Peephole (Door View) Camera

Ok got the lens in. Works great without a peephole (that zoom!), but having some issues. There is significant aberration and halo from light sources and bright objects. I also cannot seem to get the image in perfect focus but this might be a side effect of the former. I don’t understand this because when using a cell phone for example, the camera can see perfectly fine through the peephole and has no focus issues. I assume this has something to do with the aperture but am unsure.
As a side note, 25mm is a liiiittle too much zoom. Maybe a 16mm or 20mm.
