Glad the video could help! I was in the same boat and was also happy to keep all of my EF glass 🤓

Glad the video could help! The backside of the adapter looks identical to the backside of an L-series lens. I'm not sure if third party adapters also include this or not, but it's a nice added touch from Canon!

Thanks! Glad it was helpful to you!

Glad I could provide, appreciate the kind words!

Appreciate it my guy! I think it's one of those features that has potential...if you remember to use it. Most of the time, I don't have one either though so I'm right there with ya!

Hi Sam! I'm happy my video could answer some questions for you! It all comes down to what suits your needs best, both cameras come loaded with specs and features, but the R is a very capable camera nonetheless!

Nice find on the adapter! Happy shooting, hope you're liking the R so far!

Thanks!

Appreciate you my guy!

Hey I appreciate it! Look forward to seeing you around 😎

Nice! The VND one sounds great!

@TeddyCavachon Does the usage of this adapter hinder any R6mkII functionalities like IBIS etc? Am asking about the Camera functions, not the lens functions.. Could you please let me know, Thank you.

@@suryatejak9815 I have not encountered any hindering of camera functions with either the Canon or Meike adapters.

That’s a really great question. I personally didn’t notice any effects as such, and my f/stops continued to perform as they did prior to the adapter.

Can’t say for sure on the third party adapters as I’ve never used one!

EF-S lenses cannot be boosted (at least on the wide part) as they do not have big enough image circle. Note also that you must have a crop body. If you shoot video and the body has extra crop for the video mode then boosting might be possible.

I don’t believe that’s to be expected. You lose auto-focus and stabilization of the lens?

@@CodyMajeres yes, it seems I see the shaky hand symbol. I do get focusing and if I switch to manual focus on lens it registers on camera.

So glad to hear it was helpful! Thankfully you can use those same lenses 👍🏼🙏🏼

You can’t use RF lenses, you’ll have to remove the adapter to use the RF lenses. Or, alternatively if you have only 1 EF lens you can just leave it attached to the lens. Kind of the same outcome but to answer your question, unfortunately not able to leave it on for RF lenses.

No! No loss of stop

It recognized my Tamron lens!

The adapter in this video is for camera bodies with RF mount for lenses, so it can attach to RF cameras and EF lenses. The 6D II is an EF camera, so depending on the Sigma lens you shouldn’t need an adapter. However, just to cover all bases, the adapter only works one way. You cannot flip it around and use it on EF camera for RF lenses. Hope this helps!

Oh no! I'm sorry you're running into this. Is it fair to assume that when you say "I have been using the lens adapter with no problems until the other night" that included auto-focus. So, during a lens change you randomly lost auto-focus capabilities with your adapter? Also, just to clarify, which adapter do you have?

I don't think this issue has to do with the adapter, but more so the AF function. I've had this same issue with my 50mm when I keep it on AF it's constantly searching for focus points (which you can hear and see it, as you mentioned). This really does drain the battery, I feel your pain! There's a few things I can think of that might help: 1. Try changing the AF mode to a different mode, such as 1-point or the square box that you can move around and select an area to focus. This prevents the camera from looking all over the scene for a focal point and narrows it to a much smaller area. This won't completely negate the issue though, it'll just give it a smaller space to search. 2. If your camera allows, set it to only pull focus when you half-press the shutter. This way, it's not searching until you NEED it to. This will negate the issue, however some shooting scenarios it may not be preferred if you need to act fast. 3. This may not be the most optimal, but putting the lens cap back on between shots will stop this from happening (and also further protect your lens!). But again, I realize this is not the best choice 😂 4. Keep it in MF until you want to shoot. This is another not-great option but it will fix the issue. And you will know very quickly when MF is on! I hope this helps, please let me know if you have any futher questions or concerns!

Go to single shot focus and not servo focus.

Correct, your 24mm will still be 24mm! As for which camera, they are both great. If looking at specs, the EOS R is going to just edge out the RP overall. More focus points, larger megapixel count, etc. If you do any video, the EOS R also is slightly better. However, if you’re priorities are not so much spec related and more size and comfort, the EOS RP is lighter and smaller while still keeping up with the EOS R for the most part! Hope that helps!

