Issues (?) with my K3ii

Let me be brief:

1) I was just at a family party and I gave my aunt my camera to take pictures. She likes taking pictures but doesn't know anything about settings so I just put it in Tv mode and fix shutter at 1/180 so she doesn't get any blurry pictures. I have the flash on (Metz 50 AF-1) at PTTL at -2.0 EV just to fill shadows. I further have the in-camera at +0.7 EV because I like bright pictures. The idea was that the camera controlled the aperture and ISO correspondingly. All the shots were done at ISO 100 and very underexposed. Why? I have the ISO at 100-3200. What settings could affect this?

2) When I half-press the shutter button it focuses as it should, but sometimes it doesnt? Some times (not always) no matter how many times I half-press it won't focus and I have to press the AF button and then it focuses. Why is this?

Thanks.

Sounds like your 16-50 is starting to fail with it's SDM. You can always get the lens to convert to screwdrive if you find it being intolerable. Here is a thread that may help as well.

Auto ISO?

Sorry for delay in response.

The ISO was not in auto, it was fixed at 100, hence the outcome described above. In order to put it in auto I had to press ISO button and then the green button? I found this out by searching the forum. Why is there no menu-setting controlling this?

In regards to focus I will be looking into converting it to screw-drive I guess. The person I got this lens from said the SDM motor already failed and he had it fixed/replaced through warranty. Is it common for the SDM to fail after fix?

Auto-ISO is controlled via the info button menu on the K-3II, but there is also the aforementioned shortcut combination.

Before I finished reading all the posts... I had thoughts that you are not using auto-ISO... hence you get the underexposure result... but I would go for full manual mode when using flash. Regarding the second problem you experienced, I can only say that it is possible that SDM motor fails.... I have both DA*16-50 and DA*50-135 lenses, I have no problem since the SDM motors were replaced. And I don't them as often, when not being used, I store them standing up (front element down) in the pouch. I never have any problems since then.
