Stopped dead in my tracks. Blown away by a tiny blinking red square. It’s the kind of thing that makes you want to hurl your expensive camera gear into the nearest bin, isn’t it?
I remember my first encounter with that infernal glowing rectangle on my Canon EOS 6D. I thought I’d broken it, that some expensive sensor damage had occurred. Panic stations. Hours spent online, reading forums filled with equally panicked folks.
So, how to get rid of red square on Canon camera? It’s usually not the catastrophic failure you fear. More often than not, it’s something ridiculously simple that Canon’s manual seems to have deliberately obscured.
That Blinking Red Square: What It Actually Means
Honestly, that little red square, often accompanied by a flashing symbol and sometimes an error code like ‘Err 05’ or ‘Err 70’, feels like a death knell for your photography session. It’s the camera’s way of throwing a tantrum. It’s saying, ‘Nope. Not playing today.’ You’ll see it when you try to take a shot, or sometimes even when you’re just trying to review photos.
It’s not a sophisticated diagnostic tool. It’s more like a toddler’s insistent ‘NO!’ It signals an internal hiccup, a communication breakdown between components, or a simple power-related issue. The panic is real, I get it. I once spent an entire afternoon in Yosemite, meticulously setting up landscape shots, only to be met with this blinking nemesis. My carefully composed shots of Half Dome? Gone. I felt like I’d wasted an entire day, not to mention the gas to get there. That was after I’d already spent around $180 testing a couple of generic ‘fix-it’ accessories that did absolutely nothing but drain my wallet.
The Usual Suspects: Simple Fixes First
Before you start mentally drafting your angry Amazon review for Canon, let’s try the absolute basics. Think of it like trying to fix your Wi-Fi by just unplugging and replugging the router. Sounds daft, but it often works.
Battery Check: This is number one. A low or failing battery is the culprit more times than you’d think. Remove the battery completely, wait a good 30 seconds – let it really ‘forget’ whatever it was doing – and then pop it back in firmly. Make sure it clicks into place. If you have a spare battery, try swapping it out. Seriously, I’ve seen my friend’s 5D Mark IV refuse to budge because the battery wasn’t seated properly. It looked like a major malfunction, but it was just loose. (See Also: How To Reset Zosi Camera System )
Memory Card Shenanigans: Your SD card can also be a troublemaker. Take it out. Give the contacts a gentle wipe with a clean, lint-free cloth – no spit, no industrial solvents. Insert it again. If you have multiple cards, try a different one. Sometimes, a card can get corrupted, and the camera freaks out. This isn’t your card’s fault, necessarily; it’s the camera’s reaction to what it perceives as an issue with the card’s data. Think of it like a librarian finding a book out of place and shutting down the whole library because they can’t find the Dewey Decimal number.
Lens Connection: The same logic applies to your lens. Detach it, look at the metal contacts on both the lens and the camera body. Are they clean? Are there any obvious dents or scratches? Reattach the lens, making sure it clicks securely into place. Sometimes, a slightly misaligned lens can cause communication errors. I’ve even had to gently wiggle a lens connection to get it to seat properly and clear an error.
Firmware Follies: While less common for a simple red square, outdated firmware can sometimes cause odd glitches. Check Canon’s support website for your specific camera model. If there’s an update available, follow the instructions *exactly*. This is not the time to go rogue and improvise. Wrong firmware can brick your camera, and nobody wants that.
When It’s Not Just a Blip: Deeper Dives
If the basic steps didn’t cut it, you might be looking at something a little more involved. And this is where it gets annoying, because Canon’s official documentation often dances around the specifics, like a politician avoiding a direct question.
The Mirror Lock-Up Mystery
This is one of those settings that sounds technical and is usually buried deep in the menus. If your camera’s mirror is stuck in the ‘up’ position (meaning the mirror isn’t reflecting light to the sensor), you’ll get a red square. Why would it be up? Usually, it’s because you’ve accidentally engaged the ‘mirror lock-up’ mode for cleaning the sensor, and then forgotten to disengage it. It’s a setting designed for long exposures or sensor cleaning, and if it stays engaged, your camera won’t fire properly. I once spent two hours trying to figure out why my new-to-me used Canon 7D wouldn’t shoot, only to find this obscure setting buried under a sub-menu called ‘Shutter Settings’ or similar. The manual explained it, but not in a way that made you think, ‘Ah, THIS is why my red square is flashing.’
How to check/fix: Dive into your camera’s menu system. Look for options related to ‘Mirror Lock-Up’, ‘Exposure Delay Mode’, or ‘Self-Timer/Remote Control’ settings. Ensure that any setting that keeps the mirror locked up is turned OFF. Sometimes, it’s tied to the ‘Live View’ shooting mode, so switching back to viewfinder shooting can help reset it. For my 7D, it was a dedicated button combination I had accidentally triggered. (See Also: How To Set Up Trace Camera )
The ‘err 70’ or ‘err 50’ Specifics
These error codes are slightly more specific and can point to internal communication or DIGIC processor issues. Err 70 often relates to a general internal error, while Err 50 can point to specific issues with the DIGIC processor or its communication with other components. It’s like the camera’s brain is having a brief overload or a bad dream. In these cases, the basic battery and card resets are still your first port of call. But if those fail, it’s less about a user-fixable setting and more about a potential internal component issue. Consumer Reports has noted in their camera testing that while Canon generally has good reliability, internal electronic faults can occur in about 2-3% of units over their lifespan, often manifesting as persistent error codes.
Power Issues: Beyond the Battery
Sometimes, the issue isn’t the battery itself, but the camera’s power management system. This can be triggered by a slightly faulty internal circuit or even a power surge if you were charging the battery. If you use an external battery pack or a dummy battery for long shoots, check those connections and the power source itself. A faulty power adapter can send wonky signals to the camera, causing it to throw up an error. This is like trying to run a high-performance engine on slightly off-spec fuel; it just won’t perform correctly.
When to Call in the Pros (or Just Accept It)
If you’ve tried everything – battery out, battery in, new card, old card, cleaned contacts, checked lens mount, toggled mirror lock-up, updated firmware, and you’re still staring at that infernal red square, it might be time to face facts. For persistent errors, especially the more cryptic ones like Err 70, it often means a trip to a professional repair shop or contacting Canon support directly.
What to Expect: Repair costs can vary wildly. For a simple sensor cleaning or a minor connection fix, you might be looking at $50-$150. But if it’s a deeper internal electronic issue, the repair bill could creep up towards $200-$300, or even more if it’s a complex board replacement. At that point, you have to ask yourself if it’s worth it compared to putting that money towards a newer body. I once had a Canon 60D that developed a persistent red square after about five years of heavy use. The repair quote was almost half the cost of a used replacement, so I ended up selling it for parts.
The Contrarian View: Everyone tells you to immediately send it to Canon. But honestly, for many of these common errors, especially the red square, I think Canon support can sometimes be overkill or just send you through a generic troubleshooting tree that you’ve already done. Unless it’s a truly catastrophic failure, a good independent camera repair shop, one with actual technicians who have been doing this for years, can often diagnose and fix it for less money and faster turnaround. They’ve seen it all. Think of them less as corporate service centers and more like the grizzled mechanics who can fix your classic car by feel.
