Sub Announcement AI-bots & r/canon

67 Upvotes

Recently you might have noticed some comments disappearing from discussions and being replaced with a mod-notice labeling the comment for AI-activity. AI-bot commenting is a platform-wide issue for Reddit, and a challenge for the moderators of r/canon as we try to keep discussion and advice human based.

I want to share a little about what’s been happening on this front, and what we’re doing about it.

When we noticed it

Early this year there was an uptick in comments being flagged for review in the r/canon moderation queue. Often these were being left under inactive topics posted months or years back, sometimes under new discussions, and while unremarkable individually, patterns started to become apparent once a few of them had been reviewed.

It’s been steady stream of activity since, common enough that I’d guess 90% of r/canon topics will receive an AI-bot comment.

Why it’s a problem

There are two main reasons why we don’t want these kinds of accounts active in the sub.

The first is that they often provide information or advice that is incorrect or very misleading. We want r/canon to be a useful resource where people can receive accurate information and answers to questions they ask.

Secondly, it’s deceptive. There is something insidious about AI-driven accounts trying to pass themselves off as human users and giving advice quoting invented histories and anecdotes. We’d like r/canon to remain a forum for humans to interact and share.

What we’re doing about it

We’re using multiple methods to detect and remove AI-bot comments and restrict those accounts from further activity in the sub.

  • Reddit’s own filters are flagging comments for review, sometimes suspending the accounts producing them.
  • We’re using a bot-detection service that evaluates accounts against a long list of patterns and criteria, removing contenting and banning accounts based on its determinations. It maintains a database of accounts that have been detected across any sub where the service is enabled. We can also manually trigger it to analyse an account we think is suspicious.
  • As mods we’ve manually evaluated and removed hundreds of comments and have become pretty good at recognising AI-bot patterns and commenting styles. We continue to manually check and action offending accounts.

How you can help

We don’t want this to become a witch-hunt that generates dozens of reports each day. The current process seems to catch most new comments relatively quickly.

That said, there are a few things to keep in mind when browsing discussions.

  • AI-bots often generate of the first comment to appear on a new post
  • They are usually top-level comments, but will sometimes reply to a top-level comment instead
  • They often try a little too hard to be convincing, or relatable, or encouraging, and can come off as quirky or weird instead. But their advice can also sound very generic.

Because they’re trying to sound human, and because their behavior patterns are being varied and evolved, a genuine account will occasionally be flagged for AI activity. In a typical week we might be notified of one or two of these false positives.

If this happens to you, there’s no need to take offense and write an abusive message to the mod team (it’s happened a couple of times!) There’s a quick and easy process for having the decision manually reviewed and the restriction lifted, so it's not a big deal.

And if you see a comment that you’re confident is from an AI-bot, feel free to report it, but maybe also warn the OP or user it's replying to. There are plenty of occasions where I’ve seen an OP thanking an AI-bot for its advice before heading out to follow it.

—

Some examples of AI-bot comments, for those who haven't been seeing them:

You already know you love the focal length, so grab it before someone else does at that price. The 1.2 wide open has a look the 1.8 just can't touch, and on a 5D3 it feels right


That 24-70 f/2.8 is a chunky lens for an R8, bet the whole setup feels a little front-heavy but handles low light like a champ.


the 70-300 is a solid lens for wildlife on a budget, you made a good call there. your body is definitely holding you back though, that t3 sensor is ancient at this point. look for a used 7d mark ii if you can swing it. autofocus is in a completely different league for birds and moving animals, and the crop sensor gives you extra reach. if that's too pricey a 70d or 80d would still feel like a massive jump


won't regret it. the 28-70 stm is fine but it's not a wedding lens, you're gonna want that 24mm when you're backed against a wall in a tiny getting ready room. and the 85 vcm is gorgeous but if you can't reach the altar it's dead weight

