When examining two cameras nearly a decade apart, it’s fascinating to witness how far imaging technology has progressed - especially within the same brand family. I’ve had the pleasure of extensively testing both the Sony Alpha DSLR-A290, an entry-level DSLR launched in 2010, and the Sony Alpha a6400, an advanced mirrorless model released almost nine years later. They represent two very different design philosophies, technological eras, and user expectations.

In this deep-dive comparison, I’ll guide you through the strengths, weaknesses, and practical performance of both cameras across major photographic genres and real-world usage scenarios. My hands-on experience with thousands of cameras allows me to interpret specifications through the lens of actual shooting conditions, helping you decide which is the better fit for your creative aspirations and budget.

A Tale of Two Systems: DSLR Meets Mirrorless in Form and Function

Here’s a side-by-side of the Sony A290 and Sony A6400 that instantly reveals contrasts in body size and ergonomics.

At first glance, these cameras couldn’t appear more different. The A290 boasts a compact DSLR body with a somewhat traditional heft at 549g and dimensions of 128 x 97 x 86mm. Ergonomically, it caters to shooters preferring a classic SLR shape - larger grip, optical viewfinder, and physical dials.

The a6400, by contrast, is a sleek, lightweight mirrorless camera weighing just 403g with markedly smaller dimensions - 120 x 67 x 50mm. Its rangefinder-style design emphasizes portability and modernity, with a tilting touchscreen and electronic viewfinder.

From my experience, the A290’s DSLR size can feel reassuringly substantial in hand, especially with large lenses, making it favorable for those who appreciate tactile controls and traditional camera handling. The a6400 appeals to travelers and street photographers craving a discreet, nimble setup without sacrificing advanced features.

The Engine Under the Hood: Sensor, Processor, and Image Quality

Sensor specs play a huge role - the A290’s CCD vs. the a6400’s CMOS reveals distinct technology eras.

The A290 employs a 14MP APS-C CCD sensor, coupled with Sony’s older Bionz processor. Despite the lower megapixel count and dated sensor tech, CCDs have historically delivered pleasing color rendition and smooth gradient transitions, which many portrait photographers might appreciate.

The a6400 upgrades significantly with a 24MP APS-C CMOS sensor and the powerful Bionz X processor. The higher resolution translates into more detail, while the CMOS’s superior noise handling and dynamic range shine in challenging lighting.

Looking deeper into image quality through DxOMark scores - the A290 obtains an overall 66, with color depth at 22.6 bits and dynamic range roughly 11.5 EV stops. The a6400 leaps ahead with a score of 83, a color depth of 24 bits, and dynamic range of 13.6 EV. These technical advantages confirm my field experiences: the a6400 produces files with richer tonality, better highlight retention, and cleaner shadows.

In landscape photography, this means the a6400 captures wider exposure latitude, rendering subtle sky textures and shadow details flawlessly. The A290 holds up well for casual shooting, but you’ll encounter more noise at higher ISOs.

Controls and Usability: Navigating Your Camera

The A290 offers a modest 2.7-inch fixed LCD with 230,000 dots and no live view. It relies on an optical pentamirror viewfinder with 95% frame coverage and 0.55x magnification. While adequate for composition, I frequently found the viewfinder limiting for critical framing, especially in fast action or precise focus tasks.

The a6400’s 3-inch tilting touchscreen with 922,000 dots speaks directly to modern demand for flexibility - whether you’re shooting selfies, low angles, or recording video. Its 2.36M dot OLED electronic viewfinder provides 100% coverage and 0.7x magnification, offering a crystal-clear, real-time preview of exposure, white balance, and depth of field effects. This EVF is a game-changer in both studio and outdoor environments.

Autofocus: Eye Detection, Speed, and Tracking

One of the most striking differences lies in autofocus technology and performance. The A290’s phase-detection AF system has just 9 focus points and lacks continuous tracking or eye detection. It works reliably under good light but can be slow and prone to hunting in low contrast conditions.

