I have heard 50 ft...but if you search the forum you might find a better answer
This video shows the lens being replaced but also goes over focusing

when I had my original 5004k , it was focused at about 5 feet. I refocused my pro lens at 4 feet, ( it was 1 foot) and it works well, I'm waiting for peau 8.25 lens, so i will ask them for proper focus distance
Would also help to be focusing on some 3D objects not just a flat surface.
A vase of flowers makes a pretty good target.

Here's what worked best for me:
Choose a scene outside which has objects that are about 5 feet away, 20 feet away and infinity, all in the same view.
Choose subjects that have a lot of texture such as brick walls, roofing on houses, concrete etc.
Best to have bright sunlight coming from the side to enhance texture, Don't shoot in late evening where high ISO noise will affect image.
Shoot in natural mode. Do not use gorgeous mode. it is over sharpened.
Place the H on a stable surface, no need to fly it.
If your lens is focusing too close, you will need to turn it clockwise.You will probably not have to move it more than 1/8"
Place a pencil mark on the lens mount and a series of marks 1/32" apart on the lens barrel adjacent to it.
Take a series of still shots using jpeg mode
Adjust the lens one mark between shots
Compare the shots side by side at full resolution zoomed in at 100%. Faststone viewer is great for this.
Find the image that is sharpest at 20 feet and acceptably sharp at 5 feet and infinity.
Set the lens to the mark that corresponds to that image,
Shoot another series with the lens set just before and just after this mark to see if they are sharper.
Take some shots at 1 foot away as well. if your lens is razor sharp at 1 foot, it is still focused too close.
Before cementing the lens, take some test flights and shoot stills and video which include subjects close and far out to infinity.
Good luck

Any photographer will tell you a few hours after sunrise or a few hours before sunset. Contrast allows the lines to be well defined. Just don't point into the sun, point away.
