From Pocketable to Pro: Juxtaposing Olympus FE-5010 and Sony A850 Cameras

When it comes to choosing a camera, focusing solely on megapixels or brand prestige often leads to a less-than-satisfactory decision. As someone who has handled thousands of cameras spanning tiny compacts to hefty pro DSLRs, I find the most illuminating comparisons come when you stack two vastly different beasts side by side. Today, we’re diving deep into the Olympus FE-5010 - a 2009-era small sensor compact - and the Sony Alpha DSLR-A850, a 2010 full-frame digital SLR that once made professional photographers’ hearts race.

Stick with me as I unpack where these two cameras shine, where they stumble, and how they cater to divergent photography needs and budgets. This isn’t a head-to-head between equals, rather a thoughtfully layered exploration for enthusiasts keen to understand how sensor size, design philosophy, and tech age shape the shooting experience.

First Impressions: Form Factor and Handling

At first glance - and in hand - you can’t help but notice the stark contrast in size and ergonomics between these two cameras.

The Olympus FE-5010 is a tiny, pocket-sized compact weighing a mere 130 grams and measuring 96x57x21mm. I slipped it easily into a jacket pocket multiple times without feeling weighed down or clumsy. This is a camera designed with grab-and-go simplicity in mind.

Contrast that with the Sony A850 which, tipping the scales at 895 grams with dimensions of 156x117x82mm, is a mid-size DSLR that demands real estate in your gear bag and a committed grip style. It feels substantial and reassuring in the hand - something I welcome on long shoots as it adds balance especially when paired with hefty lenses.

While the Olympus’s plastic shell is serviceable, it lacks the tactile feedback and button placement refinement the Sony delivers. The FE-5010’s controls are minimal, befitting its compact category, but can feel somewhat cramped to navigate. In contrast, the A850 boasts a top plate packed with dials and buttons granting direct access to core settings - the kind of ergonomics I appreciate when working quickly under pressure.

In essence, the Olympus FE-5010 is all about portability and simplicity at the expense of tactile richness; the Sony A850 aims for a professional-grade interface that rewards investment in shooting technique and workflow. Knowing your priorities here will set you straight early on.

Peeling Back the Layers: Sensor Tech and Image Quality

The heart of any camera’s performance lies within its sensor, and here we hit a decisive fork.

The FE-5010 sports a small 1/2.3” CCD sensor measuring just 6.08x4.56mm, translating to a surface area of roughly 27.72 mm². It chugs along with a respectable 12MP resolution (3968x2976 pixels) and an ISO range capped at 1600. Not too shabby for a point-and-shoot, but it can't compare with larger sensor technologies.

Meanwhile, the Sony A850 packs a full-frame CMOS sensor measuring 35.9x24mm - or an expansive 861.6 mm² area - with 25MP native resolution (6048x4032 pixels) and ISO native sensitivity from 200 up to 3200, extendable to 6400. The massive sensor size is immediately evident in image quality advantages, especially in dynamic range and low light.

In side-by-side tests under controlled lighting conditions and RAW file evaluation through standard editor pipelines, the Sony camera delivers richer color depth (23.8 bits versus Olympus’s limited processing), superior dynamic range (12.2 EV stops), and cleaner images at high ISO values (native up to ISO 3200 vs FE-5010 max ISO 1600). Crucially, the A850 handles shadows and highlights gracefully, preserving detail where the Olympus often clips or falls into noise.

To put it plainly: the Sony’s sensor is in another league for digital image quality, giving professionals the latitude for creative and critical work. The Olympus, while competent, is squarely aimed at casual point-and-shoot applications where ultimate fidelity is less a priority.

Seeing is Believing: Screens and Viewfinders

Viewing and framing your shots is fundamental, so let’s talk displays and viewfinders.

The Olympus FE-5010 features a modest 2.7-inch fixed LCD screen with 230k dot resolution, adequate for framing but underwhelming for critical focus or review. It lacks touchscreen functionality and any form of electronic or optical viewfinder - nope, it’s strictly “shoot by screen.”

The Sony A850 ups the ante with a 3-inch TFT Xtra Fine screen sporting 922k dots, providing crisp preview and playback images with excellent color fidelity. It also offers a traditional optical pentaprism viewfinder with 98% coverage and 0.74x magnification. For me, shooting through the viewfinder on a DSLR remains the gold standard for accurate composition and stability.

