The crop factor is a critical parameter when comparing Full Frame and APS-C sensor cameras, representing the ratio of the dimensions of the camera’s image sensor to that of a Full Frame sensor. In the context of APS-C cameras, the typical crop factor hovers around 1.5 , signifying that the APS-C sensor is 1.5 times smaller than its Full Frame 1"-type sensor. Type 1 (12.7 x 9.5mm) sensor. We will quote sensor area in comparison tables, as it's the difference in imaging area that has the biggest impact on image quality for single-shot photography, and we believe area is the more intuitive way of conveying the magnitude of sensor size difference. A crop frame sensor is a sensor that has smaller dimensions than that of a 35mm film frame. The size difference between a crop and full frame sensor can vary, but the crop will always be smaller, hence the name. Since the camera and lens of a crop sensor is smaller and lighter, they can be less expensive than the other options available. That actual meaning of this 1.6 crop factor is only that your 55-250 mm lens on the cropped sensor body has the same field of view as a camera with full sensor would see with a 88-400 mm lens (because its sensor is larger, seeing a wider view, so needing a 1.6x longer lens to reduce the full frame field of view back to what the smaller sensor Many people often question full-frame sensors to crop sensors, wondering if full cameras are better for videos. Full sensors have lower noise, megapixels, and capture more light. Unfortunately, cameras are missing both the 4k and 1080p resolution, and that is where the real issue begins with sensors featuring higher MP than what the videos need. Ortiz shot the full frame camera at f/2.8 to capture a similar depth of field to shooting the crop sensor camera at f/1.8 — the exception was the night photos, for which Ortiz used f/1.8 to keep It means that a 50mm lens on a crop sensor camera has an equivalent field of view to a 75mm lens on a full frame camera (50mm x 1.5 = 75mm). Bear in mind; this is just an approximation. Canon’s crop factor is actually about 1.6x, and most Nikon and Sony cameras are normally closer to 1.52x. If you’re curious about the exact crop factor of With this, the full frame vs crop sensor debate began. Furthermore, because a crop sensor is smaller than the full frame sensors it introduces a crop factor into your photos. Meaning if you use a full frame lens on a crop sensor camera you will notice the whole image you see through your viewfinder will be outside the square of your lens. The 1.4x TC makes the 600mm, an 840mm on a full frame camera, so in theory this allows my full frame camera to shoot wildlife with nearly the same zoom factor as a crop sensor. (Nikon crop sensors are 1.5 and Canon, 1.6) There are two things to consider when looking at a new lens: First is its ease of use. Second is the quality of its optics. Posted December 13, 2011.

"Full frame" refers to the sensor size being the same (approximately) as a 35mm film frame, or 24mm x 36mm. "Crop Sensor" cameras have a sensor that is smaller than 24mmx36mm. Your 400D has a sensor 14.8mmx22.2mm, and is often called "APS-C", in reference to a similar frame size available with the (nearly, if not pCkRj.
