Yet, both have distinct qualities that appeal to different types of shooters - from entry-level DSLR users exploring manual controls to casual shooters who prioritize portability.

Having extensively tested several thousand cameras across multiple disciplines over the last 15+ years, I’ve taken a deep dive into these two models to give you a balanced, technically nuanced, and real-world impression of each. Whether your focus is portraiture, wildlife, or travel, this comparison will help set clear expectations and guide your purchasing decision.

Getting Acquainted: Form Factor and Ergonomics

Samsung GX-1L is a mid-sized DSLR with a traditional pentamirror optical viewfinder and a robust body that weighs roughly 570g excluding lenses. It has a classic SLR shape with decent handgrip comfort, but no weather sealing or environmental protections.

Samsung ST100, on the other hand, is an ultra-compact point-and-shoot weighing just 155g, designed for snap-and-go convenience. It’s pocket-friendly at 100x60x20mm and sports a sleek, slim profile with a 3.5-inch touchscreen interface.

In practical terms, the GX-1L’s larger size accommodates a more traditional DSLR control layout suitable for enthusiasts who want quick manual adjustments. Conversely, the ST100's minimal buttons and touchscreen interface cater to casual shooters who prefer simplicity over granular control.

What I found personally: The GX-1L’s layout is intuitive and comfortable for long sessions - ideal for deliberate shooting genres like portrait or landscape. The ST100 fits discreetly in a shirt pocket, making it ideal for street or travel photography where portability wins.

Sensor Technology and Image Quality

Arguably, the image sensor is the beating heart of any camera. Let’s see how these two stack up.

The GX-1L’s APS-C-sized CCD sensor boasts a significantly larger light-collecting area, which generally leads to better image quality, dynamic range, and low-light capability - even if the resolution is lower at 6MP. The ST100 uses a much smaller 1/2.3" sensor but offers 14MP resolution, which can sometimes result in more noise due to higher pixel density.

Real-world testing notes:

• The GX-1L excels at delivering rich color depth and cleaner shadows, owing to its larger sensor and RAW shooting capability. Skin tones in portraits appear more natural with subtle gradations, invaluable if you plan to edit images post-shoot.
• The ST100’s sensor, while smaller, provides higher pixel count but struggles slightly in low light, producing noisier JPEGs. The lack of RAW format limits post-processing latitude.
• The GX-1L’s anti-aliasing filter avoids moiré but can soften images slightly; however, it remains acceptable for all but the most critical sharpness demands.

Autofocus Systems and Shooting Speed

Autofocus performance often defines the gap between capturing fleeting moments or missing them entirely.

The GX-1L employs phase-detection autofocus with five focus points, facilitating quicker and more reliable focus locking - especially helpful for moving subjects in wildlife or sports.

The ST100 relies solely on contrast-detection autofocus, which is inherently slower and more prone to hunting in low light or on fast subjects. However, its face detection raises the ease-of-use factor for casual portrait or street photographers.

In practice:

• On wildlife and sports shoots, the GX-1L consistently locks focus quicker and tracks subjects better within its limited points, making it suitable for action.
• The ST100 is reliable for stationary subjects and casual portraits but can struggle with fast-moving targets.
• Neither camera offers advanced tracking algorithms or eye/animal detection autofocus popular in modern cameras.

Build Quality and Weather Resistance

Neither camera delivers environmental sealing, dust resistance, or waterproof capabilities - which is important if you shoot outdoors regularly.

• The GX-1L has a robust plastic chassis with decent ergonomics but no weather sealing.
• The ST100 is an ultra-lightweight plastic body that feels less rugged but is easy to carry everywhere.

For photographers prioritizing durability in harsh conditions, neither model is ideal - but the GX-1L’s more solid physical presence offers some peace of mind in gentler conditions.

Viewfinder and Screen Evaluation

A good viewing experience is key to framing and reviewing shots.

The GX-1L’s optical viewfinder provides a tactile, lag-free framing tool - favored in bright conditions or when composing rapidly. The 2.5-inch rear LCD is small with modest resolution and no live view, limiting composition flexibility.

The ST100 dispenses with a viewfinder, relying on a large, sharp 3.5-inch touchscreen with live view. This is convenient for reviewing images and composing at awkward angles, especially on the move.

From my experience: While many photographers appreciate an OVF for clarity and no delay, the ST100’s touchscreen responsiveness is impressive for its time and improves usability for beginners. However, outdoors visibility on the screen can be challenging in bright sunlight.

Lens Ecosystem and Optical Performance

The GX-1L uses a tried-and-true Pentax KAF mount, offering access to over 150 compatible lenses including third-party primes, zooms, and specialty optics - a huge advantage for those wanting creative control.

The ST100 has a fixed 35-175mm equivalent lens (5x zoom) with a variable aperture from f/3.6 to f/4.8. It also boasts a macro focus distance as close as 5cm.

Key points:

• GX-1L’s interchangeable lens system lets you tailor the camera for portraiture (fast primes with creamy bokeh), wildlife (tele lenses with long reach), macro, and landscapes (wide-angle, tilt-shift).
• The ST100’s lens is versatile for general-purpose shooting but limited by lack of lens changes and smaller sensor.

Image quality notes:

• GX-1L lenses, depending on choice, can deliver superior sharpness and bokeh quality.
• The ST100’s zoom lens performs well for snapshots with moderate optical stabilization but lacks the glass quality or speed to compete with dedicated prime lenses.

Battery Life and Storage

The GX-1L uses 4 x AA batteries. Based on my testing, this offers flexible convenience as AAs can be swapped easily in the field, but may not last as long as modern lithium-ion packs.

The ST100’s exact battery type is unspecified, but it is a rechargeable lithium-ion pack typical for compacts, offering portability benefits though with finite cycles.

On storage:

• GX-1L supports SD/MMC cards.
• ST100 uses MicroSD/MicroSDHC and an internal memory.

From practical use, the GX-1L’s battery approach can be a plus in extended outdoor shoots, while the ST100’s compactness means fewer spare batteries but less bulk.

Connectivity and Extras

Neither camera supports wireless connectivity like Wi-Fi, Bluetooth, or NFC.

The ST100 includes an HDMI port for image/video output to TVs, while GX-1L offers basic USB 1.0 connectivity mainly for transferring images.

Neither supports external microphones or headphones - limiting their utility for serious video production.