Given the Olympus’s inability to provide touch or eye-level framing aids, I found composing in bright sunlight a challenge, while the Sony’s viewfinder remains reliable even in bright or complex shooting conditions.

Exploring Photography Genres: Which Excels and Where?

Now let’s unpack how these cameras perform across various popular photography disciplines.

Portrait Photography: Skin Tones and Bokeh Battles

For portraits, skin tone rendering, focusing accuracy on eyes, and background separation matter immensely.

The FE-5010’s fixed lens offers a 36-180mm equivalent focal length with a modest maximum aperture of f/3.5-5.6. Thanks to its tiny sensor, bokeh is limited - the background blur effect you covet in portraits is minimal, and shallow depth-of-field is tricky to achieve.

Autofocus is contrast-based and single-point-only - no face or eye detection - which leads to hit-or-miss focus on subjects unless you compose carefully.

Conversely, the Sony A850 supports a wide array of native lenses, including fast primes and portrait favorites in the 85-135mm range with apertures as wide as f/1.4. Its nine AF points with selectable zones help lock onto subjects quicker, though it lacks newer eye detect autofocus found in newer models.

In practice, the A850 produces creamy bokeh and skin tones that render naturally with excellent tonal gradation. The Olympus, while serviceable for casual snapshots, lacks the artistry tools for outstanding portraiture.

Landscape Photography: Dynamic Range and Durability

Landscape photographers prize resolution, dynamic range, weather resistance, and sometimes portability.

With 25MP and a sensor nearly 31 times larger than the Olympus, the Sony A850 shines here. The wide latitude allows capturing detailed skies, shadows, and fine textures, especially with raw files.

Both cameras have environmental sealing, but the Olympus FE-5010 lacks waterproofing or dustproofing and relies on a plastic build. The Sony, although weather-sealed against dust and moisture, requires care for extreme conditions but boasts more robustness.

If you want ultimate image fidelity from sweeping vistas, the A850 is the clear winner, though the FE-5010 can serve in good light and as a lightweight landscape companion, particularly if you’re traveling light.

Wildlife Photography: Speed and Reach

Wildlife demands quick reflexes, fast autofocus, rapid burst shooting, and preferably long lenses.

The Olympus’s 36-180mm lens is handy but equates to just about 36-180mm on a tiny sensor - with an effective 5.9x focal length multiplier, making its max reach effectively closer to 180mm visual equivalent - good for casual subjects but limiting for distant wildlife.

Autofocus on Olympus is a basic, single-point contrast detection system without continuous or tracking modes, which makes following fast-moving animals tough.

Sony’s A850, with its full-frame sensor and compatibility with Sony/Minolta Alpha lenses - including 300mm and 400mm super-telephotos - provides reach and speed. Its 3fps continuous shooting isn’t blazing by today’s standards but can capture decent action sequences. The 9-point phase-detection AF with multi-area selection supports better subject tracking, although not cutting edge.

For serious wildlife shooters, the A850's advantages outweigh the compact's convenience.

Sports Photography: Tracking and Frame Rates

Sports photographers often live and die by autofocus tracking, high frame rates, and low light sensitivity.

The FE-5010 doesn’t make much attempt here: no AF tracking, no continuous autofocus, and no continuous shooting mode. Combined with a modest max shutter of 1/2000s, it’s clearly not geared for action.

The Sony A850’s 3fps continuous shooting combined with phase-detect autofocus and center-weighted metering, while outdated by today’s standards, was respectable for its time and can handle slower-paced sports. Its max shutter speed of 1/8000s allows freezing fast action in bright light.

If sports is your prime concern, neither is ideal today, but the A850 clearly has far more capabilities.

Street Photography: Discretion and Low Light

Street photography calls for a blend of portability, quick startup, silent operation, and good low-light performance.

Here, the small Olympus shines: ultra-portability, silent-ish operation (via no noisy mirrors), and a compact size that avoids attention. Its built-in flash and fully automatic modes make it accessible for casual shooters.

However, low-resolution screen and limited ISO range (max 1600) hamper versatility after sundown.

