Hi everyone, just wanted to share my test with you regarding the "sweet spot" of the new Phantom 4 Pro 1" sensor 20 Mb lens. Sweet spot is refering to F-stop in a lens that produce sharpest or "most focused" picture outcome. As you can see from the fist picture I did a test with all f-stops that this lens can do both in automatic focus and manual focus mode. Typically in traditional photography with DSLR or mirrorless camera lenses the sweet spot it somewhere around F8-9 or close to that points, where lowesr and biggest f-stops are the softest, BUT...
if you look that the chart I made, f2.8 is not the softest one, but rather to my suprise I can't see real difference in sharpness from f2.8 up till f6.3 then at f7.1 focus get softer and at f11 is the softest. Also on the second picture you can see that I belive is a app's UI mistake in icons. The designer must mixed up macro and infinity icons, because typically you get the sharpest results in infinity manual lens focus setting, but here it's vise versa. Ok see for your self and I hope this small test will help you in your video or photo productions. Let me know what do you think. Fly safe
