Canon 100D vs Pentax K-50: An In-Depth Lens on Two Compact Entry-Level DSLRs

In the bustling world of interchangeable lens cameras, stretching your photography chops without breaking the bank often means diving into the entry-level DSLR waters. Today, we’re taking a long, hard look at two beloved models from 2013: the Canon EOS 100D (a.k.a. Rebel SL1) and the Pentax K-50. Both are compact, approachable DSLRs but with decidedly different design philosophies and capabilities. Having had both cameras in my hands and pushing them through their paces over several shoots, this comparison aims to arm you with practical, expert insight for your next gear decision.

We’ll unpack everything - from sensor tech, autofocus, and shooting experience, to specialized applications like wildlife or night photography. Buckle up for a balanced, real-world review that highlights strengths, admits flaws, and scores value for money by a guy who’s dealt with thousands of cameras. Whether you’re a casual enthusiast, serious hobbyist, or budget-conscious pro looking to add a backup body or starter kit, this one’s for you.

How Big Is Big? Handling and Ergonomics

Before any photos fire, the physical feel of a camera sets the tone for every shoot. Canon 100D’s biggest selling point is its shrunken DSLR dimensions - often marketed as the "world’s smallest APS-C DSLR." Measuring a compact 117 x 91 x 69 mm and weighing in at just 407 grams, it’s a cheat code for traveling light or slipping into tight street photography scenarios.

Contrast that with the more traditionally chunky Pentax K-50, which is 130 x 97 x 71 mm and weighs a noticeable 650 grams. It’s a bit beefier, but the extra heft adds a solid, reassuring grip that users with larger hands or thick gloves will appreciate.

I personally found the 100D’s small body charming, but if you’ve got thumbs like clubs, the Pentax K-50’s more generous control spacing and grip make longer shooting sessions less of a hand cramp fest. The K-50's weather resistance adds meaningful heft - more on that later - but it also feels rock solid in hand versus the 100D’s plastic-light chassis.

On the top-deck, the Pentax rocks a straightforward layout with clear dials - while Canon takes a more minimal-speed dial approach. Both cameras feature an easy-to-navigate cluster, but neither boasts illuminated buttons, which is a shame for low-light shooting.

For me, the 100D is perfect urban stealth, pocketable yet with manual controls close at hand. The K-50 is less discrete but feels like it could handle a hiking trip through the elements better. Your mileage will vary based on hand size and priorities.

Sensor and Image Quality: Where Pixels and Physics Meet

Both cameras pack APS-C sized sensors, but differences in resolution, sensor manufacturing, and image processing impact final image quality significantly.

Canon’s 100D carries an 18MP CMOS sensor sized 22.3 x 14.9 mm (332.27 mm²), while Pentax’s K-50 edges out with a lower resolution 16MP sensor but slightly larger at 23.7 x 15.7 mm (372.09 mm²). That marginally bigger surface area means the K-50’s pixels are larger, potentially translating to cleaner high ISO shots and better dynamic range.

DxOMark benchmarks back this up: The Pentax scores 79 overall compared to Canon’s 63, boasting better color depth (+1.9 bits) and dynamic range (+1.7 stops). In practical terms, the K-50 gathers more highlight and shadow detail and produces richer colors under varying lighting conditions.

Canon’s 100D maxes out ISO at 12,800 (expandable to 25,600), while the Pentax pushes a staggering 51,600 native ISO ceiling, although noise becomes intrusive early on. Still, Pentax’s "PRIME M" processor handles noise reduction impressively considering the era.

In real shoots - especially in landscapes and portraiture - I noted the K-50 files maintained smoother tonal transitions and superior highlight preservation compared to the 100D, which faces earlier clipping and tougher shadows. However, Canon’s sensor yields sharper files out of the box, partly thanks to a mild anti-aliasing filter.

If pixel-peeping or large print output is your game, the Canon’s higher res might tempt you, though at the expense of some noise control. The Pentax’s dynamic range advantage is crucial for nature and landscape photographers dealing with unforgiving skies and shadowed forests.

Viewing Your Shots: Display and Viewfinders

Engagement with your image happens largely through the viewfinder and rear display, and here the two cameras reveal some noteworthy distinctions.

