But at 11 mm the lens will likely have a lot more distortion issues than a 16mm lens. To get the 16mm focal length, the crop frame sensor will have to use close to 11mm natural focal length lens. On a crop-frame sensor, however, the same lens offers a widest focal length of 24mm. Let us consider the example of a 16-35 lens.Ī focal length of 16mm provides great coverage for architectural shots, and for shoots in cramped spaces. Lesser distortion than a crop-frame lens is another huge advantage. Wider Focal LengthĪ full frame camera offers a wider focal length more easily. For any given lens and settings, the depth of field of a full frame lens will appear truer than the crop-frame sensor for the same reason. This reduces the natural gradation of focus in an image as it crops a part of the gradation while the full frame sensor gives a natural gradation. The effective focal length in a crop-sensor is more than the original focal length. But 5D Mark III can provide good quality images even at ISO of 3200, while 550D starts dropping drastically above 800. For example, the dynamic range of Canon 550D and Canon 5D Mark III (crop sensor and full frame respectively, released close to each other) are 11.7 and 11.6. The full frame sensors tend to provide far better image quality at higher ISOs. But the same technology has touched the full frame cameras too.Ĭombining the above two factors provides us with the real incentives of using a full frame sensor. Again, in 2019, the crop-sensor cameras have gone way ahead of their predecessors in dynamic range performance. Hence, a more versatile camera is available. The larger the sensor size, the better the dynamic range. Imagine a cloudy day with all the drama, or a white model wearing black clothes.ĭynamic range is one factor that is proportional to the sensor, while also being related to the processor. For photographers, a high dynamic range is important to capture dynamic scenes where very bright highlight, as well as dark shadows, are present. Higher Dynamic Rangeĭynamic Range is the difference between the darkest and the lightest portions in an image. Sony has, in fact, brought a revolution with crop-sensor cameras, most of them being mirrorless. The difference between the previous generation of full-frame cameras and the present generation of crop-sensor cameras has thinned owing to the advancement of technology. However, modern-day crop-frame sensors show amazing high ISO or low-light shooting capabilities. For the professional wedding, landscape, and architectural photographers – this comes in really handy. The larger the sensor size, the better the high ISO performance. One of the biggest benefits a full frame sensor has is better ISO performance. The Traditional Benefits of Full Frame Sensor The Better ISO Performance The smaller digital cameras carry a crop-factor of up to 5. There are also cameras with a crop factor of 1.3 from Canon. The actual reason isn’t that the crop-sensor frame has a larger reach, but the sensor can’t capture the entire image projected by the lens, and it gets “cropped”, hence appears more zoomed in.Ĭanon’s traditional crop-frame sensors carry a crop factor of 1.6. The effective focal length of any lens attached to a DX body is 1.5 times the actual focal length, or focal length on an FX body. While FX is a full-frame sensor, DX is a crop-frame sensor. What Is a Crop Sensor in a Camera?Ĭrop factor refers to the ratio of the 35mm sensor size to the crop-frame sensor. When DSLR’s came, the same sensor size of 24mm x 36mm became standard, until the smaller sensors came, which came to be called the crop-sensor cameras. The size of the images captured with the film was 36 mm x 24 mm, and the width of the film was 35 mm, which became the common terminology. Why does the size of the sensor take center-stage in most camera debates? Is it the most important, or the only thing that matters while buying a DSLR? What is a Full Frame Camera Sensor?įull frame, or 35 mm sensor, as it is called, is actually the size of the film used in the SLR days. They are also considered more professional and provide better results overall. It is also an important criterion for buying DSLRs for many photographers.įull frame cameras are costlier and traditionally bulky. The topic of full frame vs crop sensor is a debate that has surpassed most of the famous camera models. Download Free eBook: 25 Techniques All Photographers Should Master