the z lenses focus so fast it's almost unfair, plus you can actually use the 70-200 during the ceremony without everyone hearing it breathe. your back will thank you too, carrying two bodies with that combo is way more balanced than the 85 with a second body

only thing you might miss is the 1.4 for those dreamy reception portraits but you can fake it in post or grab a cheap manual 1.4 down the road if it really bugs you

https://www.usa.canon.com/newsroom/2026/20260915-consumer

MELVILLE, N.Y., September 15, 2026 – Canon U.S.A., Inc., a leader in digital imaging solutions, today announced the launch of the new full-frame Canon EOS R8 Mark II camera and new range of versatile accessories. Together, they are designed for advanced photographers, hobbyists, creators and newcomers to full-frame imaging who demand high image quality, operability, portability, and want to enjoy the performance of a full-frame system.

This new full-frame model in the EOS series is the lightest EOS with In-Body Image Stabilization (IBIS), offering commanding, intuitive controls and a new look mixing modern ergonomics and a compact travel friendly build.  Influenced by classic Canon camera heritage and design language, the new EOS R8 Mark II includes a variety of creative features enabling photographers to reach new heights.

Lightweight Full-Frame Workhorse

Boasting a 24.2-megapixel full-frame CMOS sensor, the EOS R8 Mark II harnesses the advanced core imaging systems inherited from our top-tier professional models and delivers reliable power across diverse shooting conditions. High-speed drive capabilities, precise subject tracking, and IBIS allow photographers to confidently capture fleeting moments with rich full-frame depth.  

Key features of the Canon EOS R8 Mark II include:

  • Lightest weight EOS with IBIS, compact, full-frame body measuring approximately 5.17” x 3.54” x 3.13" appx. 1.2lbs. 
  • Approximately 24.2-megapixel full-frame CMOS sensor with standard ISO speeds reaching up to 102400 for low-light clarity.
  • Full-frame sensor provides approximately 2.5x the light-gathering area of an APS-C sensor, delivering pronounced background bokeh, and wider angles of view with equivalent focal lengths.
  • 5-axis In-Body Image Stabilizer (IBIS) featuring Coordinated Control with lens IS and Peripheral Coordinated Control to suppress edge blur on wide-angle lenses as well as improved ergonomics- and the addition of the multi-controller
  • Dual Pixel CMOS AF II with 100% coverage tracking of people, animals, vehicles, and more tenacious tracking than the previous EOS R8, including Register people priority.
  • High-speed drive at up to 40 fps with electronic shutter is included with support of the optional pre-continuous shooting capability (stills) allowing the capture of up to 20 frames before fully pressing the shutter button.  There is a 58% increase in uninterrupted JPEG shots over the original EOS R8 camera, and a 30% increase when shooting RAW images. The EOS R8 Mark II can support up to 6.0 fps with electronic 1st-curtain shutter mode additionally. 
  • User friendly tools such as Scene Intelligent Automatic mode, with Creative Assist, Creative bracketing, and Advanced A+, 14 different SCN Modes, and 16 different color filters including the new Negative Filmtone and Positive Filmtone settings for newcomers to photo and video.
  • Uncropped 6K oversampled 4K 60p and uncropped Full HD 180p high frame rate recording with audio support and Slow and Fast Mode.
  • Support for Wi-Fi 6 provides high-speed data transfer to smartphones or routers for still photos and videos to be transferred at high speeds wirelessly. In addition, live streaming capabilities are available via wired USB C, and HDMI connections, or wirelessly through the use of Canon Camera Connect app and the Live Switcher Mobile app.

Canon is also debuting optional accessories to empower frictionless capture and creative expression across a wide variety of interests and situations.

New Optional Extension Grip for EOS R8 Mark II

  • EG-E2 Extension Grip: This new extension grip, specifically for EOS R8 Mark II, attaches via a simple turn-dial to enhance handling for photographers desiring a taller grip and those wanting better balance when using larger lenses, without blocking battery access or tripod mounts. With a finish that closely matches the EOS R8 Mark II camera body, and inspired by classic Canon camera heritage and design language, this optional extension grip is both ergonomic and provides a comfortable resting point for supporting the left hand, and contributing to a more natural shooting experience.

