Olympus SP-100 vs Sony A37: A Hands-On Comparison for Photography Enthusiasts

Choosing between two cameras with distinct approaches - Olympus’s versatile bridge-style SP-100 and Sony’s entry-level DSLR-like A37 - may feel like comparing apples to oranges. But, having spent years evaluating hundreds of cameras in controlled tests as well as real-world scenarios, I’m here to guide you through the essential differences, strengths, and trade-offs of these two models. By unpacking their design philosophies, technical capabilities, and photographic performance across genres, you’ll discover which camera aligns best with your shooting style and professional aspirations.

First Impressions and Build: Handling and Ergonomics Matter

The Olympus SP-100 and Sony A37 differ markedly in body construction and handling. The SP-100 is a bridge camera styled to look like an SLR, boasting an enormous fixed zoom lens. In contrast, the Sony A37 is a compact DSLR-style interchangeable lens camera built on Sony’s Alpha legacy.

Size and Weight
The SP-100 weighs around 594g with dimensions of 122 x 91 x 133mm, notably bulkier due to its integrated 50x zoom lens. This creates a camera that feels substantial in hand but potentially front-heavy when zoomed out. The Sony A37 is lighter at about 506g and more compact (124 x 92 x 85mm), benefitting from a smaller footprint enabled by interchangeable lenses.

Ergonomics and Controls
Looking at their top layout:

The Sony’s DSLR-style design lends itself to a more traditional control setup with dedicated dials for exposure settings, while the Olympus integrates most control inputs sensitively but in a more simplified manner typical of bridge cameras. If you prefer a tactile, familiar grip with direct control access, the A37 feels more confident. The SP-100, meanwhile, favors ease of operation for those who want telephoto reach without frequently changing lenses.

Sensor Technology and Image Quality: The Heart of Photography

The sensor is where these cameras really diverge, setting the tone for photographic possibilities.

The Sony A37 boasts a large APS-C sized CMOS sensor (23.5 x 15.6 mm, 366.6 mm² sensor area) delivering 16MP resolution. Its sensor size allows for better light-gathering, low noise, and increased dynamic range - attributes crucial for professionals and enthusiasts prioritizing image quality.

The Olympus SP-100, in contrast, uses a much smaller 1/2.3-inch BSI-CMOS sensor (6.17 x 4.55 mm, 28.07 mm²), also at 16MP. This small sensor size inherently limits image quality, particularly in low light and fine detail extraction. The smaller sensor is the trade-off for an enormous zoom range at a consumer-friendly price.

Image Quality Observations
The A37’s APS-C sensor produces cleaner images with better detail, higher dynamic range, and remarkable color depth, ideal for landscape and portrait photography where nuance matters. The SP-100’s images, while decent for casual use or wildlife at a distance, show more noise at higher ISOs and softer detail, especially when pixel-peeping.

This difference in sensor size directly affects your artistic options: the Sony’s sensor enables selective focus and richer tonal gradients, while the Olympus excels at capturing distant subjects but with a shallower creative control palette.

LCD Screens and Viewfinders: Your Window to the World

Intuitive framing and review of images depend on effective displays and viewfinders.

The SP-100 features a fixed 3-inch TFT LCD with 460k-dot resolution - not the sharpest, but functional for framing and reviewing images. The A37 sports a smaller 2.6-inch tilting LCD at 230k dots. While lower resolution, the tilt feature provides ergonomic flexibility for shooting at tough angles.

Both cameras utilize electronic viewfinders (EVFs) but with noticeable differences: the SP-100 has a moderate 920k-dot EVF, whereas the Sony A37 employs a crisp 1.44 million-dot EVF offering full 100% frame coverage and 0.73x magnification. This makes the Sony’s viewfinder better suited for precise composition and manual focusing, crucial for demanding genres like macro or portraiture.

Autofocus Systems: Speed, Accuracy, and Subject Tracking

How fast and accurate a camera focuses can make or break your shooting experience.

The Sony A37 uses a hybrid phase-detection and contrast-detection autofocus system with 15 AF points including 3 cross-type sensors. This system provides swift, reliable focus locks and smooth continuous autofocus during burst shooting - especially valuable for sports and wildlife.

The Olympus SP-100 relies solely on contrast-detection AF, with unspecified focus point count but offering face detection and center-weighted AF. While decent for stationary subjects, it lacks the speed and precision of phase detection, sometimes struggling with moving targets.

Zoom Versatility vs Interchangeable Lenses: Which Fits Your Workflow?

A key distinction is the Olympus SP-100’s massive integrated 24-1200mm (50x zoom) lens versus Sony A37’s support for over 140 compatible Alpha-mount lenses (native + third-party).

The Olympus wins hands down if you crave a ready-to-shoot superzoom without fussing over lens acquisitions or swaps. This single lens covers ultra-wide to extreme telephoto, suitable for travel, wildlife observation, and casual use.

On the other hand, the Sony’s F1.4 to F22 aperture options and diverse lens ecosystem cater to more specialized needs - fast primes for portraits, macro lenses for close-ups, and rugged telephotos for sports. This flexibility lets you tailor optics to shoot genres requiring specific depth of field or image quality.

Burst Rates and Performance: Fast Enough to Catch the Action?

The SP-100 offers 7fps continuous shooting, slightly ahead of the Sony A37’s 6fps. Both are respectable for cameras in their class; however, the Sony’s superior autofocus during burst and quicker shutter speed topping out at 1/4000s versus 1/1700s in the Olympus provide an edge for freezing fast action.

Low Light and ISO Performance: When the Lights Go Down

Thanks to its larger sensor, the Sony A37 handles higher ISO settings far better. It has a native ISO range of 100-25600, delivering clean images even at ISO 1600 and usable results up to ISO 3200, with manageable noise reduction.

The Olympus SP-100’s native ISO ranges from 125 to 6400, but image quality declines sharply above ISO 800, showing visible noise and loss of detail, a typical constraint of small sensors.

If you plan nighttime, event, or indoor photography requiring high ISO, the A37 is clearly more capable.

Image Stabilization: Keeping Shots Crisp

Both cameras offer image stabilization, but with distinct approaches. The SP-100 has optical stabilization in the lens, optimized for its long zoom reach - vital for handheld telephoto shots.

The A37 employs sensor-shift stabilization (in-body), which benefits all mounted lenses and shines in low-light or macro shots. The Sony’s system, coupled with a richer lens lineup, provides versatile stabilization across most situations.

Video Capabilities: Not Just Still Photography

Both cameras support 1080p Full HD video, but the Sony A37 offers a richer codec array (MPEG-4, AVCHD, H.264) and frame rates up to 60fps, delivering sharper, smoother footage.

The SP-100 shoots 1080p at 60p and 30p in H.264, but limited manual video controls and fixed lens versatility restrict cinematic potential.

Both include microphone ports, an important feature for audio quality; neither has headphone monitoring.

Battery Life and Storage: Practical Considerations

Sony A37 wins comfortably with approximately 500 shots per charge using its NP-FW50 battery, ideal for day-long sessions. The Olympus SP-100 provides a respectable 330 shots, sufficient for travel or casual outings but less robust for extensive use.

Both cameras use a single SD card slot, with the Sony adding Memory Stick compatibility - a minor note, but nice for users invested in that ecosystem.