No quality decrease!

@@CodyMajeres correct there are no optics in the adapter only electrical contacts so there is no additional glass between your lenses and the sensor

The lens will not factor into the framerate of which a camera can shoot. Couple of things to try to get high frame rate: 1. Make sure you enable high frame rate video in settings. Some canon cameras have a setting that needs to be enabled. 2. Ensure your memory card can handle the load. V30 cards struggle and sometimes will not write because they can’t keep up with the transfer of video codec. 3. If you successfully capture footage and are reviewing the footage but it’s not slow, that’s because it won’t be slow until post-production. I hope this helps. Let me know if you still have issues with high frame rates! I can dive into it further if this doesn’t help 🙏🏼

From what I've seen, the camera will introduce that vignette, but it's not due to the adapter. Reason I say this, I use the EOS R at work with OUT an adapter, and at 15mm I notice vignetting. I use the older 16-35mm ii WITH the adapter at home and I don't notice the vignette as much as the 15mm.

I mean it all depends on what the camera being used is. If it's a DSLR, then I would recommend getting used EF lenses. If the new person is on a mirrorless, then I would tell them to see what they can get for used RF lenses, however I wouldn't tell someone who is new to drop a LOT of money. So I'd say get the base adapter and buy some used EF lenses to use with the adapter. RF lenses are new, so they are the most expensive. Because of that, the price of EF lenses will slowly decline and there should be a lot more available as seasoned photographers start transitioning to RF lenses. TL;DR A new person to Canon EF or RF should buy used EF glass and get the adapter if necessary. Won't need an adapter if it's a DSLR.

Definitely a huge perk! A little expensive, but if you’ve got the budget a good option.

No

That’s a valid question to have! My personal opinion would be to use the new camera for sure! The EFS lens will not bring down the performance of the camera. If anything, the camera will help the lens shine a little brighter! Of course, the RF lens will have better quality in technical terms. But without looking too deep into anything you won’t see much difference between the two. It’s more how the equipment is used than how new/old it is! You’ll be fine using the new camera with the EFS lens 👍🏼 Happy shooting!

Since you did not tell what your old camera is it is quite hard to answer. The adapter is not a relevant component on image quality.

Yes

How far away are we talking? Like infinity? I’ve noticed that happening with my R at 16mm a few times when trying to focus on clouds or things at infinity point. I think for my cases it had more to do with lack of light than anything. Not sure on your specific details if that could be the issue.

It doesn't have to be a Canon lens, but it has to be a Canon EF or Canon EF-S mount. For example, my Tamron lens that is made for a Canon EF mount can be used with my EOS R by using this adapter. So any Canon EF/EF-S lens, or any third-party lens that is made for Canon EF or EF-S mount will be able to be used with the adapter.

Yes, the adapter does not affect the ability to shoot video and does not remove any functions of auto focus. So yes, you can shoot video with eye-tracking auto-focus!

This is weird! Sorry you’re dealing with that. Can I ask what lenses you’re using? For example, EF 85mm f/1.2.

I'm using the 18-35 EF from Sigma and the 50 mm 1.4 from Sigma. Both of those doens't work. I do have the 10-18 ef from canon which is also behaving weird when using the adapter on the r5c@@CodyMajeres

Hmm...ok. I don't think I have a solution/answer for you but I do have some thoughts and some suggestions! I hope this helps: I'm thinking you maybe have a faulty adapter, as you also said in your comment. However, if you want to try a couple of things before sending it back, I would first check to make sure these lenses are compatible with the R5C. I'm not very familiar with that camera but I do know the R5 and the R5C have a list of lenses that just don't work with them. If you are confident the lenses are compatible, I would next ensure all firmwares are up to date. This includes lens firmwares and camera firmwares, they both have firmware. If the issue remains, I would double check your lenses and the adapter are properly attaching to the camera (listen for that satisfying "click" noise). If something isn't allowing either end to attach properly, don't force it. That could be the issue. Even though I'm sure you've read this a thousand times, I would also note that Canon isn't the most receptive of 3rd Party lenses, however since you state this happens with a Canon lens as well it does seem to be more than just that. I'll leave you with this: It sounds to me like it could just be a faulty device, and I hope that's the case! Based on what you described happens, it sounds like their might be a lack of communication between the lens and the camera that could be being caused by the adapter. But I will note that EF lenses are older and were made for different systems than what we have with these new R series cameras. It's also worth considering that your camera is just too much for these EF lenses and they are just not able to communicate with each other properly (which is why I suggest checking firmwares for sure). I hope this helps at least a little bit and am hopeful that it's just a defect (and that you get a new one soon so you can use your new camera!)

