Canon 70D Camera Review

The Canon 70D has a good range of features for playing, reviewing and managing your images. These include a choice of Picture Styles and User Defined styles.

It also has an extremely low shutter lag time spec, allowing shots to be perfectly timed. This is especially useful for moving subjects.

Dual Pixel CMOS AF

Canon’s Dual Pixel CMOS AF technology lets 80% of sensor pixels pull double-duty for image capture and phase detection autofocus. This makes Live View and movie recording more responsive by eliminating the need for contrast-detection AF, which is slower than phase detection.

Prior to this, mirrorless cameras used only contrast detection for video recording, DSLRs used a mix of traditional phase detection and contrast detection, and camcorders relied on contrast detection. This’searching’ method slows the AF system, making it difficult to focus on fast-moving subjects and especially in low light conditions.

With DPAF, the camera can seamlessly switch between phase detection and imaging with no loss of performance or deterioration in image quality. This allows wide AF coverage, smooth focusing, and faster, more reliable tracking during both still and video shooting.

Face Detection

If you want to use the 70D for portraits this is a really useful feature. The camera can recognize a face in a scene and then create an AF box around it. It can also track a face as it moves around the frame.

The sensor on the photography canon 70d has two photodiodes underneath each pixel. These can be read separately to provide phase detection AF or together as conventional imaging pixels. The camera can therefore devote a huge proportion of its pixels to autofocus, but still deliver sharp images when shooting live view.

The Canon 70D is also capable of high dynamic range (HDR) photography. It can record up to seven frames of bracketed exposures which are then automatically combined in-camera using a special HDR mode.

Face Tracking

The 70D offers a number of useful features for portrait photographers. Its ergonomic design makes it easy to use and its built-in 3.5mm jack allows users to record and monitor audio during shooting. It also offers a variety of lenses with image stabilization, ensuring sharp images even when the camera is hand-held.

The Canon EOS 70D’s unique Dual Pixel CMOS AF sensor splits each pixel into two light-gathering photodiodes that can either be read individually for phase detection autofocus or together for still imaging. This results in the 70D achieving faster focus with Live View than most other Canon DSLRs, especially when using a wide-angle lens.

Another key feature is its ability to upload images directly to social media platforms via the Canon Image Gateway. This feature is not available on other DSLRs, and it’s a welcome addition for those who need to quickly share content with their audience.

ISO sensitivity

The camera offers a full range of manual and semi-automatic exposure modes. You can also control the camera using the LCD screen to change settings. The camera also features Automatic Lighting Optimizer. This feature shifts shadows and mid-tones in the histogram to the right, brightening them up.

In low light conditions, the Canon 70D is able to produce sharp and well-defined images with little noise. This is due to its large sensor and APS-C format. However, it may struggle to stop fast-moving subjects such as a hummingbird or racehorse.

The Canon 70D performs well at high ISO settings, retaining good image quality up to ISO 1,600. There is some chroma noise visible at higher ISOs, though, and fine detail can become blurred. It is important to avoid using the highest ISO setting possible, as this can increase image noise and degrade the overall quality of the image.

Evaluative metering

Evaluative metering takes readings from the whole sensor and creates an average for the exposure. This mode tends to underexpose bright areas and highlights, but it can be useful for landscape photography. It also works well for portraits and indoor shots.

There are other metering modes available for more specific situations. For example, partial metering is a Canon-specific mode that measures only a small circular area around the focus point. It’s good for situations where you want to prioritize the exposure of a subject against a bright background, such as a bird against a sky. This method can also help you avoid overexposure in highlight areas. You can also find these modes on your camera’s LCD screen. The camera is able to recognize different scenes and apply the appropriate settings automatically.
