Olympus Stylus 7040 vs Sony SLT-A68: A Hands-on Comparative Review for Serious Photographers and Enthusiasts

Choosing a camera often feels like balancing art with science - between the tactile joy of the hardware and the technical precision of image capture. I’ve spent countless hours testing cameras across genres and skill levels, and today I’m placing the Olympus Stylus 7040 compact and the Sony SLT-A68 entry-level DSLR head-to-head. Two very different cameras, designed with distinct users in mind - but their features and real-world performance make for an interesting comparison that goes well beyond specs sheets.

Whether you’re a casual shooter, a specialist in wildlife or portrait photography, or a hybrid video/photo enthusiast, this in-depth comparison will help you understand the practical impact of their strengths and limitations. Let’s unpack everything from sensor tech and autofocus performance to handling and shooting versatility - and see which camera fits your photographic ambitions best.

Getting a Feel for the Body – Size and Ergonomics That Matter

What’s often underestimated is how much a camera’s physical presence affects your shooting experience. You want something that feels intuitive in hand, especially during long shoots.

Starting with the Olympus 7040, this is a compact point-and-shoot, tiny and pocketable. Its dimensions (95x56x26mm) and featherweight 144 grams make it incredibly portable, perfect for travel or street photography when discretion and mobility are vital. Holding it, you sense a straightforward, no-frills design - almost like a digital snapshot camera from the 2010 era. It opts for a fixed lens with a 28-196mm equivalent zoom, useful for everything from wide-angle shots to telephoto reach without swapping glass.

On the flip side, the Sony A68 is unmistakably a DSLR - 143x104x81mm and 610 grams. It’s not bulky by professional standards but clearly built for a more involved shooting style, complete with its solid handgrip and well-spaced buttons. The heft offers stability for telephoto work and longer sessions, and you’ll benefit from the sophisticated ergonomics typical of SLR-style cameras.

If you're someone who needs a grab-and-go device for casual shooting or traveling light, the Olympus’s compact footprint and simplicity are compelling. But if you crave control, prolonged use comfort, and perhaps heavier lenses, the Sony’s DSLR body gives you a tangible advantage.

Top-Down: Controls and Handling Comparisons

Moving deeper into the interface, let’s talk about control layout and tactile feedback - things that might not leap off spec sheets, but govern your daily shooting workflow.

The Olympus 7040 has a minimalistic control deck. Its top is neat, featuring a shutter button, zoom toggle, and a small mode dial. It lacks any customizable buttons or dedicated exposure controls like aperture or shutter priority modes. This simplification reflects its focus on point-and-shoot ease rather than manual finesse.

Compare that to the Sony A68, sporting a much more advanced layout visible in its top view. It includes the expected mode dial with all manual and semi-manual modes, dedicated ISO, drive mode, and exposure compensation buttons. There are function buttons that you can tailor, and the shutter release placement is ergonomic for rapid shooting. Its electronic viewfinder and tilting screen further enhance compositional flexibility.

If hands-on control and quick-access settings matter to you - perhaps for fast-changing conditions or for honing creative specifics - the Sony provides a richer tactile experience. The Olympus, meanwhile, is more about quick snaps with little fuss.

Sensor and Image Quality: The Heart of the Matter

This is where the story diverges sharply: sensor technology and imaging potential.

Olympus 7040 features a 1/2.3" CCD sensor (6.08x4.56mm), with 14 megapixels. Back in 2010, CCD sensors were common in compact cameras and often produced vibrant images with excellent color rendition for snapshots. However, the sensor’s small size limits dynamic range and low-light performance. The maximum native ISO is 1600, but noise becomes evident past ISO 400. Despite having sensor-shift stabilization - which is great for handheld shots - the fixed lens and small sensor combination inherently restricts sharpness and depth of field control.

In contrast, the Sony A68 employs a 23.5x15.6mm APS-C CMOS sensor, 24 megapixels strong. This sensor size is nearly 13 times larger in surface area than the Olympus’s CCD, inherently offering superior image quality, great dynamic range, and low noise at high ISOs up to 25600. I’ve evaluated its performance extending into low-light and shadow-heavy scenes, where it consistently pulls out detail without mottling. Combined with Sony’s Bionz X processor, images display excellent color fidelity and gradation.

