Sony QX1 vs Sony SLT-A37: An Expert Comparison for Photography Enthusiasts and Professionals

When it comes to choosing a Sony camera from the early 2010s era, the QX1 and the SLT-A37 often come up as intriguing options, albeit targeted at somewhat different users and use cases. Having tested both cameras extensively – from studio portraits to wildlife treks, and fast-paced street shooting to low-light landscapes – I’m going to share a comprehensive side-by-side comparison. We'll dive deep into how each camera performs technically and practically, helping you understand which one might be the right fit for your photographic ambitions today.

Let's pull back the curtain on their sensors, ergonomics, autofocus systems, image quality, lenses, video capability, and more to provide a fair, grounded analysis that respects your time and investment.

First Impressions and Handling: From a Unique Lens-Style to a Compact SLR

At first glance, these two cameras look and feel fundamentally different because they are, by design, addressing distinct photography philosophies.

The Sony QX1 is a “lens-style” camera, launched in 2014, that is essentially a standalone APS-C sensor camera module with no traditional body or viewfinder. It lacks a conventional grip or physical controls and is meant to be controlled wirelessly via a smartphone app. This approach was quite novel then - a compact device aimed at smartphone users who want DSLR-level sensor quality without carrying a separate camera.

By contrast, the Sony SLT-A37, released earlier in 2012, is a conventional entry-level digital SLR with a pentamirror electronic viewfinder and physical controls spread ergonomically across its compact body.

Physically, the QX1 weighs a mere 216 grams and measures 74 x 70 x 53 mm, making it very pocketable and discreet - perfect for travel or street photographers who prioritize minimal bulk. But the lack of a traditional grip, viewfinder, or extensive buttons forces you to interface primarily through your phone, which can be limiting in dynamic shooting scenarios.

The A37, on the other hand, is bulkier (506 g) and measures 124 x 92 x 85 mm, but it offers familiar DSLR ergonomics with a comfortable grip, dedicated exposure dials, and a tilting LCD. For photographers used to DSLR-style handling, the A37 feels intuitive and reassuringly solid.

Personally, for extended shoot sessions, the A37’s physical controls and viewfinder make it far easier to operate efficiently, while the QX1’s compactness is unparalleled but at the cost of traditional tactile feedback.

Control Layout and User Interface: App-Controlled vs Built-In Physical Buttons

Let’s move from raw size to user interaction.

The Sony QX1’s top surface is spare to the point of minimalism, lacking physical buttons aside from a single shutter release and a power switch. Everything else - autofocus, exposure modes, shutter speed, ISO - is handled from Sony’s PlayMemories Mobile app on your smartphone. The touchscreen on the phone provides an interface for tap-to-shoot and menu toggling.

While this allows for smartphone versatility, the disconnect between camera and control can frustrate serious photographers used to instant physical adjustments. On the plus side, the touchscreen app enables quick focus point selection on the live viewfeed.

The Sony A37, however, embraces tactile control. The top plate hosts dedicated shutter speed and exposure compensation dials - a level of direct access missing in the QX1. The rear screen is a 2.6-inch tilting LCD (230k dots), which, although a bit modest by modern standards, offers convenient framing flexibility.

For focus and exposure, the A37 includes comfortable buttons and a 1440-dot EVF with 100% coverage - excellent for composing shots in bright light or when you prefer to keep the camera to your eye.

From a usability standpoint, for spontaneous photography requiring quick adjustments, the A37 wins hands down. The QX1’s reliance on smartphone pairing is neat but somewhat cumbersome for professional workflows or fast-paced shooting.

Sensor and Image Quality: Comparing APS-C CMOS Sensors

Both cameras use APS-C size sensors with CMOS technology but differ in resolution and sensor generation.

The Sony QX1 features a 20.1-megapixel sensor with a 1.6x crop factor, measuring 23.2 x 15.4 mm. This sensor was quite advanced at the time, capturing fine detail with a 5456 x 3632 max resolution. Although Sony did not submit it for DxOMark testing, its image quality reveals excellent dynamic range and color depth, especially when shooting in RAW.

The A37 sports a 16.1-megapixel APS-C sensor (23.5 x 15.6 mm) with a slightly lower resolution (4912 x 3264). It achieved a notable DxOMark score of 75, with very good color depth (23.3 bits) and dynamic range (12.9 EV). Its maximum native ISO extends to 25600, promising usable low-light performance, though noise becomes noticeable above ISO 1600.

For detail retention and pixel-level sharpness, the QX1 holds a slight edge thanks to its larger pixel array and newer sensor design. That said, the practical difference between 16MP and 20MP across APS-C sensors is subtle unless performing large prints or heavy cropping.

In terms of dynamic range and color accuracy, both cameras produce pleasing, natural results, with the A37 benefiting from steady improvements in Sony’s Bionz X image processor line.

Overall, if pixel-peeping and detail fidelity are paramount, the QX1 nudges ahead, but the A37 remains competitive with richer high-ISO capabilities.

Autofocus Systems: A Contrasting Approach

Autofocus performance is a make-or-break factor for many photographers, so let's drill down.

