Wrong aperture and EV values for Olympus OMD E-M5 II #539

Open raduprv opened 2 years ago

Describe the bug

The EV settings look like this (from gphoto2 program)

/main/capturesettings/exposurecompensation Label: Exposure Compensation Readonly: 0 Type: RADIO Current: 0 Choice: 0 -5 Choice: 1 -4,7 Choice: 2 -4,3 [...]

When using gp_widget_set_value (child, str);, where str is for example "-4,7", it works erratically. The problem is that the values use "." instead of "," so the right value would be "-4.7" Same thing with the aperture values, and possibly others.

Name the camera Olympus OMD E-M5 Mk 2

The . vs , thing is floating point representation in your language setting. so itdepends which LANG is set if its komma or dot.

Yes, its a bit annoying.

Ok, but the camera returns the correct value when using gp_widget_get_value() I mean, it returns value such as 4.5 for aperture. gphoto2 (the program) shows me that widget with the wrong 4,5 value. Shouldn't it report what the camera returns?
