Samsung PL120 vs Sony RX100 IV: A Hands-On Camera Face-Off for Every Photographer

When it comes to choosing a camera, the options can be dizzying. Two models from very different generations and market segments - the budget-friendly Samsung PL120 ultracompact and the advanced Sony Cyber-shot RX100 IV large sensor compact - offer quite contrasting feature sets. I’ve spent hundreds of hours testing cameras to find how these two stack up in practical, real-world photography.

Whether you’re an enthusiast contemplating your next carry-everywhere shooter or a pro looking for a versatile compact backup, this detailed comparison will illuminate the strengths, weaknesses, and best use cases for each.

Pocket-Sized Rivalry: A Tale of Two Bodies

First impressions matter, and that often starts with how a camera feels and fits in your hands - and pockets.

The Samsung PL120 is ultra-compact to an extreme degree. With physical dimensions measuring 94 x 54 x 19 mm, it practically disappears in a jacket pocket - no clubs for your thumbs here. Its tiny 2.7-inch fixed LCD provides simple framing and menu navigation but lacks any touchscreen or tilting functionality, reflecting its budget-friendly and entry-level approach.

In contrast, the Sony RX100 IV measures a beefier 102 x 58 x 41 mm but still fits snugly into large pockets or camera bags. Its magnesium alloy body contributes to a relatively hefty 298 grams, signaling robust build quality for a compact. The 3-inch tilting LCD with 1229k-dot resolution offers much sharper live view and framing precision. Plus, the built-in 2359-dot electronic viewfinder (EVF) magnifies scenes with 100% coverage - perfect for bright outdoor shooting.

This difference in size and ergonomics is essential because it shapes how you’ll handle shooting across disciplines.

Both models lack environmental sealing, so neither invites abuse in rain or dusty conditions without extra protection.

Sensor Showdown: Size, Type, and Image Quality

At the heart of a camera lies its sensor, dictating resolution, dynamic range, ISO performance, and overall image quality. It’s here that these two diverge dramatically.

Samsung’s PL120 packs a modest 1/2.3-inch CCD sensor measuring about 6.16 x 4.62 mm (28.46 mm² area) with 14 megapixels. That sensor type was common in early 2010s compacts and is fine for casual snapshots but generally lags behind modern CMOS sensors in dynamic range and high ISO noise.

Sony’s RX100 IV, on the other hand, sports a larger 1-inch BSI-CMOS sensor (13.2 x 8.8 mm, 116.16 mm²), packing 20 megapixels. This sensor boasts an advanced backside illumination (BSI) design for improved light gathering, better dynamic range, and superior low-light sensitivity.

According to DxOMark scores, Sony’s RX100 IV outperforms in three critical areas:

• Color depth: 22.9 bits vs. untested Samsung
• Dynamic range: 12.6 EV vs. untested Samsung
• Low-light ISO: 562 vs. untested Samsung

This translates to richer, more nuanced colors, finer gradations between shadows and highlights, and cleaner images at higher ISO - indispensable for real-world photography challenges.

For portrait or landscape work demanding image fidelity, the RX100 IV’s sensor is in a whole other league.

UI and Controls: Buttons, Screens, and Shooting Experience

Switching attention to the user interface, it’s clear Samsung’s PL120 is designed with simplicity and casual users in mind. No manual focus, no aperture or shutter priority, not even exposure compensation. The menus are basic, and the lack of touchscreen means button mashing to navigate settings.

The 230k-dot LCD is serviceable but uninspiring. You get no electronic viewfinder, so bright daylight framing can be tricky.

Sony’s RX100 IV features manual focus, shutter priority, aperture priority, and full manual exposure modes - you name it. A customizable control ring around the lens adds tactile precision, while dedicated dials give quick access to crucial settings like exposure compensation. The 3-inch tilting screen is bright and detailed, though it lacks touchscreen. The high-res EVF comes in handy for critical framing and reduces eye strain.

Take a peek from above to see how their layouts reflect these priorities.

For photographers who crave creative control, the RX100 IV’s UIs and clubs-for-thumbs controls make the PL120 feel like a toy.

Autofocus Systems: Speed, Accuracy, and Tracking

A camera’s autofocus (AF) performance often makes or breaks real-world usability, especially for fast action, wildlife, or street photography.

The PL120 has no dedicated AF system worthy of the name - no contrast or phase detection autofocus, no tracking, no face detection, no continuous AF. In my hands-on use, focus hunting is frequent, and manual focus is nonexistent.

By contrast, Sony’s RX100 IV shines with a hybrid AF system featuring 25 focus points, including contrast detection, face detection, AF tracking, and continuous AF. During my burst shooting tests, it locks focus quickly and tracks subjects admirably - even in lower light. It’s responsive enough for casual wildlife snaps, street scenes, and even amateur sports.

This makes the RX100 IV infinitely more flexible and reliable when nail-biting decisive moments demand sharp focus.

Lens Details: Versatility and Optical Quality

With fixed-lens compacts, the lens is as important as the sensor for image impact. Here the RX100 IV continues to dominate.

Samsung’s PL120 focal length and aperture details are limited, but the 5.8x zoom suggests a focal length equivalent to roughly 35-203mm. Without aperture info or image stabilization, expect performance to be average with soft corners and less ideal for low-light or bokeh.

Sony’s RX100 IV has a fast 24–70mm (2.9x zoom) lens with a bright f/1.8 to f/2.8 aperture range. Optical image stabilization mitigates hand shake, and the macro capability focusing to 5 cm enables close-up creativity.

This combination equips RX100 IV users for wide-angle landscapes, portraits with pleasing background blur, and nimble telephoto shots.
