The Q3 is a compact camera meant for everyday shooting and its design remains similar to previous generations, but with some notable updates for improved usability:
- New higher capacity BP-SCL6 lithium-ion battery is rated to provide 350 shots per charge and uses the same physical design as its predecessor, the BP-SCL4, which can also be used with this camera.
- Magnesium alloy body is sealed to protect against dust and moisture (IP52-rated) for use in harsh environmental conditions.
- New USB-C 3.1 Gen 2 port can be used for transferring, tethering, power delivery, and in-camera battery charging. The Q3 is also Made for iPhone certified to enable a direct, wired connection to an iPhone.
- Micro-HDMI port facilitates working with an external monitor and recorder as well as previewing footage from the camera directly on a TV.
- Accepts one SD-type memory card and supports the UHS II protocol.
