We’ll also weave in sensor performance, ergonomics, autofocus behavior, and shooting handling, topped off by strategic image samples and evaluation metrics.

So, buckle in: this is more than a side-by-side spec check - it’s a journey across mid-2000s DSLR milestones and how these cameras stack up for modern-day buyers exploring vintage tools or those appreciating classic craftsmanship.

Form Factor and Handling: The Feel of the Vintage Workhorses

Before even locking lenses on subjects, a camera’s build and ergonomics shape nearly every shooting session. They’re tactile first impressions you’ll carry through dozens - sometimes hundreds - of hours behind the viewfinder.

Here, both cameras are mid-sized DSLRs but with distinct design philosophies. The Nikon D100 features a chunkier, more robust body, reflecting Nikon’s longstanding DSLR ergonomics lineage; the Samsung GX-1L is noticeably more compact and lighter, answering the demand for portability.

The Nikon weighs in at 780 grams - substantial but balanced - while the Samsung sits at a featherlight 570 grams. Dimensions also tell a story: the D100’s 144x116x81mm body houses a larger grip and more commanding presence; the GX-1L’s 125x93x66mm footprint feels nimble, appealing for street or travel photographers prioritizing mobility.

Top-down, the control layouts reveal Nikon’s typical DSLR design language - logical and tactile feedback with dedicated dials and buttons situated for quick access without removing your eye from the viewfinder. Samsung’s GX-1L opts for a stripped-back interface, which is clean but demands more menu diving for settings adjustment.

The Nikon’s pentaprism viewfinder offers 95% coverage at 0.53x magnification, which is decent for the era, whereas Samsung employs a pentamirror, slightly dimmer but with a marginally better 96% coverage and 0.57x magnification. Both offer optical clarity, with no electronic overlays - typical of DSLRs then.

Handling-wise, I found the Nikon’s heft gave more stability particularly during longer telephoto shoots, while Samsung’s GX-1L beckoned for spontaneous street capture with minimal bulk. Neither sported weather sealing, which is a serious consideration if your outdoor work demands durability.

Sensor and Image Quality: 6 Megapixels, But How Different?

With imaging sensors being the heart of any digital camera, beyond just megapixel count, sensor technology and size impact everything from resolution clarity to noise management.

Both the Nikon D100 and Samsung GX-1L use APS-C sized CCD sensors approximately 23.5x15.5mm in area. Nikon’s sensor measures 23.7x15.5mm (367.35mm²), while Samsung’s is virtually identical at 23.5x15.7mm (368.95mm²). Resolution-wise, both pack 6 megapixels (3008x2000 for Nikon; slightly taller 3008x2008 for Samsung) which was competitive for early 2000s DSLRs.

Examining the CCD technology and color filters, the Nikon’s sensor benefits from Nikon’s proprietary image processing heritage, yielding richer color reproduction and more pleasant skin tones - a vital factor in portraiture and wedding photography. The Samsung’s sensor, while competent, leans towards a cooler color balance with slightly less dynamic range in highlights.

ISO performance is a crucial realm where the cameras diverge: Nikon maxes out at ISO 1600, while Samsung pushes to ISO 3200. However, in practical testing, Samsung’s elevated ISO resulted in more noticeable noise and reduced detail retrieval, owing to limitations in their noise reduction algorithm and sensor technology of that time.

Both cameras feature an anti-aliasing filter, which helps combat moiré at the cost of minute sharpness loss - but this was typical in DSLRs until high-resolution sensors made it less necessary.

For raw shooters, both offer raw file support, with Nikon’s NEF files widely compatible with post-processing software, while Samsung’s SRW files demand more specialized or updated converters.

Autofocus and Shooting Speed: Getting the Moment Right (or Missing It)

The AF system on early DSLRs significantly influences usability, particularly for genres requiring quick focus acquisition like wildlife or sports photography.

The Nikon D100 employs a phase-detection autofocus system with contrast detection support in live view. Interestingly, it lacks eye or face detection and offers no continuous AF tracking, which feels archaic by modern standards but was par for the course in 2002. It supports multi-area AF and selective AF, but without dedicated AF area selection buttons, switching modes can be cumbersome.

Samsung’s GX-1L uses a five-point phase-detection AF system, a definite upgrade offering more focus points than Nikon’s unspecified count, though cross-type point details remain unknown. That said, Samsung lacks live view focus capabilities, limiting AF flexibility for composition.

Continuous shooting speed maxes out at 3 frames per second on both models - a modest figure by today’s standards, but serviceable for casual action shoots. Neither has silent shutter modes or advanced buffer management.

Subject tracking accuracy is limited in both cameras - both lack AF tracking and subject recognition, so success depends heavily on manual skill and experience. For precision hunting of wildlife or fast-paced sports, these cameras are underpowered but can still serve beginners effectively.

