it is said that full frame aperture equivalent of 2.8 to aps-c is 4.2. does it mean that shutter speed of aps-c is one stop slower that full frame on the same aperture? given the same focal length equivalent e.g. aps-c 23mm and ff 35mm.

> If you put a 50 mm lens at f3 on a full frame sensor and take a picture from 10feet away from your subject with the background 10 feet behind your subject. And then take the same photo with the same lens, but now set at F2, on a crump sensor, and you want the same framing you will have to
I only commented on your " There’s no such thing as aperture equivalent. " as being false as it is.
Thus the context is 50/3 on FF and 33/2 on APS-C. In this context the apertures are equivalent, thus your statement was false.
