Olympus E-450 vs Sony HX20V: An Expert Comparison for Photography Enthusiasts

Choosing between cameras as different as the Olympus E-450 and Sony HX20V demands more than just a glance at their specs - it requires a nuanced understanding of how each will perform in the real world, across various photography disciplines. Having tested thousands of cameras over 15 years, I’ve developed a keen sense for how sensor size, autofocus, ergonomics, and many other factors influence actual photographic results. In this comparison, I’m laying out everything I’ve observed, so you can find which camera better suits your style and needs.

Let’s embark on this journey with physicality - because if a camera doesn’t feel right, everything else can become an uphill battle.

Handling and Ergonomics: How They Feel in Your Hands

The Olympus E-450 is a compact DSLR with a solid build tailored for entry-level photographers seeking a comfortable grip and manual control. It weighs 426g and measures 130x91x53mm, while the Sony HX20V is a pocket-friendly compact camera at 254g and 107x62x35mm, designed for grab-and-go convenience.

The Olympus features a traditional optical pentamirror viewfinder (though not very bright with its 95% coverage and 0.46x magnification) and a 2.7-inch fixed LCD with 230k dots. Its control layout includes dedicated dials for shutter priority, aperture priority, and manual exposure - a boon for someone who likes tactile, instant access to key settings.

On the other hand, the Sony HX20V opts out of a viewfinder, relying on a 3-inch, high-resolution (922k dots) XtraFine TruBlack TFT LCD. It lacks dedicated exposure mode dials; instead, settings are adjusted through menus, which can slow you down if quick shooting adjustments are your thing.

If ergonomics and button positioning rank high on your list, Olympus’s more DSLR-style layout wins favor. Conversely, if you prioritize portability and a bright, high-res screen for composing and reviewing shots, the Sony outshines its rival.

Sensor Size and Image Quality – The Bigger the Sensor, the Better?

At the heart of any camera’s image capabilities lies its sensor. The Olympus E-450’s Four Thirds 17.3x13mm CMOS sensor offers 10 megapixels, while the Sony HX20V packs an 18-megapixel 1/2.3-inch BSI-CMOS sensor, measuring just 6.17x4.55mm.

The Four Thirds sensor area is approximately 224.9 mm² - nearly eight times larger than the Sony’s small sensor at 28.07 mm². Sensor size profoundly impacts noise performance, dynamic range, depth of field control, and overall image quality.

Although the Sony boasts a higher megapixel count, that doesn’t necessarily translate to better images. In fact, the larger pixels on the Olympus translate to a cleaner signal, particularly at higher ISOs. The Olympus tops out at ISO 1600 natively, while the Sony extends up to ISO 12800 - though its smaller sensor means noise deteriorates image quality quickly beyond ISO 800 or so.

In terms of color depth and dynamic range - based on DxOMark benchmarks - the Olympus has a color depth of 21.5 bits with a dynamic range of 10.5 EV, superior to the typical range achievable by a small compact sensor like the Sony’s (which is untested by DxOMark but known to be more limited).

This tangible difference makes the Olympus better suited for photographers who want cleaner images, especially in challenging light or who value print quality.

Autofocus Performance: Fast, Accurate or Just Functional?

The Olympus uses a hybrid autofocus system with 3 focus points relying on phase detection and contrast detection, offering continuous autofocus. The Sony HX20V uses contrast detection focusing with 9 focus points and face detection capabilities, though no phase detect AF.

For portraits and general photography, the Sony’s face detection brings an advantage - it can quickly settle focus on human faces, making it easier for casual shooting.

However, in real-world testing, the Olympus’s phase detection AF system results in consistently faster focusing speed and more accurate tracking in continuous AF mode, particularly useful for moving subjects in wildlife or sports scenarios. The Sony’s autofocus, while decent for a compact, occasionally hunts in low light or low contrast areas.

Neither camera excels at subject tracking due to limited AF points and no advanced tracking algorithms, but the Olympus edges ahead in autofocus responsiveness and continuous shooting, partly due to its DSLR heritage.

Portrait Photography: Rendering Skin Tones and Bokeh

Portraiture is where sensor size and lens control shine. The Olympus E-450, paired with optics using the Four Thirds lens mount, benefits from a vast lens ecosystem (45 lenses available) that includes fast primes for creamy bokeh. The focal length multiplier of 2.1x means a 25mm lens behaves like roughly a 50mm full-frame lens - great for portraits.

By contrast, the Sony HX20V’s fixed 25-500mm (20x zoom) lens has a variable aperture of f/3.2–5.8. While it offers versatility, it cannot match a fast prime’s shallow depth of field. Bokeh is more limited, often harsh, and less subject-isolating.

Color rendition on skin tones favors the Olympus - its larger sensor and TruePic III processor produce natural, well saturated results without harshness. Sony’s processing sometimes leans toward punchier but less natural hues.

Neither camera has eye autofocus or animal eye detect technology, so nailing sharp focus on the eyes demands patience or manual focus knack with the Olympus.

Landscape Photography: Colors, Dynamic Range, and Durability

Landscape photographers prize dynamic range to capture detail in shadows and highlights, often relying on raw shooting for post-processing flexibility. The Olympus supports raw image files, offering greater latitude for editing, while the Sony does not support raw capture, limiting post-processing potential.

