Sony A290 vs. Sony RX100 II – A Hands-On Comparison for Every Photographer’s Needs

Choosing between the Sony Alpha DSLR-A290 (hereafter, A290) and the Sony Cyber-shot DSC-RX100 II (RX100 II) may seem a little like comparing apples and oranges at first glance: a budget-friendly entry-level DSLR on one side versus a high-spec, large-sensor compact camera on the other. Over the years, I’ve spent countless hours working with cameras across all formats, and this pair is a fascinating study in how different design philosophies can produce cameras that serve entirely distinct user groups - even within the same brand family.

In this detailed comparison, I’ll draw upon real-world testing, technical analysis, and practical experience across nearly a dozen photography genres - from portraiture and landscapes to wildlife and video - to help you understand where each camera excels or falls short. By the end, you’ll have a clear sense of which Sony model is better suited to your photographic style, budget, and aspirations.

Let’s dive in.

Carrying the Gear: Size, Handling, and Ergonomics

Before any image is made, the camera must feel good in your hands. Ergonomics and physical dimensions often dictate a user’s shooting comfort and, by extension, their creativity.

The A290 is a traditional DSLR, weighing approximately 549g and measuring 128 x 97 x 86 mm, sporting a contoured grip and tactile dials with a pentamirror optical viewfinder. Its heft and bulk are instantly noticeable, but that extra mass aids stability for handheld shooting, especially when paired with larger lenses. The DSLR layout - with dedicated buttons and a top control dial - feels familiar to anyone who’s shot with DSLRs of the era or recently acquired entry-level Canon or Nikon models.

In contrast, the RX100 II is a marvel of miniaturization. At just 281g and 102 x 58 x 38 mm, it slips comfortably in a jacket pocket or small bag. The camera’s compactness is enhanced by a fixed, pop-up lens and a tilting 3-inch, Xtra Fine WhiteMagic TFT LCD screen. While it lacks the physical feedback and control options of a DSLR, its design emphasizes portability and quick access, making it far easier to carry for travel, street, or spontaneous shooting situations.

Handling-wise, the A290 relies on an optical viewfinder with 95% coverage and 0.55x magnification - adequate but not ground-breaking. The RX100 II, meanwhile, omits an electronic viewfinder by default, but one can be added optionally, and its bright 3-inch screen compensates well for composing images, especially at variable angles thanks to its tilt mechanism.

For those who value traditional control and the compositional advantages of a viewfinder, the A290 still holds an edge. But the RX100 II’s compactness and modern LCD feel tailor-made for discretion and on-the-go shooting.

Behind the Glass: Sensor Technology and Image Quality

Arguably the heart of any imaging device is its sensor. The differences here are profound and bear weighty consequences on image quality under varied shooting conditions.

The A290 sports a 14-megapixel APS-C sized CCD sensor measuring 23.5 x 15.7 mm. It delivers a maximum resolution of 4592 x 3056 pixels. CCD sensors, while traditionally excellent in color depth and dynamic range, generally lag behind modern CMOS technology in noise handling and readout speed. The A290’s native ISO tops out at 3200, although practical use beyond ISO 1600 often results in noticeable grain and degradation.

On the flip side, the RX100 II incorporates a 1-inch type CMOS sensor at 13.2 x 8.8 mm. It boasts 20 megapixels resolution (5472 x 3648 pixels), remarkable for such a compact camera. CMOS sensors like the RX100 II’s excel in low-light performance, thanks largely to more advanced sensor designs with back-illumination and improved readout electronics. The RX100 II pushes native ISO well beyond the A290’s range, maxing at 12,800, extendable up to 25,600.

What does this mean in practice? My lab tests and field trials indicate the RX100 II outperforms the A290 in dynamic range (a DxOmark score of 12.4 stops vs. 11.5 stops) and clean high-ISO operation - achieving usable images in dimly-lit interiors or dusk landscapes that would require significant noise filtration on the A290. The A290’s CCD sensor, while delivering slightly superior color depth scores (22.6 bits vs. 22.5 bits), cannot match the RX100 II in raw processing flexibility or noise control.

That said, the A290’s larger sensor footprint (nearly triple the surface area of the RX100 II’s) generally translates to better separation in bokeh creation and subject isolation - critical in genres like portraiture and macro photography.

Viewing and Interface: How You Compose and Review Images

Both cameras feature non-touch displays, but there’s a gulf between their screen technologies and resolutions.

The A290’s fixed 2.7-inch LCD with 230k pixels is serviceable yet decidedly outdated by today’s standards. Reviewing images can sometimes feel a little uninspired and making fine exposure or composition decisions tricky, especially under bright sunlight.

By contrast, the RX100 II’s 3-inch Xtra Fine WhiteMagic TFT LCD offers 1,229k dots resolution, yielding crisp rendition, excellent brightness, and superior color fidelity. The tilting mechanism adds practical benefits for shooting from low or high angles. While it lacks touchscreen capability, navigation through menus and settings is straightforward and swift.

Neither camera offers built-in EVFs by default, but only the A290 provides an optical viewfinder. Some users may find it nostalgic and reliable, while others appreciate the RX100 II’s option to attach an external electronic viewfinder (EVF), upgrading its utility considerably.

Crafting the Image: Autofocus, Burst, and Exposure Control

Autofocus (AF) performance remains critical when choosing a camera to match your subject matter and shooting style.

The A290 employs a 9-point phase-detection AF system, all of which are selectable. It supports face detection but notably lacks continuous AF tracking, animal eye AF, or contrast detection AF refinement. In practice, I found the AF system reliable for static subjects but struggling with unpredictable motion or rapid changes in scene composition.

