Nikon Z7 / Z6 vs Sony A7R III Review, Specs, Lenses, and More

The team here at PHLEARN has been a big fan of the Sony A7R III and we love to shoot photography tutorials with it, so we are just as interested as you might be about the new Nikon Z7 and Z6 and how they stack up.

Rather than doing a traditional review, we are going to just give you the highlights and link to helpful articles from around the web if you want to take a deeper dive.

Key Differences & Specs

First and foremost, let’s be clear that Nikon knows exactly what they are up against. They weren’t going to enter the high-end mirrorless race without a true contender to take on Sony A7 line.

Z7 / Z6 Price at Launch

Nikon Z7 $3,396.95

Nikon Z6 $1,996.95

Sony A7R III (currently) $2,998.00

Release Date

September 2018. These dates sometimes shift as well know. You can pre-order from B&H currently for an expected Sept 27th ship date.

Resolution

The Nikon and Sony both use back-illuminated sensors, but the Z7 packs an amazing 45.7MP compared to the A7R III’s 42.2MP. Which if you are counting your pixels is the same as the Nikon D850.

Size and Weight

Both cameras are heavily armored with magnesium alloy front, top, and backs with weather sealing throughout.

When it comes to weight, they are nearly the same with the A7R III coming in at 657 grams (1.44lbs) and the Z7 at 675 grams (1.48lbs).

The body on the Sony is smaller (126.9 x 73.7 x 95.6mm) vs (134 x 67.5 x 100.5mm) on the Z7, but the Nikon has a larger handgrip which does sound appealing to us, given the Sony is a little awkward when attached to a larger lens.

Burst Shooting

The Sony A7R III comes in at 10fps, besting the Nikon Z7 at 9fps.

ISO Range

Very slight edge to Sony on this one at 100-32,000 (50-102,400 extended) compared to the Nikon at 64-25,600 (32-102,400 extended).

Autofocus

While both cameras boast hybrid on-chip phase detection and contrast AF, the Nikon Z7 has 493 phase detection AF points (over 90% of the image area) and Sony’s A7R III has 399 phase detection points (over 68% of the image area).

One key point to remember is that Sony does have the EyeAF feature, which many portrait and event photographers love for its eye detection.

Electronic Viewfinder (EVF)

Pretty much tied here. 0.5-inch electronic viewfinders all around. 3.6 million dot display with 60fps. Nearly the same magnification. Hard to spot much of a difference.

4K Video (and 8K* time-lapse)

You can shoot 4K video on both the Sony and Nikon, but the Z7 does have a one new trick up its sleeve.

The Nikon shoots UHD 4K (3840 x 2160) in full-frame area or DX crop area at 30p, 25p, or 24p frame rates. It can do 1080 HD at 120p for slow motion as well.

You might say, “well so can the Sony! and you’re right. But the Z7 brings a fun new feature to allow for both 4K AND 8K time-lapse movies up to 9,999 frames in total.

Storage / Memory Cards

The Nikon Z7 & Z6 use a single XQD card slot. You might have just read that sentence and gone, “What the heck is an XQD card???” Well, it’s a ridiculously fast high-capacity storage format currently only manufactured by …..drumroll please….. Sony. (It’s a small small world right now in the high-end mirrorless space.)

For now Sony will continue to use dual SD cards for the A7 line, but we’re making a pretty strong prediction that’s going change. There are even rumors that Nikon wants to be able to support the CFExpress in the future as well.

Battery Performance

The Nikon Z7 / Z6 share the same battery at as the Nikon D850, but a slightly newer version called the EN-EL15b. It only pulls in 330 shots, which is surprisingly well below the Sony A&R III’s 530-shot battery life. In real-world testing we wouldn’t be surprised to see the Nikon perform better than 330 shots, but that number is surprisingly low.
