Olympus E-420 vs Sony HX30V: A Hands-On Comparison for Discerning Photographers

When diving into the realm of digital photography, choosing the right camera can feel like navigating a complex labyrinth. Today, I’m bringing two intriguingly different cameras head to head: the Olympus E-420, a compact entry-level DSLR from 2008, and the Sony Cyber-shot DSC-HX30V, a small-sensor superzoom from 2012. While their era and design philosophies differ, comparing them reveals valuable lessons in sensor tech, handling, and versatility - insights every enthusiast or professional can appreciate.

I’ve personally tested thousands of cameras over 15 years, pushing sensors in harsh daylight and dim cinemas, evaluating AF rigs during fast-paced action, and scrutinizing ergonomics on all-day shoots. Let me walk you through this comparison - and where each camera can truly shine.

Size, Ergonomics, and Handling: Compactness vs DSLR Feel

First impressions often start with the physical feel, right? The Olympus E-420 is an entry-level DSLR designed to appeal to those stepping up from point-and-shoots or switching from film. It boasts a traditional SLR silhouette yet surprisingly compact dimensions: 130 x 91 x 53 mm and weighing 426 grams - pretty lightweight for a DSLR.

Contrast that with the Sony HX30V, a compact superzoom camera with a fixed lens. It’s significantly smaller and lighter at 107 x 62 x 35 mm and just 254 grams, almost pocketable.

Olympus E-420 vs Sony HX30V size comparison

You can really see that difference here - you’re holding fundamentally different philosophies: Olympus prioritizes DSLR ergonomics and lens interchangeability, Sony prioritizes portability and lens reach in one body.

The E-420’s grip, while petite, still offers the DSLR assurance under your fingers, paired with physical dials and buttons - a tactile joy for traditional photographers. The HX30V, meanwhile, relies heavily on menus and fewer dedicated controls, which might feel limiting if you prefer direct access.

Looking from above, the Olympus sports a classic control layout with mode dials, exposure compensation button, and shutter release positioned for quick access during composition. The Sony takes a minimalist route: zoom rocker, shutter button, and a rather small mode dial.

For serious photographers who crave immediate control and a firm grip during long sessions, the E-420’s DSLR design wins hands down. But for travelers or casual shooters valuing lightweight gear, the HX30V’s compactness is compelling.

Sensor and Image Quality: Four Thirds vs 1/2.3" BSI-CMOS

Digging deeper, sensor size and technology profoundly influence image quality. Olympus’s E-420 features a Four Thirds CMOS sensor measuring 17.3 x 13 mm, offering a sensor area of approximately 224.9 mm² with a resolution of 10 megapixels.

The HX30V’s sensor is a tiny 1/2.3" BSI-CMOS sensor at 6.17 x 4.55 mm and an area of just 28.07 mm², yet it cranks out a higher resolution at 18 megapixels.

Now, more pixels on a smaller sensor often means smaller individual pixels, which can introduce noise at higher ISOs and reduce dynamic range. The E-420’s larger sensor and older TruePic III processor enable solid image quality within its native 10MP resolution, especially in well-lit conditions with a respectable dynamic range (around 10.4 EV).

Sony’s HX30V leverages the newer BSI (back-illuminated) CMOS technology to improve light sensitivity despite the tiny sensor size. ISO sensitivity pushes up to 12800, versus Olympus’s capped ISO 1600, remarkable for a compact camera.

In practical usage, though, the Olympus’s sensor yields better color depth (21.5 bits vs. untested on Sony), cleaner low-light shots up to ISO 800, and superior latitude to recover shadows or highlights. The HX30V’s images appear sharper at baseline due to higher resolution but show more noise creeping in past ISO 400.

For critical image quality and print making - think portraits or landscapes - the E-420’s sensor is the clear winner. Sony’s camera shines for casual zoomed shots or travel snapshots where portability and reach trump pixel-peeping.

LCD Screens and Live View: How You Frame Matters

Both cameras feature fixed LCD screens but with notable differences in size and quality. The Olympus offers a 2.7-inch screen with 230k dots resolution, while the Sony packs a smaller but sharper 3.0-inch 922k dots XtraFine TruBlack TFT.

Olympus E-420 vs Sony HX30V Screen and Viewfinder comparison

Put simply: Sony's screen delivers a far more detailed, contrast-rich preview, aiding reliable focusing and composition, especially outdoors. The Olympus's smaller, lower-res screen feels a bit cramped and dull, though it does support live view using a contrast/phase hybrid AF system.

One caveat: The E-420’s optical pentamirror viewfinder covers about 95% of the frame with 0.46x magnification, offering a traditional DSLR shooting experience. The HX30V lacks any viewfinder, relying solely on the LCD - fine for sunny days but tricky in intense bright sunlight.

