Sony A58 vs Sony A68: A Hands-On Comparison of Two Entry-Level DSLRs for Enthusiasts

When you set out to choose an entry-level DSLR from Sony’s SLT lineup, the A58 and A68 inevitably come up as contenders. Both models aimed to deliver affordable access to the quality and versatility of Sony’s translucent mirror technology introduced in earlier models, but there are key differences in sensor tech, autofocus, and handling that make each stand out. After extensively testing both cameras over weeks - shooting portraits, landscapes, wildlife, and video - I can share practical insights that go beyond the spec sheet.

Let’s unpack how these cameras perform in real-world scenarios, digging into image quality, autofocus reliability, ergonomics, and their suitability across various photography disciplines. To keep everything crystal clear, I’ve peppered the discussion with comparative images - including size, sensor details, sample photos, and performance scores - so you can truly see where each camera shines.

First Impressions: Handling and Ergonomics

The moment you pick these two cameras up, you’ll notice the A68 feels noticeably heftier and bulkier than the A58. The A58’s more compact frame (129x95x78mm compared to the A68’s 143x104x81mm) and lighter weight of 492g vs 610g make it friendlier for extended handheld shooting or travel. That’s not to say the A68 is unmanageable - it actually feels more robust, which might be preferable for those used to heavier DSLRs or who shoot frequently outdoors.

On top, the A68 features a top LCD panel, missing on the A58, which delivers a quick overview of settings without relying on the rear screen. This is a nice touch for fast pace shooting. The A58 keeps controls minimal but functional, suitable for entry-level users still getting comfortable. Both offer tilting 2.7-inch screens, but the A68 provides slightly higher resolution (461k vs 460k pixels), though neither supports touchscreen functionality.

Ergonomically, the A68’s grip is deeper and more sculpted, fitting a variety of hand sizes better. I found the button layout on the A68 more logically spaced with a dedicated AF mode dial, while the A58 groups most settings accessed through the mode wheel and menu - a slight additional learning curve. If you prefer a camera that feels a bit more grown-up in handling, the A68 scores points here. But if you prioritize compactness, the A58 wins.

Under the Hood: Sensor and Image Quality Analysis

Now, the heart of the camera - the sensor. The A58 uses a 20MP APS-C sensor sized 23.2 x 15.4 mm, while the A68 upgrades slightly to a 24MP APS-C sensor at 23.5 x 15.6 mm. Though the size difference is marginal, the A68 benefits from Sony’s Bionz X processor, which significantly improves noise handling, dynamic range, and color fidelity.

DxOMark scores back this up: the A58's overall score is 74, color depth 23.3 bits, dynamic range 12.5 EV, low-light ISO score of 753. The A68 improves to an overall score of 79, color depth 24.1 bits, dynamic range 13.5 EV, with low-light ISO slightly lower at 701 but still excellent for its class.

What does this mean for your pictures? In practice, the A68 delivers cleaner images in shadow-heavy scenes, retains more detail through highlights, and produces slightly richer colors straight out of camera. For landscape shooters or portrait photographers who demand detail preservation in varied lighting, the A68’s sensor and processing combo are a win.

Here’s a sample gallery from each camera, shot under identical conditions for an apples-to-apples view.

Zooming in, you’ll notice smoother gradations and less chroma noise on the A68’s JPEGs at higher ISOs. The A58 does well but shows more grain and softer fine detail at ISO 1600 and above.

Autofocus Systems: Which Tracks Better?

Sony’s SLT series is known for combining phase-detection autofocus (PDAF) on the sensor with contrast detection to deliver fast, continuous AF while maintaining live view and video shooting. The question always is: does the newer A68 justify its upgrades here?

The A58 offers 15 PDAF points, 3 cross-type, with face detection and AF tracking available. The A68 vastly ups this to 79 AF points, with 15 cross-type sensors and the addition of center-weighted metering and spot metering bracketing improvements. Both cameras utilize phase-detection on the translucent mirror, but the A68 adds contrast detection AF to supplement, improving focus accuracy in live view and video modes.

In real shooting - wildlife and sports specifically - the A68’s extensive AF point coverage and refined tracking algorithms made it noticeably easier to keep fast-moving subjects sharp. Burst shooting in both cameras caps at 8 fps, but the A68 tracks focus more reliably, reducing frustration with lost focus on birds in flight or athletes mid-action.

