What this adapter ring does

The Urth 86-39mm adapter ring connects an 86 mm threaded lens to the 100 mm square filter holder system. It is built for photographers who want to use square filters on lenses with that specific thread size.

The thread size that decides fit

The ring accepts an 86 mm male thread on the lens side and fits the 100 mm holder on the filter side. If your lens has a different thread diameter this adapter will not work.

Mounting and common issues

True threads make attachment straightforward; the ring screws on and aligns with the holder without tools. The matte black finish cuts reflections. Over-tightening can bind the threads, so stop when the connection feels firm.

Questions about this item

What does the 86-39mm designation mean when I mount this ring on my lens?

The 86mm side threads onto an 86mm lens front; the 39mm side accepts the 100mm square filter holder, letting you use square filters on that lens.

What thread standard does the 86mm side follow, and does it limit filter choices?

It uses standard 86mm camera filter threads, so any 86mm-threaded lens fits; the 39mm side is specific to the 100mm square holder system.

How much clearance does the ring need in front of the lens to fit and mount?

The slim alloy ring adds minimal depth; its matte black finish prevents reflections while the true threads ensure secure attachment to the 100mm holder.
