When looking back at entry-level DSLRs from the mid-2000s, two cameras stand out for photographers stepping into digital SLR photography: Canon's EOS 350D (also known as the Digital Rebel XT) and Pentax's K100D Super. Both cameras offered strong value propositions in their day. But how do they hold up under professional scrutiny, and what does each bring to the table for today’s imaging enthusiasts?

Having logged countless field hours testing DSLRs across brands and generations, I share here a detailed, hands-on comparison of these two beloved models. This analysis goes beyond raw specifications to paint a vivid picture of their real-world usability, image quality, and suitability across photography genres. Whether you're a macro tinkerer, a budding wildlife hunter, or simply curious about these legendary models, join me as we unpack what the Canon 350D and Pentax K100D Super really offer.

First Impressions: Size, Build, and Handling

Physically, both cameras present as classic compact DSLRs - certainly bulky by today’s mirrorless standards, but typical for the era. The Canon 350D measures 127x94x64 mm and weighs 540g, sporting a slightly smaller footprint than the Pentax K100D Super at 129x91x71 mm and 646g.

The Pentax’s extra heft, partly due to its all-metal chassis and the inclusion of sensor-based image stabilization hardware, lends it a reassuring solidity. While the Canon feels lighter and more plastic-heavy, it remains comfortable to hold even during extended shoots thanks to a well-placed grip and balanced ergonomics.

The Canon edges out slightly in portability - preferring the 350D for travel or street shooters who value a lighter kit. Pentax favors durability and in-body stabilization, which we’ll explore further.

Control Layout and User Interface: Where Form Meets Function

Peering down at the top decks, the Canon 350D and Pentax K100D Super share many standard DSLR control traits, but their design philosophies subtly diverge.

The 350D’s top plate is straightforward with a mode dial offering PASM exposure modes, integrated power switch, and a traditional dedicated dial for main adjustments. Its compact design and button placement favor quick one-handed operation - ideal for photographers who value intuitive, rapid controls in dynamic shoots.

Pentax introduces a slightly heavier control layout. The K100D Super includes a dedicated exposure compensation dial, a top LCD panel for quick info glance, and a shutter speed dial - catering more to seasoned enthusiasts who prefer tactile controls over menu juggling. While Pentax’s approach might feel verbose to beginners, it offers more granular manual control with less reliance on submenus.

Both cameras omit live view and touchscreen functionality - typical for their generation but a consideration for those used to modern conveniences.

Sensors and Image Quality: The Heart of the Matter

At the core, the Canon 350D employs an 8.0-megapixel APS-C CMOS sensor sized 22.2 x 14.8 mm with a 1.6x crop factor, whereas the Pentax K100D Super uses a slightly larger 6.1-megapixel APS-C CCD sensor at 23.5 x 15.7 mm, sporting a 1.5x crop factor.

From a technical perspective, Canon’s CMOS sensor boasts greater resolution and better low-light sensitivity, with a max native ISO of 1600 compared to Pentax’s ISO 3200 ceiling (starting at ISO 200). Yet, in real-world tests, the Canon delivers punchier images with superior dynamic range - boasting approximately 10.8 EV versus Pentax’s respectable but narrower tonal latitude.

Color depth sits favorably on Canon’s side at roughly 21.8 bits, delivering vibrant hues and finely rendered skin tones, which will please portrait shooters and wedding photographers alike.

Pentax’s sensor, while older CCD technology, provides pleasing color rendition too, especially in daylight, and arguably has less rolling shutter due to hardware design differences. However, noise control at high ISO falls behind the Canon’s CMOS.

Both cameras apply anti-aliasing filters to combat moiré, but this contributes slightly to softness in the Pentax’s images, a tradeoff for fewer color artifacts.

The Screen and Viewfinder: Composition and Feedback Tools

Turning to image composition and review, the Canon 350D sports a tiny 1.8-inch fixed LCD with 115k dots resolution, while the Pentax K100D Super upgrades this experience with a 2.5-inch fixed LCD at 210k dots - almost double the size and clarity.

If you frequently rely on LCD playback or menu navigation, Pentax’s screen clearly enhances usability. The difference is striking when zooming to check focus or exposure in the field.

Both DSLRs rely on optical pentamirror viewfinders with roughly 95-96% frame coverage. Pentax edges out slightly with 0.57x magnification over Canon’s 0.5x, allowing for more immersive framing, critical in action or wildlife shooting where precise composition matters.

Keep in mind, neither offers electronic viewfinders or live view, so reliance on traditional optical framing and autofocus predominates. For beginners accustomed to smartphone LCDs, this may feel like a throwback.

Autofocus and Burst Shooting: Where Speed Counts

Canon and Pentax both utilize phase-detection autofocus systems with 7 points (Canon) and 11 points (Pentax). Although Pentax has more focus points, both cameras provide only basic AF area selection with no face or tracking detection.

In practical shooting, the Canon autofocus system is marginally faster and more responsive, especially in low light, allowing for quicker lock and less hunting. However, Pentax’s greater number of AF points can benefit recomposing and framing in still subjects.

Burst rates equalize at 3 fps, which is sluggish by today’s standards but typical for entry-level DSLRs of the era. For wildlife or sports photographers prioritizing fast action capture, neither camera excels; however, Canon’s buffering seems more robust, handling JPEG and RAW sequences without choking.

Lens Ecosystems and Compatibility: Choosing Your Glass

Canon’s EF/EF-S mount has historically boasted one of the largest lens selections, currently numbering over 320 compatible models covering everything from affordable kit zooms to top-tier professional glass.

Pentax’s KAF2 mount supports fewer lenses - approximately 150 - still sufficient for beginners but with less third-party support, fewer new lenses produced, and limited telephoto options. However, vintage K-mount lenses offer a sizable legacy selection, appealing to experimental shooters and collectors.

The Canon system benefitted from aggressive marketing and third-party adoption around 2005-2007, which helped it dominate in flexibility and future-proofing compared to Pentax’s more niche appeal.

Image Stabilization: An Essential Differentiator

Pentax K100D Super includes sensor-shift image stabilization, a tremendous advantage for handheld shooters, especially at slower shutter speeds or when using legacy lenses that lack stabilization.

Canon 350D offers no in-body stabilization, relying on lens-based IS where available. This restricts steady shooting performance to stabilized lenses, adding cost.

If you prioritize sharp handheld shooting in dim conditions, macro, or telephoto work, Pentax’s in-body IS is a compelling reason to choose the K100D Super despite its lower resolution sensor.

Battery and Storage: Practical Considerations

Battery life is a critical yet often overlooked factor. The Canon 350D uses a proprietary lithium-ion battery, offering decent endurance per charge but requiring purchase of spares to guarantee uninterrupted shooting during travel.

Pentax K100D Super runs on 4 x AA batteries - convenient in that replacements are globally available, albeit with weight penalties. This can be a lifesaver on trips to remote locations where charging options are scarce.

Storage-wise, Canon adopts CompactFlash cards, once the professional standard but now rare and expensive. Pentax uses SD/SDHC cards, which remain more commonplace and economical, simplifying media management.
