Vivitar Series 1 +1 +2 +4 +10 Close-Up Macro Filter Set w/Pouch (52mm)

GOOD

These Close up Filter use only on Manual Mode .not auto mode ...

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.

buen producto, apenas empiezo en la macro foto, hice algunas pruebas y todo en orden, tal como marca la propaganda

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.

As the manufacturer suggests, these lenses work well for photographing flowers (when they bloom) and insects (when they smile). I have tested these close-up lenses with a Nikon AF-S DX Nikor 18-55 mm 1:3.5-5.6 G VR lens (the type supplied with many Nikon camera kits). This lens is fairly versatile, and it can focus to within approximately 6” of a subject even without close-up lens attachments. (Other cameras have lenses with 52mm threads which can accommodate these close-up lenses.)Setting the camera lens at its longest focal length (and greatest degree of magnification), with a +1 close-up lens a 2” subject will fill the camera viewfinder; with a +10 lens 1.5” subject will fill the viewfinder. The magnification with the other close-up lenses falls within these extremes. With a fixed focal length lens of normal focal length (circa 42mm) the degree of magnification with these close-up lenses will be slightly less. These close-up lenses can be used in combination for greater magnification, but any lens used in combination with the +10 lens must be attached to the back of the +10 lens.If you have been into photography for some time, especially in the pre-digital years, you may have a large collection of 35mm slides. Making digital copies of such slides confers many advantages. They can be leveled, and/or cropped, and their brightness, contrast, color, and sharpness can be modified. Thus, in some cases, the image on a digital copy may be a vast improvement over the original slide. And, being easily reproducible, multiple digital copies of an image can be assembled in separate groups relating to family, to travel, to art work, etc. Digital images can easily be shared with friends and family members. Various commercial slide copiers are available, varying widely in cost. But if you want a challenge, you can make a slide copy stand with which these lenses will work well. (See photographs.) I have copied slides with these lenses and find they give good results, with no loss of sharpness across the resulting digital images.

Using with a Nikon basic kit lens 18-55 plus a slide copying attachment to hold the film. They work extremely well for this. The image quality is great, their value compared to buying a macro lens is (price a new Nikon macro len)! Easy to use just screw in and the filters themselves their quality is fine. Been a professional since the 80's and a very pleasant surprise.
