Samsung PL120 vs Sony A37: Which Camera Matches Your Photography Ambitions?

In the world of digital photography, choosing the right camera can be as daunting as mastering the craft itself. Over my 15 years as a camera tester and professional photographer, I've handled thousands of models, from barebones compacts to pro-grade beasts. Today, I’m putting two very different cameras side-by-side: the Samsung PL120, a slim ultracompact camera released in early 2011, and the Sony A37, an entry-level DSLR from 2012 featuring the translucent mirror tech Sony calls SLT.

These cameras couldn’t be more different in design, technology, and target user. Yet, each has its merits depending on your style, budget, and photographic aspirations. I’ve spent substantial hands-on time with both, testing them in varied shooting environments - from portrait studios and wildlife hides to urban street scenes and hiking trails at dawn.

Let’s unpack their strengths and shortcomings to help you determine which might be the better companion for your photography journey.

First Impressions and Ergonomics: Pocketable Convenience vs DSLR Handling

The Samsung PL120 immediately strikes you with its sleek, minimal footprint - it's an ultracompact designed to slip easily into a pocket or small bag. Measuring just 94x54x19 mm, it’s a perfect companion for casual shooting trips or everyday carry when you want discrete convenience.

In contrast, the Sony A37 is a compact SLR-style camera, notably larger and heavier at 124x92x85 mm and 506 grams body-only weight. It has the bulk and heft of a traditional DSLR, offering a grip and physical control layout that instinctively appeal to enthusiasts and those upgrading from older models.

From personal experience, the A37’s tactile buttons and dials make manual exposure adjustments and focus mode switches quick and precise even under pressure - ideal for learning photographers wanting deeper control. The PL120, however, lacks manual controls entirely; it's targetted for point-and-shoot simplicity.

Sensor and Image Quality: The Heart of the Matter

The Samsung PL120 uses a small 1/2.3" CCD sensor with 14-megapixel resolution - fairly standard for compact cameras of its era. On the other hand, the Sony A37 boasts a much larger APS-C CMOS sensor (23.5x15.6mm), commonly found in DSLRs, packing 16 megapixels.

From field testing, the larger sensor fundamentally provides the A37 with better image quality, especially in low light and high dynamic range scenes. The increased sensor area captures more light, resulting in cleaner images with greater tonal gradation and finer detail. The PL120’s small sensor tends to struggle as ISO climbs above 800, introducing noticeable noise and softer detail. It's adequate in bright daylight but noticeably limited once shadows deepen or scene contrast spikes.

With the A37, I encountered beautiful color rendition and excellent shadow detail even in mixed lighting. The dynamic range rating of 12.9 EV (as per DxO tests) translates to real-world prints with rich gradations and less clipping - critical for landscape and portrait work.

Display and Viewfinder: Composing Your Shot

The PL120 features a fixed 2.7-inch LCD screen with 230k-dot resolution - typical of entry-level compacts but small by today’s standards. It lacks touch capability, making menu navigation somewhat slower. Also, there is no electronic or optical viewfinder.

The Sony A37 has a slightly smaller 2.6-inch tilting LCD with similar resolution but makes up for it with a high-resolution (1440k-dot), 100% coverage electronic viewfinder (EVF) using Sony’s translucent mirror system.

In practical use, the A37’s EVF is a game changer - offering a clear, real-time preview of exposure, white balance, and focus before you press the shutter. For bright outdoor shooting and precise manual focusing, this is invaluable. The tilting screen adds compositional flexibility for low and high-angle shots.

The PL120’s lack of viewfinder makes sunlight viewing tricky, forcing reliance on the LCD, which can be hard to see and drain battery quickly.

Autofocus and Shooting Speed: From Leisurely to Action-Packed

The Samsung PL120 doesn’t offer any autofocus modes beyond basic contrast detection, lacking face or eye detection, continuous autofocus, or tracking. This makes it better suited for static scenes and casual snapshots where speed and accuracy aren't critical.

The Sony A37 features a 15-point phase-detection AF system with 3 cross-type sensors, face detection, and contrast detection for live view. It offers single, continuous, and tracking AF modes, delivering faster and more accurate focusing for both stills and video.

The burst mode on the A37 maxes at 6 fps, a respectable speed for entry-level DSLRs and perfect for moderate action, sports, or wildlife.

In real-world sessions, I found the A37 locks focus promptly on eyes and faces, handling erratic movement noticeably better than the PL120’s laggy focus behavior.

