Lately, I have been photographing a few bull moose in the willows. No problem. After I get an ample supply of a shot when they are just feeding away, I switch over and take a few videos of the same scene.
But, I am not sure how to set the focus for video. If left to auto focus, the lens jumps or zooms in and out a bit with the wind blowing the willows. Just to get some good video, I changed back to photo mode, focused on the moose, changed the lens back to manual focus, then changed to video and Live View and recorded the scene. It works okay until the moose moves out of the focused plane.
I only quickly scanned the manual on video back in March and haven't spent that much time with the feature, so any quick advice is appreciated.
Hi again, I should have mentioned I am usually shooting with a 200-400 mm, so the depth of field isn't that great, especially when zoomed to 400mm. I am usually in the F/8 to F/11 in aperture mode already. If they step two or three feet forward, they can easily go out of critical focus.
Any additional advice will be appreciated. I'll review the manual some more, too.
Hi Pete, Thanks for the response. That's what I was afraid of based on my limited experience. I dragged the D4 manual out of my bag tonight and planned on reading up on the video features. I kept thinking I was missing something.
With wind blowing the grass and willows around the moose, I couldn't find a setting that would hold on the moose subject except in manual focus.
Does anyone know of a way (or device) that can remotely (untethered) 'refocus' (e.g. activate the AF-on button) for movies on the D4?
For example, can I use a wireless remote shutter release such as the Vello FreeWave Plus Wireless Remote Shutter Release - 2.4GHz (for Nikon)? It says it can work up to 320' to "Press Shutter Halfway to Focus".