For enthusiasts or professionals who need image quality suitable for large prints, cropping, and demanding lighting, the Sony A68’s sensor and processing pipeline deliver a noticeable edge. The Olympus will satisfy casual usage and situations where portability beats resolution.

Viewing and Composition: Screen and Viewfinder Features

Viewing your subject clearly and comfortably is key when framing shots or reviewing images.

The Olympus’s 3.0-inch fixed LCD screen has a modest 230k-dot resolution - enough to check framing on the fly outdoors, though it lacks sharpness and touchscreen interactivity. There’s no electronic viewfinder, meaning you’re relying fully on the back LCD.

The Sony A68, meanwhile, sports a 2.7-inch tilting LCD panel with 461k-dot resolution, nearly double the pixel density, allowing precise focusing confirmation. More importantly, it includes a 1440k-dot electronic viewfinder with 100% coverage, 0.57x magnification, and real-time preview of exposure, white balance, and focus. This makes a huge difference in bright light or for critical composition.

Ultimately, if you’re working in varied light and need a reliable framing tool, the Sony’s EVF and articulating screen won’t disappoint. The Olympus is decent for casual use but clearly less versatile.

Autofocus Systems: Speed and Accuracy in Action

AF defines success rates for fast-moving subjects and ease of use in general shooting.

The Olympus 7040’s autofocus relies on contrast detection only, with a multi-area function but no face or eye detection. The single continuous shooting speed is a very leisurely 1 fps. It does have sensor-shift stabilization to help with hand shake, but AF-wise, its performance is basic and more suited to static scenes or relaxed shooting.

The Sony A68 steps it up with a hybrid system combining phase detection and contrast detection autofocus. It provides 79 focus points, 15 cross-type, enabling accurate focusing in challenging conditions. It offers face detection, eye detection, and supports continuous autofocus with subject tracking at a brisk 8 fps burst rate, a boon for action or wildlife photography.

This difference is marked in real-world shooting: shooting birds in flight or sports events is simply more reliable and smoother on the Sony - with snappy acquisition and tracking even under difficult light.

Lens Ecosystem and Flexibility

One of the biggest advantages of the Sony A68 is its compatibility with Sony Alpha / Minolta A-mount lenses. There are over 140 native lenses ranging from fast primes to ultra-telephoto zooms, macro lenses, and specialty optics. This lens ecosystem supports photographers in virtually every genre and shooting style. Plus, adapters can expand this further.

The Olympus 7040, being a fixed-lens compact, limits you to the built-in 28-196mm f/3.0-5.9 zoom. While this covers a versatile zoom range, you cannot change lenses or add optical accessories. It also lacks manual focus control, which curtails creative control.

If your photography aspirations include varied focal lengths or specialized glass, the Sony offers a clear pathway, whereas the Olympus is locked into its built-in zoom’s compromises.

Handling Specialized Genres: How Each Camera Performs

Now I want to dig into real-world use cases across photography disciplines, bridging specifications with practical outcomes.

Portrait Photography

Sony’s larger APS-C sensor generates shallower depth of field, enabling creamy bokeh and subject separation - a key aspect of pleasing portraits. Its face and eye detection autofocus contribute to sharp captures, even in dynamic scenes. Combined with quality fast primes from Sony’s lens catalog, portrait results are refined and professional.

The Olympus’s smaller sensor and slower lens aperture range limit bokeh effects and skin tone nuance, often resulting in flatter images. But for casual portraits with adequate light, its image stabilization helps produce sharp shots handheld.

Landscape Photography

Dynamic range and resolution are crucial here. The Sony’s 24MP sensor, with an expansive dynamic range of about 13.5 EV, allows capturing detail from shadows through bright skies. I found its image quality excellent for landscape prints and wide aspect ratios (3:2 or 16:9). The camera’s build, while not weather sealed, is sturdy enough for outdoor work with care.

