Oh man, congrats on the R6!! It's such an amazing camera. I totally get the dilemma because those L-series lenses are highkey expensive to replace with RF glass. I was in the same boat recently! I really wanted the official control ring version but it's like $200, which is honestly wild for a metal tube, right?? So basically, I tried the Viltrox EF-EOS R Mount Adapter which is only around $50-$60. For the price, it’s actually fantastic! The AF speed felt basically identical to me. But yeah, if you're worried about weather sealing, the basic Canon Mount Adapter EF-EOS R is probably a safer bet and you can find them used for maybe $80 online. Tbh, unless you REALLY need that extra ring, I’d save the cash. The Viltrox worked great for me... maybe just be careful in heavy rain?? Hope that helps! gl!

Quick question - which specific L-series glass are you planning to use most?? Honestly, if you're using heavy lenses like the Canon EF 70-200mm f/2.8L IS III USM, you should probably stick to the official Canon stuff mentioned earlier just for the weather sealing. Before I give full advice, I'm curious if you're often out in the elements or just doing studio stuff... Basically, the official Canon Mount Adapter EF-EOS R has a proper rubber gasket that those budget versions highkey lack. I've used some off-brand ones and while the AF speed is usually identical since it's just a pass-through, the build quality can be hit or miss. I mean, I actually felt a tiny bit of "wiggle" with a cheaper mount once and it stressed me out so much!! If you want a fantastic alternative, look at the Meike MK-EFTR-B VN Drop-in Filter Mount Adapter. It’s reallyyy cool cuz you get a variable ND filter built right in. But seriously, for pure safety, the official Canon Control Ring Mount Adapter EF-EOS R is the way to go for L-series glass cuz those tolerances are perfect. I'm just a bit paranoid about cheaper metals wearing down ur camera mount over time, idk... anyway, gl!! 👍

just saw this and honestly it makes me kinda sad because it reminds me of when my cousin tried to go full diy on his old camera setup. he was convinced he could just machine his own adapter plate in his garage to save money.

• he spent like three weeks in the shop trying to get the flange distance exactly right
• the first time he mounted his glass the whole thing just wobbled like crazy
• he actually ended up stripping the screws on his mount because the metal was too soft it was just such a mess to watch him struggle with it while his expensive gear sat on a shelf gathering dust. really sucked seeing him miss out on a whole season of shooting because he wanted to do it himself instead of just getting back to taking photos. wish i could say it worked out better but it was a total disaster tbh.

Bump - same question here

man the r6 is such a fantastic choice for legacy glass! honestly that 12-pin rf communication protocol is amazing for keeping those older ef lenses snappy. i've been looking at the data on this. the throughput is wild. to really figure out if the premium version is a must for you tho, are you shooting mostly high-speed action where you need every bit of af tracking priority? also, are you planning on using any of the really heavy glass like those massive 300mm or 400mm primes? it matters. those mount tolerances and the rubber gaskets are way more critical if you are out in the elements for hours at a time!

just saw this thread popped up again. honestly been super satisfied with my setup lately without spending canon prices. ive been running the FotodioX Pro Lens Mount Adapter EF to RF on my r6 for a while now and no complaints so far, it just works. but before you pull the trigger on a budget option, are you using any third-party glass like older sigma art or tamron sp lenses? compatibility can sometimes get weird with non-canon glass on some cheaper adapters compared to how they handle the official l-series stuff. i've seen some weird af pulsing with older third-party chips. if youre looking to save some cash, the K&F Concept EF-EOS R Mount Adapter is also a solid choice for under fifty bucks. it fits tight and the pins communicate fine. just gotta make sure your specific lenses play nice with the software side of things first...

Same boat, watching this

honestly i spent forever researching this because i didnt want my expensive lenses falling off lol. basically there are a few other brands like Commlite CM-EF-EOS R and the Meike MK-EFTR-A Auto Focus Mount Adapter that seem to be pretty popular alternatives too. from what i’ve seen in market comparisons, most of these third-party ones use the same basic pin layout so the AF speed stays basically the same as native. but yeah, some users mention that the tolerances on the cheaper ones can be a bit hit or miss... like sometimes the lens might wiggle a tiny bit compared to the official ones? i guess ur paying the premium price just for that peace of mind and the perfect fit. has anyone here noticed if the JJC EF-EOS R Mount Adapter is any better for that? i'm trying to figure out if it's actually worth the risk or if i should just save up for the name brand stuff. anyway, congrats on the R6, it looks like such a cool camera!
