I saw very few reviews for this with a Canon T5i, so here goes.
1) Does it work?
Oh yeah, baby! Does it ever! Switch your T5i to Remote/Timer mode, point the remote at the camera, and press the button.
You'll hear the camera focus, then beep, and then shoot.
Also, when you press the button, the T5i flashes this yellow light on the front of it to let you know that it got the signal (very cool! I love Canon!)
2) Does it work on Vidoe mode?
Yep. Absolutely! Push your T5i power switch over to video mode, point the remote at the front of the camera, and press the button. The camera is now taking video. Press it again and it camera stops the video.
When starting video, the yellow light on the camera fires to let you know it got the signal and started the video. Oh yeah! Love it!
Also, when you press it again to stop the video, the camera is smart enough to WAIT until AFTER the video has stopped BEFORE flashing the little yellow light. SWEET!! Again, Canon, you rock!
I was able to fire the lens with the remote from about 17 feet away from the camera. Any further than that & the signal didn't make it. Step back from 17 feet, nope. Won't work. Step forward into the 17 foot radius. Yep. Works great!
I tried this in a long hall way and with the camera elevated, on a desk, down on the floor, etc....basically, if I'm within 17 feet of the camera, the camera could recognize the signal.
Angle Of Firing:
(Looking at back of camera)
Left of camera - Sometimes. If your angle is high enough up, the camera sensor can detect it & fire
Right of camera - Yep. Every time. Even when I was slightly behind the right side of the camera it caught the signal & fired
Directly behind camera - Sometimes. If you're back a ways (say about 10") it caught the signal. Within 1"? Sometimes
Directly above camera - Yep. Every single time. Even when I was slightly behind and above the camera. It caught the signal
Directly below camera - For the most part. If I was below & on the left slightly, the lens blocked the signal, but to the right or directly on center, yep. Every time.
Think of the sensor on the camera like a mini fish-eye lens. If it can grab the IR signal from the remote, it's gonna fire. Especially if you bounce it off of something. ie. I pointed the camera at a white board, stood behind it, fired the remote, bam! The camera fired.
Same thing when I pointed the camera at an iMac & I fired the remote at the iMac. Camera fired.
Granted, this is all within close range, but you get the idea. Basically, if the camera is on a tripod and you're anywhere NEAR the camera and point the remote at it & press the button, you've got a REALLY GOOD CHANCE that it'll fire.
Very, very, very cool! I'm totally sold!
Stupid, corny fact.
The remote will work THROUGH the included felt bag. I put the remote in the bag, pointed it at the camera and pushed the button and ba da bing, the yellow light flashed & the shutter triggered! How cool is that? It doesn't work very far away from the camera that way (duh! The lens on the remote is covered by a bag), but I was still amazed that it worked at all.
It won't "hold the shutter button half-way down to focus but not fire" the camera. In other words,if you press the button and if the camera senses it, it's the equivalent of pushing the shutter button down ALL THE WAY down and it's going to attempt to focus and shoot a picture or start the video. My corded shutter release has a "half-way down" option to auto focus but not shoot. This doesn't; push the button on this remote and you're fully committed. It's going to take a picture or start video. No biggie, but something you should be aware of. I knew that going in, so doesn't bother me a bit.
Super Cool Awesome Feature:
Because you're not TOUCHING the camera to trigger the lens, this means that you're also not knocking the camera back out of focus or jiggling the camera and causing problems. Instead, the camera can still be sitting rock steady on the tripod and snap the shutter without you knocking it out of focus. This is ESPECIALLY awesome when you're taking photos without the flash on (ie. Macro photogs I'm talking to you!). I shoot product photography for my business and this little feature will be PRICELESS to me. I usually spend a bunch of time getting my shot ready, getting the camera in focus and then want to fire the lens WITHOUT TOUCHING THE CAMERA. This will let me pull that off....from 17 feet away too! Oh yeah! Think of the possibilities for macro shots! ie. butterfly FINALLY lands on the leaf you have the camera focused on. Now you can be away from the camera (not scaring said butterfly away) and still trip the lens. Can you say REALLY REALLY COOL!? (Note. If you do this, go into your camera settings & shorten the timer length to trip the lens. All that beeping could scare the butterfly away, but if you have it set to say 1 second. BAM! Ya got your super awesome butterfly shot from 17 feet away! You are now AWESOME!!! (and all because you bought this cheap little remote). Think of the possibilities!!
The remote is about 2.5" long x 1 1/8" wide x 1/4" tall. It weighs less than a gram (I couldn't get my gram scale to even register that it was on it, but my scale registers in whole gram increments.
How It Feels In Your Hand:
Like Butta! Ok, well, maybe not butter, but seriously, it fits really well in my "average guy" hands. Think of your typical key-fob on the end of a key chain for a car and you've got an idea of it's size & how it feels in your hand. It's a little thinner than a key-fob but probably weighs about the same. The big gray button is easy to feel when it engages as there's a soft "click". The button cover is a nice feeling rubber material too.
It'd be easy to use to take a self-portrait remotely too. ie. You can go get set up with your family & say "CHEESE", press the button, and then have time enough to hide the button in your hand (or even pocket) while the camera starts beeping and then the shutter fires. Great for self-family portraits! Cool! (It won't stop Jr from sticking his tongue out or get baby sister to actually LOOK at the camera, but at least YOU are in the picture when the shutter button triggers instead of running like the wind to try & get re-positioned into the shot--for that feature alone, this thing is awesome!).
Mine came with a Maxell CR2025 3 V battery. It had a clear plastic cover I had to pull out to engage the battery contact with (so the battery doesn't go dead while it's on Amazon's shelf I guess). It was kind of a pain to pull the battery all the way out of the remote, but the only reason I did it was to see what kind of battery it is. If it's like most of these remotes, it'll probably last me several years before I ever have to swap the battery out, so not a big deal. It's definitely not going to "fall out" as it's in there tight. It did slide right back into the remote though really easily.
Meh...it's not too expensive looking or feeling. It's your basic molded plastic remote, but hey it's cheap & I don't need an expensive looking for feeling remote. I wouldn't call it "Canon Camera Body or Camera Lens Quality Plastic", but it's not the cheap "gonna fall apart because it's so thin" plastic either. It'll do me quite well for several years.
Would I Buy It Again?:
Oh heck ya! In a heartbeat! For the price, you really can't beat this thing. I wish I would've bought it YEARS ago so I could've used it with my Canon XSi (which it also worked with by the way).
Do I love it?
Oh yeah! Beats the crap out of using my stupid corded shutter release button. I can now be up to 17 feet away from my Canon T5i and trip the shutter! Buy one! You'll love it!
