轉接環

Wasn't sure this 40.6mm to 43mm adapter would thread cleanly, but it screwed onto my old lens without any wobble. My filters now fit like they were made for it.

Finally a way to use my old filters on the new lens setup without buying everything over again. The 43mm threads screw on smoothly and it sits flush, no wobble or light leaks so far.

Was worried my older 40.6mm lenses would be useless after upgrading filters, but this adapter screws on perfectly and the threads feel solid. Now I can use my whole filter collection again instead of rebuying everything.
