So I finally bit the bullet and upgraded to the 5D Mark IV after shooting with the Mark III for like seven years and I thought I knew exactly what I was doing but honestly this thing is a different beast and Im getting so frustrated with my current setup. My logic was that I could just carry over all my old gear and be fine but the battery life is just... awful? I'm doing a huge wedding shoot in Chicago next month and I realized during a test run today that the 4K video just shreds the standard LP-E6 batteries Ive had forever. I was thinking maybe I need the BG-E20 grip but the price tag is making me wince after spending so much on the body. Plus the buffer is lagging like crazy when Im shooting high-speed bursts and Im starting to think my old SD cards just arent cutting it anymore even though they worked fine on my older bodies. Im stuck between getting better CF cards or just a massive pile of new batteries and maybe a screen protector that actually works for the touchscreen because I keep accidentally hitting settings with my nose. What are you guys actually using to make this thing reliable for a long day? Im trying to keep the extra spend under $400 if possible because my bank account is screaming at me...

Forget the expensive grip for now. Just get a few fresh batteries instead to be safe. I would suggest picking up these to stay under budget:
- Canon LP-E6N Lithium-Ion Battery Pack for reliability
- SanDisk Extreme Pro 128GB CompactFlash Card 160MB/s for the speed
- Vello GSP-C5D4 Glass Screen Protector for the screen Make sure you test everything before the big day so there arent any surprises.

To add to the point above: the battery drain on the Mark IV is definitely a step up from older models, especially when you're messing with 4K or leaving the GPS on. I've been extremely satisfied with the Duracell DR9943 LP-E6 Replacement Battery as a budget-friendly backup. It's reliable for long wedding days and hasn't given me any communication errors with the body. Honestly, no complaints so far and they hold a charge well. Regarding the buffer lag, you gotta remember that the SD slot in the 5D IV is only UHS-I. If you're shooting to both slots for redundancy, the slower SD card is gonna throttle your write speeds every single time. It's a technical bottleneck. I switched to using the Lexar Professional 1066x 128GB CompactFlash Card for my primary storage and noticed a huge difference in how fast the buffer clears. It's way cheaper than some other pro brands but performs solidly for high-speed bursts. It's a methodical way to fix the lag without overspending. For the touchscreen issue, I'm happy with just toggling the touch sensitivity in the menu, but a deeper eyecup like the Hoodman Hoodeye Eyecup for Canon 5D Mark IV helps keep your nose off the glass. It makes a big difference when you're tracking subjects through the viewfinder for hours. These small tweaks kept me well under that $400 limit while making the camera actually reliable for wedding work. Basically, prioritize that CF card speed if you're doing lots of bursts.

Agreed, the power draw is a different beast compared to the older bodies. This actually reminds me of when my cousin tried to shoot a documentary in the desert with similar gear. He brought a bunch of old equipment that just couldnt handle the heat and everything started glitching after ten minutes. He spent more time trying to cool his bags with ice packs than actually filming anything. It was a complete disaster to watch.

I've tried many setups over the years, and honestly, I'm gonna disagree with the idea of buying a pile of cheap batteries for a wedding. When you're shooting a big gig in Chicago, you really dont want a generic battery dying or giving a communication error right during the vows. In my experience, the 5D IV is a beast but it's super picky about power and data. Here's how I'd spend that $400 to actually make it reliable:
- Skip the standard batteries and get two Canon LP-E6NH Lithium-Ion Battery packs. They have a higher capacity and handle the 4K drain way better than the older versions.
- The buffer lag is almost certainly your SD card. The SD slot in that camera is slow compared to the CF one. Switch your primary recording to a ProGrade Digital CF 128GB Memory Card. It's much more robust for high-speed bursts.
- To fix the nose-touching issue, a screen protector wont really help with the sensor sensitivity. Just go into the menu and set Touch Control to Disable while you're working. If you still want physical protection tho, the Expert Shield Glass Screen Protector Canon 5D IV is the best I've used. Keeping it simple is usually better than having a bag full of random gear that might fail you...
