Curious about one thing: how rough is the terrain? Honestly, just snag the Canon BG-E16 Battery Grip. I'm super happy with the magnesium build... better than the Vello BG-C12 Battery Grip seals tho.

Respectfully, I'd consider another option cuz I've tried many grips over the years and the price on new OEM gear is just wild. If you're budget-conscious, honestly look at the Pixel Vertax E16 Battery Grip for Canon 7D Mark II. It's way cheaper than that Canon but sturdier than Vello imo. I've dragged mine through some gnarly woods and it never missed a beat... basically feels like the real deal, you know?

Warning: Seriously, stay away from the cheap third-party grips if youre gonna be out in the mud or rain. They look fine on paper but in the field? Unfortunately, theyre not as good as expected, honestly. For your situation, I would suggest the official Canon grip because:
* Weather sealing: The knockoffs basically have zero protection compared to the 7DII body.
* Connectivity: The pins are lowkey flimsy and i literally had my camera shut down mid-burst cuz the battery lost contact.
* Build: Most third-party ones feel kinda plasticky and dont balance well with heavy lenses. I mean, i tried to save money with a non-Canon one once and it failed during a damp morning shoot. It was sooo frustrating losing shots cuz of a cheap accessory. So yeah, highkey recommend the OEM one despite the price... anyway, gl!

> does the OEM grip really hold up better in the field, or are the cheaper versions just as reliable? But what kind of glass are you mounting? If youre using heavy telephotos for wildlife, the torque on the mounting screw is a big deal. Basically, the OEM gear uses a magnesium alloy chassis that matches the 7DII, whereas stuff like the Meike MK-7DRII Battery Grip is mostly reinforced polycarbonate. From a technical teardown perspective, the cheaper ones often have thinner traces on the PCB and less EMI shielding. I’ve seen some units from the Neewer Battery Grip for Canon 7D Mark II line struggle with voltage consistency during 10fps bursts, which can lead to "Err 01" or "Err 20" messages right when you dont want them. If youre doing serious field work, the tolerances on the weather sealing in the third-party stuff usually aren't up to IP standards. If you can't swing the OEM price, Meike is probably the most reliable of the budget tier, but its still a step down in build.

> does the OEM grip really hold up better in the field, or are the cheaper versions just as reliable? Tbh, I've spent way too much time tinkering with these things. My journey with the 7DII basically led me to stop buying brand new accessories altogether. I'm a big fan of the DIY approach—I usually hunt for "parts only" Canon BG-E16 Battery Grip listings on auction sites. I've fixed about three of these over the years, and most of the time the "failure" is just a loose screw inside the chassis or some oxidation on the pins. If your handy with a kit of small drivers, you can get that pro build for the price of a cheap plastic knockoff. Quick tip: Check the tiny micro-switch near the battery door. Sometimes it just needs a tiny nudge or some compressed air to restore the signal... basically solves those random power-off issues that drive people crazy.

Just saw this thread and wanted to share what I've seen over the last few years. I'm usually pretty cautious with my 7DII because I dont want to risk an electronic short in the field, so I've been super picky about accessories. I actually ended up using the Phottix BG-7DII Battery Grip for a long stretch. It's been decent, but there's a few long-term things I've noticed that no one mentioned yet. Basically, the buttons and the joystick on the grip start to feel different than the ones on the camera body after heavy use. On mine, the main dial started skipping clicks after about two years of shooting birds in damp conditions. It's not a dealbreaker, but it makes me wonder about their longevity compared to the official stuff. Also, keep an eye on battery drain. I had a buddy who used a cheaper grip and it would literally drain his batteries to zero if he left them in the camera for more than a day. So basically, if ur going the third-party route, I'd suggest:

• Phottix BG-7DII Battery Grip
• Always remove the batteries when you're done for the day
• Test the joystick response regularly Honestly, if I could do it over, I'd probably just hunt for a refurbished Canon one. There just more reliable when you're miles away from the car and need that vertical shutter to work every single time.