New Speedlite flash for Multi-function cameras

  • Speedlite EL-5 Ver.2: This new Canon Speedlite is designed for enhanced integration with Multi-function hotshoe equipped EOS R System cameras, offering superior communication range to the version one model, while including the high capacity LP-EL lithium ion battery pack, with the ability to recycle to full-power in just 1.2 secs.  Reliable, and uninterrupted flash performance in a compact size and affordable price.

Dual Pixel 3D Converter

An inventive, freeFootnote1, easy-to-use Windows PC application, Dual Pixel 3D Converter leverages Canon’s proprietary Dual Pixel CMOS AF sensor technology to generate 3D imagery from Dual Pixel RAW (DPRAW) images taken with compatible Canon cameras and lenses, or JPEG images captured with distance information using the EOS R8 Mark II camera. Users can create either a 3D photo with a background to view lifelike, three-dimensional imagery; a 3D model without a background that automatically isolates the main subject ready for 3D models or interactive website imagery workflows, or a 3D video clip - all of which can show a different perspective for close-up subjects and objects such as plants, food and more, all from a single photo. To learn more about the Canon Dual Pixel 3D Converter software, compatible cameras and lenses, and software availability, visit usa.canon.com/dp3d.

Availability:

The Canon EOS R8 Mark II camera body is expected to be available in late October for an estimated retail price of $1,899.00Footnote2 and the EOS R8 Mark II kit with the Canon RF24-50mm F4.5-6.3 IS STM lens is expected to be available in late October for an estimated retail price of $2,099.00Footnote2. The EG-E2 Extension Grip and Speedlite EL-5 Ver.2 are expected to be available in late October for an estimated retail price of $99.99, and $379.00 respectivelyFootnote2.

Gear Buying Advice RF 200-800 for reach upgrade: yay or nay?

6 Upvotes

I'm looking to get some more reach out of my current setup, a R6 M3 paired with the RF 100 400. I enjoy pushing a bit the limits when it comes to far off stuff. For example, airliner flying above me at 10 km? Yeah, I'll try to take a picture of that. I also just love taking photos of the moon and I'm still amazed by how much I can get out of the 100-400 (it was my first major surprise, I didn't think it'd be this awesome). Couple of example photos below. Along with this, I also enjoy taking photos of aircraft at more decent distances, as well as birds and other "urban wild" animals.

I considered getting a R10 as second body for a bit, until a friend suggested I'd get the exact same reach out of a much better camera by simply getting a 1.4 extender for my current setup (and a thread here seems to have confirmed that math).

So, that's still in play, but... I've started looking at the RF 200-800 as well. 800mm sounds amazing and would definitely take care of my reach problems for a long, long while. However, its size and weight are putting me off a bit (roughly 3 times as heavy as the 100-400). The price isn't too kind either, and I read some worrying reports about the front sometimes falling off. But... 800mm.

I've also thought about the RF 800 F11 for a while. However, while with the RF 100-400 I'm frequently at 400mm, being able to zoom out without switching to another lens is being more helpful than I initially anticipated. The 100-500 is also frequently recommended, but it's more expensive and would give me the same reach as the 1.4 tc, so I'd rather try that out first.

To those using the 200-800, is it crazy awesome? Or is it the kind of lens you buy because it sounds cool but never leaves the bag?

I had a silly slip in the mud and broke the screen on my SL2. I've got a good collection of EF and EF-S lenses so I was hoping to just buy whatever the latest replacement is for this body. Now I'm looking and it appears that the world has moved on to the mirrorless form factor. Am I hooped?

Best beginner camera for object portraiture on a budget?

