However, smaller sensors do see a smaller cropped view from it than a larger sensor would see. Low light doesn’t have to equal low quality with these tips for successful nighttime photos. If the lens is 150-600 mm, it is ALWAYS 150-600 mm. Discover how adjusting shutter speed can help you capture clean shots or motion-filled moments. The Equivalent Focal Length ONLY applies to the full frame camera. It does NOT apply to your cropped sensor body. If you don't have experience with full frame cameras, then this Equivalent Focal Length has no meaning to you. Photographer Ilko Alexandroff created a comparison between APS-C body and a full frame body, using 85mm and 135mm lenses on both. It can sound abstract in theory before you actually see the results. Knowing these differences is important because it can help you decide what kind of camera is right for you. The purpose of this Equivalent Focal Length merely tells them what field of view to expect from the new digital camera with the smaller sensor, in full frame terms that they understand. A camera with a crop (APS-C) sensor and the one with a full frame sensor give different results with the same lens. Crop Sensor VS Full Frame Cameras What’s the Difference There are a few key differences between full frame cameras and crop sensor cameras. Users with years of experience with full frame 35 mm film cameras know the field of view expected from various focal lengths. Equivalent focal length is a comparison which corresponds to the lens, due to sensor size, but it only applies to the full frame sensor body. A smaller sensor simply crops a smaller view.Ĭrop factor is about the sensor size, and it is about the field of view, but crop factor is NOT about the lens. The lens does what it always does, and the sensor size sees what it always sees. The "Equivalent Focal Length" only apples to the full size sensor. the only issue is that a cropped sensor size sees a smaller field of view. The field of view is also determined by the sensor size. 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 would see). It has been said that "your 55-250 mm has the same field of view as a 88-400", but that is very incomplete which causes us confusion if said that way. What does change is that the body with a smaller sensor sees a smaller field of view, because the smaller sensor crops the view to be smaller. The sensor size cannot affect what the lens actually does, but a smaller sensor can only see a smaller crop of it. If it is a 150-600 mm lens, it is always a 150-600 mm lens on any camera body. Crop factor does NOT affect the lens in any way.
