Canon 70D: A Review of a Professional and Versatile Camera

Canon 70D Camera Review

The Canon 70D was a hit with professional reviewers and buyers alike. Its focusing in live view mode earned it especially high marks.

Image quality is excellent, delivering prints at sizes comparable to the competition at all sensitivities. The new sensor delivers noticeably better dynamic range and less noise at higher ISOs than the 60D’s.

Dual Pixel CMOS AF

The Canon 70D is a great camera for filmmaking. Its touch-screen interface makes it easy to control the camera while a subject is moving. It also offers a fast, precise AF system that can track subjects in real time.

The CMOS sensor has dual photodiodes in each pixel, which can act independently to perform phase-detection autofocus and imaging simultaneously. In this way, the system can use information from all pixels for focusing purposes without sacrificing the image quality of conventional phase-detection AF.

Unlike competing systems that limit the number of pixels for focus detection, every pixel on the CMOS sensor can contribute to determining sharpness during Live View and movie recording. This results in a dramatically improved autofocus experience.

It’s a remarkable feat of engineering that’s already found its way into many smartphones. DPAF is also compatible with the full range of existing Canon EF and EF-S lenses, making it a truly universal autofocus technology.

Creative Filters

The 70D has a wide range of Creative Filters to unlock mood and emotion. You can select these in Playback mode on either the largest Raw or JPEG file size and apply them without the need for any other software.

You can also apply the same effects to photos that you shoot by putting the camera into a special Creative Filter mode and using the Q button during shooting. The same six Creative Filter effects as are available in the special mode can be used in this way during capture (as well as HDR Art).

This mode uses a feature of the camera’s CMOS sensor that splits each pixel into two photodiodes, one for phase-detection AF and the other for imaging. This allows it to use all of the pixels for AF and only switch them into image recording when it needs to do so. As a result, the CMOS sensor has no blackout during autofocus and the system is able to lock on to moving subjects more quickly.

Live View Mode

With Live View shooting, you can shoot by viewing a real-time image on the camera’s LCD monitor. This allows you to check focus and exposure with greater ease than with the optical viewfinder.

The display on the screen can be magnified by up to 5x, which is especially helpful when manual focusing. The screen also displays a white box that can be moved around the image frame (except to the extreme edges) to aid in precise autofocus or manual focusing.

More advanced cameras even allow you to place a grid or histogram on the display while in Live View mode. This can help you make more informed decisions about your composition and exposure settings in the field, speeding up your creation flow.

In certain conditions, such as under bright sunlight, the brightness of the image displayed on the LCD monitor may not match that of the actual captured image. Similarly, with a very bright light source in the picture, the subject might be blackened on the LCD monitor but correctly displayed in the captured image.


The 70D’s built-in Wi-Fi feature makes it easy to share photos and videos with compatible devices. It can connect to a smartphone, tablet, computer, Canon iMage Gateway Web service (free registration required) and DNLA-compatible devices. However, it takes a little effort to set up.

Overall, the Canon 70D is a solid choice for photographers. The camera’s superior Dual Pixel AF system provides consistent focusing for photos and videos. It also has a high ISO range and impressive image quality.

The camera also includes a number of fun and creative filters. These include Grainy Black and White, Soft Focus, Toy Camera Effect, Art Bold Effect and Miniature Effect. The camera also features a handheld night scene mode that combines several images to reduce camera shake and HDR backlight mode. The camera does not have 4K recording or a headphone jack, but these features are not necessarily deal breakers for most people.
