So as my question says in the title, does my crop sensor camera really turn my lens into a longer one (in terms of magnification), or does it just look like it based on the reduced field of view I get? The size of the image projected on the sensor is the same in both cases. But a smaller sensor with the same aspect ratio and same total number of pixels ...

FF sensor area (fxA)= 36x24mm= 864mm squared (^2), Any area of a given sensor can be represented by MP's as well as square mm Therefore, APS-C effective area (efA)= 24x16mm= 384mm^2 or possibly XMP (only as an example) FF crop factor for angle of view (cf) of lens is inversely related to the ratio of diagonal lengths of the rectangle made by the sensor ...

Yes. Compact cameras label their lenses in "35mm equivalent focal length" which is pretty illogical in my opinion. Thankfully other non-35mm formats such as m4/3 and APS-C and the various medium and large formats do not do the same. What this means is that your camera with its tiny (roughly 1/2.3" format [though that's not the actual measurement, just a ...

Michael's answer covers well how the area and dimensions of the two sensor sizes relate, but does not conceptually explain how or why that appears to affects focal length. I'll try to explain that. A lens designed for full frame 35mm (FF35) is designed to project a circular image large enough to cover a 36x24mm sensor / film frame. So what we have to ...

A word or two on crop factor: Over the years the camera has shrunk. As film evolved its resolving power improved and smaller film formats became commonplace. In the early 1900’s a still camera using 35mm motion picture film was introduced. The 35mm film format (image size) measures 24mm height by 36mm length. Millions of 35mm cameras were sold. Because of ...

Crop factor is expressed as a ratio of the linear measurements of a sensor compared to a 36x24mm 35mm film frame or a full frame sensor. This is because a sensor exactly half as large as another will also provide exactly half the angle of view as the other with a lens of the same focal length. Or conversely, a sensor half as large requires a lens of half the ...

Yes, this mean crop-factor of your camera (Samsung WB250F) is 6 Focal length is one of the ways to calculate crop-factor, divide 35 equivalent of focal length to the focal length on the lens P.S. The canonical way (as far as I know) is to use the size of the sensor and compare it with the size of fullframe sensor. Check here for reference