The Olympus’s superior dynamic range of 10.5 EV means it better handles contrasty scenes, preserving detail in bright skies and dark foregrounds.

Both cameras lack weather sealing, which somewhat restricts use in rugged outdoor environments. The Olympus is more ruggedly built but not weatherproof; the Sony is smaller and less robust.

Resolution-wise, the Sony’s higher megapixel count can tempt for fine detail; however, the small sensor compromises detail retention in shadows and highlights compared to the Olympus’s cleaner tonal gradations.

Wildlife Photography and Zoom Performance: Who’s Faster on the Draw?

Wildlife photography demands fast autofocus, long focal lengths, and rapid burst capability. Here, the Sony HX20V’s 20x zoom range (25-500mm equivalent) offers striking reach in a compact package.

Olympus E-450’s 2.1x crop factor means you’d need a 300mm Four Thirds lens for comparable focal length, which tends to be bulkier and pricier.

Regarding burst shooting, Olympus delivers 4 fps continuous shooting, sufficient for many casual wildlife scenarios. The Sony claims 10 fps, but it’s limited by buffer and slower AF in continuous mode (which the Sony lacks).

Autofocus speed favors Olympus, while zoom versatility and reach belong to Sony.

Sports Photography: Tracking, Shutter Speeds, and Sensitivity

Sports photography is not the forte of either camera since both were designed outside fast action shooting. The Olympus shutter speed tops out at 1/4000s with no electronic shutter option, while the Sony’s max shutter speed is only 1/1600s. For freezing fast athletes, Olympus’s higher shutter speed provides more flexibility.

Olympus also offers shutter, aperture, and manual modes, allowing precise exposure control in dynamic lighting, whereas Sony lacks dedicated exposure modes like shutter priority.

Low light sensitivity limits keep both cameras suboptimal for indoor sports; however, Olympus’s native ISO 1600 and cleaner noise performance gain a slight upper hand.

Street Photography: Discretion, Speed, and Portability

Street photography benefits from compactness, low noise, fast startup, and silent operation. Sony’s HX20V bulletproofs here as a discreet, pocketable superzoom with silent focusing and no mechanical viewfinder noise.

Olympus, by contrast, is bulkier, louder, and less stealthy due to its DSLR design and built-in flash.

Low-light performance is similar in both - neither is stellar, but Olympus’s larger sensor means less noise.

If portability and rapid candid shots matter most, Sony appeals more. For controlled street portraits or creative shallow depth shots, Olympus’s manual controls and lens options provide extra firepower.

Macro Photography: Close Focus and Stabilization

The Sony HX20V offers 1cm macro focusing - superb for extreme close-ups without additional gear. Plus, the built-in optical image stabilization smooths handheld macro work.

Olympus lacks built-in stabilization. Macro capabilities depend on the lens. While Four Thirds has excellent macro lenses, Olympus E-450’s price point and lens kit typically mean less specialized macro glass unless you invest further.

Therefore, for spontaneous, casual macro, Sony’s fixed lens setup is more convenient; for serious macro enthusiasts willing to add lenses, Olympus offers more potential.

Night and Astro Photography: High ISO and Long Exposures

Astro photographers demand low noise at high ISOs and reliable bulb or extended shutter modes. Olympus E-450 excels here with ISO up to 1600 and shutter speeds ranging from 60s to 1/4000s, perfect for long exposures.

Sony’s shutter tops at 30 seconds and max ISO 12800 but small sensor size results in noisy images at higher ISOs. Plus, lack of raw files hampers noise reduction and detail recovery in post.

Olympus’s support for raw format and manual exposure modes allow precise control. Combined with larger sensor noise advantages, Olympus is superior for night sky captures.

Video Capabilities: Full HD Recording on a Budget?

Here the Sony HX20V clearly leads, offering Full HD 1080p video at 60 fps, and options at lower resolutions as well. It uses the BIONZ processor for smooth video compression with MPEG-4 and AVCHD formats.

Olympus E-450 lacks video recording outright - no video specs, no video formats.

If video integration is important in your workflow, Sony is the obvious choice despite lack of advanced video features seen on newer models.

Travel Photography: Versatility, Battery Life, and Convenience

Travel photography often demands lightweight, versatile gear with robust battery life.

Sony HX20V’s compact form and 20x zoom lens cover a huge range without lens changes - perfect for travel. GPS tagging is built-in, enhancing location tracking (a feature missing on Olympus).

Battery life: Olympus offers 500 shots per charge (CIPA standard), while Sony’s rated at 320 shots. Olympus’s DSLR battery capacity is better but with the cost of heavier weight and bulk.

Storage media: Olympus uses Compact Flash & xD cards, which are becoming rarer and more expensive; Sony uses SD cards, widely popular and convenient.

Overall, Sony’s compactness, zoom range, and convenience suit casual travel; Olympus’s image quality and controls favor those prioritizing quality over size.

Professional Use and Workflow Integration

For professional photographers, image quality, file format flexibility, lens ecosystem, and reliability matter most.

Olympus’s key advantage: raw file support, Four Thirds lens mount for accessing pro quality lenses, and manual control modes.

Sony’s fixed lens system and lack of raw format seriously limit professional workflows, leaving it in an enthusiast or casual user bracket.

Neither camera is weather sealed or built for rugged professional use, nor do they boast advanced tethering or connectivity, which is now standard on pro bodies.
