Samigon Adapter Tube F/Sony 45-52mm

The Samigon Adapter Tube F/Sony 45-52mm (ASM350) is a practical lens accessory designed to adapt a 45mm front thread to accept 52mm accessories. This type of adapter is especially useful when you want to use more common 52mm filters or attachments on a compatible Sony lens or optical accessory with a 45mm thread. By expanding the usable front thread size, it can help photographers and videographers get more value from existing filter kits without needing to purchase duplicate accessories in multiple sizes.

Compatible With

• Compatible Sony lenses or lens accessories with a 45mm front thread that need to accept 52mm screw-in accessories

Purpose and Function

An adapter tube like the ASM350 serves as a thread conversion solution. In practical use, it lets you attach 52mm filters or accessories to an optical component that originally supports 45mm threading. This can be useful for UV filters, protection filters, specialty effects filters, and other front-mounted 52mm accessories, depending on the physical clearance and design of the lens or accessory being used.

Key Benefits

One of the main advantages of a 45mm-to-52mm adapter is system flexibility. Since 52mm is a more common accessory size than 45mm, this adapter can reduce the need to maintain separate filter collections for different lenses. It can also make it easier to share accessories across multiple lenses, helping streamline your kit while improving convenience in the field.

Design and Handling

The compact, screw-in design keeps operation simple. It attaches directly to the front thread of a compatible lens or accessory and provides a 52mm front thread for added accessories. Because it is small and lightweight, it is easy to keep in a camera bag, accessory pouch, or filter wallet. This makes it a convenient solution for travel, everyday shooting, and general photographic use.

Typical Use Cases

Photographers may use this adapter to mount a 52mm UV filter for front-element protection, a circular polarizing filter for reducing reflections, or a creative effects filter for artistic results. It can also be useful when standardizing accessories across a mixed kit. If you already own 52mm filters, the ASM350 may help extend their usability to compatible Sony gear with a 45mm front thread.

How It Compares

Compared with buying separate 45mm filters for each purpose, an adapter tube can be a more cost-effective option if you already have 52mm accessories on hand. It also offers more flexibility than committing to a single dedicated filter size. As with any thread adapter, users should confirm physical compatibility and be mindful that stacking multiple accessories may increase the chance of vignetting on some lenses, especially at wider focal lengths.

Usage Tips

Before installation, make sure both thread surfaces are clean and free from grit. Start threading gently to avoid cross-threading, and do not overtighten. If you plan to use thicker filters or stack more than one accessory, check corners of the frame for potential vignetting. For best results, pair the adapter with slim-profile 52mm filters when working on wider-angle optics.

Recommended Accessories

Popular companion items include 52mm UV filters for protection, 52mm circular polarizers for outdoor photography, 52mm neutral density filters for long exposures and video, slim filter cases for storage, and a lens cleaning cloth or blower to keep threads and glass surfaces clean.

Build and Value

Samigon accessories are often chosen by photographers looking for straightforward, budget-conscious tools that solve common system compatibility issues. The ASM350 follows that same idea by delivering a simple mechanical solution that can expand accessory compatibility without adding much weight or complexity to your setup.
