طقم حلقات فاصل بصري لمصحح التليكومبريسور (A5025SET)

Finally, a spacer set that actually lets me dial in the exact backfocus my camera needs — the threads are smooth and precise. Used it with my reducer setup and stars look perfectly round across the whole frame now. Small investment for a noticeable improvement in image quality.

These rings fit perfectly into my imaging train, and having the extra set of spacers made dialing in the exact back focus for my camera a breeze. The threads are smooth and the anodized finish looks great on the rig.

The spacing adjustment on these rings is exactly what I needed for my camera sensor combo, and the fit was precise with no wobble when threaded together. Swapping them out only took a couple of minutes, and my star shapes are noticeably sharper now.
