Sony's popular full-frame mirrorless cameras rarely go on sale, so if you've been eyeing one, now might be the time to act — multiple models have discounts for Amazon Prime Day. The best deals are on the high-resolution "R" models, with the current A7R IV on sale at $2,998 ($502 off) and the A7R III available for just $2,198 ($602 in savings). You can also find great deals on desirable Sony lenses like the 24-70mm f/2.8 G Master zoom ($300 off) and Sony 24-105 f/4 G zoom ($300 off).
The Sony A7R IV received one of Engadget's highest camera review scores ever thanks to the fast and accurate autofocus, superb high-resolution photo quality, a bright and sharp viewfinder and great handling. I was particularly impressed with the high burst speeds considering the huge RAW file sizes on the 61-megapixel images. It can even handle video reasonably well for a high-res camera. The downsides are a mediocre menu system and high price, but the Prime Day discount helps take the sting off the latter.
The older A7R III offers a lower 42-megapixel resolution, but it's also a highly-rated camera with excellent autofocus performance, 5-axis stabilization and more. And along with the two high-res models, Sony is also offering a $200 discount on its stalwart A7 III ($1,798) and has dropped the price on the aging, but still very useful A7 II model to just $900 — making it one of the cheapest new full-frame cameras you can get.
If you're more in the market for lenses, Sony has you covered there, too. Along with the $300 price drops on the 24-70mm f/2.8 G Master zoom and 24-105 f/4 G zoom, you can grab $100 discounts on highly desirable models like the Sony 50mm f/1.2 G Master ($1,898) and FE 35mm F1.4 GM G Master ($1,298). The sale ends on July 17th but the best deals are liable to get snapped up well before then, so it's best to act soon.