Image Review and Interface: Looking Over Your Shots

In-camera image evaluation is where many older models feel cramped. The Nikon’s 1.8-inch fixed LCD with just 118k pixels is sufficient for basic framing checks but lacks usability for detailed composition or histograms.

In contrast, Samsung’s GX-1L ups the ante with a larger 2.5-inch, 210k pixel fixed LCD, providing a crisper and more satisfying playback experience, especially in bright daylight shooting.

Neither camera features touch or articulating screens; live view is only available on Nikon D100, while Samsung forgoes it entirely. This limits flexibility when shooting from challenging angles.

Menus and button layouts are straightforward but not especially intuitive by modern standards. Neither has illuminated buttons, making working in low light a challenge - stash a headlamp or rely on memory.

Lens Ecosystem and Mounts: Choosing Your Optical Arsenal

Lens selection remains a critical factor for photographers. Nikon’s D100 uses the venerable Nikon F mount, which unlocks access to a legendary library exceeding 300 compatible lens options. This includes many affordable and professional-grade lenses, ranging from weather-sealed telephotos to sharp primes ideal for portrait and macro work.

Samsung’s GX-1L adopts the Pentax KAF mount, which supports a respectable 150+ lenses. While smaller, the Pentax ecosystem offers excellent optically stabilized lenses and attractive pricing. However, adapters to other lens systems can be limited and less reliable.

Given that both cameras have a 1.5x crop factor on APS-C, users must mentally adjust focal lengths to reach desired fields of view.

The Nikon F mount’s more extensive ecosystem means better access to lenses designed specifically for digital sensors, whereas Pentax lenses originally targeted film cameras, which impacts optimal sharpness and coatings.

Shooting Across Photography Genres: Where Each Camera Shines

Let’s move beyond specs and test each camera on real-world disciplines from portraits to landscape and beyond. This broad assessment stems from hands-on trials and anecdotes.

Portrait Photography

Nikon’s sensor and color science delivers more natural skin tones and smooth color gradation, crucial for portrait work. With decent bokeh potential when paired with fast Nikon primes (f/1.8 and faster), the D100 creates attractive subject separation.

Samsung’s color rendition tends to be cooler, making skin sometimes appear less flattering under studio tungsten lighting. The lack of eye detection AF isn’t a dealbreaker here but means a bit slower workflow.

Landscape Photography

Both cameras offer a similar resolution, which suffices for prints up to 11x14 inches comfortably. Nikon’s broader dynamic range handles scenes with high contrast better, preserving details in shadows and highlights.

Samsung’s slightly better viewfinder coverage aids composition here, but the lack of weather sealing on both is an issue for rugged landscape shooters.

Wildlife Photography

Neither camera boasts fast continuous shooting or extensive AF tracking, limiting their utility for fast-moving subjects. However, Nikon’s heavier body and F-mount access to long telephotos (400mm+) give it a slight edge.

Samsung’s 5-point AF provides marginally quicker focus on stationary birds but can struggle in dense foliage.

Sports Photography

Both share 3 fps burst - slow for sports but possible to nail moments with patience. Nikon’s better grip stability helps handheld shots, but neither camera excels in this demanding genre.

Street Photography

Samsung’s compactness and weight make it more discreet, suited for candid or street work. Nikon’s bulk adds presence but also a confidence boost for deliberate captures.

Macro Photography

Neither camera offers in-built image stabilization or macro-specific AF enhancements. However, with the right lenses, Nikon’s color fidelity and larger grip offer better control for close-up precision.

Night and Astro Photography

Limited ISO capabilities and absence of bulb shooting hampers specialized long-exposure work. Nikon’s ISO 1600 ceiling is usable with noise reduction, Samsung’s ISO 3200 possible but noisy.

Video Capabilities

Neither model supports video recording - a reflection of the era prior to mainstream DSLR video.

Travel Photography

Samsung’s smaller size and weight favor travel, but the larger lens ecosystem and grip ergonomics make Nikon appealing for those prioritizing image quality over portability.

Professional Workflows

Nikon’s raw files are widely supported in Adobe and Capture One, making post-production seamless. Samsung’s proprietary formats can burden workflows.

Connectivity, Storage, and Battery Life: The Unsung Nuts and Bolts

Both cameras lack modern wireless connections - the digital cameras’ age shows in this field. No Wi-Fi, Bluetooth, or GPS modules are present.

For storage, Nikon uses CompactFlash (Type I/II), a reliable early professional choice, while Samsung uses SD/MMC cards, which became industry standard. CF cards tend to be more durable but costlier.

Battery-wise, Samsung GX-1L runs on four AA batteries, a plus for travel when spares are easy to find. Nikon uses proprietary lithium-ion, offering longer life but needing dedicated chargers.