It can stay mounted! There's a small lock/unlock button on the adapter to unlock lenses and change lenses while keeping the adapter on the body.

@@CodyMajeres thanks! I was hoping there was a way to leave it attached to the body.

I can confirm EF-S lens work!

@Cody Majeres Outstanding thanks

It works but if you have a FF body it goes into a crop mode. On some bodies you may disable it but you get huge vignetting. On for example RP you cannot disable it - also you cannot use any aspect ratio but 3:2

I don't personally own that adapter, so I can't get as detailed. However, I know Viltrox is used by many as a third party adapter and seems to get the job done just fine. Sorry I can't be more help for your question, but I don't want to talk about a product I've never touched!

Are you able to describe the issues you’re running into? Based on my knowledge of that lens, it’s compatible with the mount.

It does not

What wasn't explained in the video but the adapter makes up for the different distance between the lens mount flange and the sensor. This distance is less in a mirrorless camera than it is in a dslr. That's because you don't have the distance taken up by the mirror box. Hence why mirrorless cameras are smaller and lighter than dslr's.

Not at all! You can get really great results with even the less expensive gear. Learning the proper way to use the gear will always outweigh better specs!

@@CodyMajeres Awesome, thanks for the confirmation! I was going to start with the 50mm "Nifty fifty". I also want a good zoom lens for nature or something capable of taking a picture of the moon. I have lots of research to do lol.

@@QuiresPan 50mm is such a great lens, you can’t go wrong there! As for nature, you could look for something like 70-200. Or like a 24-105. You could look for f/4 to keep the cost down.

Are they Canon brand? I assume they are since you mentioned L glass, but if any are third party I’m not sure if they’ll have the same marking system. As for Canon, yes the red dot or white square should be on the lens near the mount flange. It’ll still be on the black part of the camera, the side if you will. I’m trying to explain it best I can with words, but if you search Google images for “Canon Lens Red Dot” the second result is from Digital Photography Review and shows a great photo of both the dot and the square. I hope this helps, sorry if I explained it poorly!

@@CodyMajeres The only red dot on my lens is the one that's an index mark and it's on the side of the lens and not on the flange which is what your video seemed to show (bit that it was all that clear to begin with - way out of focus/blurry and poorly lit). All my lenses are Canon.

The index mark is the red dot you’re looking for

On the lens it’s on the side. On the adapter it’s on the flange.

@@CodyMajeres To clarify - are you talking about the lens index red dot you match up to the red dot on the body for mounting? Your description isn't at all clear.

No, one side is designed to be connected to an RF mount and the other side is designed to receive an EF mount. So if you flipped it, it would not work as then you would be putting a surface designed to receive a lens against another surface designed to receive a lens and vice versa. There would be no way for it to attach.

You cannot adapt mirrorless lenses to DSLRs as the adapter would have to have negative thickness. RF has flange distance 20 mm and EF 44 mm. An RF lens must be mounted 20 mm from the sensor and a DSLR has a mirror there. The only solution would be some adapter with optical elements and this would change the characteristics (the focal length) significantly or alternatively allow only macro shooting.

Short answer, no. The adapter in this video is for EF lenses and RF camera bodies, meaning the camera body has to have an RF mount. The T6i has an EF mount. To my knowledge they don’t make an adapter for an EF mount to accept RF lenses.

EF to RF will work for the R10

@@CodyMajeres thank you,I think ef to r is only for fullframe, the R10 will be available next week, it's my second camera after the 700d, so I'm a bit new to adapters😁

The EF-RF adapter is to attach EF lens mounts to RF body mounts. The R10 has an RF mount so that is the adapter you want. It won't matter if the lens or camera is crop sensor or full-frame!

