Canon EOS 40D vs Canon EOS Rebel T6: A Deep Dive into Two DSLR Generations

When comparing cameras nearly a decade apart like the Canon EOS 40D (2007) and Canon EOS Rebel T6 / EOS 1300D (2016), we're not just looking at specs on a sheet - we’re examining how photographic tools evolve across eras to meet changing user demands and technology availability. Having tested thousands of DSLRs across genres extensively, I find this a fascinating comparison illustrating shifts in sensor technology, ergonomics, autofocus, and usability for enthusiasts and entry-level shooters.

In this article, we’ll unpack these two from the ground up, considering their real-world photographic performance, build, and handling, alongside key technical analysis. By the end, you’ll have a clear picture of which Canon DSLR suits different photographers’ needs - a seasoned enthusiast revisiting the 40D or a beginner eyeing the budget-friendly T6.

Handling & Ergonomics: The Feel of a Decade in Design

One of the first things you notice is the physical difference: the Canon 40D is a stouter, heavier camera at 822g versus the lighter 485g T6. The 40D’s larger grip and more robust build better suit longer shooting sessions, weather resistance, and professional handling. It’s a mid-size SLR with a mid-2000s design ethos emphasizing durability and direct control.

The T6, as an entry-level DSLR, is compact and more plastic-bodied to reduce weight and cost. It aims at portability and ease of use for beginners or casual shooters. If you often hike or travel light, the T6’s small footprint may appeal more.

Ergonomics-wise, the 40D’s control layout is more extensive and tactile with dedicated buttons for ISO, metering mode, and drive mode, allowing quick adjustments without diving into menus. The T6 relies more on its menu system and fewer external controls, which can frustrate experienced photographers who like physical dials and buttons.

From my testing, the 40D’s bigger top panel and pronounced dials speed up workflow, while the T6’s simplicity benefits beginners overwhelmed by DSLR complexity but slows fast-paced shooting.

Viewfinders & LCD Screens: Optical Windows and Image Review

Both cameras use optical viewfinders - pentaprism (40D) versus pentamirror (T6). The 40D offers a brighter, higher-magnification viewfinder approximately 0.6x with 95% coverage, providing a superior shooting experience through the eyepiece. The T6’s viewfinder is smaller, dimmer (0.5x), also with 95% coverage, but less immersive, particularly in low light or when tracking moving subjects.

Examining rear LCD screens reveals an interesting story. The 40D sports a fixed 3” screen at just 230k dots - quite modest and somewhat grainy by modern standards. The T6 upgrades this with a 3” screen at 920k dots, meaning sharper, clearer image review and menu navigation, a huge benefit for users reviewing details on location or framing in Live View.

While neither has touchscreen functionality, the improved resolution on the T6 aids beginners and casual shooters navigating menus and reviewing images without needing a computer immediately.

Sensor Technology & Image Quality: The Heart of the Matter

Both cameras sport APS-C sized CMOS sensors, but their resolutions diverge: 10.1MP on the 40D vs 18.0MP on the T6. That’s nearly double the pixel count in the newer model, which generally translates to more detail for large prints or cropping flexibility.

Here’s where sensor technology evolution is critical. Although older, the 40D’s sensor was pioneering at release with respectable dynamic range and color depth for its time. The T6 benefits from advancements such as the DIGIC 4+ processor handling noise reduction and image processing, allowing it to push native ISO up to 6400 (expandable to 12800) compared to the 40D’s ISO ceiling of 1600 (boosted to 3200).

For usage like landscape or portraiture where dynamic range and color gradation matter, the T6 offers improvements despite being a budget camera - a tribute to nearly a decade’s progress in sensor fabrication.

Here’s a side-by-side visualization showing sensor dimensions and resolution differences:

During my field tests - photographing foliage transitions and skin tones - both cameras performed well. The 40D’s coloring felt more “organic” with less aggressive noise reduction, potentially favored by purists, while the T6 handled higher ISO scenes with cleaner shadows but sometimes softer detail at 100% view.

DxOMark overall scores confirm this: 64 for the 40D and slightly better 66 for the T6, mostly due to higher resolution and improved noise handling.

Autofocus Systems & Performance: Precision and Speed

Autofocus (AF) technology reflects the cameras’ generations and target audiences. The 40D uses 9 phase-detection AF points with no face or eye detection, while the T6 also has 9 points but includes face detection, live view AF, and continuous AF tracking improvements.

Testing AF under various conditions:

• Portraits: The 40D’s AF can focus accurately but tends to hunt slightly, especially in low light due to lack of face detection. The T6’s face-aware AF shines here, locking on eyes quickly and helping beginners achieve sharper portraits.

• Sports/Wildlife: The 40D’s maximum 6.5 fps burst rate outpaces the T6’s 3 fps, giving it an edge for action shooting. However, the 40D lacks sophisticated AF tracking, making keeping subjects in focus challenging as they move unpredictably.

• Live View & Video: The T6 offers live view AF with contrast detection, giving smoother operation for video recording and live framing. The 40D lacks this feature entirely.

Neither camera offers advanced animal eye AF or large cross-type AF coverage common in modern cameras, so the focus system suits controlled subjects best.

Build Quality & Weather Sealing: Ruggedness Tested

The 40D stands out for its partial weather sealing, which shields it against minor splashes and dust ingress - powerful reassurance for outdoors shooters and landscape photographers. Build quality feels solid, with a magnesium alloy body.

The T6 is plastic-bodied without weather sealing, consistent with its entry-level positioning. It’s more vulnerable to environmental hazards and less suited for demanding outdoor scenarios unless protected.

If you’re shooting in variable weather or dusty areas, the 40D’s build gives a professional edge.

Lens Ecosystem & Compatibility: Access to Glass

Both accept Canon EF and EF-S lenses, sharing a vast compatible range with over 300 lenses available.

This parity means lens selection isn’t a constraint for either camera, as both can use Canon’s extensive line from wide-angle primes to telephoto zooms, third-party lenses, and specialty glass like macro or tilt-shift optics.

Thus, your choice should focus more on your photographic style and budget than concerns about lens compatibility.

Battery Life & Storage: Practical Usage Considerations

The 40D impresses here with an official battery life of approximately 800 shots per charge, significantly outperforming the T6’s 500 shots. This longer endurance aligns with the 40D’s professional intent for extended shoots.

Storage-wise, the 40D uses Compact Flash cards while the T6 relies on SD/SDHC/SDXC cards - the latter being more accessible, cheaper, and easier to find today. CF cards are less common and more expensive but offer robust performance in professional workflows.

Overall, the T6’s smaller and lighter battery suits casual use, but serious enthusiasts will appreciate the 40D’s stamina.

Video Features: Lens on Moving Pictures

Video capabilities highlight clear generational divides. The 40D, released in 2007, offers no video recording.

Meanwhile, the T6 shoots 1080p Full HD video at 30fps and 24fps, plus 720p at 60fps, easily covering basic video needs. It records in MPEG-4/H.264 formats without microphone input, limiting audio control.

For hybrid shooters wanting both photos and casual video, the T6 is clearly superior. However, serious videographers will need external recorders or higher-tier bodies.
