VivitarClose-up 52mm +1/+2/+4/+10 Lens Set VIV-CL-52 | 52mm Filters for Digital Cameras and DSLR Cameras, Macro Lens Kit for Canon Cameras, Vivitar Cameras, and More (4 Piece Set), Black

Makes close up shots on the ace pro more visually appealing. Action cameras have hard time focusing on objects within certain ranges so this eliminates that problem.

Great for getting the closer focus using an aftermarket filter holder for the Insta AcePro camera. Start with the least magnification, and then go up if still not in focus. Everyone holds the camera at different distances when they vlog. So keep that in mind. ONE of the filter magnifications will work for you!

Llegan rapido y en perfectas condiciones, tienen una funda de una calidad aceptable, sirven bastante bien si el enfoque es manual, son lentes de cristal. Lo unico malo es que los arillos son de metal pero se despintan con facilidad.

GOOD

TLDR, they're mediocre. Not a bad purchase for $20, and certainly useable, but they also certainly have issues.I primarily got these to use on my GoPro 10 with a 3rd party cage that allows 52mm filters to be attached. My intended purpose was really just to experiment with the ability to adjust the focus of the GoPro's fixed-focus lens. They do cause background blur, but the in-focus area is very close to the camera - around 20-30cm, and it's hard to tell what's in focus while filming so I probably won't use them for this purpose.I also tried them on my DSLR, where I found many lens+filter combinations had issues focusing on anything at all. My closest minimum focus lens, an 18-55mm that can focus as close as 0.25m, had the best results. It was able to work with the +10 filter, to get maybe 15-20% closer to the subject, and it seemed to yield a slightly shallower depth of field. This is proably the best case scenario.The optical quality of these lenses isn't great. They are very reflective, so while you can screw in more than one to combine their effects, if there's any light source pointing towards the lens you get ghosting and glows and flares very quickly. They have a pretty significant warping effect around the edges, which is clearly visible even with the fisheye wide lens setting on the GoPro.The photo of the back of my pocketwatch against my computer screen shows that while it can enable closer focal distance, the highlights can cause ghosting quite easily; weirdly the bottom left of the pocketwatch has been washed out the most by the highlight in the top right. In the photo of the funky water bottle you can see the warping more clearly, and you can see the significant image defects caused by the lens reflectiveness in a backlit shot. Both of these were stills taken from GoPro footage on linear mode, so there's no fisheye warping from the GoPro itself. Photos from my DSLR with the macro filters were less impacted by these defects.