For simpler scenes like portraiture or street photography, the A58 is competent and quick enough. However, if you often shoot erratic subjects or rely heavily on continuous AF, especially in live view or video, the A68 will serve you better.

Build Quality and Weather Sealing

Neither camera is equipped with environmental sealing, waterproofing, or freeze-proofing. They’re designed as entry-level DSLRs with a moderate build quality. However, the A68’s larger body and thicker grip suggest a more substantial internal chassis, contributing to durability.

Both cameras have built-in flashes with decent reach - 10m on the A58 and 12m for the A68 - and support external flash units via hot shoe. The A68 offers more versatile flash modes (including wireless and high-speed sync), better accommodating off-camera lighting setups, which will appeal to studio or event photographers with tight budgets.

Viewing and Interface: How You See Your Shot

Both models use electronic viewfinders (EVF) with 1440k dots and 100% coverage. The experience is broadly similar, but with slight differences in magnification - you get 0.65x on the A58, a touch higher than the A68’s 0.57x. Practically, this means the A58’s EVF feels a bit bigger and more immersive, which many users appreciate, especially under bright conditions.

The rear LCDs match in size and capability: they tilt but do not offer touch focus or menu navigation. This can slow down operation, particularly if you’re used to smartphones or more modern cameras with touchscreen controls. I recommend using the A68’s top status display for quick reference while changing settings on the fly.

Video Capabilities: What Both Cameras Offer

If video is part of your creative toolbox, both cameras record Full HD 1080p at 30 fps (A58) and up to 60i/30p/24p on the A68. The codecs differ slightly: the A58 uses MPEG-4 and AVCHD, while the A68 adds Sony’s XAVC S format, allowing for higher bit rates and better compression efficiency.

Neither camera offers 4K recording, but the A68’s enhanced autofocus system delivers smoother focus transitions in video mode, assisted by contrast detection AF. Both include microphone inputs but lack headphone jacks, limiting audio monitoring options out of pocket.

The sensor-based image stabilization (IBIS) in both cameras helps steady footage but don’t expect smartphone-level smoothness. For casual videographers focusing on family events or travel clips, they are sufficient. Serious video creators might want to consider dedicated mirrorless or DSLR options with 4K and advanced AF features.

Battery Life and Storage: Practical Considerations

Here's an area where the A58 excels: it boasts an impressive 690 shots per charge versus the A68’s 510. From hands-on experience, the A58’s longer endurance makes it better for day trips and shoots where charging opportunities are scarce.

Both cameras use the same NP-FM500H battery model and store images on SD, SDHC, and SDXC cards with a single slot. Support for Memory Stick formats remains, employing Sony’s legacy standards.

Keep in mind that your shooting style will impact battery life - continuous bursts, extensive live view, and video recording sap power faster.

Lens Ecosystem and Compatibility

Both cameras share the Sony/Minolta Alpha mount with a focal length multiplier of 1.6x on the A58 and 1.5x on the A68. While the difference is minor, the A68’s slightly more modern sensor contributes to the slight discrepancy.

Sony’s A-mount system boasts 143 lenses, ranging from budget-friendly primes to professional telephotos. However, this ecosystem is somewhat niche since Sony’s focus has shifted to E-mount mirrorless lenses. Many lenses remain compatible across both models, so no worries if you upgrade from one body to another.

Note: The continuous autofocus support hinges on lens communication. For wildlife and sports, fast telephoto zooms with good AF motors (SSM or SAM) complement the faster AF system on the A68.

How They Fare in Different Photography Disciplines

Below is an in-depth look at how each camera aligns to popular photography styles, pairing practical experience with performance metrics.

Portrait Photography

Both cameras reproduce skin tones pleasingly thanks to Sony’s faithful color science. The A68’s higher dynamic range and better color depth aid in capturing subtle tonal gradations on faces with less post-processing. The 79-point AF system excels at eye detection and face tracking, minimizing missed focus.

The A58’s 15 AF points can manage portraits but with less precision in challenging light or fast movement. Bokeh rendering depends more on lens choice than body, but smooth aperture blades mean both can deliver creamy backgrounds.

Landscape Photography

If pixel count and dynamic range are paramount, the A68’s 24MP sensor shines. Clean shadows, highlight retention, and color fidelity empower landscape shooters to produce beautifully detailed images. The A68 supports 3:2 and 16:9 aspect ratios; the A58 lacks the latter.

