Learned something new (to me at least) about the TAP. You can put the f/stop set on the lens in the EXIF (2.0 - 8.0) in addition to the focal length AND maintain the correct exposure. You do this by using exposure compensation. Set the aperture on the camera the same as on the lens, then compensate accordingly by dial or menu:
f/2.0 = 0, f/2.8 = -1, f/4.0 = -2, f/5.6 = -3, and f/8.0 = - 4 . F/8.0 has to be done in the menu while the first three can be done on the top dial or the menu. You can also interpolate. F/11 @ -5 exposes correctly and puts the aperture in the EXIF but it resets the EXIF focal length to 15mm unless you remap it via the Android app.
If you are new to TAP, note the difference between setting the f/stop set on the lens and setting it on the camera.
