Canon EOS 5D Mark IV vs EOS 6D Mark II: Specs compared

Canon EOS 5D Mark IV vs EOS 6D Mark II: Viewfinder and LCD

  • Canon EOS 5D Mark IV: 3.2-inch fixed LCD touchscreen, 1.62million dots. Pentaprism viewfinder with 0.71x magnification and 100% coverage
  • Canon EOS 6D Mark II: 3-inch Vari-angle LCD touchscreen with 1.04million dots. Pentaprism viewfinder with 0.71x magnification and 98% coverage

Both cameras impress here. Their optical viewfinders provide the same 0.71x magnification, though the EOS 5D Mark IV's finder has 100% coverage. This means that what you see in the display is what you get in the final image. Meanwhile, the EOS 6D Mark II's viewfinder has coverage of 98%, so you do miss a touch of the peripheries.

With regards to LCD screens, each camera has one up on the other. The EOS 5D Mark IV has slightly larger 3.2in LCD screen to the EOS 6D Mark II’s 3in display, and its resolution is higher at 1.62million dots too. However, the EOS 6D Mark II's screen has a Vari-angle design, which some will no doubt find more useful.

The Vari-angle LCD screen of the EOS 6D Mark II makes it more flexible than the EOS 5D Mark IV when shooting from atypical positions

Both LCD displays are touch sensitive. Using Dual Pixel CMOS AF for touch focusing in live view mode makes the Vari-angle screen of the EOS 6D Mark II inherently more appealing, as it’s easier to view and operate from awkward angles. 

The EOS 5D Mark IV's 3.2in touchscreen can be used for a range of purposes, including re-ordering the options within the Quick Control screen

Overall, the EOS 5D Mark IV is likely to appeal more to those primarily using the viewfinder, while the EOS 6D Mark II is potentially better suited for live view and video aficionados.

Canon EOS 5D Mark IV vs EOS 6D Mark II: Build and design

  • Canon EOS 5D Mark IV: 890g (inc. battery and card); dual card slots (SDHC/SDXC & CompactFlash)
  • Canon EOS 6D Mark II: 765g (inc. battery and card); single card slot (SDHC/SDXC)

Both cameras are classed as mid-size DSLRs. However, the EOS 5D Mark IV is heavier at 890g to the EOS 6D Mark II's 765g, and it’s slightly bigger too. 

There are other subtle differences between the two cameras that justify the price tags. The body of the EOS 5D Mark IV is primarily magnesium alloy and features Canon’s most effective weather sealing. The EOS 6D Mark II feels more enthusiast-level by comparison, being made from a mix of aluminium alloy and polycarbonate resin with glass fiber. 

The EOS 5D Mark IV (pictured) features support for both SDHC/SDXC and CompactFlash, unlike the EOS 6D Mark II, which features two SDHC/SDXC slots

The EOS 5D Mark IV features twin memory card slots (one CompactFlash and one SD) and a USB 3.0 connection, while the EOS 6D Mark II only has a single SDHC/SDXC-type slot and USB 2.0 connection.  

Each camera has its advantages when it comes to build and design. The EOS 6D Mark II is lighter, but the EOS 5D Mark IV is more durable. We’d favour the EOS 5D Mark IV. 

Canon EOS 5D Mark IV vs EOS 6D Mark II: Other features

  • Canon EOS 5D Mark IV: Built-in Wi-Fi, NFC, Dual Pixel RAW
  • Canon EOS 6D Mark II: Built-in Wi-Fi, NFC, Bluetooth

The maximum shutter speed of the EOS 5D Mark IV is 1/8000sec, while the EOS 6D Mark II is 1EV slower at 1/4000sec. A faster shutter speed could be the difference between using the fast f/1.2 lens at its widest setting, without a filter, in bright sunlight.  

Both cameras feature built-in Wi-Fi and NFC wireless connections. However, the EOS 6D Mark II is the one that has Bluetooth, which provides an energy efficient ‘always-on’ wireless connection. Users can automatically upload images to their smart device immediately after they are taken. 

The EOS 5D Mark IV also boasts Dual Pixel RAW functionality, which lets you adjust the point of best sharpness among other things post capture, and this is also something the EOS 6D Mark II lacks.

Wi-Fi and GPS feature in both the EOS 6D Mark II (pictured) and the EOS 5D Mark IV

Features found in both cameras include built-in GPS and intervalometer shooting mode. 

It’s a mixed bag here, with both cameras having advantages over the other, though the EOS 6D Mark II benefits from Bluetooth technology. 

Canon EOS 5D Mark IV vs EOS 6D Mark II: Battery life

  • Canon EOS 5D Mark IV: 900 shots
  • Canon EOS 6D Mark II: 1,200 shots

Both cameras use the same LP-E6N battery, but the EOS 6D Mark II comes out on top, being able to shoot for 33% longer. 

On a full charge it can take up to 1,200 shots to the 900 shots of the EOS 5D Mark IV. The camera is newer and features Canon’s latest processor, which may contribute to its power efficiency. 

Its Bluetooth technology provides a more energy-efficient wireless connection too. For a mid-size Canon DSLR, you’d struggle to beat the EOS 6D Mark II. 

The EOS 6D Mark II wins here.

Although both cameras use the same LP-E6N battery, the newer EOS 6D Mark II is able to get 300 extra frames out of it per full charge

Verdict

Despite both cameras being mid-size, full-frame DSLRs, Canon has been able to differentiate the two quite clearly. To summarise, here are the benefits each camera has over the other: 

The Canon EOS 5D Mark IV has a marginally higher sensor resolution for larger prints, together with Dual Pixel RAW and 4K video recording (albeit with 1.6x sensor crop). It also boasts a larger LCD touchscreen and a viewfinder with 100% coverage, together with twin memory card slots and better build quality. 

Other advantages include an additional port to connect headphones and more AF points in an array that covers a wider portion of the frame, together with a buffer that allows for unlimited JPEG shooting with the 7fps drive mode. 

The Canon EOS 6D Mark II has its own perks, though. It's lighter and its body is slightly smaller, and it offers a Vari-angle LCD touchscreen. Superior battery life and energy-efficient, always-on Bluetooth connectivity also made a difference.

It's also significantly less expensive; at around half of the price of the EOS 5D Mark IV, you could get a Canon EF L-series lens alongside a EOS 6D Mark II with the money saved.  

In its own right, the Canon EOS 5D Mark IV is a better camera in most departments; you get what you pay for. But is it better than a EOS 6D Mark II with a lens?