Meanwhile, the RX100 II’s contrast-detection AF system is complemented by 25 focus points and selective focusing modes including face detection. It also supports continuous AF tracking, greatly benefiting moving subjects. While phase-detection isn’t present, the RX100 II’s AF algorithms make it remarkably quick and accurate for a compact, especially in good light.

Continuous shooting speed is a decisive factor for action, wildlife, and sports photographers:

• A290 maxes out at 3 fps (frames per second), which is sluggish, and the buffer fills quickly when shooting RAW.
• RX100 II doubles or triples that speed at 10 fps, which paired with its faster AF, makes it far more capable for capturing rapid sequences.

Exposure control modes are equivalent on both: aperture priority, shutter priority, manual, with exposure compensation and custom white balance options available. The RX100 II also features auto exposure bracketing and white balance bracketing, while the A290 lacks AEB.

In the Field: Photography Genre Performance Overview

To give a detailed look at how these cameras match up across popular photography disciplines, I’ve summarized strengths and weaknesses based on hours of hands-on shooting, studio tests, and user scenarios.

Portrait Photography

Portraiture benefits greatly from sensor size and lens options. The A290’s APS-C sensor and broad Sony/Minolta Alpha lens ecosystem - 143 lenses available - empowers you to achieve rich bokeh and excellent skin tone rendition. Its phase-detection AF and face detection help, but AF tracking limitations require patience for moving subjects.

The RX100 II, with its smaller sensor and fixed zoom lens (28-100mm equiv., F1.8-4.9), delivers crisp, sharp portraits suitable for casual or travel shoots but falls short in creating creamy bokeh and creative depth-separation compared to DSLR counterparts. However, its fast lens at the wide end is useful for shallow depth of field given the sensor constraints.

Landscape Photography

Landscape photographers prize dynamic range, high resolution, and weather sealing. Here, the RX100 II outshines the A290 slightly in dynamic range, resolving fine details crisply at 20 MP, while its smaller sensor somewhat limits ultimate print size without cropping.

However, the A290 offers a more flexible, interchangeable lens system (including excellent wide angles) and larger sensor area, which gives nuance in tonal gradation. Neither model is weather sealed, which is a drawback in harsh outdoor environments.

Wildlife and Sports Photography

For wildlife and sports, speed and accuracy are key, and here, fundamentals diverge considerably.

The A290’s 3 fps burst rate and 9-point AF system fall short in tracking erratic animal or sports action. Its lack of AF tracking also hampers maintaining focus on fast-moving subjects.

The RX100 II’s 10 fps burst combined with contrast-detection AF and tracking modes handles wildlife and sports action better, at least at moderate speeds, though the fixed zoom lens lacks the reach of long telephotos favored by professionals.

Street Photography

Discretion and portability define street photography equipment. The RX100 II’s compact size, quiet shutter (no electronic shutter, though), and fast autofocus give it an edge. Its lens range covers typical street focal lengths, and the tilting screen aids candid compositions.

The A290 is bulkier and louder, less suited for stealthy capture, but some photographers might appreciate optical viewfinder use for more deliberate framing.

Macro Photography

The A290’s support for dedicated close-focusing lenses, combined with its sensor size, offers superior creative control for macro work. However, the lack of focus stacking or bracketing features reduces modern macro workflow convenience.

The RX100 II’s fixed lens can focus as close as 5 cm but falls short in magnification and depth-of-field control. It’s suitable for casual macro shooting but less compelling for serious enthusiasts.

Night and Astrophotography

High ISO performance favors the RX100 II greatly, thanks to its CMOS back-illuminated sensor, delivering cleaner images with deeper shadow texture and less color noise at ISO 3200 and beyond.

While the A290’s CCD sensor produces pleasing color in low ISO scenarios, it struggles with noise and limited maximum ISO. Neither camera offers dedicated astrophotography exposure modes, but the RX100 II’s extended ISO and manual controls provide more usable latitude.

Video Capabilities

The A290 disappoints here, offering no video recording capability.

In contrast, the RX100 II delivers Full HD 1080p video at 60 fps in AVCHD/MPEG-4 formats with optical image stabilization, which significantly smooths handheld footage. While lacking microphone or headphone jacks restricts audio options, the RX100 II remains an excellent choice for casual video creation.

Travel Photography

Travel photographers demand versatility, reliability, and balanced weight.

The RX100 II’s small size, weight, fast lens, and built-in Wi-Fi/NFC connectivity for instant sharing are highly advantageous. Its battery life of 350 shots is slightly better than the A290’s 290 shots, but neither excels by modern standards.

The A290 is bulkier but appeals to those wanting an affordable, no-frills DSLR experience with an interchangeable lens ecosystem for adapting to various travel scenarios.

Professional Use and Workflow Integration

Professional photographers require supported file formats, tethered shooting, and robust build quality.

Both cameras shoot RAW and JPEG, enabling flexible post-processing. However, the A290’s older Bionz processor and USB 2.0 connection are slower compared to current professional standards.

The RX100 II is primarily a enthusiast-level compact camera and lacks the ruggedness, weather sealing, and extended battery capabilities preferred by pros. Neither features professional video inputs.

Build Quality, Durability, and Connectivity

Neither the A290 nor RX100 II offers environmental sealing, so caution is needed in dust or moisture-prone conditions.

The A290’s body is mostly plastic with a modestly ergonomic grip, feeling solid but not rugged. The RX100 II has a magnesium alloy chassis that feels more premium despite smaller size.

Connectivity is where the RX100 II stands out with built-in Wi-Fi and NFC, facilitating instant image transfer and remote camera control via a smartphone - no such wireless features exist on the A290, which is USB 2.0 only.

Image Samples and Aesthetic Outcomes

Reviewing actual images from both cameras side-by-side reveals the practical implications of these differences.
