SONY Sony Alpha a7R IV Mirrorless Digital Camera Review
The Sony a7R IV's 61MP sensor and top-tier autofocus make it a stills photography monster, but its video features and battery life hold it back from being a true all-rounder.
Overview
The Sony Alpha a7R IV is a 61MP powerhouse that's built for one thing: taking absolutely stunning photos. It lands in the 96th percentile for autofocus and the 93rd for build quality, which tells you right away this isn't a toy. It's a serious tool for photographers who need every pixel to count. The 15-stop dynamic range and ISO range from 50 to 102,400 give you insane flexibility in the field, whether you're shooting a bright landscape or a dimly lit interior.
Performance
Let's talk about that autofocus. With 567 phase-detection points and Real-time Eye AF for humans and animals, it's in the top 4% of all cameras for locking onto subjects. That's a huge deal for travel and wildlife shooters. The 10fps mechanical burst at full 61MP resolution is solid, sitting in the 83rd percentile. The sensor itself is a monster, scoring in the 79th percentile. Pair that with 5-axis in-body stabilization in the 91st percentile, and you've got a camera that can handle shaky hands and fast-moving subjects with ease. Just know the video specs are more of an afterthought, landing in the 33rd percentile.

Value & Pricing
The price is all over the map, from $2130 to $3298 depending on the vendor. That's a massive $1168 spread. If you can find it near the low end, it's an incredible deal for the stills performance you're getting. At the high end, you're paying a premium that's harder to justify unless you absolutely need that 61MP sensor right now. Shop around.
vs Competition
Compared to the Canon EOS R7, the a7R IV smokes it in pure resolution and dynamic range, but the Canon will run circles around it for video and has much better battery life. The Fujifilm X-S20 is a better all-rounder for hybrid shooters who want great video and photos, but it can't touch the Sony's sensor detail. The Pentax K-3 Mark III is a DSLR beast with even better build and weather sealing, but its autofocus system isn't in the same league as Sony's mirrorless tech. You pick your trade-off: ultimate stills detail with the Sony, or more balanced performance elsewhere.
Verdict
This is a specialist's camera. If your primary goal is capturing the highest resolution, most detailed still images possible—for landscape, portrait, or travel photography—and you don't care much about video, the a7R IV is a phenomenal choice. Its autofocus and build quality are among the best. But if you need a do-it-all camera for both photos and video, or you prioritize a tilting screen and long battery life, look at the competitors.
