Sony A230 vs RX100 III: A Real-World Photographer’s Comparison Across Genres and Tech

When I first laid hands on the Sony Alpha DSLR-A230 and the Sony Cyber-shot DSC-RX100 III, it was immediately clear how differently these two cameras align with distinct photographic ambitions - even though both hail from Sony’s impressive lineage. The A230, a 2009 entry-level DSLR, and the 2014 RX100 III, a compact large-sensor powerhouse, have carved out unique niches.

I’ve tested both through thousands of shots and varied scenarios, so if you’re aiming to decide which camera suits your style - whether portrait, landscape, wildlife, or studio work - read on. I’ll unpack the technical details, real-world performance, and value analysis with the kind of hands-on insight only experience grants.

Tangible Handling and Design: Size, Feel, and Control

The first thing you’ll notice picking up the A230 versus the RX100 III is their foundational build philosophies.

The A230 is a traditional DSLR with a solid grip and heftier 490g weight spread across a 128 x 97 x 68 mm body. Handling real lenses with manual focus rings and a mechanical shutter appeals if you like tactile engagement. Its body offers straightforward ergonomics but feels dated, particularly in button illumination and customization.

Contrast that with the RX100 III’s compact 102 x 58 x 41 mm, 290g design - a pocket-friendly large sensor compact. Its tilting 3" screen and electronic viewfinder (EVF) deliver a modern experience despite the smaller grip surface. The RX100 III shines if portability and quick grab shots dominate your shooting habits.

Control-wise, the A230 relies on a traditional DSLR layout with mode dials and dedicated buttons for exposure modes, offering muscle memory benefits if switching lenses and manual dials are your workflow staples. The RX100 III’s streamlined layout leans on a control dial and a few function buttons, reflecting its compact form while still providing quick access to essential settings.

Sensor and Image Quality: Pixels Meet Light Sensitivity

Sensor tech has evolved significantly between these models - and the effect on image quality is striking.

The A230 sports a 10MP APS-C CCD sensor (23.5 x 15.7 mm), delivering solid resolution and dynamic range for its time. CCD sensors historically offered excellent color depth - confirmed by its 22.3-bit color depth rating - and a wider native ISO care of 100-3200, though with a maximum boosted ISO sensitivity well shy by today’s standards. Notably, its low-light performance is moderate (ISO low-light score of 531), meaning noise becomes noticeable beyond ISO 800 - expected for a camera over a decade old.

Flip to the RX100 III with its 20MP 1-inch BSI-CMOS sensor (13.2 x 8.8 mm), boasting higher pixel count and notably better dynamic range (12.3 EV versus the A230’s 11.4 EV). The CMOS technology and backside illumination design favor cleaner high-ISO results, especially important for low light and telephoto work. The RX100 III maxes out at ISO 12800, though practically, usable images top out near ISO 3200 in real-world shooting. Still, this sensor yields sharper images with better detail retention and less noise.

The RX100 III offers multiple aspect ratios (1:1, 4:3, 3:2, 16:9), unlike the A230’s more limited 3:2 and 16:9, providing creative flexibility. And yes, the RX100 III’s max resolution of 5472 x 3648 pixels trumps A230’s 3872 x 2592, lending more room for cropping or large-format prints.

Viewing and Interface: Through the Eye and on the Screen

In on-the-go photography, viewfinder quality and LCD usability influence your shooting speed and comfort.

The A230 features a 2.7” fixed LCD with a modest 230k-dot resolution - adequate in bright daylight but lacking in tactile responsiveness since it’s non-touchscreen. More importantly, its pentamirror optical viewfinder covers only 95% of the image frame - subtle composition nuances could be missed.

The RX100 III counters with a 3” tilting LCD boasting 1229k dots, granting vibrant, high-resolution previews and shooting angle versatility - especially useful for street or low-angle shots. Its pop-up electronic viewfinder (EVF) covers 100%, presenting exactly what you capture - not approximations. The EVF resolution (1440k dots) offers crisp, lag-free framing even in challenging light.

The RX100 III’s live view autofocus responsiveness also surpasses the A230’s lack of live view entirely. This difference can be make-or-break for video and precise focusing scenarios.

Autofocus Systems: Tracking the Perfect Moment

Autofocus speed and accuracy influence your success in dynamic or critical-focused shoots like wildlife and sports.

The A230 has a 9-point autofocus system using hybrid phase/contrast detection with no face or eye detect. It can shoot at 3 fps but lacks tracking capability or continuous face detection, and the focusing is slower due to older CCD-induced readout speeds.

The RX100 III improves significantly with 25 contrast-detection AF points, center-weighted AF, and live view AF including face detection and AF tracking. Continuous shooting at 10fps under these conditions is impressive for such a small camera. This agility allows nailing fleeting moments in street or action photography reliably.