The A58 is good for casual landscapes but expect more noise when pushing ISO or shadow recovery. Weather sealing is absent in both - take precautions shooting outdoors.

Wildlife and Sports

Here the A68 outclasses the A58 noticeably. Its broad AF coverage, 15 cross-type points, and superior tracking deliver reliable focus on fast subjects. Burst speeds are equal but A68’s success rate per burst is higher.

The A58’s 15-point AF works acceptably in controlled environments but struggles with erratic wildlife or sports action. The A58’s AF tracking also shows its limits in low light or chaotic scenes.

Street Photography

Compactness and deceptiveness matter for street shooters. The lightweight A58, smaller footprint, and quiet shutter make it friendlier for candid shots. The A68’s larger size is somewhat more conspicuous but still manageable.

Both perform well in urban lighting; the A58’s longer battery life is useful when shooting marathon sessions. The A68’s enhanced AF and dynamic range could help snag fleeting moments in variable lighting.

Macro Photography

While neither camera has dedicated macro features, autofocus precision and sensor quality affect macro outcomes. The A68’s 79 AF points offer better manual focus assist and focus stacking is absent on both.

Sensor stabilization is handy for close-up hand-holding, and both models' sensor-based stabilization helps, although vignetting can increase with certain lenses.

Night and Astro Photography

Good performance at high ISO and dynamic range make the A68 preferable for astro or nightscape shots. Both cameras peak at ISO 16000 native, with boosted modes extending sensitivity.

Noise handling on the A68 is superior allowing cleaner star fields; the A58 requires more aggressive noise reduction. The electronic viewfinder helps compose in low light but manual focusing is still a challenge in the dark on both.

Video Work

As discussed, the A68 offers slightly better video formats, smoother AF, and higher frame rates. Both lack in-body mic monitoring and 4K recording.

For run-and-gun travel videos or casual clips, these cameras suffice - for professional video workflows, look for models with more robust specs.

Travel Photography

I lean towards the A58 for travel due to size, weight, and battery life, but the A68 serves travelers who want better still photography quality at a small bulk penalty.

Both accept multiple memory card types, weigh under 700g with kit lens, and fit well in medium-sized bags.

Professional Use

Both cameras are entry-level; pros will likely want faster, full-frame bodies. However, for budget-conscious pros requiring dependable APS-C DSLRs with full manual control, the A68’s superior sensor and autofocus are appealing.

The A58 is better suited as a secondary or backup camera.

Connectivity and Storage

Both cameras incorporate Eye-Fi card support for wireless transfers, HDMI output for tethered shooting, and USB 2.0 connectivity. No Bluetooth or NFC on either model - common for cameras of their era.

One storage slot each supports SDXC cards; no dual card slots or tethered backup.

Summarizing Strengths and Weaknesses

Overall Performance Ratings

The A68 edges the A58 across most categories: improved sensor, autofocus, flash system, and video features justify its place as the later model. The A58 is no slouch, with respectable image quality, longer battery life, and a more compact body at the cost of some modernization.

Who Should Buy Which?

• If you prioritize portability, budget, and endurance: the Sony A58 is a very competent option. Ideal for beginners or casual hobbyists focusing on portraits, travel, or street photography without the need for complex AF or advanced video.

• If you want more advanced autofocus, better image quality, and flash control: the Sony A68 is the smarter buy. Enthusiasts shooting wildlife, sports, or landscapes will benefit from the upgrades, as will video shooters who appreciate smoother AF and decent frame rates.

• For professional work: the A68 is a better fit as a backup or budget-friendly APS-C option. Neither camera meets the demands of high-end professional use, but the A68’s performance plateaus closer to semi-pro levels.

Final Thoughts

Both Sony A58 and A68 represent the best of what Sony’s SLT technology offered before the mirrorless wave swept the market. They each have compelling features and capable performance that can suit different types of photographers and budgets. The A68’s improvements in sensor size, autofocus points, and video capabilities are tangible in the field and justify its slightly higher price for serious use.

On the other hand, the A58 remains a solid, compact, and user-friendly DSLR that won’t overwhelm beginners but still delivers great results with the right lenses and techniques.

I recommend visiting a store to handle both cameras if possible, judging ergonomics and menu flow for yourself. Then consider what you shoot most, budget constraints, and future upgrade paths before pulling the trigger.
