Wide-Angle Converter for Sony FE Lenses

The Vivitar 40.5 mm .43x wide-angle converter attaches to the filter threads of Sony FE 400 mm f/2.8 GM, 600 mm f/2.8 GB and EPZ 16-50 mm OSS lenses. It multiplies the focal length by .43, doubling the angle of view for expansive scenic, architectural and group compositions. All-glass multicoated optics are housed in a titanium barrel for durability.

Suited for Wide Scenes, Not for Telephoto Reach

Photographers who need a broader field of view without changing position will benefit from the converter and its included macro attachment for close-up work. It is not intended for shooters who require the original telephoto reach of the host lens or who need autofocus performance unaffected by additional glass.

Thread-Mount Accessory with Macro Option

The converter mounts directly to 58 mm filter threads; a stepping ring adapts it to other thread sizes such as the 40.5 mm front of the 16-50 mm OSS. No power or electronic coupling is required, leaving the camera’s native metering and stabilisation active while the macro attachment enables detailed near-subject capture.

Questions about this item

What filter-thread size must my Sony lens have to attach this 40.5 mm wide-angle converter?

The converter mounts on a 58 mm thread; use a 40.5 mm-to-58 mm stepping ring for the 16-50 mm OSS or other 40.5 mm threaded lenses.

Will the .43× converter work with my Sony FE 400 mm f/2.8 GM or 600 mm f/2.8 GB without vignetting?

The converter is designed for 58 mm threads common on wide-to-normal zooms; super-telephoto lenses like the 400 mm and 600 mm GM use much larger threads, so direct attachment is not possible.

How can I verify the .43× wide-angle effect and macro function are working after fitting the converter?

Compare the field of view at the same distance — the scene should appear roughly twice as wide — then engage the macro attachment and confirm sharp focus at very close range.
