Better motion-focus for DSLR video with Canon’s EOS 70D



20130702_hiRes_dafTech_frontShooting DSLR video has often had trouble with auto-focusing on moving subjects. But Canon‘s EOS 70D is a game-changing camera with “dual-pixel CMOS AF” for continuous, smooth, auto focus.

With the EOS 70D’s touchscreen LCD screen, you can tap on any visible subject for the lens to maintain focus on the subject, even when the depth changes.

This brings DSLR video production up in line with standard camcorders, which have often been used for better action focusing.

Without “dual-pixel CMOS AF” and Canon’s new Stepping Motor (STM) lenses, a digital SLR would shift focus back and forth on moving subjects (and sometimes even stationary subjects, too). With this new combination from Canon, amateur and professional videographers and podcasters can now get smooth auto focus.

Also don’t forget that the Canon EOS 70D is an amazing DSLR for still photography, too!

The EOS 70D is a cropped-sensor digital SLR that can record up to 30 minutes of 1080p HD video at up to 30 frames per second. The Canon EOS 70D  camera body is priced competitively for professionals at $1,199 ($1,099 on Amazon.com) and is available today.