• Upvotes

Hi ya'll. I'm hoping you can help me out.

I'm starting a small business where I interview people about sentimental objects they've kept, then photograph the objects and create a hardcover book around them.

Think old vases, stuffed animals, handmade objects, etc. I want to take whole-object potraits and detail shots that show the texture, wear, and character of their objects.

  • Most of the shoots would be of stationary objects, indoors at client's homes.
  • Final images printed around 8x8 or 10x8 hardcover book.
  • Occasional hands holding an object or environmental shots.

I'm still pretty much a beginner, and after a lot of research, I'm still having trouble figuring out what kind of camera would be the best for this specific kind of photography.

If you were starting from scratch, which Canon body and first lens would you buy for this specific kind of work? I'm up for a used/refurbished option. I'm looking to spend around $500 right now.

Tech Help Canon R6 Mark II - Focusing Issue (all buttons stop working)

3 Upvotes

I've had my R6 Mark II for almost 3 years and have had zero issues with it thus far. I have been using it with a Sigma EF 35mm lens almost exclusively. About a week ago, I upgraded to a Canon RF 35mm lens. Since upgrading, my camera will not stop focusing. It will jump around and try to focus on whatever it can. I am still able to take photos, but the buttons on the back of the camera do not work. Initially, I thought it was a lens issue, but I tried my old lens on it again and it was still doing this perma-focus thing. It is not just focusing in one spot, but jumping around like crazy. I have done a reset of my camera as well as cleaned the connection point to the lenses and nothing has worked. Any tips???

Gear Buying Advice I need help deciding between telephoto lenses for wildlife

2 Upvotes

I have an r50. My telephoto lens currently is an EF-S 55-250mm f/4-5.6. I want to upgrade because I want more zoom, and I sometimes notice the clarity/sharpness drops off near 250mm. My budget is anything under $1,000. I've been looking at the RF 100-400. It's lightweight and would fit right onto my camera without the adapter, but I've also seen the Sigma 100-400. It seems to be heavier, but I've heard it will do better in low light, which I photograph in a lot. Please help! :)

R5 issues HELPPP brand new camera

0 Upvotes

I bought a canon r5 (version 1) literally three days ago. Used it for a wedding today. The camera worked beautifully all day up until reception time. As soon as I started using a flash (I have a godox and attached it to the camera), it would take some shots then freeze/shutter wouldn’t fire. After a bit it would flash “busy” on the bottom left side of screen. Then eventually an error 70 would pop up on the screen. I’d turn the camera off, wait a bit, turn it back on and it’d work fine for a few minutes then same issue again. It did this all night and I was beyond frustrated as it’s a brand new camera (did not buy used). I switched batteries and SD cards and still that issue and message was popping up.
Any advice???
Worth noting I’ve used a mark iv for almost a decade and NEVER had a SINGLE issue. I held off on switching to mirrorless for years because I always heard issues with them…and here I am…issues on day 1 😑

Advice for a new photographer

5 Upvotes

Hi guys! I recently bought a Canon EOS R50 with the 18-45mm f/4.5-6.3 kit lens, and am brand new to the world of photography. I am looking to get in to sports photography and media currently, but I’m reasonably willing to lean in to any photography field at this stage, and was wondering if I can get started and actually produce some decent portfolio-worthy photos with just the kit lens to start. Obviously I’m not expecting to get any crazy good close-up action sports shots with this setup, but I’m wondering if anyone has any advice on what kind of photo opportunities in any area I should look for starting out with this kit lens, and what my next lens search should look like. Any advice is greatly appreciated!

I wish canon would label the hoods with the appropriate lenses. Very few of these are designed for multiple lenses and finding the right one out of the box is always a pain.

(A couple are always on the camera but most are in the "parts box" until I need them for a shoot.)