The Olympus 7040’s compactness is appealing for strolls in nature, but the limited sensor area and max ISO 1600 mean noise and detail fall-off under challenging lighting. Its 14MP resolution at 4:3 aspect ratio can hamper wide cropping, and lack of environmental sealing restricts rugged use.

Wildlife & Sports Photography

Sony’s AF speed, tracking accuracy, and 8 fps burst mode are huge assets here. Coupled with telephoto A-mount lenses, it excels in capturing fast, unpredictable movement. Its higher native ISO ceiling aids in early dawn or dusk conditions common to wildlife photography.

Olympus’s slow continuous shooting and contrast AF limit its effectiveness for action work. Its zoom range is helpful, but autofocus lag and low burst speed make it less useful beyond casual bird photography.

Street and Travel Photography

The Olympus wins for compactness and unobtrusiveness, crucial for candid street shots. Its lightweight form invites spontaneous shooting and fits easily in a coat pocket. Battery life isn’t specified, but point-and-shoot compacts typically offer a day of moderate use.

The Sony, bulkier and heavier, might hamper mobility during travel, but its versatility and superior image quality can make it worthwhile if you prioritize creative control over body size. The battery life of 510 shots per charge is solid for long days outdoors.

Macro Photography

Both cameras offer macro focusing, but the Olympus specifies a super close 2cm focus range, which is impressive for a compact. However, lacking manual focus adjustment and with a smaller sensor, its depth of field control and sharpness for fine detail is limited.

The Sony’s lens options include dedicated macro primes with excellent focusing precision, aided by hybrid AF. For macro enthusiasts, investment in good glass with Sony pays off significantly.

Low Light and Night / Astro Photography

Sony’s sensor excels in low light, with acceptable noise levels at ISO 3200 and beyond, and a minimum shutter speed of 30 seconds allows creative exposure control. The availability of RAW format processing enables advanced noise reduction and detail recovery in post.

Olympus tops out at ISO 1600, shutter speeds max at 1/2000 second but minimum at 4 seconds, but lacks RAW support, which reduces post-processing flexibility.

For astrophotography or challenging night conditions, the Sony provides far greater capability.

Video Capabilities

The Olympus 7040 shoots up to 720p HD at 30 fps, recorded in Motion JPEG format - quite basic by modern standards. It has no microphone port or external audio controls.

Sony’s A68 shoots Full HD 1080p at 60i and 30p, supporting widely used MPEG-4, AVCHD, and XAVC S codecs. It includes an external microphone input for better audio capture, widening its utility for videographers.

Neither support 4K recording, but Sony’s superior codec, higher frame rates, and audio options make it the clear winner for hybrid shooters who want good video alongside stills.

Battery Life and Storage Options

Battery life impacts whether you can confidently shoot all day.

Sony’s NP-FM500H battery rated for approximately 510 shots per charge is excellent for an entry-level DSLR and supports longer shooting sessions. Olympus’s battery specs aren’t listed, but compact cameras generally deliver fewer frames per charge, making spare batteries or chargers essential.

Both accept SD/SDHC cards with a single slot. Sony also supports Memory Stick Pro Duo, offering more compatibility for legacy users.

Connectivity and Extra Features

Neither camera offers Bluetooth or NFC, and neither has GPS embedded. Olympus has none of the wireless features and minimal interface ports besides USB 2.0 and HDMI. Sony edges out with Eye-Fi compatibility, enabling wireless image transfers through supported cards.

Illuminated buttons and touchscreens are not featured on either, reflecting their older generation designs.

Pricing and Value Proposition

At time of listing, Olympus 7040 comes in around $300, whereas the Sony A68 retails near $580. The near doubling in price reflects the Sony’s leaps in sensor size, AF, and versatility.

For casual shooters desiring an affordable, pocketable companion, Olympus offers value and simplicity. However, for enthusiasts needing image quality, control, and options for evolution in their gear, Sony’s A68 provides significantly greater capability with an expandable lens ecosystem.
