Vivitar Series 1 +1 +2 +4 +10 Close-Up Macro Filter Set w/Pouch, Black, 6.7 x 3.6 x 1.2 inches, (VIV-CL-37)

Maybe not the same quality as a dedicated macro lens, but these give me the opportunity to experiment (and decide whether I want to invest in that lens). I find that I use the +2 and +4 the most often: +1 doesn't get me enough of a close-up effect, and the depth of field on +10 is so narrow that it's tough to get a reasonable amount of detail in focus.

I used the +1 and +2 adapted onto a trail camera to get really nice close-up videos of birds and other critters coming to my water tank. They work great. Most of the time, the +1 is just right.

I like the 4x and 10x the others not useful.

I attached to my vintage Polaroid with an adaptor. Used a 10x and a 2x stacked and the results looks so pretty!

Individually, and partially stacked these lenses are great. If you stack all 4 consecutively with the 10x on the outside I get a black ring around my subject. I doubt that much magnification is really needed, but it is worth mentioning. That is also on a JVC Everio HD camcorder. Other cameras may or may not have that happen. I am extremely happy with my purchase and can't wait to get some more use out of them.Item arrived on time and was exactly as described.

Even though I generally prefer two-element "achromatic" close-up lenses to the single-element type sold here, for the low price (and some nostalgia for the name...;-), I bought them in the 37mm size to try on some of my lenses. At "smallish" apertures (f10-f18), the +4 worked very well on my Panasonic 12-32mm and the +10 worked very well on my 14-42mm PZ lenses. Result: good "macro" performance with very little additional weight, size, and expense...--DR

The 1, 2 and 4x lenses are decent, increasing magnification without much issue. The 10x on the other hand is next to impossible to focus anything at a distance, but does provide a nice macro.

Good product to extend the close-in working range of a lens in a pinch, but will not overcome basic design limitations of less expensive lenses. These simply let you get a little closer to the subject. If you think you may be serious about macro photography you might start saving for a dedicated solution.