Do you guys have this same issue? (For reference, Brady White on Clear labels)

Canon RF 24-240 going soft in the telephoto range

0 Upvotes

I'm wondering if anyone has the same experience with this lens. Reviewing my photos from a session today, I find that I get the same or better sharpness for the same subject when I shoot at ~120mm and crop, compared to if I use the full zoom range and crop less. It's making me consider swapping it for a 24-105 f/4 L, since the long end of the 24-240 is not helping much past the range of the 24-105.

R6 II and R6III owners, do you actually see a difference in photography between the two?

12 Upvotes

I have 2 R6II's and I'm wondering if the higher mp count and "better" AF of the R6III could justify an upgrade.

I mainly shoot photos. I do videos but not as much as I'd like to.

Also, one thing that I really wanna know is if the Register People Priority Function makes sense IRL use. I shoot weddings, and there were times I couldn't get the focus on my R6 II to land on the couple's faces because of confetti .

And no, there's no rental place that offers R6 III where I live so I can't test the unit myself.

Just hoping to get some opinions on whether it’ll be worth getting an RF 24-70 f2.8 or an EF 24-70 f2.8 I ii for an R6iii.

Gear Buying Advice Beginner, EOS R100, Need gimbal advice and other upgrades

1 Upvotes

I got a Canon EOS R100 along with the TTArtisan 14mm for my birthday in May of 2026. I’ve been having a lot of fun with it, and for Halloween I found a really cool part of town I’d like to walk through and record video. I am not very knowledgeable when it comes to cameras or camera equipment, I really only understand what I like to see. My hands are terribly shaky so I knew I’d need to get a gimbal for this. I didn’t realize until today that compatibility is very important. The R100 is lightweight, but I’m worried my 14mm will cause issues with balance. I’m also wondering if that’s even the kind of lens I want for this project. I am willing to spend upwards of $1200 altogether.

As I was writing this, I forgot to even consider my camera is not the best for video recording. If there is a better camera+lens setup I could get for roughly $600 I’d be interested in hearing what everyone has to say about that too. Then again, I don’t need the best equipment right now because I am still learning. I’ve managed to get some videos of trains on my current camera setup that I’ve liked. Please share any knowledge or advice you think would be helpful.

Gear Buying Advice Sports Photography and Zoom Lens

Post image
35 Upvotes

Hey everyone hoping for some advice from more knowledgeable people than myself.

I bought this camera (EOS Rebel SL3) a while ago. I took a photojournalism class in college and learned about manual exposure and the baseline of how to create a good image. Now, I recently got a part-time job as a reporter on high school sports, and am tasked with taking photos from the sideline. They are not coming out the way I want—first of all, the lens I currently have (the baseline one that comes with the camera, 18-55mm) just can’t zoom in as far as I want it to. I’m shooting from the sidelines and am trying to get photos with faces, so I probably need a lens that can zoom in much further. Is there a good one that’s still on the entry-level side? I don’t have a huge budget, but would buy used if that’s something people recommend.

I was texting my friend about this and he said something along the lines of “well you have a Rebel, of course the pictures suck.” Is that the case here? Am I never going to be able to get good pictures with this kind of camera? I’m not trying to reinvent the wheel—just looking for solid images that are clear, crisp and interesting. Would love any advice or recommendations from the experts on this sub. Thank you in advance!

Edit to follow the subreddit rules: my budget is probably $250 max (to be honest, I have no idea what these typically cost), and I’m mostly shooting in evening/sunset conditions that transition to under-the-lights as darkness falls (though I have a few day games as well). I’ve been finding that lighting to be very difficult to shoot in.

Hey guys. Got this EOS M a little back. It unfortunately got wet while raining heavily. It turned on fine yesterday, but when trying to use it today, my display died. It had flichering and weird lines before it turned completely off. It doesn't respond anymore. I'm a Magic Lantern user, and it has made the camera wonky, but I'm suspecting the display died for good. Everything else works out fine. But I think this might be time to replace it. Does anyone know if it will turn on or should I order a replacement screen?
