Great deal for the price - make sure to F-stop high enough,
This review is from: Zeikos 52mm 4 piece high definition Close-Up filter set (+1, +2, +4 and +10 Diopters) Magnification Kit - Metal Rim, includes deluxe case (Electronics)I ended up with these when trying to purchase a different filter set that was within about $11, $12. Without any photo examples at the time I was looking at the product page, I was unsure what to expect.
First off, I doubt the filters are multi coated (they reflect white light when looked at. Green would be multi-coated.) But a good multi-coated filter would probably cost more.
The black paint looks like it will flake off eventually.
Those shortcomings aside I found the quality to be surprisingly sharp. I plan to post a few test photos to show off what these filters are capable of. I can get sharp enough to see the wing scale texture on butterflies and the pollen on flowers. CA distortion and fringing is to be expected. At +10 the fuzziness was really bad with the lens F stop at 1.8 to about 4. Setting it to F8 or slightly higher appears to greatly sharpen and improve the overall effect of the filters, especially the +4 and +10. I have not yet tried to layer the filters to increase magnification, but I'd expect the quality to drop when adding more glass in front of the lens.
I have at times combined one of these filters with an extension tube and found the effect to be pretty good, though it does narrow the depth of field and make getting a perfectly focused image a bit more challenging.
Are these better than extension tubes or a macro lens? Most likely not, but in a pinch or a limited budget, these may do pretty well.
