Lens Adapter Pixco OLYMPUS 4/3 to T2 mount SB2103

The Pixco OLYMPUS 4/3 to T2 mount SB2103 is a mechanical lens adapter designed to attach Olympus Four Thirds (4/3) lenses to devices with a T2 (M42x0.75) male threaded mount. This adapter provides a secure physical connection without any electronic contacts, preserving manual aperture and focus control of the attached lens. It is intended for photographers and hobbyists who need a reliable, low-profile interface for adapting vintage or modern 4/3 glass to astro rigs, macro bellows, microscope cameras and other photographic or imaging equipment that accepts a T2 thread.

Advantages

The adapter offers a durable metal construction and precise fit to ensure stable mounting and repeatable alignment. Because it is entirely mechanical and lacks electronic communication, it is lightweight and simple to use while retaining full manual control of the lens aperture and focus. The slim profile minimises extension between lens and mount, making it suitable for close-focus and macro setups. Compatibility with the common T2 thread standard increases versatility with a wide range of accessories.

Suitable for

• Attaching Olympus Four Thirds lenses to T2-equipped cameras and imaging devices
• Macro photography with bellows, extension tubes or reversed lens setups
• Astrophotography where T2-threaded adapters and focal reducers are used
• Experimental and laboratory imaging using microscope cameras or custom rigs

Key specifications

• Mount type (lens side): Olympus Four Thirds (4/3)
• Mount type (device side): T2 (M42x0.75) male thread
• Construction: mechanical, no electronic contacts
• Material: metal alloy with machined finish
• Profile: low-profile / slim design for minimal flange focal distance increase
• Color: typically black anodised

How to use

Mount the Olympus 4/3 lens onto the adapter by aligning the lens mount bayonet and twisting until it locks in place. Then screw the T2 male thread into the receiving T2 female thread on your camera, telescope, bellows or accessory until secure. Because the adapter provides no electronic connection, set aperture and focus manually on the lens before or after mounting. Verify mechanical fit and secure seating before operating the equipment to avoid cross-threading or damage.

Usage recommendations

Use the adapter on stable mounts or tripods when doing macro or astrophotography to avoid strain on the mount. Keep the contact surfaces clean and free of dust; when not in use, store the adapter in a padded case or box. For precise focusing or infinity focus verification, perform test shots and adjust backfocus with extension tubes or spacers if required by your setup.
