Sony A7R II vs. Sony A580: The Definitive Comparison for Photographers Ready to Upgrade or Start Strong

Choosing the right camera can be daunting, especially when comparing models separated by technology generations and design philosophies. Today, we’re putting two Sony cameras head-to-head: the professional-grade Sony A7R II, a full frame mirrorless powerhouse introduced in 2015, versus the entry-level Sony A580, a DSLR newcomer from 2011.

As photographers who’ve extensively tested cameras from all categories, we’ll examine these two in practical terms you care about - image quality, autofocus, handling, video, and more. Whether you’re stepping into Sony’s ecosystem for the first time or aiming to upgrade an aging DSLR, this hands-on, honest assessment will help you confidently decide which camera best suits your creative journey.

So, let’s dive in.

First Impressions: Size, Build & Ergonomics

The physical feel of a camera is more than just comfort; it affects how you interact with the device during shoots, long or short.

The Sony A7R II, despite packing a full-frame sensor and advanced stabilization, is noticeably more compact and lighter, thanks to its mirrorless design. Its SLR-style grip strikes a nice balance between compactness and ergonomic comfort. Plus, robust weather sealing makes it your go-to for outdoor and travel shoots without worrying about dust or light moisture.

The Sony A580, while bulkier and slightly heavier, benefits from a traditional DSLR feel with a deep grip and tactile controls, which many new DSLR shooters appreciate for stability. However, without weather sealing, rough conditions require caution.

Ergonomically, both cameras offer tilting 3.0-inch screens but with different resolutions and interfaces, which we’ll explore later.

Imaging Core: Sensor and Image Quality

One of the biggest leaps between these cameras is in sensor technology and imaging capability.

The A7R II’s full-frame BSI-CMOS sensor delivers outstanding resolution and dynamic range, allowing you to capture highly detailed images with rich tonality. The lack of an anti-aliasing filter preserves sharpness, making it ideal for large prints, commercial work, and high-end landscape photography.

Its native high ISO settings and expanded boosted ISO offer usable low-light flexibility with impressively low noise, crucial for event, wildlife, and night photography.

In contrast, the A580’s APS-C sensor is smaller, with fewer megapixels (16MP) and features a traditional anti-aliasing filter, which softens fine details slightly but reduces moiré. While it scores well for an entry-level camera, in direct comparison it cannot match the dynamic range or low light prowess of the A7R II.

However, the APS-C sensor has a crop factor of 1.5x, giving extra effective reach to telephoto lenses, helpful in wildlife and sports contexts if you need that reach on a budget.

Autofocus Systems: Speed, Accuracy, and Flexibility

Autofocus performance defines your ability to capture sharp images in dynamic scenarios, from running children to fleeting wildlife moments.

With nearly 400 autofocus points distributed for wide coverage and hybrid phase/contrast detection, the A7R II autofocus is a high-performance system that excels in tracking moving subjects with excellent speed and accuracy. Its real-time eye detection enhances portrait work by locking focus reliably on your subject’s eyes for tack-sharp portraits.

On the other hand, the A580’s 15 AF points with just 3 cross-type sensors is suitable for standard situations but can struggle with erratic moving subjects, limiting its use in fast-paced shooting scenarios.

If you’re into wildlife, sports, or event photography, the A7R II’s advanced AF system will give you the confidence to chase action and get the shot.

Viewfinder and Rear Screen Usability

Precise framing and reviewing shots depends heavily on your viewfinder and LCD screen.

The A7R II’s high-resolution electronic viewfinder shows an accurate exposure preview with 100% coverage, histogram overlays, and focus peaking assists – all invaluable tools for precise manual focusing and exposure control.

Its rear tilt-screen is sharp and responsive, perfect for overhead or low-angle shots. However, it lacks touchscreen functionality, so navigation is via physical buttons.

In turn, the A580 has an optical viewfinder with 95% coverage, which means your final image may include slightly more than what you see - a minor but important consideration for precise composition. It offers a less detailed rear screen and no touchscreen but includes live view on the LCD.

Overall, the A7R II’s EVF and screen provide a far more informative, flexible experience suited to professionals and advanced amateurs.

Build Quality and Environmental Resistance

When shooting outdoors in various conditions, your camera’s durability is crucial.

The A7R II boasts a magnesium alloy body with robust sealing against dust and moisture. This construction lets you confidently shoot in rain, dusty trails, and occasionally harsh environments - a major plus for nature photographers and travelers.

Meanwhile, the A580 has a more plastic-based, less sealing-intensive design. It is fine for casual indoor and fair-weather outdoor use but requires extra care in challenging conditions.

Burst Shooting and Buffer Handling

Capturing fast action often depends on burst rate and buffer depth.

Despite the higher frame rate of the A580 at 7fps, it is limited by its shallow buffer, meaning it slows down more quickly during continuous shooting. The A7R II’s 5fps rate is respectable for a 42MP sensor, and its generous buffer depth lets you hold longer continuous bursts - ideal for sports, wildlife, and decisive moment photography.

Video Capabilities: What Can You Capture?

In today’s hybrid world of photo and video, video specs often influence buying decisions.

The A7R II delivers a fully-fledged 4K video recording capability coupled with professional features such as 5-axis stabilization and headphone audio monitoring, making it a flexible tool for filmmakers and multimedia creators.

The A580 offers solid Full HD video but lacks 4K and headphone support, limiting its video appeal but still being sufficient for casual video projects.

Lens Ecosystem and Compatibility

Let’s talk about lenses - a lifeblood for any camera ecosystem.

• Sony A7R II: Uses the Sony E-mount, compatible with a rapidly expanding range of full-frame and APS-C lenses, including many third-party options. Its mirrorless mount also supports adapters to use legacy lenses with autofocus.

• Sony A580: Uses the Sony/Minolta Alpha mount, a DSLR-focused system with a vast library of lenses, especially older, affordable options.

Both camera systems offer access to over 100+ lenses, but the A7R II fits into Sony’s modern, future-proof lineup where innovation such as compact primes, fast autofocus, and image stabilization is widespread.

Battery Life and Storage

The A580 offers excellent endurance for extended sessions, beating the A7R II by over threefold. If you often shoot all day without charging, this is a big plus.

The A7R II’s more power-hungry sensor and EVF mean battery swaps or spares are commonly needed in the field.

The dual card slots on the A580 provide flexible backup options, absent in the A7R II’s single slot design.

Real-World Performance Across Photography Genres

The gallery above illustrates the A7R II’s superior detail and dynamic range in landscapes and portraits, as well as smooth tracking in wildlife shots. Meanwhile, the A580 shows competent, pleasing color and solid performance in general-purpose shooting - especially for beginners.

Interface, Controls, and Connectivity

While pure specs matter, how you interface with gear affects workflow dramatically.

• Sony A7R II: Modern top and rear control layout with customizable dials and buttons. Built-in Wi-Fi and NFC allow instant wireless image transfer and remote control. Full-size HDMI port aids external monitors.

• Sony A580: More traditional DSLR control layout with dedicated buttons but fewer customization options. No built-in Wi-Fi, but Eye-Fi card compatibility allows wireless uploads. HDMI port is present but tends to be mini.

The score comparison above highlights the A7R II overwhelmingly outperforms the A580 in almost every technical arena except battery life and price.

Price to Performance: Where Does Your Budget Go?

In absolute terms, the A7R II requires a much higher investment, but it grants access to pro-level tools and quality that serve serious amateurs and professionals alike. The A580 appeals to budget-conscious photographers starting out or those with staple photo needs on a tight budget.
