Sony is known to dominate the mirrorless, full-frame, and digital camera market which comes from its long line of "Alpha" variants that have been available for a long time. The Sony a7 III and Sony a7R IV were both old releases from the company, but it still serves as one of the most reliable and top quality devices among its variants.

Sure these two aforementioned cameras are nothing unlike the latest drop from the company, the Sony a1, also known as "The One," which has beat most of its competitors in terms of specifications and performance. However, not everyone can afford that one, as it costs more than $6,000 for its kit package from the company.

Sony a7 III Specs

First off, the Sony a7 III is the eldest camera in this comparison, as the Japanese technology company released this last April 2018, which marks its third year in the industry. It may be an old camera, but it still packs a punch and performance quality that makes other cameras have a run for their money.

The Sony a7 III debuted a 24.2-megapixel, a full-frame 4K HDR video quality, 100 to 51,200 ISO, and also brought a low FPS setting for slow-motion and 10fps continuous shutter. The camera also packs the 4D Focus, along with a top-performing Exmor R CMOS Sensor that is paired with BIONZ X, which completes this camera's package.

The Sony a7 III has a price tag of $1,999.99 for body only, and $2,198 for its 28--70mm kit lens package.

Sony a7R IV Specs

On the other hand, the Sony a7R IV is a camera that was released a year later, and it is meant to be better compared to the a7 III, marking its almost second year in the industry. However, as much as the a7 III, it may be an old device but it still packs one of the heftiest specifications in the mirrorless camera industry.

The Sony a7R IV packs a massive 61.0-megapixel quality with a full-frame 4K HDR photo and video quality, which is mostly marketed to DLSR cameras for shooting clips and films. The device has 100 to 32,000 ISO, 10fps continuous shooting, 4D Focus, 5-axis image stabilization, an Exmor R CMOS Sensor with 61mp and BIONZ X, along with the 5.76 million-dot UXGA OLED Tru Finder to improve image quality.

The Sony a7R IV has a price tag of $3,499.99 for its body-only package, and a $4,896 starting price for its 24-105mm kit lens package from B&H Photo.

Sony a7 III vs. Sony a7R IV: Which is Better?

Several factors play out when choosing the right camera, and that includes its use, number of applicable accessories, affordability, and the like. In terms of performance, the a7R IV beats the a7 III solely because of its 61mp quality, twice the capabilities of the 24.2mp of the older device.

However, it is a massive letdown for a7R IV's ISO range which is significantly lower compared to a7 III which can go up to 51,200. Additionally, a7R IV still packs a hefty price tag, making it $1,500 more expensive than the a7 III.

For image quality, age, and overall usage, the Sony a7R IV is a great purchase for one's first DSLR or upgrade, but in terms of beginners and coming from low-quality DSLRs, the Sony a7 III would suffice.