The QX1 employs a contrast-detection autofocus system exclusively, with 25 focus points and face detection supported via the app. While contrast detection can be accurate, it is slower and less reliable for tracking moving subjects, lacking continuous AF or tracking AF modes.

In contrast, the SLT-A37 benefits from Sony’s translucent mirror technology, allowing phase-detection autofocus via 15 points (3 cross-type). This results in faster focus acquisition and continuous autofocus (AF-C) capability, making it more suitable for action and sports photography.

The A37 also features superior AF accuracy in low light due to phase-detection sensors.

For portraits or landscapes, the QX1’s AF is adequate though slower; however, wildlife and sports shooters will appreciate the responsive AF of the A37, which keeps subjects sharp even during bursts at 6 fps.

Build Quality and Weather Sealing: How Tough Are They?

Both cameras lack professional-level weather sealing or ruggedization.

The QX1 has a plastic build with minimal environmental protection. Given its lens-style design with no built-in grip or viewfinder, it’s not designed for harsh conditions.

The A37 offers a more robust polycarbonate body with a traditional DSLR style but also lacks dust or moisture sealing. The heavier build gives a sense of reliability but doesn’t invite heavy-duty outdoor use.

For rough weather or demanding environments, neither is ideal, but the A37 handles light outdoor conditions better, thanks to its built-in protection and comfortable ergonomic grip.

LCD Screen and Electronic Viewfinder: Framing and Toughness in the Field

Neither camera places a premium on screen resolution, but their user interfaces differ significantly.

The QX1’s lack of a physical screen means you’re tethered to your phone display for composing and reviewing images. This can be tricky in bright daylight or complex settings. By comparison, the A37 sports a 2.6-inch tilting screen, enabling flexible angles when shooting low or high, and a 1440-dot electronic viewfinder with full coverage and reasonable magnification, aiding precise framing.

For anyone who finds focusing through a physical EVF or LCD crucial, the A37 is definitively the better proposition.

Lens Ecosystem: Flexibility and Compatibility

Both cameras use APS-C sized sensors but differ fundamentally in lens mounts.

The QX1 uses the Sony E-mount, allowing access to Sony’s rapidly growing mirrorless lens ecosystem, complemented by adapters that extend support to other mounts including Canon EF lenses with autofocus.

The A37 uses the Sony A-mount (Minolta Alpha) system, with a mature but aging lineup of over 140 lenses available, including many third-party options.

While both mounts offer large lens selections, the E-mount's more modern optics and growing investment arguably make the QX1 more future-proof. However, the A37 supports older A-mount primes that certain photographers still prize for portraiture and macro work.

Burst Shooting and Buffer: Catching Fast Action

With burst shooting, the QX1 tops out at 4 frames per second, which can handle moderate action but isn’t optimal for sports or wildlife photography. Additionally, the buffer depth is limited, meaning long sequences will be interrupted.

The A37 offers faster 6 fps continuous shooting and a deeper buffer, making it far more responsive for capturing decisive moments in rapid sequences.

Video Capabilities: Beyond Stills

Video enthusiasts will find the A37 significantly more capable. It supports:

• Full HD 1080p recording at 60 fps for smooth footage
• Multiple encoding options (MPEG-4, AVCHD, H.264) for quality and flexibility
• External microphone input for better audio capture
• HDMI output

The QX1 records 1080p at 30 fps with MPEG-4 format but lacks microphone input, output connectors, and in-body stabilization, limiting creative or professional video uses.

For hybrid shooters who want a stills camera that doubles as a video device, the A37 is the clear winner.

Stabilization and Low-Light Handling

The A37 includes sensor-based image stabilization helping reduce blur from camera shake, which is notably missing in the QX1’s design. This feature is a tremendous advantage for handheld shooting in low light and longer focal lengths.

At ISO sensitivity, the QX1 maxes out at ISO 16,000, while the A37 reaches ISO 25,600, providing more leeway in challenging lighting conditions. Although noise performance at extreme ISOs is not stellar by today’s standards, the A37 maintains usable image quality better than the QX1 above ISO 3200.

Battery Life and Storage

Battery endurance is crucial on long shoots. Both cameras use the Sony NP-FW50 battery pack, a standard for many Sony APS-C models.

• The QX1 delivers approximately 440 shots per charge. However, wireless connectivity drains power faster than a traditional camera.
• The A37 is rated around 500 shots, benefiting from more efficient operation and fewer wireless demands.

The A37’s more comfortable grip and battery size help sustain longer field sessions without recharge.

Both cameras allow a single storage card slot, with the QX1 supporting microSD and Memory Stick Micro, while the A37 supports SD, SDHC, SDXC, and Memory Stick Pro Duo formats - favoring more robust and faster media types for continuous shooting and high-bitrate video.

Connectivity Features

The QX1 offers integrated Wi-Fi and NFC for seamless connection to smartphones for image transfer and remote control. It’s designed for an app-first experience, making social sharing easy.

The A37 supports Eye-Fi card connectivity but lacks modern Wi-Fi or NFC integrated into the body. This reflects its 2012 design focus before wireless connectivity became mainstream.

For quick social media posting, the QX1 has the edge. However, reliability and speed of connection vary depending on phone compatibility and app performance.