Conversely, the a6400 boasts 425 phase-detection AF points spread widely across the frame, with advanced Real-time Eye AF for humans and animals - a feature that I repeatedly tested in portrait and wildlife scenarios with outstanding precision. Continuous shooting with AF tracking reaches 11fps on the a6400, whereas the A290 maxes out at 3fps.

This puts the a6400 head and shoulders above for sports, wildlife, and any scenario demanding fast, confident focus acquisition and tracking. The A290, while decent for still life or casual portraits, struggles in situations where subjects are moving unpredictably.

Performance Across Photography Genres

Let’s explore how each camera handles specialized real-world photographic disciplines.

Portrait Photography: Skin Tones and Bokeh

Both cameras produce pleasing skin tones owing to Sony’s color science, but the a6400’s larger native ISO range up to 32,000 (expandable to 102,400) enables shooting in indoor or evening settings without heavy noise. The A290 maxes out at ISO 3200, and images degrade noticeably beyond ISO 800.

Bokeh quality depends primarily on lens selection, but the a6400’s superior autofocus and higher resolution help isolate subjects sharply with smooth background defocus using fast E-mount lenses. Eye-detection AF is invaluable for pinpoint sharpness on eyes - an essential feature for professional portraits that the A290 simply lacks.

Landscape Photography: Dynamic Range and Durability

The a6400 impresses with 13.6 EV dynamic range - meaning better detail in gradients, skies, and shadows. The A290’s 11.5 EV is respectable but more limited.

Weather sealing is present on the a6400 body (dust and moisture resistant), an asset for landscape shooters often in unpredictable environments. The A290 lacks any environmental sealing, which constrains rough-weather use.

Wildlife and Sports: Autofocus and Speed

In wildlife and sports, autofocus responsiveness and frame rate define success. The a6400’s 11fps continuous burst with full AF-tracking outperforms the A290’s 3fps fixed focus burst capability. From my testing, the a6400 nails sharply focused frames on fast-moving subjects like birds in flight or athletes, whereas the A290 is better suited to still or slow subjects.

Street Photography: Discretion and Portability

Here, the a6400 shines due to compact size, lightweight body, and silent electronic shutter (absent in the A290). Its tilting touchscreen also aids low-angle snap candid shots, while the A290’s bulkier DSLR design and noisier shutter make it less stealthy.

Macro Photography: Magnification and Stability

Neither camera offers built-in stabilization, but the A290 has sensor-based image stabilization, which can help slightly with handheld macro shots. The a6400 depends on lens stabilization, but benefits from excellent manual focus magnification aids on-screen. Precision focusing is much easier on the a6400’s electronic viewfinder with peaking and magnification features.

Night and Astrophotography: High ISO and Exposure Control

The a6400’s expanded ISO range and stronger noise handling provide clearer images at night. The camera supports manual bulb exposure and customizable interval shooting, beneficial for astrophotographers. The A290 falls short in high ISO noise performance and lacks advanced long exposure modes.

Video Capabilities

Video technology is another gulf between these cameras. The A290 offers none, restricted to still shooting only.

The a6400 excels with 4K UHD video at 30p, Full HD at higher frame rates, and offers clean HDMI output - features that meet many content creators’ needs. It supports XAVC S codec, enabling superior compression and detail retention. A microphone input allows for quality audio, which serious videographers will appreciate.

Though lacking headphone monitoring, the a6400 remains a highly capable hybrid shooter for both photos and cinematic video, leaving the A290 in the dust on this front.

Build Quality, Battery Life, and Storage

The A290’s older battery (NP-FH50) delivers about 290 shots per charge, adequate for casual use, but the a6400’s NP-FW50 battery extends life to 410+ shots thanks to efficiency gains and mirrorless design.

Both cameras rely on single SD card slots, with the a6400 supporting faster UHS-I cards and more versatile storage options (SDXC).

Build-wise, the a6400’s weather resistance and robust magnesium alloy body inspire confidence in demanding shooting scenarios, whereas the A290’s polycarbonate shell feels more consumer-grade.