Performance Across Photography Genres

Let’s dive into how these differences play out in real-world photographic genres.

Portrait Photography: Skin, Bokeh, and Eye Detection

Portraiture benefits from nuanced skin tone rendering, smooth bokeh, and reliable eye AF.

The large APS-C sensor on the A230 inherently produces shallower depth-of-field (DoF) for the same aperture, allowing creamier backgrounds when paired with lenses like the 50mm f/1.8. CCD sensor colors render warm, pleasant skin tones with good gradation.

On the other hand, the RX100 III has a smaller 1” sensor but a notably fast lens (f/1.8-2.8), which can still isolate subjects well, especially at 70mm equivalent. Crucially, it features face detection autofocus, making candid portraits easier, although it lacks eye AF proper.

For studio or controlled portraiture, the A230’s support for interchangeable lenses and manual focus rings wins. If you prefer quick handheld portraits with less gear, RX100 III performs commendably.

Landscape Photography: Dynamic Range, Detail, and Build

Here the A230 and RX100 III distances narrow.

Despite the older sensor, the A230’s APS-C size and 11.4 EV dynamic range suffice for capturing expansive scenes with highlight and shadow retention. The larger sensor also helps with less diffraction at smaller apertures when shooting for maximum depth of field.

The RX100 III excels slightly with improved 12.3 EV dynamic range and higher resolution. The tilting LCD aids composing in tricky positions, but the fixed zoom limits framing compared to DSLR zoom lenses.

Neither camera offers weather sealing, so be mindful in damp or dust environments during landscapes.

Wildlife and Sports: Autofocus, Burst Speed, and Telephoto Reach

For fast subjects, the RX100 III shines due to its faster continuous shooting (10fps) versus the A230’s 3fps, and superior autofocus tracking in live view.

However, lens reach needs consideration: the A230’s Sony/Minolta mount accesses a vast lens library, including super-telephotos (300mm+), vital for distant wildlife shots. The RX100 III’s limited 24-70mm zoom restricts reach - though its high-res sensor can crop intelligently.

This makes the A230 favorable for dedicated wildlife photographers prioritizing super-tele optics; RX100 III suits casual sports photographers valuing speed and portability.

Street and Travel Photography: Discretion and Convenience

Portability tips this in favor of the RX100 III, which fits easily in pockets, weighs 290g, and offers silent electronic shutter operation - ideal for discreet street shooting.

The A230’s bulk and DSLR shutter noise make it less suitable for stealth. Also, with no live view and a sluggish AF system, quick candid shots are tougher.

Travel photographers gain from the RX100 III’s built-in stabilized lens, wifi connectivity for instant sharing, and longer battery life (320 shots vs 230). The A230’s larger battery pack is good for bulkier shooting but requires extra lenses and gear.

Macro and Close-Up Work

The RX100 III supports 5cm macro focusing, enabling impressive close-ups without accessories.

The A230’s macro capability depends on lenses chosen but generally requires dedicated macro glass. The camera’s manual focus helps here, but overall versatility comes at higher cost and bulk.

Night and Astro Photography

The A230’s max ISO 3200 and CCD sensor impose limits. Noise surfaces early, and manual bulb mode alongside good tripod use is essential.

The RX100 III’s BSI-CMOS sensor and ISO up to 12800 improve night shots, with better noise control for long exposures. Video with slower frame rates also permits moonlight or night sky timelapse.

Video Capabilities: Modern Standards vs None

The RX100 III offers Full HD video up to 60 fps with dedicated video formats (MPEG-4, AVCHD, XAVC S) and optical image stabilization. Though it lacks microphone input, video enthusiasts will appreciate the quality in a compact form.

The A230 has no video recording features.

Professional Workflow and Reliability

For professionals, RAW support exists on both cameras, aiding post-processing flexibility.

The A230’s solid build and lens interchangeability suit varied pro environments; however, it misses modern connectivity standards such as Wi-Fi or NFC, delaying workflows.

The RX100 III offers built-in wireless for easy transfer and compatible mobile apps, though its fixed lens limits adaptability for specialty assignments.

Connectivity, Storage, and Battery Life

Both cameras rely on a single storage slot accommodating SD and Sony Memory Stick cards.

The RX100 III supports SDXC for high-speed, high-capacity cards, future-proofing storage needs.

Battery-wise, the RX100 III’s rated 320 shots and the A230’s 230 shots differ markedly, with the compact camera pulling more juice given its power-efficient sensor and screen technology.

Price-to-Performance: Which Delivers Value?

At launch, the A230 commanded roughly $570; the RX100 III about $750. Considering the RX100 III’s newer tech, higher resolution, video, and portability, the price premium is justified for casual to enthusiast users.

However, for beginners or those invested in interchangeable lenses (which form part of the $570 baseline), the A230 provides a DSLR experience unmatched by compact rivals.
