Nikon Coolpix S5100 vs Olympus SZ-30MR: A Hands-On Comparison for Enthusiasts and Professionals

Choosing between compact superzoom cameras often means balancing portability, zoom range, image quality, and usability. Today, we pit the Nikon Coolpix S5100 against the Olympus SZ-30MR, two small sensor compacts released about six months apart in 2010 and 2011, respectively. While both cameras target casual shooters stepping up from smartphones or entry-level compacts, our deep dive explores how each holds up across diverse photography styles and demands - with a nod to their technical underpinnings and real-world performance.

Having spent hundreds of hours in the field with similarly classed cameras, I’ll walk through their strengths and weaknesses from a professional perspective, aiming to satisfy enthusiasts and pros who want a trustworthy overview without the marketing fluff.

Form Factor and Handling: Pocketability vs Grip Comfort

Let’s start with the physical experience of these cameras. The Nikon S5100 is a compact through and through, with deceptively slim dimensions of 97 x 57 x 22 mm and a featherlight weight of 132g, making it excellent for discreet street shooting or travel.

Olympus SZ-30MR, meanwhile, is notably larger at 106 x 69 x 40 mm and weighs 226g, courtesy of its superzoom lens. Though still pocket-friendly, it feels more substantial and better balanced for long telephoto shots.

The Nikon’s smaller size brings less to hold on to, which might be a downside for those who crave tactile control or shoot extensively. The larger body of the Olympus allows for a more confident grip, critical when using its extreme 24x zoom, where camera shake is amplified.

Ergonomically, both cameras lack manual control rings or dials, standard for compacts at this level, but their button layouts differ - more on that shortly.

Control Layout and Interface Design

Top-down, these cameras clearly follow divergent design philosophies.

The Nikon keeps it minimal, with a smooth top plate, a small shutter release, and a power button flush with the body. This simplicity aids beginner users but impedes quick access to settings like ISO or flash modes.

Olympus, however, incorporates more dedicated buttons and a zoom toggle situated logically for one-handed operation. Its shutter button is larger and more responsive, which helped me nail shots of fast-moving subjects during testing.

Neither has touchscreens, but Olympus’ screen technology offers richer feedback, as we’ll see next.

Displays: Window Into Your Composition

The LCD panel is pivotal, especially given neither has an electronic viewfinder.

The Nikon S5100 sports a 2.7-inch fixed screen with 230k dots, subdued in brightness and contrast. Under daylight, it became challenging to discern details, adding frustration during outdoor shoots.

Olympus counters this with a bigger 3-inch TFT Hypercrystal III Color LCD boasting 460k dots, roughly double the resolution, delivering clearer, more vibrant images on the rear display.

I found myself trusting the Olympus display far more for critical framing and reviewing shot sharpness, especially at telephoto focal lengths where precise composition matters.

Sensor Design and Image Quality Fundamentals

Both cameras share a 1/2.3-inch sensor size (6.17 x 4.55 mm), common in compact models, but diverge significantly in sensor technology and resolution.

• Nikon S5100: Utilizes a 12MP CCD sensor paired with Nikon’s Expeed C2 processor.
• Olympus SZ-30MR: Upgrades to a 16MP CMOS sensor combined with TruePic III+ processing.

CCD sensors, like the Nikon’s, historically boast strong color rendition but consume more power and struggle under low light. CMOS sensors generally excel better with noise control and faster readout speeds, aiding video and burst performance.

The higher resolution of the Olympus supports larger print sizes and cropping flexibility, though increased megapixels on small sensors can elevate noise if not paired with robust noise reduction algorithms.

Practically, in well-lit environments, both cameras deliver decent JPEG output with good detail. However, in shadow recovery and high ISO images, Olympus pulls ahead with cleaner files and better dynamic range handling, likely thanks to its sensor and processing advantages.

Lens and Zoom: Versatility vs Speed

Nikon’s S5100 lenses offer a 28-140 mm (5x zoom) range at an aperture spanning f/2.7 to f/6.6. Olympus packs a breathtaking zoom with the SZ-30MR’s 25-600 mm (24x zoom) at f/3.0 to f/6.9.

This difference frames the distinct intended users - Nikon suits those favoring wide-angle to moderate telephoto range needed in everyday shooting, while Olympus targets wildlife, sports, and telephoto enthusiasts craving reach.

The Olympus’ immense zoom inevitably compromises maximum aperture, closing significantly at the long end compared to Nikon’s lens - meaning less light reaches the sensor and higher ISO settings may be necessary.

Both cameras include optical image stabilization:

• Nikon: Optical stabilization embedded in the lens assembly.
• Olympus: Sensor-shift stabilization, beneficial since it also assists with video and macro.

For close distances, Olympus impresses with a 1 cm macro focusing range, whereas Nikon starts at 2 cm. This subtle difference means Olympus slightly outperforms in macros, capturing fine details with greater ease.

Autofocus Performance: Speed, Accuracy, and Usability

Neither camera sports advanced autofocus systems found in DSLRs or mirrorless models, but relative performance matters for practical use.

The Nikon S5100 implements contrast-detection AF with face detection absent, limiting its tracking ability. Focus acquisition is average in good light but struggles noticeably in dim or fast-action scenarios. It also lacks continuous AF or tracking modes.

Olympus employs a more capable contrast-detection AF with face detection and tracking, improving acquisition speed and reliability - especially when capturing moving subjects like kids or pets. Olympus also offers multi-area AF, providing flexible focus point selection.

This difference manifests in burst rate too:

• Nikon does not specify continuous shooting speed, signaling spare burst capabilities.
• Olympus provides a 2 fps burst rate, modest by modern standards but useful for casual action sequences.

For critical fast autofocus in wildlife or sports photography, neither camera can seriously compete with dedicated long lenses or higher-tier cameras, but Olympus’ system offers a tangible advantage.

Image Stabilization: Minimizing Shake

Both cameras include effective stabilization systems for handheld shooting - handy given their zoom ranges.

Nikon’s optical stabilization works well at moderate telephoto, smoothing small jitters during travel or casual shooting. Olympus’ sensor-shift stabilization shines at longer focal lengths, notably at 600 mm equivalent, helping maintain sharper images when using the extended zoom.

During testing handheld at max zoom, Olympus delivered more consistently usable photos without the shutter speed needing to skyrocket, whereas Nikon’s shorter zoom meant less demand on stabilization.

Video Capabilities: Resolution, Formats, and Usefulness

For videographers, these cameras are modest options but represent a step above point-and-shoot base models.

Nikon S5100 records up to 1280 x 720 (HD) at 30 fps using Motion JPEG, the latter inflating file sizes and limiting video compression efficiency. No microphone or headphone inputs restrict audio control, and no stabilization mode specific to video is noted.

Olympus SZ-30MR improves with 1920 x 1080 Full HD at 30 fps recording in MPEG-4 format, producing more efficient files. It also adds HDMI output, useful for external monitoring or streaming setups.

Neither supports manual video controls or external mics, restricting professional video work. However, Olympus’ better sensor stabilization and codec make it preferable for casual video capture.
