Holds the lens tight. Gets the job done. Definitely more appropriately priced than some of the other adapters, although I can't speak to the quality of the others in comparison. Just can't imagine there's much more to the hardware. Only issue I've run into is a distinct softness in focus around the edges of the frame when at an f4-f1.8 on my Canon ENG lens (YJ19X9B4) on the JVC LS-300. It's pretty negligible at a 4, but definitely more noticeable wide open at a 1.8. I don't think that's an issue with the adapter, though. I think it's more of an imaging and depth of field problem since the b4 lens is designed for a 2/3" sensor. Not a deal-breaker for the B4-MFT approach since you gain so much more in lens length and functionality without having to break the bank (got two used b4 Canon lenses for $1k - both in great condition). Just something to be aware of.

Where versatility meets affordability, the Mount Adapter for B4 (2/3") Lens to Micro Four Thirds Mount Mirrorless Camera stands out as a high-quality, durable, and compact solution for photographers. This mechanical adapter seamlessly connects a B4 2/3" lens to a Micro Four Thirds (MFT) camera body, expanding your lens options without the need for new purchases.
While it doesn't include corrective optics, the adapter may result in vignetting depending on the lens used. However, its ability to breathe new life into your prime lenses with your latest camera makes it an invaluable tool for both professional and amateur photographers.
Crafted to pristine award standards, this Fotodiox 'Pro' Series adapter ensures a perfect fit between your camera and lens. Its unique design not only guarantees a secure connection with no "play" thanks to the leaf springs emulating the camera body, but also enhances the professional appearance of your equipment.
Please note that automatic diaphragm, auto-focusing, and other electronic functions may not operate correctly with this adapter. As such, "stop-down mode" will need to be used for metering, as the lens does not have the ability to have its aperture controlled by the camera body. However, infinity focusing is guaranteed, making this adapter a versatile and cost-effective addition to your photography gear.
