I just switched from Canon 7D to Oly OMD. Really like the versatility of the camera, but also got some glitches from my previous experiences with it as well.
The housing I own is Nauticam. The problem is that, when I want to switch from shooting stills to video mode, I just push the recording button. This would trigger the video recording function of the camera; however, the problem is that the aperture & shutter speed settings do not follow into the video mode. More specifically, It looks like pushing the video recording button would record the video using the "P" mode with average exposure metering. For example, I always shoot stills with underexposed ambient so the subject would be emphasize and lit by strobes, but when I hit the recording mode, the water suddenly become much lighter blue with a very pale subject.
For now, the only way for me to manually configure the exposure of the video is to turn the dial wheel of the camera to its designate video capturing mode, which is a bit troublesome.
Is there an easier way to switch from shooting stills to video capturing while retaining the setting from 'M' mode of the camera?
By the way, here is the footage of a thresher shark taken with OMD using the P? mode.
