In Topic: GoPro to YS Adaptor / Clamp?

31 March 2015 - 11:18 AM

I've got a INON Focus Light which is mounted to my tray via a YS Mount (like the Nauticam cold shoe one)

 

When I'm doing WA video, I was thinking of mounting a GoPro to the same mounting point, however I can't seem to find a GoPro mount to a YS Mount - does such a thing exist?

I have the GoPro attached to the cold shoe on my NA-GH4 via a loc-line adapter on the cold shoe side, and a tripod mount with loc-line on the GoPro side.

I am not sure I understand the logic but you have replaced the zoom with the function keys and now using the knob for focus?

 

Yes. The result being an IL stabilized 14-42 lens, with full zoom control. With the flip diopter you should have a slightly better setup as the Oly 12-50 is not stabilized and no other mid-zoom lenses allow for manual focus (behind a flat port).

thetrickster, how is the gearing for manual focus? How many full turns of the knob does it require to move across the full range of focus?

 

Interested in how the focus is going too. My guess though is that since the focus is electronic with this lens, it's similar to the zoom control in the focus changes in either direction with a slight twist of the knob in either direction.

In Topic: Red gel on underwater video light

26 February 2015 - 02:51 PM

Anyone have any experience shooting with red gel on video lights during night dives? The idea being of course to avoid annoying wildlife and limit those pesky larvae that like the lights so much. Any advice on specific gels to use will be gratefully accepted.

 

This topic came up here before (in 2014 I think) and I was also interested in this - someone said they were going to do a test. I know on land at least, the closest I can get to a correct white balance with red light is somewhere in the yellow spectrum. I'm thinking this might also require some kind of filter on your lens as well to get back to white. Not sure if this will slow things down too much or push ISO to high..
