Why can't I get the camera to focus with the +4 and +10 filters?

I am not sure I understand what you are asking... the camera should focus, but only manually.

Are you close enough? Sometimes I need the lens to almost touch the subject.

What kind of lens are you using you may have to set the back focus. Or since this is a cheap adaptor it may be too thick for your camera

On my camera, I have to set the focal length and enable the exposure ring function when using this lens. Once complete, everything is automated but the focus.

With mine I have to be ridiculously close to the subject, like maybe an inch away. Try putting your lens closer and closer to what you're photographing until it is in focus before trying auto focus.

Focus and metering can be set for "spot". That was one of the settings I had to change when I was trying to take photos of the moon.

With this filter the camera does not auto focus or do the auto exposure correctly because this filter lets in so little light for the auto focus/exposure to work. The way I use it is to first get a exposure reading without putting on the filter. Then set an exposure using the manual setting (M) that is 8 to 9 stops higher to account for the filter (I decrease the shutter speed by 8 to 9 stops). I also at this point switch to manual focus (or auto focus without the filter and then set it to manual focus on the lens). Now I put on the filter and take the picture. Even though the filter is rated as 9 stops you may need to bracket manually between 8 to 9 stops to get the right exposure.

To my knowledge there isn't any way to manually focus these cameras. I bought mine as a refurbished unit and it has an incredibly clear image. You might have to contact Samsung.

I leave the i-Contrast turned ON. That might help. I also find when I use the ZOOM I need to give it a second or two to focus and then I can take the photo. Still learning too but love this camera!!!!

You need to zoom in pretty far to avoid the cutoff if you're using the lens shade. Not sure if it's RX10 compatible.

On the underside of the camera there are 2 screw adjustment slots (one for focus, one for zoom); please make sure your camera is in focus by adjusting both slots. If you still get blurriness problem, please use the button control on the camera to adjust the camera's color contrast and backlight setting (press on the button to bring out OSD menu, and then move up&down for choosing between menus, left&right for adjusting menus)

Specially, auto focus doesn't work. Always I have to set to f4.5-5.8, otherwise camera doesn't work. It is shOt lens.

No auto focus supported, try the Auto adapter for E-mount cameras.B00D9BKLX8

Did the focus lock? Make sure focus sensor is on something it can grab. Try manual focus to test mechanism.

On the D80 you have to prefocus before using the filter as the D80 has no live view and you cannot see anything with the filter attached, AF and metering do not work either. That required the camera be tripod mounted and all auto functions set to manual. It is much simpler to use it on a newer camera with live view mode such as a D7000.

I think you are right here. I don't believe it is a lens problem as I have see this problem across a couple of lens. I did two things that seem to make a different, the first was I completely reset all the camera setting and second thing I did was up grade the camera fireware from version 1.0. 4. to version 1.0. 9. This seems to have made a difference.

Will do if lens is of 58 mm thread (filter size is 58 mm), but will not focus correctly I observed, I can try and let u know

In general I think your best solution is to manually focus. Set the camera up, frame your shot, zoom in to the center of your frame, manually focus it, then zoom back out and verify your shot.
