The first one sent to me had some small chips out of the glass on the 10X.
When trying to clean the replacements and compare them with the original I can see how absolutely horrible the glass is.
Each filter in both packs is riddled with small nicks and scrapes (I’m not talking microscopic level, this is really just inexcusable).
Having said that, I guess the saving grace here is that the way the focus works I have yet to see any of these defects present in the photos taken.
NOTE:I would strongly suggest you do not attach these directly to your lens.The threading on these is not at all precise, do NOT strip your threading on your expensive lens. Use some good fitting protective filters between these poorly made things and your nice expensive lens. (so glad I did)
If you have $450, get a real macro lens. If you have only $20-$30, this will suffice.
Here’s two photos from my Nikon D90 with an 18-105 lens and the 10X filter:
