I can't find an answer regarding focal lengths. When I use a 16-50mm lens, it also shows focal lengths of 16-50mm. If I were to buy a new lens, do I have to convert the focal length from full-frame to APS-C or does the focal length correspond to what is shown on the display? Example: https://www.digitec.ch/de/s1/product/sigma-30mm-f14-dc-dn-c-sony-e-objektiv-5815726. Is the image detail on APS-C exactly the same as when I set 30mm on the camera?
