Question: Will this work with Canon 7D MarkII?
Document: Works in my canon 7D and my canon 6D. Great if you like to do time lapse photos or leave the camera on for long periods. A friend of mine got the cheap knock-off, it doesn't work well at all.
It woks perfectly, I use it for emergency with my Canon 7D. No problem to plug it. The cable is a little short buy I always carry my extension in the bag.
I have both a Canon 5D Mark II and a Canon 7D. This works on both. I use it mostly for times when I am cleaning the cameras or installing updates. Well worth the purchase.
I need to run my 7D for several hours, and it was unattended. The solution was the Camranger and this Canon power supply. It's a little pricey, but it did the job and did not introduce and noise or excessive heating into my set up, so it was great!! !
This is also a great tool to use if you preview your shots in Live View mode, do a lot of studio work, shoot a ton of video AND mostly, while you're charging your batteries. Don't get me wrong, the Canon 5D is great on battery usage, but you should ALWAYS have the power you need, when you need it...and extra Compact Flash and SD cards too.The cord from the AC outlet to the converter is six feet.
Love doing studio work, mostly timelapse stuff.Not having to use batteries is great.Kinda pricey, and not sure what kind of electronic wizardry actually happens in the official canon variant of this part, but I like that it is genuine part and my peace of mind is well. The high price a little unfortunate, you might want to choose the cheap knockoff instead, but then risk compatibility issues (if any).
This has become an essential item if you are recording a lot of video. After a long day of interviews and trying to keep batteries charged without delaying our shoot I decided enough is enough. I would have purchased this sooner but $120 is pretty steep for an AC adapter. It does the job but I don't see anything noteworthy about the build quality to justify the price tag. Works fine on both a Canon 5D and 7D.
Got three of these so we could use them with our 5Ds for doing lots of filming. There isn't much to say other than the fact that they work perfectly. Instead of needing tons of batteries, just get some AC adapters and be done with it.
Got this for the 7D. Worked perfect. Have not had for years so can't tell yet on durability, but appears to be high quality. Didn't want to risk an expensive camera with a cheap knock off.
Delivered as predicted, worked as expected an so far seems to be a very good product.I have used it in my 7D for 2 and 3 hour time laps and it worked perfectly.
Answer: It's supposed to. The 7D mark II can or at least should be backwards compatible with the LP-E6 batteries and gear. That's per the canon website. The LP-E6 and its "N" counter part only differ by the chip used on the battery and a slight capacity increase.
