Are there any recommended lens adapters for using EF glass on L-mount?

Question

I just grabbed a Lumix S5II for a wedding gig this Saturday and totally forgot I need an adapter for my Canon glass. Everyone keeps mentioning the Sigma MC-21 but then I read the continuous autofocus is basically dead for video which is what I mostly do. Is the Fotodiox Pro any better or am I just gonna be stuck with manual focus for the whole shoot?

Saw this just now and wow... doing a wedding this Saturday with a brand new body and adapted glass is living on the edge lol. In my experience, even the decent adapters like the Viltrox EF-L Pro Lens Mount Adapter can be a bit jittery for video if the lens is older. Since youre looking at budget and practicality:Honestly, just rent native glass for the weekend. Check LensRentals or a local shop. Its like 50 bucks and saves you the headache of missed focus during the vows.If you really want an adapter, look for the Metabones Canon EF to L-Mount T Smart Adapter. Its pricier but I've tried many and it feels the most solid.Always check the firmware compatibility lists on the manufacturer sites before buying. Some lenses just wont play nice no matter what. If the budget is tight, skip the adapter and grab a Panasonic Lumix S 50mm f/1.8 L-Mount Lens used. Native AF is just a different world on the S5II.

Doing a wedding with a brand new setup you havent tested is a bold move lol. Honestly, I'd be real cautious with the Sigma MC-21 Mount Converter EF-L for video. Even though the S5II has phase detect, that adapter still acts wonky sometimes in continuous mode depending on the lens. I would suggest avoiding the Fotodiox Pro Fusion Adapter EF to L-Mount for high-stakes stuff like this because the firmware can be glitchy and might drop connection. Tbh, you might want to consider just renting a native lens like the Panasonic Lumix S 24-105mm f/4 Macro OIS for the weekend. Adapted glass is fine for b-roll, but for the ceremony? I wouldnt trust it to track a walking bride perfectly. If you're stuck with EF, the Sigma is basically the standard, but maybe prepare to pull focus manually... just in case.