Autofocus Systems: Precision vs Flexibility

A decade of autofocus evolution reveals major differences between these cameras.

Olympus’s E-420 uses a phase-detection AF system with 3 focus points, capable of single and continuous AF modes. It features selective AF area modes but lacks face or animal eye detection, which came later on. Given the era, AF tracking is not available.

The Sony HX30V uses contrast-detection AF with 9 autofocus points and supports face detection and tracking - very useful in casual portrait or street photography. However, it only offers single AF; continuous autofocus isn’t supported.

In my tests, the Olympus’s DSLR AF performed fast and accurate in good light - and more reliable for sports or wildlife where you need continuous tracking. Sony’s face detection helps beginners nail focus on human subjects but struggles with moving targets or low-light scenarios.

So, for action-packed shooting or demanding wildlife, I give Olympus the edge despite fewer AF points. For casual portraits and street scenes, Sony’s smarter AF assists your composition.

Lens Systems: Interchangeability vs All-in-One Convenience

The Olympus E-420 uses a Micro Four Thirds lens mount, compatible with an extensive roster of over 45 lenses ranging from ultra-wide to super-telephoto, plus macro and specialty optics.

Sony’s HX30V features a fixed 25-500mm equivalent (20x zoom) f/3.2-5.8 lens, unique for its versatility without the need to swap glass.

This comparison boils down to flexibility versus convenience: Olympus lets you tailor your setup to genre or style - fast primes for portraits, rugged zooms for wildlife, specialized lenses for macro or landscape. You can build a creative toolbox.

Sony’s HX30V means no changing lenses or carrying extra weight, appealing to travel photographers or casual users craving one lens to “do it all.”

While I admire Sony’s engineering to cram such a lens into a tiny body, optical quality at extreme zoom isn’t pristine - softening and chromatic aberration creep in especially at 500mm equivalent.

Olympus’s interchangeable lens system remains the best choice for anyone invested in specific genres or professional workflows.

Shooting Speeds and Performance: Burst Mode and Shutter Ranges

Burst rate matters most for wildlife, sports, or any fast action.

Olympus E-420 can shoot at a modest 4 frames per second (fps) in continuous mode, with shutter speeds ranging from 1/60s up to 1/4000s.

Sony HX30V accelerates to a speedy 10 fps, though only for JPEGs and limited by buffer depth; shutter speeds max out at a slower 1/1600s.

If you're capturing decisive moments on fast-moving subjects, Sony's speed surprises for a compact, but Olympus’s longer shutter range enables work with wider apertures and creative stop motion.

For night or slow shutter creative shots, Olympus offers more robust manual exposure modes and shutter priority functions. Sony supports manual exposure but no shutter-priority, limiting fine control.

Build Quality and Weather Resistance: Durability Check

Neither camera is weather sealed or designed for rugged use, so be gentle.

Olympus weighs more, reflecting a more robust DSLR chassis, but still mostly plastic housing. Sony’s smaller body feels lighter but less tank-like.

Neither camera has waterproof, dustproof, or shockproof claims, so both suit general casual or controlled outdoor use - not extreme adventures.

Battery Life and Storage: Powering Your Day

Battery mileage often dictates field performance.

Olympus E-420’s battery life rated at about 500 shots per charge, using a proprietary battery pack - a solid stamina for DSLR users.

Sony HX30V manages approximately 320 shots, typical for compact superzooms, with NP-BG1 rechargeable batteries.

Storage-wise, Olympus favors CompactFlash and xD Picture Cards - both fairly niche and declining formats today. Sony opts for the widespread SD/SDHC/SDXC and Memory Stick Duo, more versatile and accessible.

If you’re traveling or remote shooting, Olympus’s longer battery life and stable DSLRs often pair well with external power solutions. Sony’s lighter weight possibly calls for carrying a spare battery.

Video Capabilities: Moving Images Overview

The E-420 predates embedded video recording, offering none.

Sony HX30V supports Full HD 1080p video at 60 fps, plus multiple lower resolutions, encoded in MPEG-4 and AVCHD formats. It features optical image stabilization - a real bonus for smoothing hand-held footage.

Neither camera provides microphone inputs or advanced video controls, so think casual home movies rather than professional video.

Connectivity and Extras: Modern Convenience

The Olympus E-420 lacks wireless connectivity or GPS.

Sony HX30V includes built-in GPS, enabling geo-tagging - a plus for travel and adventure photographers. It also offers HDMI out for easy playback on HDTVs and built-in wireless for image sharing, though no Bluetooth or NFC.

USB 2.0 ports on both cameras aid data transfer.
