Olympus VR-340 vs Sony SLT-A37: An Expert’s Deep Dive into Two Distinct 2012 Cameras

When comparing cameras as radically different as the Olympus VR-340, a small sensor compact, and the Sony SLT-A37, an entry-level DSLR, we’re engaging in more than a head-to-head spec match: we’re examining fundamentally different photographic philosophies. With over 15 years of hands-on testing, I’ve seen how sensor size, autofocus design, lens flexibility, and ergonomics dramatically shape both user experience and image quality.

Let’s unpack these two 2012 models with rigorous technical analysis, real-world performance insights, and candid commentary tailored for photographers hunting for their next tool - whether hobbyist or professional.

Getting a Feel for Them: Size, Handling, and Ergonomics

Right out of the gate, the cameras couldn’t be more physically and ergonomically distinct. The Olympus VR-340 is a pocket-friendly compact, weighing just 125 grams with diminutive dimensions of 96 x 57 x 19 mm. Conversely, the Sony A37 mirrors the heft and girth of an entry-level DSLR, tipping the scales at 506 grams and measuring 124 x 92 x 85 mm.

This size difference extends beyond weight: it greatly impacts how photographers interact with each model. The VR-340’s compactness makes it ideal for casual shooting, street photography, or travel where light packing is non-negotiable. However, its thin body limits grip comfort, especially over extended shoots or when using with a tripod.

The A37’s DSLR-style body is decidedly more robust. It offers substantial, well-contoured grips and an overall design built for controlled handling. Despite its larger profile, the ergonomics support professional postures during portraits, sports, or wildlife sessions - think of it as a more stable platform for longer lenses and prolonged burst shooting.

Looking closely at control layouts confirms their intended audiences. The Olympus VR-340 is simplicity itself - it lacks manual dials and features a largely automatic focus, exposure, and aperture setup. In contrast, the Sony A37 offers dedicated shutter speed, aperture priority, exposure compensation, and manual modes, laid out logically for quick access. This transparency empowers photographers who want creative control rather than point-and-shoot convenience.

Sensor Technology and Image Quality: Compact CCD vs APS-C CMOS

Here lies the most defining difference in image potential between these two cameras.

The Olympus VR-340 houses a small 1/2.3” CCD sensor measuring just 6.17 x 4.55 mm, with an area of 28.07 mm² and 16 megapixels. This tiny sensor - standard fare for compacts - restricts dynamic range, high ISO performance, and depth of field control, all crucial for demanding photography genres.

The Sony A37 packs an APS-C sized CMOS sensor with dimensions 23.5 x 15.6 mm, providing a sensor area of 366.6 mm² and 16 megapixels as well. This is approximately 13 times larger sensor area than the VR-340. It employs back-illuminated CMOS technology enhancing light sensitivity, allowing cleaner images at high ISO, wider dynamic range, and suitable DOF control for professional use.

Hands-on tests reinforce these numbers. The A37’s larger sensor yields far richer color depth (DxOMark scores: color depth ~23.3 bits vs untested for VR-340) and masterful tonal gradations across shadows and highlights. Noise at ISO 800 is minimal in the A37, whereas the VR-340 begins to degrade visibly beyond ISO 400. In low light, the A37 confidently shoots hand-held at higher ISO, while the VR-340 is often forced into slower shutter speeds due to limited sensor sensitivity.

Overall, the Sony’s sensor is a game-changer in portraits, landscapes, and more - any scenario demanding image quality. The compact’s sensor is adequate for casual snapshots, but professionals and serious enthusiasts will find it limited.

Working the Interface: Screens, Viewfinders, and Autofocus Systems

Both cameras offer live view, but their interfaces could not be more divergent.

The VR-340 features a fixed 3-inch 460k-dot TFT color LCD screen. Bright and sharp enough for casual framing, it lacks any touchscreen or tilt function, limiting flexibility for creative angles or menu navigation.

By comparison, the Sony A37 uses a smaller 2.6-inch, 230k-dot tilting LCD. While lower resolution, the tilt adds real-world utility for low-angle macro shots or odd street photography compositions. Moreover, the A37 includes a high-resolution (1440k dots) electronic viewfinder (EVF) covering 100% frame - a godsend for stable, accurate composition in bright light when LCDs can be washed out.

Autofocus is another critical area. The Olympus VR-340 relies solely on contrast-detection AF with a relatively unsophisticated system. It provides face detection but is limited in speed, tracking, and low-light sensitivity. Also, it offers no manual focus override, confining users to fully automatic operation.

The Sony A37 changes the game with a hybrid AF system featuring 15 phase-detection points plus contrast detection. While not top-of-the-line today, it rapidly focused even in low light, maintained impressive tracking during bursts at 6 fps, and supported selective AF point choice along with face detection.

Our tests clearly evidenced the Sony’s advantage in capturing moving subjects, pinpoint focusing for portraits, and macro work. The Olympus is better suited for still, well-lit scenes or casual snapshots.

Lens Ecosystem and Zoom Versatility

Lens flexibility separates beginner and compact cameras from DSLRs and mirrorless systems.

The Olympus VR-340’s 10x built-in lens offers a versatile 24-240mm equivalent focal range at F3.0-5.7 aperture - quite respectable for a compact. It includes basic optical image stabilization for reducing handshake blur.

Sony’s A37, featuring the Minolta Alpha mount, opens access to over 140 compatible lenses at launch, ranging from ultraspeed primes to super-telephotos and macro optics. The lens used depends on the shooter's choice, tailored to genre and aesthetics. Additionally, the A37 supports sensor-based stabilization for compatible lenses, increasing shooting flexibility.

While the Olympus’ lens serves as an all-in-one convenience, it can’t compete with the customizability or optical quality of prime or specialized lenses available for the Sony. For wildlife, sports, portraits, or macro photography requiring fast apertures or close focusing, the A37 lens ecosystem is vastly superior.
