37mm to 52mm Filter Adapter

This step-up ring lets photographers mount 52mm threaded filters onto lenses with 37mm filter threads. It bridges the diameter gap so a single filter size can serve multiple lenses, reducing the number of filters a kit requires.

Threaded Interface Constraints

The ring adds a small amount of length between the lens front and the filter glass, which can increase the chance of vignetting on wide-angle lenses at their shortest focal lengths. Stacking additional adapters or thick filters compounds this effect and may block the lens hood bayonet.

Simple Screw-On Installation

Installation is a matter of threading the ring onto the 37mm lens threads and then screwing the 52mm filter into the ring. Cross-threading is the most common issue; turning the ring gently until it seats freely avoids damaged threads on either the lens or the filter.

Questions about this item

Should I choose a different step-up ring size for my 37mm lens?

This ring adapts a 37mm lens thread to accept 52mm filters; select it only if your filters are 52mm.

What does the 37mm to 52mm conversion mean when I attach it to my lens?

It lets you mount any 52mm threaded filter onto a lens that has a 37mm front thread, expanding your filter options.

Is the aluminium thread standardised so it fits every 37mm and 52mm accessory?

Yes, it uses the industry-standard filter thread pitch for both 37mm and 52mm sizes, ensuring broad compatibility.
