Samigon Step-Up Ring 28-37 mm

The Samigon Step-Up Ring 28-37 mm is a practical adapter designed to let lenses with a 28mm front filter thread accept 37mm filters, caps, and other threaded accessories. It is an easy solution for photographers and content creators who want to standardize accessories across multiple lenses without buying the same filter in several sizes.

Compatible With

• Lenses with a 28mm front filter thread, for use with 37mm threaded filters and accessories

Key Function

A step-up ring increases the usable accessory thread size on the front of a lens. In this case, the ring converts a 28mm thread to 37mm, allowing you to mount larger 37mm UV filters, polarizers, ND filters, close-up filters, protective filters, and similar screw-in accessories on compatible lenses.

Benefits of a 28mm to 37mm Step-Up Ring

Using a step-up ring can help simplify your kit and reduce cost. Instead of purchasing multiple filters in different sizes, you can invest in one set of 37mm filters and use them on qualifying smaller-thread lenses. This is especially helpful for photographers using compact lenses, camcorders, or specialty optics with smaller front threads.

Construction and Handling

The Samigon Step-Up Ring is designed to be lightweight and unobtrusive, so it adds very little size or weight to your setup. Its threaded design enables a secure screw-on connection between the lens and accessory. Because it is small and easy to carry, it is a convenient addition to any camera bag or filter pouch.

Typical Use Cases

This accessory is useful when attaching a 37mm UV filter for lens protection, a circular polarizer for controlling reflections, or a neutral density filter for longer exposures or wider apertures in bright light. It can also be helpful for adapting lens caps or select hoods that match the new 37mm front size, provided the accessory design allows proper fit.

Usage Tips

Before installation, confirm that your lens has a 28mm front filter thread, usually marked on the lens barrel or lens cap. Thread the ring on gently to avoid cross-threading, then attach your 37mm accessory to the front of the adapter. As with any step-up solution, keep in mind that some original snap-on caps or dedicated hoods sized for the smaller thread may no longer fit once the ring is installed.

Who It Is For

The Samigon Step-Up Ring 28-37 mm is well suited for photographers, videographers, hobbyists, and anyone building a more efficient filter system. It is especially useful for users who want an affordable, straightforward accessory that expands compatibility between a smaller lens thread and a more common accessory size.
