In the ever-evolving world of digital photography, some cameras become iconic for their balance of performance, price, and usability. Canon’s EOS 40D and EOS 700D (also known as the Rebel T5i in some markets) both fall into this category, although they hail from different eras of DSLR development. Released six years apart, the 40D in 2007 and the 700D in 2013, these models cater to different segments and photographic needs. Yet, each holds a distinct appeal for enthusiasts and even certain professionals today.

Having personally tested thousands of cameras over the last 15 years, including these two models extensively, this article will walk you through a thorough comparison, layering technical expertise with real-world insights. Whether you're juggling a modest budget, hunting for the best DSLR for portraits, or simply curious about how much camera tech has progressed, by the end, you'll understand which model fits your photographic style best.

Let’s unpack the story behind these two: how they perform, where they shine, and what kind of user will find the best value.

First Impressions Matter: Size, Handling, and Build Quality

Before diving into pixels and processors, the first tactile interaction with a camera helps form lasting impressions. A well-built camera can improve confidence and efficiency out in the field. To appreciate how Canon’s designs evolved, take a glance at the physical contrasts.

Canon 40D: Professional Feel, Mid-Size SLR

Canon’s 40D notably positions itself as an "Advanced DSLR.” It sports a solid mid-size body weighing around 822 grams, which is on the heavier side compared to the 700D. Its dimensions of 146x108x74 mm mean it feels substantial and sturdy, a characteristic inherited from the semi-pro 30D it replaced.

One immediately notices the 40D’s robust, environmental-sealed magnesium alloy body. This weather resistance adds peace of mind for landscape shooters, outdoor enthusiasts, and event photographers who might face various shooting conditions. Canon designed the 40D for durability with a pronounced grip that fits hands well, giving a reassuring heft that many professionals appreciate during extensive sessions.

Canon 700D: Compact, Lightweight, and User-Friendly

By comparison, the EOS 700D is Canon's entry-level DSLR, crafted to be compact and approachable, especially for new photographers. It comes in at a modest 580 grams (body only), with smaller dimensions: 133x100x79 mm.

Although it lacks the extensive weather sealing of the 40D, its plastic build with matte finish feels comfortable and easy to carry - ideal for travel or street photography. The grip is shallower but still ergonomically rounded, suiting extended handheld use without fatigue.

For me, the 40D's heft and sturdiness feel more professional but less portable, whereas the 700D invites casual, on-the-go shooting - a pivotal consideration depending on your shooting style.

Design Evolution Through the Lens of Controls and Display

An experienced photographer knows the importance of intuitive controls and screen interfaces. Both models exhibit Canon’s strong design language, but with notable differences reflecting advances over the years.

Control Layout: 40D Prefers Dedicated Buttons; 700D Emphasizes Touchscreen

On the 40D, controls are more traditional - physical buttons and dials dominate the top and rear, giving direct access to ISO, white balance, exposure compensation, and drive modes. The top LCD panel (small but effective) clearly displays key shooting parameters, complementing the optical viewfinder’s 95% coverage and 0.6x magnification for accurate framing.

The 700D, meanwhile, embraces the touchscreen revolution with a fully articulating Clear View II TFT LCD panel, boasting a much higher 1040k-dot resolution. This makes image review and menu navigation smoother and more engaging, especially for users familiar with smartphones. The rear LCD swivels and can flip out to face forward, beneficial for video blogging or tricky angles.

However, the 700D’s pentamirror optical viewfinder is less bright and slightly smaller (0.53x magnification) than the 40D’s pentaprism viewfinder, an expected tradeoff at its price point.

The bottom line? If you prefer tactile feedback and traditional DSLR ergonomics conducive to pro shooting, the 40D’s layout edges ahead. But if you value an interactive touchscreen with flexible positioning, the 700D has significantly modernized the user experience.

Peering into the Sensor: Technology, resolution, and Image Quality

At the heart of any camera lies the sensor, dictating resolution, low-light capability, and dynamic range. Comparing these two Canon models reveals interesting shifts in sensor technology between 2007 and 2013.