The Canon 100D offers a 3-inch fixed screen with modest 1.04 million dots and a touchscreen interface. Its interface is a delight for live view focusing and navigating menus, a rarity in entry-level cameras of the time. The pentamirror optical viewfinder covers approximately 95% of the frame, which feels a tad restricted.

Pentax K-50 features a similarly sized 3-inch screen but at 921k dots resolution, notably without touchscreen support. However, its TFT LCD comes with brightness, color adjustments, and an anti-reflective coating - a boon for bright outdoor shooting.

Its optical viewfinder is a more professional pentaprism style covering 100% of the scene and 0.61x magnification, delivering a clear, accurate framing experience and bright image with less distortion.

In my experience, the Canon’s touchscreen live view makes focus-peaking and face-detection focus quicker, especially for macro and street shooting. But for classic DSLR purists favoring optical viewfinders, the Pentax K-50’s larger and more precise viewfinder is a definite draw.

Autofocus and Speed: Locking in the Action

When evaluating Autofocus (AF), things get interesting. The Canon 100D packs 9 AF points (one cross-type) while the Pentax K-50 has a slightly denser 11 points with 9 cross-type sensors. Cross-types matter because they can detect detail in both horizontal and vertical planes for improved precision.

Both cameras sport phase-detection AF systems and support Face Detection and continuous AF in live view, but Pentax’s more sophisticated AF array offers better coverage and tracking reliability, especially under mixed lighting.

In practice, for wildlife and sports where fast, reliable focus is king, the Canon’s modest 3 frames per second burst rate and simpler AF system lag behind Pentax’s 6 fps buffer. During a woodland bird shoot, the K-50 locked focus faster and tracked erratic bird flight more faithfully, while the 100D occasionally hunted or dropped focus during rapid movements.

Neither camera has eye or animal eye AF (a feature that debuted in later years), which means manual precision is your friend for tight portraits or close wildlife. But if autofocus speed and tracking rank high on your priority list, Pentax takes the trophy here.

Built Tough and Ready for Adventure: Weather Sealing and Durability

A major point distinguishing these two contenders is weather sealing. The Canon 100D offers no formal environmental sealing or protective gaskets. It’s best kept dry and treated gently.

The Pentax K-50, on the other hand, is one of the few entry-level DSLRs to boast weather resistance with over 80 weather seals guarding against dust and light rain (no submersible claims). This robustness makes the K-50 an ideal companion for off-trail hikes, misty landscapes, and adverse shooting conditions.

I personally took the K-50 into drizzle with zero fear of damage, while I’d approach the 100D with a plastic rain cover or camera bag shelter when bad weather rolled in.

If you’re an outdoor enthusiast who often shoots in rain, dust, or gritty urban environments, Pentax’s tougher build directly translates to peace of mind - and savings on repair bills down the line.

Lens Ecosystem: A Tale of Two Mounts

While bodies matter, lenses make or break your photography potential.

Canon’s EF and EF-S mount stands as a giant in the DSLR world with over 326 lenses available - from budget-friendly third-party primes to top-tier L-series professional glass. It’s a lens playground with constant updates, versatility, and excellent autofocus compatibility.

Pentax’s KAF2 mount offers a smaller but still respectable ecosystem of around 151 lenses, including legacy lenses from decades past. Pentax users enjoy native in-body sensor-shift image stabilization (IBIS), allowing almost any lens to benefit from stabilization irrespective of optical image stabilization availability.

Canon 100D lacks in-body image stabilization, meaning you’re dependent on stabilized lenses for shake reduction. The Pentax K-50’s sensor-shift stabilization is a significant practical advantage, especially when shooting handheld macro, telephoto, or video.

So, the choice narrows down to lens variety versus stabilization. Canon’s broader lens lineup with excellent autofocus lenses is perfect for those wanting mix-and-match glass, while Pentax users gain from the universality of IBIS - taking older manual lenses out of the closet and still getting sharp handheld shots.

Battery Life and Storage: Staying Powered and Saving Shots

Pentax K-50 modestly outlasts the Canon 100D with a rated 410 shots per charge compared to 380 shots on the 100D, both measured by CIPA standards. Not a massive gap, but keep in mind real-world figures often vary based on usage patterns such as flash, video, or live view.

