The Canon EOS 40D, a DSLR camera, has a score of 42/100. Announced on August 20, 2007, and released the same year, it was initially priced at $899. The camera’s dimensions are 146 x 108 x 74mm, and it weighs 822g (1.81lbs).

Looking at these specifications, the EOS 40D is not the most competitive model in today’s market. Its score and launch date reflect its age and limitations compared to more modern cameras. Despite this, the EOS 40D still has its merits, and users may find its features suitable for their needs.

Canon EOS 40D Overview and Optics

The Canon EOS 40D receives an optics score of 45/100. It features 10.1 megapixels, a shooting speed of 6.5 frames per second, and a CMOS sensor with a DXOMARK score of 64. The camera has a Digic III processor, an APS-C sensor size, and a Canon EF-S lens mount. However, it lacks image stabilization and has an aspect ratio of 3:2.

Comparing these specifications to current market standards, the 40D falls behind in terms of megapixels and sensor performance. Modern cameras typically offer higher megapixel counts and better sensor scores, resulting in improved image quality. Additionally, the absence of image stabilization in the 40D may lead to compromised image sharpness, especially in low-light conditions or during handheld shooting.

Despite its dated specifications, the Canon EOS 40D still provides decent image quality for casual photography. However, for those seeking top-notch performance and features, newer models in the market are more suitable.

The higher the number of megapixels, the more detail the cameras sensor can capture.
10.1 MP
Image Resolution
Image resolution is measured in pixels and megapixels, width by height. The higher the number, the higher its resolution.
3888 x 2592 px
Sensor Type
The camera sensor captures light and records the image. Sensors vary in physical size, the number of pixels, and quality.
Sensor Size
The sensor size contributes to the overall quality as well as the dynamic and tonal range a camera can capture. As a rule of thumb, the more surface there is to read the light, the more information it will capture.
15 x 22 mm
Sensor Format
Refers to the most commonly used sensor sizes.
Frame Rate
The number of sequential frames per second the camera can write to the memory card when shooting in burst or continuous mode.
6.5 fps
Lens Mount
The lens mount will tell you what type of lens range you can fit onto the camera body. Often the same camera company will have different lens ranges for different cameras.
Canon EF-S
Image Processor
The image processor in the camera converts the information collected on the sensor for digital storage on the memory card.
Digic III
Aspect Ratio
The aspect ratio refers to the proportional difference between width and height. The most popular aspect ratios are 3:2 and 4:3.
Minimum ISO (Native)
Refers to the lowest native (or 'base') ISO setting. Lower ISO are less sensitive to light but make a cleaner image.
Maximum ISO (Native)
Refers to the highest native (or 'base') ISO setting. Higher ISO is necessary for low-light situations or night photography, but higher ISOs often introduce grain or noise.
Minimum ISO (Expanded)
Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary.
Maximum ISO (Expanded)
Expanded (or extended) ISO is a digitally enhanced feature available on some cameras. It allows you to push beyond the native ISO range if necessary.
Minimum Shutter Speed
The minimum shutter speed will tell you the longest exposure your camera can take without using an external accessory.
30 s
Maximum Shutter Speed
The maximum shutter speed tells you the length inside 1 second the camera will capture. These can sometimes be extended with accessories such as extra external batteries.
1/ 8000 s
Autofocus Points
Autofocus points show where the camera is focusing graphically as squares or brackets in Live View or on an electronic viewfinder. These points are also used for light meter readings.
In-body Stabilization
In-body Stabilization means the camera has a certain technology embedded that counteracts camera shake.
Viewfinder Type
The viewfinder type is either electronic or optical. Electronic viewfinders will have a small screen in the viewfinder. Optical viewfinders will use prisms and mirrors to look through the lens.
Optical (pentaprism)

Canon EOS 40D Video Performance

While discussing the Canon EOS 40D’s features, it is important to note that this camera lacks video capabilities. Unlike many modern cameras, the EOS 40D cannot record video, focusing solely on photography.

Time-Lapse Built In
A built in time-lapse mode will allow continuous shooting throughout a prolonged period of time to be compressed into a sped up video.

Canon EOS 40D Features and Benefits

The Canon EOS 40D’s features score stands at 36/100. The camera has a 3-inch screen with a resolution of 230,000 dots, which is significantly lower compared to modern cameras. The lack of touchscreen functionality and a flip screen limits the user’s flexibility and ease of use. Additionally, the camera does not offer GPS, Wi-Fi, or Bluetooth connectivity options, which have become standard features in today’s market.

When compared to current camera models, the Canon EOS 40D’s specifications fall short in terms of technology and user experience. Despite its solid performance in other areas, the camera’s outdated features make it less competitive in the modern market. Those seeking a camera with advanced features and connectivity options should consider newer models in the Canon line or explore other brands.

External Flash
External flashes are often connected through a hot shoe at the top of a camera, or a cable at the side of the camera.
GPS features in a camera will include location metadata to each of your photographs.
Weather Sealing
Weather sealing capabilities will give you more confidence when shooting in unfavourable conditions.
Screen Type
Touch Screen
Touchscreen allows you to change camera settings and access menus with a swipe of your finger, instead of using buttons.
Screen Size
Screen Resolution
Screen dots indicate the resolution of the LCD screen by including each sub pixel.
230,000 dots
Flip Screen
A flip screen (or articulating screen) is a second screen which can flip out from the side or top of the camera. This rotating screen allows you more freedom to take photos at different angles.
Live View
Live View feature allows you to see a continuous live video of what is being seen through your lens.

Canon EOS 40D Storage and Battery

The storage and battery score for the Canon EOS 40D is 35 out of 100. This camera has one memory card slot, accepting only Compact Flash (Type I or II) cards. Compared to modern cameras, which often support multiple memory card formats and have multiple slots, the EOS 40D lags behind in terms of storage options.

The battery life of the EOS 40D is 800 shots per charge, using a BP-511 battery type. This amount is respectable, but not outstanding when compared to newer models. Additionally, the camera lacks USB charging, which is now a common feature in today’s market.

The Canon EOS 40D’s storage and battery specifications show its age, as it falls short in comparison to current camera options. While it may still be useful for some users, its limitations should be considered when assessing its overall performance.