Canon 40D: 10 Megapixels with Classic CMOS Sensor

The 40D features a 10.1-megapixel APS-C CMOS sensor (22.2 x 14.8 mm). With a pixel pitch designed for cleaner color depth and reduced noise, it delivers solid image quality with respectable mid-tone gradation and color fidelity.

DxOMark assigns the 40D an overall score of 64, with a color depth of 22.1 bits and dynamic range around 11.3 EV. Its native ISO runs from 100 to 1600, extendable to 3200, an impressive feat for its generation.

Canon 700D: More Megapixels, More Noise Handling

Canon doubled the effective resolution in the 700D to 18 megapixels with a slightly larger sensor area (22.3 x 14.9 mm). This jump facilitates finer detail and larger print sizes, suitable for cropping and landscape work where resolution matters.

The 700D scores slightly lower overall (61), with a 21.7-bit color depth and 11.2 EV dynamic range. Interestingly, its max native ISO reaches 12,800, allowing more flexibility in low-light shooting, although higher ISOs introduce more noise compared to modern cameras.

In real-world use, the 700D’s sensor is a mixed bag - offering sharper output at base ISO but noisier grain at high sensitivities, whereas the 40D’s sensor performs more consistently at moderate ISOs but with less fine detail due to lower resolution.

For landscape photographers and studio portrait shooters prioritizing detail and print size, the 700D’s sensor has an edge. Meanwhile, the 40D appeals to users who want cleaner mid-ISO images and dynamic range - valuable for outdoor and event photographers.

Autofocus Systems: Speed, Accuracy, and Tracking

Fast and reliable autofocus can make or break your shots in action-heavy genres like sports or wildlife photography. Both these Canon DSLRs use phase-detection autofocus with 9 focus points, but the implementation varies.

Canon 40D: Nine-Point AF, No Cross-Type Data

The 40D’s nine-point autofocus system includes only one cross-type sensor (center), which can limit focus precision in challenging scenarios. There’s no face or eye detection, and the camera lacks live view AF assist.

Still, the 40D’s phase-detection AF is very fast and dependable through the optical viewfinder, making it suitable for action photography in good light.

Canon 700D: Nine Cross-Type Focus Points, Touch AF in Live View

The 700D improves on this by equipping all nine focus points as cross-type sensors, boosting precision. It also introduces Canon’s Hybrid CMOS AF system for live view, allowing touch-to-focus and face detection - game-changers for video and stills in live view mode.

Its autofocus speed in live view is slower than dedicated mirrorless systems but remains respectable for entry-level DSLR video work and casual shooting.

For wildlife and sports, the 40D’s faster viewfinder AF tracking under daylight potentially outperforms the 700D despite fewer cross-type points, especially as the 700D capably handles video AF better. Neither camera has advanced AF tracking algorithms seen in modern successors but remain effective in their own eras.

Burst Shooting and Shutter Performance: Catching Fast Action

If you’re photographing moving subjects, sports, or wildlife, frame rate and shutter reliability are critical.

Canon 40D Brings 6.5 FPS

The 40D shines here with a continuous shooting speed up to 6.5 frames per second - a remarkable rate for its time and still respectable today. The shutter speed ranges from 30 seconds up to 1/8000th of a second, accommodating both long exposures and fast action freezing.

Canon 700D Slows to 5 FPS

The 700D offers a somewhat slower 5 fps burst rate and a max shutter speed of 1/4000th second. While ample for general photography, sports shooters might find the shutter speed and burst limits a tad restrictive.

Both cameras allow shutter priority and manual exposure modes, fine for controlling creative exposures.

Video Capabilities: An Unequal Match

Though neither excels as a primary video camera, the 700D pushes Canon’s video features forward significantly.

Canon 40D: Still Photography Focused

There’s no video recording capability on the 40D, a limitation by modern standards but typical for DSLRs of its time.

Canon 700D: Full HD Video with Live View AF and Microphone Input

The 700D steps into full HD recording at 1080p with variable frame rates (24, 25, 30 fps) as well as HD 720p and VGA modes. It supports H.264 compression and offers a built-in stereo microphone plus an external microphone input. The articulating touchscreen also makes framing video shots convenient.

If you intend to shoot video alongside photos, the 700D is a clear winner.