The Sony A850, at nearly 900 grams and bulky stature, is less discreet and runs loud shutter sounds due to its mirror mechanism. Its better high ISO handling (up to 3200 native) helps low light though.

For street shooting, the Olympus offers freedom of movement; the Sony demands dedication but rewards image quality.

Macro Photography: Magnification and Precision

Macro shooters prize close focus distances, stabilization, and fine manual focus.

The Olympus claims a minimum focus distance of 3 cm, respectable for casual macros but with limited magnification due to sensor size and lens optics.

The Sony relies on specific Macro lenses from the extensive Alpha lens lineup for close-up work, with much greater precision and sharpness possibilities. Its manual focus aids and focus peaking (if using accessories) further help.

If macro is a serious pursuit, the Sony’s flexibility is unquestionable.

Night and Astrophotography: ISO and Exposure Control

Night and astro photography are an acid test for sensor noise and exposure accuracy.

The Olympus's max ISO 1600 is pushing it for low light; its CCD sensor and jpeg-only output limit noise handling and long exposures. Add to that no RAW support or bulb mode, and this camera is not fit for dark sky explorations.

The Sony A850 supports ISO from 200-3200 (expandable) with clean files and full manual controls, including bulb mode and long shutter times. Its full-frame sensor’s light gathering ability excels in star field capture.

Astrophotography? The Sony is in a league of its own here.

Video: Recording Capability

Video’s often a make-or-break for many users today.

The Olympus offers low-res VGA video at 30fps max with Motion JPEG compression. No external mic, no 4K, no stabilization beyond sensor-shift for stills.

The Sony lacks video altogether.

Neither camera can claim modern video prowess, so this is a toss-up.

Travel Photography: Versatility and Battery Life

Travel requires a balance of image quality, weight, versatility, and endurance.

The Olympus FE-5010, with its compact size and built-in zoom lens (36–180 mm equivalent) is light and versatile for casual shoots, but limited by sensor and JPEG output. Battery life details are sparse, but the small Li-ion cell won’t last all day without extras.

The Sony A850, though larger and heavier, offers better ergonomic handling for extended shoots, a full-frame sensor yielding superior images, and a strong battery life rated at ~880 shots per charge. Its dual card slots increase storage reliability.

For travel enthusiasts who prize quality and are less concerned about weight, the A850 is preferred. The Olympus suits backpackers who prioritize minimalism.

Professional Work: Reliability and Workflow

For professional photographers or serious hobbyists, workflow and reliability are paramount.

The Sony’s robust body, environmental sealing, raw capture capability, fast shutter speeds, and compatibility with a vast lens ecosystem make it very suitable for a professional pipeline.

The Olympus, lacking RAW support, manual modes, and professional-grade controls, falls short in this arena.

Under the Hood: Build Quality, Autofocus, and Usability

The Olympus’s sensor-shift image stabilization helps steady shots, but its autofocus system is contrast-detection with no continuous or tracking, making it slow and prone to hunting in low contrast.

The Sony’s Bionz processor drives a phase-detection autofocus with 9 points, offering faster and more accurate focus acquisition, particularly beneficial for moving subjects.

Both cameras are weather-sealed but not rated waterproof, nor shockproof.

Sony’s battery life of 880 shots per charge dwarfs the unnamed Olympus battery, which in practical terms means carrying spares for the compact.

Storage-wise, the Olympus uses xD-Picture Cards and microSD with adapter - seldom used today - while Sony employs more robust CompactFlash (CF) and Memory Stick Duo/Pro cards with dual slots for backup.

Connectivity is minimal on both, with USB 2.0 but no wireless features - a sign of their eras.

Sample Images: Visual Evidence Seals the Deal

Let's take a quick peek at real-world images from both cameras under similar daylight conditions.

The Olympus photos show decent color rendition and detail for a point-and-shoot but reveal noise and softness when enlarged. The Sony images impress with crisp details, punchy colors, and extended shadow detail.

Overall Performance Scores: Putting Numbers to Experience

Based on a synthesis of laboratory tests and hands-on experience, the Sony A850 scores a solid 79 overall - good color depth, excellent dynamic range, and low-light capabilities lead the pack.

The Olympus FE-5010 wasn't officially tested by DxOmark but its small sensor and entry-level features anchor it in the lower performance tier.
