#Apsc lens on frame full

If I bought two identical focal length lenses, one being an APSC lens and the other being a Full Frame lens, and mounted both on my camera. Lenses SPECIFICALLY made for APS cameras project a smaller 'image circle' and therefore may not work on FF cameras. If BOTH an APSC lens AND a Full Frame lens are listed as being a 16-55mm size, then what exactly is the difference between an APSC lens and a Full Frame lens? Cropping is more like using scissors around the edges. So my 16-55mm lens on my APSC sensor is in reality, about a 24-80mm lens, based on a crop factor of 1.5 or so. If I duct tape my 50mm lens to a cell phone, it's still a 50mm lens. The length is the length regardless of what camera you mount it on. They are not showing the base length based on the 35mm sensor. But apparently ALL lenses are listed at their mm length based on 35mm sensor (Full Frame). as I sadly discovered after I bought it (not that it would have changed my mind about buying it.). My (presumably) APSC 16-55mm kit lens that came with my A6100 is not TRULY a 16mm focal length. Now just to be clear, I understand the difference between an APSC sensor and a Full Frame sensor. If you have an A6100, then it's a Sony E mount. would they not look identical?Īnd could I mount my APSC lens on a full frame camera and get the full 16-55mm advertised length out of the lens? If BOTH an APSC lens AND a Full Frame lens are listed as being a 16-55mm size, then what exactly is the difference between an APSC lens and a Full Frame lens? If I bought two identical focal length lenses, one being an APSC lens and the other being a Full Frame lens, and mounted both on my camera. Then I read that you can mount a Full Frame lens on an APSC sensor camera, and the camera simply crops the image down to the 1.5 to fit the sensor. I'm a bit confused about the difference between an APSC lens and a Full Frame lens, I can't even tell which type of lens I have on my A6100 (its the kit 16-55).
