While I preset my touch AF on something well lit 6-10' away before launch, it is not intended as an infinity focus. It is intended as a hyperfocal distance that includes infinity. Subtle difference, but important. Once set, I switch the touch function in GO 4 (ver. 4.0.0) over to exposure, so as not to accidentally reset my focus, while turning off the still incessant High Wind Warnings, by touching them on the screen in the upper left. I have no need to reset the focus for the duration of the 23 minute flight video, even if I land in complete darkness. Personally, I would prefer the same fixed focus of the P4 on both the Mavic on the P4P. On night flights, I use a flashlight on the focus point to set the initial focus within that 6-10' distance. So far, it's worked well for me.
Thx so much Gadget Guy! I went totally to Infinity in Manual Gadget Guy. And all my focus problems are gone. And I agree on the fixed focus deal too. Who can rack focus on this thing from 6-10ft as your flying? And as wide as the lens is it's not gonna be drastic Depth of Field anyway.

My only reason for not using an infinity setting is that on most regular lenses, the infinity setting is actually past infinity, and must be racked back for an accurate infinity. I assumed that the P4P lens was similar, but I may be mistaken. Mainly, I want a fixed infinity focus set before launch (so as not to have to stop in flight), and from my screened-in open top helipad, the farthest distance available with good contrast is about 10 feet away on the ground without opening the screen, which seems to still be tack sharp throughout my flights, even at infinity at f/2.8. I use the legibility of the small print on distant billboards and clear separation of parallel pier pilings a mile away as the measure of ultimate sharpness, when examining individual video frames.
Thanks! I'll give it a try. Not having to prefocus before every launch would be a big help!
Yellow icon is the targeted exposure setting. When you touch the screen, it will use where you touched for the exposure, rather than the center. Default autoexposure is in the middle. Press on the X in the corner of the yellow spot meter circle to hide it or retouch the center of the screen to recenter it and hide it automatically.
