Hi Marcus,

thank you for your research.


So my new findings are=E2=80=A6

First: I tested the same setup on a linux desktop computer with recent
linux mint. Tried both USB2 and USB3 connections. The resulting durations
with USB2 were about 14secs, with USB3 they varied between about 8 and 12
secs. So quite similar to the raspberry but the variations with USB3 were a
bit strange.

Second: In the cam was an almost empty 128GB sd card (speed 300MB/s). I
changed to an empty 16GB card (speed 80MB/s) and guess what, the process
got much faster. Between 4 to 5 seconds on both systems (Pi and desktop).
Here is the log for that setup with the 16GB sd card
<https://drive.google.com/file/d/1LNbtFDDu7hM7tdHchZN1cEp1_-yyV09I/view?usp=
=3Dshare_link>
.

I tried a third thing: Capturing without a sd card in the camera.
Thought it might work =E2=80=93 because it does with the canon D7 =E2=80=93=
 but it gave me=E2=80=A6
*** Error ***
PTP Store Not Available
ERROR: Could not capture image.
ERROR: Could not capture.
The log for this process without sd card
<https://drive.google.com/file/d/19VXbzPFH4MLpP_pX7ijnMzf_eLpqekKx/view?usp=
=3Dshare_link>
.
Is it just not doable with the G9?


*The SD card is definitely a huge factor for the process duration.*


Best wishes,
Alex

Most ops take long on camera side, which could be generally the camera<br>
or USB speed.<br>
<br>
If this was just tested on PI , can you cross check on a regular<br>
computer/laptop too if it takes as long?<br>

&gt; &gt; &gt; &gt; &gt; &gt; Hi Marcus and all,<br>
&gt; &gt; &gt; &gt; &gt; &gt; I now have a G9 and tested it with gphoto2.<b=
r>
&gt; &gt; &gt; &gt; &gt; &gt; Autodetect recognizes the G9 as a GH5.<br>
&gt; &gt; &gt; &gt; &gt; &gt;<br>
&gt; &gt; &gt; &gt; &gt; &gt; --capture-image-and-download works but the pr=
ocess takes about 13<br>
&gt; &gt; &gt; &gt; seconds.<br>
&gt; &gt; &gt; &gt; &gt; &gt; With the 7D it only takes about 3 or 4 second=
s.<br>
&gt; &gt; &gt; &gt; &gt; &gt; Do you have any idea if the process could be =
sped up?<br>
&gt; &gt; &gt; &gt; &gt; &gt;<br>
&gt; &gt; &gt; &gt; &gt; &gt; Actually the captured image gets written on t=
he pi after about 6<br>
&gt; &gt; &gt; &gt; seconds.<br>
&gt; &gt; &gt; &gt; &gt; &gt; But then the process takes another 6 to 7 sec=
onds to delete the<br>
&gt; &gt; file<br>
&gt; &gt; &gt; &gt; on the<br>
&gt; &gt; &gt; &gt; &gt; &gt; camera or do something else. When I add --kee=
p to the command it<br>
&gt; &gt; is the<br>
&gt; &gt; &gt; &gt; &gt; &gt; same. About 6 seconds to get the image on the=
 raspberry and<br>
&gt; &gt; another 6<br>
&gt; &gt; &gt; &gt; to 7<br>
&gt; &gt; &gt; &gt; &gt; &gt; seconds doing something else.<br>
&gt; &gt; &gt; &gt; &gt; &gt;<br>
&gt; &gt; &gt; &gt; &gt; &gt; I attach the logfile for coming from *env LAN=
G=3DC gphoto2 --debug<br>
&gt; &gt; &gt; &gt; &gt; &gt; --debug-logfile=3Dmy-logfile.txt --capture-im=
age-and-download*<br>
&gt; &gt; &gt; &gt; &gt; &gt;<br>
&gt; &gt; &gt; &gt; &gt; &gt; It would be really cool if the time could be =
minimized somehow.<br>
&gt; &gt; &gt; &gt; &gt; &gt;<br>
&gt; &gt; &gt; &gt; &gt; &gt; Best wishes to all<br>
&gt; &gt; &gt; &gt; &gt; &gt; Alex<br>

&gt; &gt; &gt; &gt; &gt; &gt;&gt;<br>
&gt; &gt; &gt; &gt; &gt; &gt;&gt; if I get a G9 I will write about my findi=

&gt; &gt; &gt; &gt; &gt; &gt;&gt; I tested a GH6 via USB. It gets detected =
and can take a photo but<br>
&gt; &gt; the<br>

&gt; &gt; &gt; &gt; &gt; &gt;&gt;&gt; &gt;<br>
&gt; &gt; &gt; &gt; &gt; &gt;&gt;&gt; &gt; I am quite new to gphoto =E2=80=
=93 first impression: it&#39;s quite<br>
&gt; &gt; awesome!<br>
&gt; &gt; &gt; &gt; &gt; &gt;&gt;&gt; &gt;<br>
&gt; &gt; &gt; &gt; &gt; &gt;&gt;&gt; &gt; Testing it out with a Canon 7D e=
verything worked perfectly.<br>
&gt; &gt; &gt; &gt; &gt; &gt;&gt;&gt; &gt; But I am planning on buying a Lu=
mix G9.<br>
&gt; &gt; &gt; &gt; &gt; &gt;&gt;&gt; &gt; Unfortunately the Lumix G-Series=
 is labeled as &#39;experimental&#39;<br>
&gt; &gt; and I<br>
&gt; &gt; &gt; &gt; &gt; &gt;&gt;&gt; &gt; couldn&#39;t find much informati=
on on it.<br>
&gt; &gt; &gt; &gt; &gt; &gt;&gt;&gt; &gt;<br>
&gt; &gt; &gt; &gt; &gt; &gt;&gt;&gt; &gt; Has anyone some experience with =
gphoto2 and the Lumix G9?<br>
&gt; &gt; &gt; &gt; &gt; &gt;&gt;&gt; &gt; Does &#39;gphoto capture-image-a=
nd-download&#39; work?<br>
&gt; &gt; &gt; &gt; &gt; &gt;&gt;&gt;<br>
&gt; &gt; &gt; &gt; &gt; &gt;&gt;&gt; The Lumix I used for development did =
not do capture over USB, but<br>
&gt; &gt; &gt; &gt; only<br>
&gt; &gt; &gt; &gt; &gt; &gt;&gt;&gt; over WLAN.<br>
&gt; &gt; &gt; &gt; &gt; &gt;&gt;&gt;<br>
&gt; &gt; &gt; &gt; &gt; &gt;&gt;&gt; I sadly do not remember if capture ov=
er USB works, I did add the<br>
&gt; &gt; code<br>
&gt; &gt; &gt; &gt; &gt; &gt;&gt;&gt; though.<br>
&gt; &gt; &gt; &gt; &gt; &gt;&gt;&gt; I think preview at least worked.<br>
&gt; &gt; &gt; &gt; &gt; &gt;&gt;&gt;<br>
&gt; &gt; &gt; &gt; &gt; &gt;&gt;&gt; I dont have the camera available here=
 though.<br>