Both cameras rely on proprietary rechargeable battery packs - the LP-E12 for Canon and D-LI109 for Pentax - offering decent longevity but always pack a spare for extended trips.

On storage, both support a single SD/SDHC/SDXC card slot with no dual slots or UHS-II support, typical for their class and vintage. Expect average buffer depths and moderate write speeds.

Specialties and Genre Performance in Practical Use

How do these cameras perform in various photographic genres? Here’s a breakdown, leveraging real-world tests and technical specs:

Portrait Photography

• Canon 100D: Crisp 18MP resolution and touch-based Eye Detection AF make skin tones pleasing and focusing on eyes straightforward. Limited autofocus points and lack of eye tracking means you’ll need to be deliberate with composition, but color rendition is pleasingly warm.

• Pentax K-50: Lower resolution but better dynamic range means flattering skin tones with more detail in shadows/highlights. Lacks touchscreen but has better overall AF coverage; IBIS aids in handheld portraits with softer backgrounds using stabilized lenses.

Landscape Photography

• Pentax K-50 shines here with superior dynamic range, better highlight recovery, and weather sealing, allowing photographers to shoot through moody dawns or light rain without worry.

• Canon’s 100D can deliver crisp landscapes but will struggle more with shadow noise and highlight clipping. Its more compact size is a plus for hikers wanting low bulk.

Wildlife and Sports Photography

Pentax’s faster continuous shooting (6fps vs 3fps) and superior AF tracking give it a clear edge for fast-moving subjects. The wider AF point coverage and larger maximum shutter speed (1/6000s vs 1/4000s) also provide more breathing room for capturing birds and athletes in bright light.

Canon’s 100D is more sluggish and struggles to maintain focus under erratic movement.

Street Photography

Canon’s 100D stealthy size and lighter weight are perfect street photography companions. Its quiet operation and touchscreen focus speed help capture spontaneous moments, though its limited AF points and 95% viewfinder coverage might frustrate some.

The Pentax K-50’s clunkier body and louder shutter sound are less suited for casual street snapping but stand firm in more deliberate shooting.

Macro Photography

Pentax’s in-body stabilization is a huge plus for macro shooters tackling handheld close-ups, reducing blur during high magnification work. Canon users rely on lens stabilization or tripods.

Both cameras lack focus bracketing/stacking, so layered focus requires manual technique.

Night and Astro Photography

Pentax ends up with better high ISO performance and dynamic range, vital for capturing stars and celestial landscapes with minimum noise and enhanced shadow detail. The K-50 also offers built-in intervalometer for timed exposures.

Canon 100D can function well but has more noise creeping in past ISO 3200, and time-lapse techniques need external timers.

Video

Both shoot Full HD 1080p up to 30 fps and 720p at 60fps. Canon’s touch UI and microphone port edge the video experience forward slightly. The Pentax lacks an external mic jack and HDMI output, limiting professional audio input and external monitor use.

Neither offers 4K, nor advanced video codecs, so both sit comfortably in beginner/enthusiast video realms.

Travel Photography

Canon’s small size, light weight, and touchscreen usability make the 100D a natural travel buddy. Pentax offers ruggedness and weather sealing, suited for adventurers less concerned about bulk.

Both cameras’ batteries and storage slots are similar.

Professional Applications

Neither camera is designed as a pro-level tool, but Pentax K-50’s robust build and superior image quality make it a respectable second body or entry-level workhorse for landscape photographers or outdoor photojournalists. Canon 100D is a friendly step-in for newcomers, school clubs, or casual pros focusing on portraits and travel images.

Connectivity and Extras

The 100D has Eye-Fi wireless card connectivity for image transfer, whereas Pentax leaves wireless tethering out entirely. The Canon’s HDMI output supports external displays, while Pentax omits it - meaning no easy clean HDMI feed or live streaming options on the K-50.

GPS modules are optional on both, with no built-in solutions.

Price and Value: What’s the Bottom Line?

Coming from the street prices of approximately $499 USD for the Canon 100D and $610 USD for the Pentax K-50 at launch, we see a classic trade-off: lighter & smaller or bigger & tougher.
