Fujifilm JX370 vs. Fujifilm S4200: A Detailed Comparison for Enthusiasts and Pros

Choosing the right camera is never a trivial task, especially when it comes to balancing portability, versatility, and image quality. Fujifilm’s compact and superzoom models - the FinePix JX370 and the FinePix S4200 - offer compelling options for hobbyists and enthusiasts on modest budgets. To help you determine which fits your specific photography needs, I’ve tested both cameras extensively, examining their real-world performance, technical merits, and usability across multiple genres.

Whether you’re into casual portraits, travel, macro, or simply want a solid all-rounder, this comparison dives deep into their capabilities. I’ll walk you through everything from sensor tech and autofocus to ergonomics and shooting versatility, blending hands-on experience with objective analysis. Let’s get started.

First Impressions: Ergonomics and Handling

Before unpacking the specs or pixel counts, how a camera feels in your hands directly influences your shooting experience. The JX370 is a ultra-compact point-and-shoot, while the S4200 is a bulky, bridge-style superzoom. Let’s compare their size and design.

The JX370 is lightweight (124g) and pocketable with a sleek, minimal body measuring just 95x57x24 mm. No viewfinder or grip bump here - shotting is all about convenience. If you need a grab-and-go camera, this wins hands down.

In contrast, the S4200 weighs 543g and feels solid with an SLR-style body (118x81x100 mm), offering a substantial grip and tactile buttons. This camera demands its own bag but returns control and comfort for longer sessions or zoom-heavy shooting.

Another useful viewpoint is the control layout from above:

The S4200 has dedicated dials for shutter and aperture priority, manual exposure, and exposure compensation - a rarity at this price. The JX370 sticks to full auto and limited manual controls, targeting casual shooters prioritizing simplicity.

Ergonomics Summary

If portability and lightness top your list, the JX370 shines. If you want more control and a better grip during longer shoots or zoomed-in photos, the S4200 is more comfortable.

Sensor and Image Quality: Beyond the Megapixels

Both cameras share the same sensor size and resolution - a 1/2.3-inch CCD sensor with 14-megapixels. However, details matter beyond resolution.

The sensor area on each is the same (6.17x4.55 mm), and both use an anti-aliasing filter, which slightly softens fine detail to avoid moiré but can reduce sharpness. The fixed filter means neither camera is suited for critical microscope-level resolution but should hold up well for casual and social media prints.

Sensor Technology and Performance

The sensor technology hails from the early 2010s, fine for daylight and well-lit environments but with inherent weaknesses:

• Noise and ISO: Maximum native ISO caps at 1600 for the JX370 and 1600 (expandable to 6400) for the S4200, though image quality rapidly declines above ISO 800.
• Dynamic Range: Limited compared to modern CMOS sensors; highlights clip faster and shadows lose detail in challenging lighting.
• Color Rendition: Fujifilm’s color science provides pleasing, natural hues, a plus for portraits and landscapes.

Practically, the S4200’s ability to push ISO further and its generally better noise processing (due to a newer processor and firmware) offer a noticeable advantage in low light.

Image Quality Takeaway

• Both cameras deliver crisp images in bright light with accurate colors.
• The S4200 produces slightly cleaner images at higher ISO and more usable dynamic range.
• Neither supports RAW, so JPEG quality settings and in-camera processing are your limits.

For casual photography with good lighting, the sensor equality means you won’t find a huge difference. For anything more demanding - in shadows, indoors, or night shots - the S4200 edges ahead.

Autofocus and Performance: Speed Meets Accuracy

Autofocus can make or break an experience, especially for wildlife, sports, or street photography where decisive moments matter.

Both rely on contrast-detection AF systems but differ functionally.

Hands-on AF Experience

The JX370 has a simple AF system with a fixed center point. It’s fairly slow to lock focus, especially in low contrast or dim environments. Tracking subjects is unreliable, making it less suited for action or wildlife.

The S4200 improves this with multi-area autofocus and face detection, delivering faster locks and better tracking. Though still slow by today’s standards, I found it significantly more capable for everyday shooting, including portraits.

Continuous AF modes worked better on the S4200, enabling burst shooting of moving subjects with more success.

In low light, both cameras struggle, but the S4200’s AF system manages focus slightly better thanks to better algorithms and possibly firmware updates.

Lens and Zoom Capabilities: Field Flexibility Online

Tackling focal range:

• JX370: 28-140 mm (5x optical zoom), aperture F2.6 to F6.2
• S4200: 24-576 mm (24x optical zoom), aperture F3.1 to F5.9

The S4200 delivers a massive zoom range - equivalent to a pro telephoto in some cases - extending creative possibilities in wildlife or sports significantly.

The wider wide-angle on the S4200 (24 mm vs. 28 mm on the JX370) lends itself better to landscapes or tight spaces.

Macro Capabilities

• JX370 macro starts at 10cm minimum focusing distance.
• S4200 excels with a closer 2cm macro range, enabling detailed close-ups.

While neither lens is known for sharpness at extreme zoom, I found both decent within mid-zoom ranges.

Image Stabilization

The lack of stabilization on the JX370 is a major drawback at telephoto zooms, leading to blur on handheld shots.

The S4200 benefits from sensor-shift image stabilization, markedly helping in low light or zoomed shots, reducing reliance on tripods.

Viewing and Interface: Framing Your Shot

Both cameras rely on fixed TFT LCDs without touch.

The S4200’s large LCD and optional electronic viewfinder (EVF) offer much better framing flexibility in bright sunlight, a distinct advantage out in the field.

The JX370's screen is smaller and reflective, which can make composition outdoors tricky.

Interface-wise, the S4200 provides a traditional DSLR-like menu system with shortcut buttons, helping speed workflow. The JX370’s menu is more minimal but less intuitive for advanced settings absent on this camera anyway.

Real-World Photography Tests and Samples
