Canon EOS-M users have been stuck with a lens ecosystem that's, well, limited. Enter the Dual Mount—a $89.99 collaboration between Filmatura and Alt Cine that cracks open Sony's E-Mount treasure chest. This CNC-machined stainless steel adapter isn't exactly plug-and-play territory. It's experimental, requires careful installation, and Canon probably isn't thrilled about it. But for photographers tired of Canon's mirrorless lens drought, this little piece of metal might just change everything. The question is whether it actually works.

When Canon decided to give their EOS-M mount the same enthusiasm they show for their mirrorless lineup, which is to say, barely any, the third-party manufacturers stepped in to fill the void. Enter the Dual Mount, a $89.99 collaboration between Filmatura and Alt Cine that promises to breathe new life into Canon's neglected system.
This CNC-machined stainless steel adapter lets EOS-M users mount E-Mount lenses and adapters.
Yes, you read that right, with this Sony's vast E-Mount ecosystem suddenly becomes accessible on your Canon's EOS M. The laser-engraved adapter represents what Canon probably should have done years ago.
But let's be clear about what this is. It's an experimental modification. Use at your own risk. Not all Sony-E lenses will play nice, and there's no guarantee everything will fit perfectly. The manufacturers maintain a compatibility spreadsheet where users can share their experiences, which is both helpful and slightly terrifying.
Installation looks simple, but here's where things get interesting. Those original screws? They're apparently made of something resembling compressed chalk. Mishandle them while disassembly and you'll strip them faster than you can say "warranty void." The instructions emphasize applying downward pressure, unscrewing in a cross pattern, and avoiding overtightening. Basically, treat those screws like they're made of dreams and disappointment.
The Dual Mount only works with Canon EOS-M cameras. That's it. Don't even think about trying it on other systems. It's engineered specifically for this one camera and its unique layout.
Customer support promises responses within 24 hours, worldwide shipping with tracking, and assistance with product questions or returns. They seem committed to helping users navigate this experimental territory.
For EOS-M users tired of Canon's limited lens selection, this adapter opens doors that Canon seemingly welded shut. At under $90, it's cheaper than crying into your camera bag while browsing Sony's lens catalog.
Sure, it's experimental, potentially finicky, and requires careful handling. But for Magic Lantern users stuck in Canon's EOS-M ecosystem, the Dual Mount is the lifeline they've been waiting for.
