SIOTI Adapter Ring Fit for SIOTI Filter Holder (77mm)

Love these little adapter rings. They work as designed in the Sioti system and for the price, you really cannot go wrong in my opinion.For those of you running Sigma lenses, I can confirm, they work perfectly; the threads on both the lens and the adapters run true and smooth.

Really impressed with the SIOTI brand, I already own the filter system this is intend for, this is not only much cheaper than my previous Cokin system but it also in my opinion of a much higher quality.

Great solid filter ring.. Fits perfectly

Does the job.

This I like I can only say try it it will not let you down

very good, fits perfect

I already had a Sioti filter holder which is great, but I needed a 77mm adapter ring for a different size lens. This ring is a really sloppy fit. Doesn't lock up with the locking thimble. Disappointed with it.

works as expected so far so good. Seems to be good quality.
