However, they cater to slightly different needs and budgets. The a6700 is priced at $1,898.00, while the a7 IV comes in at $2,049.00, making the a6700 about 7% cheaper.
Sensor and Image Quality
The Sony a6700 features a 26MP APS-C format Exmor R back-illuminated CMOS sensor, delivering excellent image quality suitable for various shooting scenarios. In contrast, the Sony a7 IV boasts a more advanced 33MP full-frame Exmor R sensor. This gives the a7 IV an edge in terms of resolution and dynamic range, with over 15 stops of latitude compared to the a6700. The sensor differences highlight the a7 IV's capability for capturing finer details, particularly in low-light conditions or high-contrast scenes.
Autofocus and Tracking
Autofocus performance is a crucial factor for any camera user. The Sony a6700 features 759 phase detection AF points with 93% coverage, ensuring fast and accurate focusing. On the other hand, the a7 IV elevates this performance with 759 phase detection points and an impressive real-time Eye-AF system for humans and animals, significantly enhancing its tracking capabilities for both stills and videos. This makes the a7 IV a better choice for those focused on capturing moving subjects with precision.
Video Capabilities
For video enthusiasts, the a6700 supports 4K recording at up to 60p, with 6K oversampling providing top-notch quality. Meanwhile, the a7 IV also supports 4K recording at 60p, but with additional features such as 10-bit 4:2:2 internal recording and advanced movie features like Focus Map and Breathing Compensation. The a7 IV's superior video capabilities make it well-suited for filmmakers or content creators who require the best available technology for video production.
Design and Usability
Both cameras are designed with user experience in mind, but they differ in specific usability features. The a6700 includes a vari-angle touchscreen LCD monitor, offering enhanced flexibility for shooting from various angles. In contrast, the a7 IV features a 3.68 mega-dot Quad-VGA OLED viewfinder with a 120 fps refresh rate, providing a high-quality visual experience for composing shots. The choice between them will depend on whether a user prioritizes a versatile display or a high-quality viewfinder for framing images.
Battery Life and Performance
Battery performance is vital for long shooting sessions. The Sony a6700 can shoot more than 1000 JPEG images at 11 fps, showcasing its efficiency. Conversely, the a7 IV allows continuous shooting at up to 10 fps with continuous AF/AE tracking, accompanied by robust performance for extended usage. The longer battery life of the a6700 makes it a more practical choice for users who prioritize longevity in their shooting sessions.
Bundled Accessories
Both cameras come with valuable bundles that enhance their usability. The a6700 includes a Deco Gear Photography Bag, an extra battery, a dual charger, a flash, and a software kit, providing a comprehensive package for beginners. The a7 IV, on the other hand, comes with a similarly useful bundle consisting of a Deco Gear case, a professional tripod, and additional batteries and chargers. The difference in accessories is minimal, but the a6700's bundle adds more immediate value for those starting out.

This $151 difference makes the a6700 about 7% cheaper, offering a more budget-friendly option without sacrificing too much in terms of quality. For users who are cost-conscious yet still desire high performance, the a6700 presents an attractive alternative.
