 p.1 #10 · which cheap 50mm f1.2 lens for X-E5? | |

Not these two.
The only lens I have for the XE5 is the 23mm f2.8.
Would a 50 f1.4 do.? I suppose, if it were in the same price range, but I saw these first...
I know there are compromises, but if there is acceptable sharpness in the middle wide open, and across the frame by f8, I would be ok. Vignetting, coma, lateral and axial aberrations and AF that I am willing to compromise...

As you probably know, the super large aperture lenses (like the f/1.2 versions you mention) have two potential virtues.
1. They can, when used at the largest aperture, produce a very small depth of field. For some purposes, some photographers like that effect — for example in some approaches to portrait photography.
2. They can allow you to use a slightly higher shutter speed in very low light situations… if you are willing to accept that extremely narrow depth of field.
In both of those cases, there are issues to consider.
Regarding #1, while limiting depth of field (DOF) is useful, the extremely narrow DOF at f/1.2 and 50mm can be more limiting than necessary. For example, in a portrait with the head almost filling the frame, the if the eyes are in sharp focus the ears, hair, and tip of the nose may be out of focus! In fact, most often we don’t want to use such apertures for portraits, and f/1.4, f/2 or sometimes even smaller apertures can work well.
Regarding #2 (and here I speak as a person who does night street photography), while the small increase in light through the lens at f/1.2 can be helpful (it is about a half-stop), again the very narrow DOF is problematic in many shots. While I own several f/1.4 lenses that I use for this kind of photography, the great majority of my shots are at f/2.8 or f/4 for this very reason.
I’m unfamiliar with the two lenses you are looking at, so for specific information about them you’ll have to wait for someone else to reply. But were you aware that, according to another poster, that these are manual-focus-only lenses? No AF?
Of course, they don’t sound all the expensive, and if you have the money and want to play around with them, why not, I guess?
Good luck.
