Feature-by-Feature Breakdown
Image Stabilization
- Sony A7: The a7 lacks in-body image stabilization (IBIS). This means you rely on lens stabilization or a fast shutter speed to minimize blur from camera shake. This can be a disadvantage in low-light situations or when using older, non-stabilized lenses.
- A7ii: The a7II introduces 5-axis in-body image stabilization (IBIS). This significantly improves image quality by compensating for camera shake across multiple axes. This is a major advantage for handheld shooting, especially with lenses that lack stabilization.
- Winner: a7II
Autofocus Performance
- Sony A7: The a7 features a Fast Hybrid AF system, combining contrast-detect and phase-detect autofocus. It’s generally reliable for single-shot AF and can handle some continuous AF, but it’s not as advanced as later models. Performance can lag in challenging lighting conditions or with moving subjects.
- A7ii: The a7II also uses a Fast Hybrid AF system, but it’s improved compared to the a7. It offers faster and more accurate autofocus, particularly in continuous AF mode. This results in better tracking of moving subjects and improved overall usability.
- Winner: a7II
Body Design and Ergonomics
- Sony A7: The a7 has a compact and relatively lightweight body. The grip can feel a bit small for larger hands, and the button layout might feel cramped for some users. The build quality is generally good, but the design is a bit more basic.
- A7ii: The a7II features a redesigned body with a deeper grip, providing a more comfortable and secure hold. The button layout is also improved, making it easier to access frequently used settings. The build quality is also enhanced.
- Winner: a7II
Video Capabilities
- Sony A7: The a7 offers Full HD video recording at up to 60fps. It provides decent video quality, but lacks some advanced features like S-Log profiles for wider dynamic range. It’s suitable for casual video recording but can be limiting for serious videographers.
- A7ii: The a7II also offers Full HD video recording up to 60fps and adds S-Log2 gamma profile for improved dynamic range and flexibility in post-production. The improved IBIS also helps for smoother handheld video.
- Winner: a7II
Sensor Performance
- Sony A7: Both cameras share the same 24.3MP full-frame sensor. This sensor provides excellent image quality with high dynamic range and good low-light performance.
- A7ii: Both cameras share the same 24.3MP full-frame sensor. This sensor provides excellent image quality with high dynamic range and good low-light performance.
- Winner: Tie
Continuous Shooting Speed
- Sony A7: The a7 offers a continuous shooting speed of up to 5fps. This is adequate for some action photography, but it can be limiting for faster-paced subjects.
- A7ii: The a7II also offers a continuous shooting speed of up to 5fps, similar to the a7.
- Winner: Tie
Viewfinder and LCD
- Sony A7: The a7 features an electronic viewfinder (EVF) and a tilting LCD screen. The EVF provides a clear and bright view of the scene, and the LCD is useful for composing shots at different angles.
- A7ii: The a7II also features an electronic viewfinder (EVF) and a tilting LCD screen. The EVF is largely the same as the a7, and the LCD is similar.
- Winner: Tie
Overall Value
- Sony A7: The a7, being the older model, is often available at a lower price point. This makes it a good option for photographers on a budget who still want a full-frame camera. However, the lack of IBIS is a significant drawback.
- A7ii: The a7II offers a significant upgrade in features, particularly with IBIS and improved ergonomics. While it’s more expensive than the a7, the added features justify the price for many users.

Sony A7 Vs A7II Buying Guide
Image Quality and Performance
Both the Sony a7 and a7II deliver excellent image quality, thanks to their full-frame sensors. The a7II, however, benefits from a slightly improved image processing engine, leading to marginally better noise reduction at higher ISO settings and a touch more dynamic range. In real-world shooting scenarios, the differences are subtle, but the a7II holds a slight edge in challenging lighting conditions. The a7 provides excellent results, but the a7II’s refinements make it a better choice for demanding photographers. Both cameras offer a wide range of creative options, allowing for beautiful images.
Autofocus Capabilities
The autofocus systems are a key differentiator. The a7 features a contrast-detect autofocus system, which is accurate but can be slower, particularly in low light. The a7II incorporates a hybrid autofocus system that combines contrast-detect with phase-detect points, significantly improving focusing speed and accuracy. This translates to quicker subject acquisition, more reliable tracking of moving subjects, and a more responsive overall shooting experience. This makes the a7II a better choice for shooting action or fast-moving subjects. The a7 is still good, but the a7II is demonstrably better.
Ergonomics and Build Quality
The a7II boasts improved ergonomics and build quality. It features a redesigned grip that’s more comfortable and provides a more secure hold, especially with larger lenses. The a7, while still a well-built camera, has a slightly smaller grip that some users may find less comfortable for extended shooting sessions. The a7II also benefits from a more robust construction and weather sealing, making it better suited for use in challenging environments. The a7 is still well-built, but the a7II offers a superior handling experience.
Image Stabilization
The a7II includes a 5-axis in-body image stabilization (IBIS) system, a feature absent in the a7. This is a significant advantage, particularly when shooting handheld or using lenses without optical stabilization. IBIS compensates for camera shake, allowing for sharper images and video, especially at slower shutter speeds. The a7 relies on the stabilization of the lens, which limits its effectiveness to lenses with built-in stabilization. The a7II’s IBIS is a major upgrade for image quality.
Video Features
Both cameras offer respectable video capabilities, but the a7II has some advantages. The a7II offers improved video recording options, including more advanced codecs and picture profiles, providing greater flexibility in post-production. It also benefits from the improved autofocus system, which results in smoother and more accurate focus transitions during video recording. While the a7 can record good quality video, the a7II is a more capable video camera overall. Both shoot 1080p, but a7II’s features edge it out.
Price and Value
The Sony a7 is generally available at a lower price point than the a7II, making it an attractive option for budget-conscious photographers. However, the a7II’s added features, especially the in-body image stabilization and improved autofocus, justify its higher price tag for many users. Consider your budget and your needs. If you prioritize image stabilization and faster autofocus, the a7II is the better value, despite its higher cost. The a7 provides good value, but a7II’s features make it a better long-term investment.