Lens Ecosystem and Versatility: Fixed vs Expandable

One of the biggest distinctions is the lens system. The Samsung PL120 sports a fixed lens with a 5.8x optical zoom. Unfortunately, Samsung doesn’t provide exact focal lengths, but this zoom range is moderate, limiting compositional flexibility.

The Sony A37 accepts all Sony/Minolta Alpha mount lenses - an extensive ecosystem that currently includes over 140 lenses ranging from ultra-wide primes and macro optics to super telephoto zooms. This opens the door to creative growth across every photography discipline.

Through my testing, I primarily used the Sony A37 with Sony’s 18-55mm kit lens and a 70-300mm telephoto zoom, which performed admirably for portraits and distant wildlife. The sensor-based image stabilization also provides steadiness lens-to-lens, enhancing hand-held sharpness.

Build Quality and Weather Resistance

Neither camera offers weather sealing or ruggedized construction, typical for their respective market segments and price points. The PL120’s light plastic body is prone to occasional flexing, suitable mostly for gentle use. The A37’s polycarbonate body is sturdier with a more comfortable grip, but still not designed for professional outdoor abuse.

Battery Life and Storage

The Samsung PL120 lacks detailed battery life data, but my hands-on use showed it requires frequent recharging or battery swaps during longer outings.

The Sony A37, running on the NP-FW50 battery, provides robust endurance - with around 500 shots per charge, which is solid for DSLRs. Storage-wise, it supports SD, SDHC, and SDXC cards, plus Memory Stick Duo formats, ensuring ample compatibility and capacity for photo and video workflows.

Connectivity and Extras

Connectivity is minimal on both cameras, with the PL120 having no USB, HDMI, wireless, or Bluetooth functionality.

The Sony A37 offers USB 2.0, HDMI output, and Eye-Fi support for WiFi-enabled memory cards, facilitating easier image transfer and playback on TVs or computers.

Video Capabilities: HD Meets SLT

Video is a notable advantage of the Sony A37. It records Full HD 1080p at up to 60fps with AVCHD and MPEG-4 formats, supporting external microphones via a dedicated port. The sensor-based stabilization aids handheld video smoothness.

The PL120 shoots only 720p HD video at 30fps with limited codec options and no external audio support.

For those who want decent video alongside stills, the A37’s offering is far more versatile and professional-grade.

Real-World Photography Tests: Strengths and Limitations

Below I share my observations across different genres, reflecting practical shooting conditions.

Portraits and Skin Tones

The Sony A37’s larger sensor and color depth deliver smooth, lifelike skin tones and gentle bokeh, especially when paired with fast prime lenses. Its face detection autofocus reliably locks and tracks subjects’ eyes - a must-have for sharp portraits.

The Samsung PL120 lacks face or eye detection, and the small sensor produces flatter tones with less subject separation, limiting portrait quality mostly to casual snapshots.

Landscapes and Outdoor Scenes

Dynamic range and resolution are vital here. The A37 shines with wide tonal range, high resolution, and the ability to swap in wide-angle lenses. The 16MP APS-C sensor provides ample detail for large prints or cropping.

The PL120’s sensor confines the quality, and its lens is less adaptable for expansive landscapes. Expect more noise in shadowy areas and less color fidelity.

Wildlife and Sports

The A37’s fast continuous autofocus and 6 fps burst rate, combined with customizable lenses, make it apt for moderate wildlife and sports shooting. Its optical viewfinder (implemented electronically here) offers quick, flicker-free viewing to track fast action.

The PL120, with slow autofocus and no continuous shooting, is ill-suited for action or moving wildlife.

Street and Travel Photography

Here is where the PL120’s size and simplicity appeal. Its compactness and quiet operation make it unobtrusive for candid street shooting. Battery life and autofocus limitations mean shorter sessions and more reliance on controlled light.

The A37 is larger but still fairly portable for travel. Its weather sealing absence means caution in wet environments. Its touchscreen-free interface may slow quick street shots, but precise focus and image quality make the tradeoff worthwhile.

Macro and Close-up

Neither model specializes in macro, but the A37’s lens interchangeability wins here. With appropriate macro lenses, it delivers high-resolution detail and focus control.

Night and Astro

The Sony A37’s superior ISO range (100 to 25,600), noise performance, and manual control support long exposures and astrophotography better than the PL120’s limited ISO ceiling and exposure options.

Professional Use and Workflow

The A37’s ability to shoot RAW is a standout for post-processing control, making it suitable for hobbyists progressing toward professional workflows.

In contrast, the PL120 shoots only JPEGs, restricting image editing flexibility.
