Hand Feel and Design: Small Body vs. Classic DSLR Build

One of the first noticeable differences is the body design and size. The Canon 100D was, at launch, the world’s smallest and lightest DSLR, weighing just 407 grams and measuring 117 x 91 x 69 mm. The 500D weighs 520 grams and is a bit bulkier at 129 x 98 x 62 mm.

• Canon 100D: Its compact size makes it extremely portable and easy to carry on travel or street shoots. This is a huge plus for photographers valuing discretion and comfort in handheld shooting.
• Canon 500D: While larger and heavier, it features a more robust grip that can provide better stability, especially with longer telephoto lenses often used in wildlife or sports.

If you prioritize ultimate portability without sacrificing DSLR controls, the 100D’s compact frame is ideal. However, for large hands or prolonged sessions, the 500D’s grip may be more comfortable.

The top plate layout reflects ergonomic priorities; the 100D’s modern button placement versus the more spacious 500D.

Control Layout and User Interface: Clear, Accessible, and Responsive

Looking at the control ergonomics through their top view:

• The 100D’s button layout is modernized, with an intuitive exposure compensation button and easy mode dial access, making it friendly for beginners and on-the-go adjustments.
• The 500D offers classic DSLRs' straightforward layout but lacks refinements such as illuminated buttons or a second control dial for faster parameter changes.

Neither includes a touchscreen interface beyond the 100D’s basic touch sensitivity on the fixed LCD. The 500D’s screen is purely tactile-free. While you won’t get advanced touch gestures or menu drilling, both cameras offer solid manual controls suitable for serious users willing to invest time learning DSLR operation.

Both cameras share an APS-C sensor size but differ in resolution and processor generation.

Sensor and Image Quality: The Heart of the Matter

Both the Canon 100D and 500D use an APS-C sized CMOS sensor with a 1.6x crop factor. Yet, their sensor resolutions and processors impact image detail and noise handling:

What does this mean in practice?

• The 100D’s higher resolution sensor (18 MP vs. 15 MP) offers more image detail, important for large prints and cropping flexibility.
• The 12,800 native ISO and 25,600 boosted ISO on the 100D far outpace the 500D’s 3,200/12,800, meaning low-light and night photography are better on the newer model.
• Despite a marginally lower dynamic range on the 100D, the difference is negligible in everyday shooting.

Our tests confirm that the 100D delivers slightly cleaner images at higher ISOs with less color noise, while both cameras produce vibrant, richly detailed photos in good light. For photographers focusing on portrait and landscape work requiring fine image quality, the 100D’s sensor has an edge.

LCD and Viewfinder: Composing Your Shots with Confidence

The Canon 100D includes a sharper and touch-sensitive LCD, enhancing usability over the 500D.

Both DSLRs boast a 3-inch LCD with roughly 1 million dots on the 100D and 920k dots on the 500D, improving brightness and detail in live view and playback. Unlike the 500D’s TFT panel, the 100D features touch sensitivity, allowing faster menu navigation and focus point selection during live view - an advantage for video shooters and street photographers wanting quick adjustments.

The optical viewfinders on both are pentamirror types with 95% frame coverage and 0.55x magnification. Though not as bright or precise as pentaprism viewfinders found in pro models, they are typical for entry-level DSLRs and provide clear framing with no lag, vital for action and sports photography.

Autofocus Systems: Speed and Accuracy in the Field

Autofocus (AF) performance is a make-or-break feature in real-world shooting, especially for moving subjects:

While both cameras have 9 AF points, the 100D offers more refined continuous AF tracking in live view and better face detection algorithms. This gives the 100D a significant advantage for wildlife, sports, and street photography where subjects move unpredictably.

The older 500D lacks effective AF tracking, requiring more manual focus intervention or careful pre-focusing. This is particularly noticeable in burst shooting or dynamic situations.

Burst Shooting and Buffer Depth: Capturing the Decisive Moment

Both cameras shoot at 3 frames per second (fps) continuous burst speed. This is sufficient for casual sports or wildlife work but will limit professionals capturing fast action.

The buffer size (how many shots you can take continuously before slowing) is limited on both, partly due to UHS-I SD cards and image processing capabilities. The 100D’s newer Digic 5 processor offers slightly faster clearing of buffers, but expect about 5-6 RAW shots before slowdown.

For sports enthusiasts requiring high frame rates (6+ fps), these models may feel restrictive, prompting consideration of more recent or prosumer models.

Video Performance: Basic Full HD for Content Creators

Video capabilities are similar but with important distinctions:

The 100D supports 30 fps Full HD and 60 fps 720p, making motion smoother and more versatile, especially for YouTubers or casual videographers. The presence of a microphone input on the 100D means better audio capture with external mics, which the 500D lacks.

Neither camera offers 4K recording or in-body stabilization, so a gimbal or stabilized lenses are necessary for professional video smoothness.

Build Quality and Weather Resistance: What to Expect

Neither camera features environmental sealing or ruggedized body components - they are typical entry-level DSLRs with plastic construction designed for everyday usage rather than extreme conditions.

• The 100D’s smaller body means slightly less robust handling for rough situations, but the modern design feels solid for lightweight field use.
• The 500D’s slightly larger frame provides a bit more hand coverage for stable shooting tripod setups.

Neither are recommended for heavy rain or dust without extra protection, although both handle normal outdoor shooting conditions well.

Lens Ecosystem and Compatibility: Your Creative Arsenal

Both cameras use Canon’s popular EF and EF-S mounts, with access to over 300 native lenses covering everything from wide-angle landscapes to super telephoto wildlife optics and macro lenses.

• This extensive lens support means you can tailor your system to your style - whether it’s a fast 50mm prime for portraits or a versatile 18-135mm zoom for travel.
• The 100D’s autofocus improvements pair well with newer lenses featuring USM motors and STM (stepping motor) technology for quieter, smoother focusing.

If you’re investing in a Canon lens system or upgrading from entry-level glass, both cameras integrate seamlessly.

Battery Life and Storage: How Long Can You Shoot?

While the 500D lasts longer per charge, the difference is marginal. You should carry spare batteries for day-long shooting sessions anyway, especially for video or burst mode shooting.

The 100D supports SDXC cards, allowing the use of higher capacity memory cards.

Connectivity and Extras: Staying Connected in the Digital Age

Both cameras offer basic Eye-Fi wireless SD card compatibility, allowing early wireless image transfer solutions but lack modern Wi-Fi, Bluetooth, or NFC connectivity.

• In practice, this means you may need tethering cables, card readers, or third-party Wi-Fi adapters for instant sharing.
• Both feature mini HDMI ports for external monitoring or playback.

For mobile-first creators, these limitations might encourage considering newer models with integrated wireless features.
