Fotodiox 매크로 익스텐션 튜브 세트 Pentax K (PK) 마운트 SLR 카메라용 극단적 근접 촬영

I was worried the lack of glass would degrade image quality, but my Pentax lens actually looks sharper than with my old close-up filter. The set lets me fine-tune magnification by mixing the three tubes, which is perfect for getting tiny details on coins.

They click together and apart in seconds, so swapping configurations in the field is p

I was able to get sharp close-ups of a flower's stamen without any added weight, since the set uses no glass. The tubes clicked together solidly on my Pentax K-50, and the ability to mix and match lengths is perfect for experimenting with magnification.