@CodyMajeres thank you for the explanation,i get confused because it new to me and the shop tell me to buy ef to m🙏but now i know and will buy ef to rf

I do not unfortunately, I haven’t used any of those cameras personally!

I just picked up an R7 yesterday and I can (sadly) tell you that no matter what brand of adaptor you buy, you most likely wont be able to use any 3rd party lenses. Just some food for thought.

Thats how I ended up on this video, I'm still looking for workarounds for my Tamron 17-50mm 2.8

@@DistractionPhoto If the third party lens is an Canon EF or EF-S mount, yes you can. I use Tamron lenses on my Canon EOS R with the adapter to this day! Edit: Seems that the R7’s are having issues (and potentially others?). Sorry that’s happening, super annoying! Hopefully Canon can come out with a fix for this soon!

@@DistractionPhoto After looking this up, it seems to be an issue on Canon’s part with the R7. The adapter is designed to work with all models, however I’m seeing that the R7’s are having issues with the adapter.

So I actually ran into this too, I personally haven’t found an adapter that lets you use canon lenses on Sony cameras with full functionality. It’ll let you see the image, but I wasn’t able to change aperture or use autofocus. I think I read somewhere that there ARE adapters that let you do this, they are just very expensive. The main issue is canon lenses aren’t made to communicate with Sony cameras and most canon-Sony adapters don’t solve that.

@@CodyMajeresTHANK YOU!! Okay good I thought I was crazy haha, had a Sony for years and love my canon glass. Was never an issue as I was mainly doing video but now that I’m doing more photography not having autofocus has been such a bummer. Think I’m gonna get a Canon R5 I’m not meant for Sony lol

Canon does have some great glass! The R5/R5C is a beast of a camera. You will love it if you are already invested in canon glass!

Does not increase focal length

I would say that’s entirely up to you and what you shoot and what you want to get out of your next lens! I personally don’t have any use for a fisheye but you might!

Oh shoot. Well I hope this helped clear up any questions you had! If not let me know

That would be crop factor and the distance is so minimal that it’s not noticeable. Unless you are pixel peeping maybe 🙂 not enough to claim a crop is introduced though.

Is your camera the EOS R? If so, the EOS M adapter is not the right adapter and that could be the issue. You will need the EOS EF/RF adapter.

@@CodyMajeres It's an EOS M 6 II. you're probably right. Thank you. I'll look into it.

If you have the EOS M then I believe you have the right adapter. So that makes me think the adapter may be faulty? I don’t think a rattling sound is normal!! 😅 I’d maybe try to return the adapter and get a new one to replace it? That’d be my first action! Good luck!

@@CodyMajeres Thank you.

I don't believe so

@@CodyMajeres Thanks for responding - there are some who say you can remove the plastic ring - but could damage the lens or mirror. Thanks for the great video.

Of course! I'm sure there are ways to make it work, but none that I would feel comfortable recommending to others as I have not done them myself.

One more note - you are an EXTREMELY talented KZfaqr - I am recommending you keep finding great ideas that excite you and please continue to post more content. You will get subscribers ... I just wanted to send a positive and encouraging note. Just subbed and gave a thumbs-up.

Thank you! I really appreciate that. July into August was real busy for me, but I'm hoping to have a few videos coming real soon with a lot of ideas for some others.

You’re not alone!

This adapter only works for EF lenses on RF bodies.

are you aware of any EF body adapters that use RF? @@CodyMajeres

@@bakdogg I looked it up after your initial comment and I couldn’t find any unfortunately.

thanks for the effort 👍👍@@CodyMajeres

@@bakdogg Not possible. You can adapt only when the lens has a longer flange distance than the body. EF has 20 mm and EF 44 mm.

No noise!

It's a cine lens

No, the M50 is an M mount. To my knowledge they do not have an RF to M adapter. There is EF to M adapter and EF to RF adapter, but none that would allow you to put RF lens on M mount camera. Sorry!
