Thanks Jason for your input.
Do you feel the 3.97mm lens was sharper than the stock one you replaced it with on the Hero?
I don't know if my lens is just out of focus from the factory, or if it is a bad (soft) lens overall. Due to the QC issues DJI seems to have (First two of mine had manufacturing issues and were exchanged.), no doubt these are set up on a jig and not individually tested for focus or rushed if they are.
Hello gmack
I'll tell you my experience, got the p4, bought peau lens , thinking quality of image would be better.
1.- focusing the lens right was a pain in the butt, needed to make different photo test in order to achieve the right focus.
2.- after being successful on this I have to say the quality of image was exactly the same but more narrowed.
3.- I found a big big problem on peau lens, they always blur a little of the image on the left and right edges of the screen, more on the left side tho. This is very annoying, and I couldn't find a way to get rid of it but just on still photos, during video recording was impossible to get rid of it.
4.- one would think because they are 16mp they will perform better right? FALSE, reason being is because the quality is also determined by the sensor and guess what, the p4 sensor can't read more than 12mp , so in other words , you are stuck to 12mp resolution.
5.- the way they are attached to the camera is not like original phantom lens, meaning originals go in very very tight, you need to put a lot of pressure and force to be able to move them when you are focusing.
The peau lens only hold their focus position through a black soft plastic ring, which doesn't not hold the position of focus perfectly as with movement and time they end up going out of focus again!!!.
Conclusion:
Stick to the original lens, stay away from peau lens, no image quality improvement, in fact you will en up with blur image results on video in the edges.you will loose focus on time, meaning having the need of focusing the lens again over and over.
Save your money. and your time.
They are trash.
( sorry for my English is not my natal language lol) safe flying to you!
