Fusnid Adapter - M42 Lens to Canon EF EOS v.III Camera Mount (With Focus Confirmation Chip)

This adapter lets you mount M42 thread-mount lenses onto the EF/EF-S mount of Canon EOS cameras.

What sets this adapter apart is its built-in chip, which lets the camera confirm when it's properly focused on the subject - effectively eliminating focusing errors.

Just like shooting with modern lenses, you can choose your focus point in the viewfinder settings while using a manual lens. The camera will alert you with the familiar beep and light indicator in the viewfinder once focus is achieved. Thanks to this chip, shots taken with manual lenses come out sharp, and shooting feels far more comfortable.

Why are "chipped" M42 to Canon EF EOS adapters so popular?

You can find a huge selection of affordable lenses across the post-Soviet space.

Unlike modern autofocus lenses, M42 lenses are significantly cheaper, and the price-to-quality ratio often makes them very appealing to beginner photography enthusiasts.

Using vintage all-metal lenses isn't just a nostalgic, fun experience - it's also a great way to try out a new aperture speed or focal length for the first time, all on a modern camera body.
