensor camera versus a full-frame camera.įull-frame cameras bodies like the Canon 5D MK IV are more expensive but also usually weather sealed whereas sometimes crop sensor bodies are not Summary Bigger pixels can capture more light and subsequently produce better quality images when you are faced with high contrast scenes or low light conditions. Whereas on a full-frame camera the pixels can be much larger. To fit 18 million pixels into a crop sensor the pixels would need to be much smaller and more tightly packed together. Let’s take two cameras (a full-frame and crop sensor) which both have the same resolution (i.e. This is the number of pixels in a given area. The first is what is known as “pixel density”. A bigger sensor has several major benefits. It may sound like all the arrows are pointing in the direction of crop sensors, but it’s not that simple. Photo by Gary Clarke - f/7.1 | 1/1250s | 300mm The case for full-frame sensors In other words if you are standing in the same spot and take a photo at exactly the same focal length with both a full-frame sensor camera and a crop sensor camera, when you look at the photo from the crop sensor camera, it will look like you have zoomed into the scene, even though you haven’t.Ĭrop sensors are a major benefit when you require a strong zoom for your subject, such as in wildlife photography. The biggest difference between these sensors are the size of them, but more on that later… In a practical setting, the big difference is the field of view that they can capture. This new film negative was 25.1mm x 16.7mm which is considerably smaller than a 35mm film. Which incidentally is why these days the most common crop-sensor size is called APS-C. The crop sensor also followed a previous film size which was created by Kodak in the 90s known as Advanced Photo System (APS). One of the biggest benefits of this was that many photographers who were shooting in film could simply swap to digital and still be able to use their lenses (some without even needing an adaptor). On DSLRs full-frame sensor is the same ratio as using a 35mm film (36 x 24mm), which made the switch to digital much easier for many photographers So basically, the full-frame sensor is the same ratio as using a 35mm film (36 x 24mm). When DSLRs were invented, this ratio of the traditional 35mm film was replicated as a digital sensor. This is still the case today with the 35mm film being the most widely used in analogue cameras. Back in the 1900s, the 35mm film became the standard for photographers as it struck a good balance between the cost of the film and the quality of the images it produced. But before we look at each and their respective pros and cons it’s important to understand their origins. A sensor that is known as “full-frame” and anything smaller than this sensor is referred to as a “crop sensor”. Cameras typically use two main types of sensors. These sensors are the heart of digital cameras and as such play an integral part in how a photo turns out when you press the shutter button. Pro photographers tend to opt for full-frame sensors while crop sensors are a goof affordable option to start with for beginners
