This filter adapter does the job very well! It is made of metal, so feels not inferior to. Also it can be properly screwed onto the lens thread, no hooks or clamps, works very smooth. Just when screwing the filter onto the adapter - no jamming, the filter can be screwed properly. Have already tried with all my filters, and had no problems. The small overall height (approx 4mm protrude forward over the lens addition), the adapter also not visible on the photos taken (at 18mm) - he would continue to apply, it could happen even provided that you can see it in any way. But so, no problem and therefore also suitable for wide angle.
In short - I am very zufreiden and may issue a strong buy recommendation! So you can attach its large filter problems even on smaller lens diameters ...
