Focus issue with Nikon DSC D3500

[esavolle]

Hi,

I'm testing the new Nikon DSC D3500 with gphoto2 2.5.17 / libgphoto2 2.5.17

When using the focus mode AF-A or AF-S, the camera freezes with message on the display "Connected to smart device". It is working with the DSC D3400.

I have made several tests with capture-and-download and trigger-capture, varying the focus mode and the capture target (RAM or internal SDCard) for both the Nikon DSC D3500 and D3400.

The logs are quite big due to capture-and-download so i join them with links

d3500.zip d3400.zip

gphoto2-version.txt

If more tests are needed please just ask.

Btw the USB id for the Nikon DSC D3500 is:

Nikon DSC D3500

usb:v04B0p0445* GPHOTO2_DRIVER=PTP ID_GPHOTO2=1

Can Confirm this problem with the D3500. Any focus mode other than manual causes the camera to lockup.

May be the same issue as #350

First image capture fails to complete. Second image capture takes two images, and completes successfully

The fault alternates between those states. I've attached log files without image data.

D3500-FirstCapture.txt D3500-SecondCapture.txt

In shell mode, the fault only occurs on the first capture, subsequent captures behave correctly.

Any resolution on this? I'm having the same issue running Raspbian Jessie Lite on a Raspberry Pi, except my camera is definitely on Manual Focus and I'm still experiencing the issue.

Confirming the issue as well, just ran over it. Here's a fun little thing I found:

• Set any auto focus, Open console, run gphoto2 --capture-image Process will freeze, camera display will show "Connected to smart device". Camera will focus, but it will never capture.
• Open new console, run any command (like reading a config). Command will not succeed, because PTP device is busy.
• Close the old (frozen) console. Camera display will still be showing "Connected to smart device".
• Run a command like reading a config in the new one, command will succeed. The device is no longer busy, display message on camera goes away.
• Run --capture image again, same thing will happen.

But here comes the really weird part: If the first command you run in the new console after closing the frozen one is --capture-image, The camera will immediately respond... and capture two images!

we are basically doing the exact same thing as on the D3400, just the cameras never goes "non busy". In current git I abort this busy wait after 5 seconds, but I dont think it will help much.

@msmeissn is this problem fixed now? or still persists I'm facing same issue with my DSLR D3500 Camera.

Facing the same issue (first no capture at all, then 2 at the same time), I found a method to capture photos correctly.

• Once the D3500 is powered, run gphoto2 --capture-image. The focus is made, and the capturing process is running but it never ends.

• Kill the process twice (by pressing "Ctrl+c" twice or by serching and killing twice the gphoto2 process' pid in another console (pgrep gphoto2, then kill )).

• The capturing process should be over. Now run gphoto2 --reset. (I lack informations on what the command actually resets but hey, it works.)

• Run gphoto2 --capture-image, it should work fine and capture a single photo every time the command is used until the camera is powered off, then you will have to repeat the process.

I have the same issue as mentioned above. Is this something I'm doing wrong, something gphoto can do or a problem on Nikon's end? Any updates on the progress of a fix for this or an alternative software I can use?

Try --trigger-capture command instead. It works on a D3500.

Try --trigger-capture command instead. It works on a D3500.

This actually seems to work with Nikon D3500, with continuous captures

gphoto2 --trigger-capture --wait-event-and-download=CAPTURECOMPLETE
