SL3 AF in dark?

I thought I asked this before but couldn't find the thread.

The camera has real difficulty focusing on subject in near dark conditions. Looking through viewfinder and it's totally dark. At an outdoor event last night and focus was having trouble picking up something to focus on. I think Nikon had a mode that had a focus assist "light" that helped with focus. Does the SL3 have that?  Maybe I need to bring a flashlight😁.

I was using a hand held flash. A bunch of my shots were pretty soft. Maybe manual focus and small aperture  is my friend in this case.

Sorry if this has been asked before.

The SL3-S has. I have never used it, but it's always the first thing I switch off!

I know there was that pption on the Nikon D800/850. I never used itt. Maybe an old miners helmet with a headlight would help.

Have you checked the manual?

i though most AF assist beams from cameras were infrared?

Well this was disappointing.

I had a chance to try out the AF lamp assist and it is pretty useless or I’m doing something completely wrong.

First the lamp location on the camera. With a 24-90 lens on camera, the “beam” is obstructed by the lens. So in the viewfinder you only see illumination in the upper left portion of frame. In order for it to work, you have to move the focus square to that area. This is made worse if the lens shade is on.

This is not really workable but I was hoping. Maybe with a smaller lens like an M lens or a short in lenghth prime this could work. There probably isn’t anywhere on the SL3 that this assist could be placed for it to work properly. Maybe above the Leica name on housing?

Struck out on this one Leica🙁

You need light to photograph regardless of film or digital.  You can't expect a camera to focus in the dark.

I dislike the death ray effect that these focus lights have. Although they are popularly labeled IR in my experience there is little Infra present, nor are they very effective with most cameras and certainly not by Leica. My favourite technique is to focus on stronger contrasts and lock. Beam off. LiDAR would be better. But that can damage fellow photographers sensors.

Are you shooting with flash or long exposure?

If you’re shooting with long exposure, I expect you have a tripod. In that case, I would use enhanced live view and manual focus. It works great for astro.

I dislike the death ray as well as it may advert people/animals that they are framed, so i have it 99% off.
Also the range ist not really very long but it works rather well for near objects and can be helpful.

Not really sure what would be helpful, a flash with a focus lamp what switch off when you push the trigger, most underwater flashes have that.
You may do a search if there are some hand held focus lights for underwater photography, i believe that they existed once and they are much stronger than the in-camera or in-flash ones.

My Godox V1 have two systems for that, a automatic light what switch on when camera has troubles to focus and a 1 second continuous strobo effect what is thought to show shadows. I did not used either as i use the flashes almost exclusively for macro photography.
The above would work for rather near objects, but most likely not for distant sceneries.

Otherwise focus manually or use hyperfocal settings to have most possible in focus.

My other concern about LiDAR, at least the way it's implemented in the X2D2, is that the sensor is very close to the lens mount, and the lenses are very large. I doubt it can see much of the scene.

Panasonic has a LiDAR implementation with DJI which is mounted in the hot shoe. I have no experience with it, but it's more likely to have an unobstructed view of your subject.
