Featured on the PowerShot 310HS is an 8x wide optical zoom lens with a 35mm equivalent of 28-224mm. With a maximum aperture of f/3.0, it handles low-light situations very well on the wide end of the zoom. Also assisting with low-light shooting is Canon's Optical Image Stabilization with their new Intelligent Stabilization system. This system detects the camera's movements and selects the appropriate IS mode for the situation. When the camera is powered off, the lens retracts into the body where a lens cover closes for protection.
- Auto: 0.4 in (1 cm) - infinity (W), 3.3 ft. (1 m) - infinity (T)
- Normal: 2.0 in. (5 cm) - infinity (W), 3.3 ft. (1m) - infinity (T)
- Macro: 0.4 in. - 1.6 ft. (1-50 cm) (W)
The small built-in flash has a range of up to 13ft. at the wide end. Working with the camera's face detection to detect brightness, the flash is great at producing correctly lit faces that show natural color and tones. It operates Auto, Flash On, Slow Synchro, Flash Off.
Canon has kept the top of the 310HS very simple with just the power button shutter release and zoom control.
Featuring a high quality 3.0-inch, 461,000 dot LCD screen, it is a pleasure to both frame and view your images in any lighting situations.
Starting from the top: the red record button will start and stop video capture, no matter what the camera's shooting mode is. The 4-way controller allows you make selections in the menus and search your captured images while also offering several setting shortcuts to frequently used options; up will access the exposure compensation, right is the flash mode, left is the macro key, and down will change the display options in record or playback modes. At the bottom is the playback button. Canon has moved the shooting mode switch and Menu button off of the back of the camera and placed it on the right side of the camera.
Here on the right side of the camera you can see the switch and menu button described above. You can also see the Input/Output ports. On top is the HDMI output for viewing your HD videos on a HDTV. On the bottom is the combo USB 2.0, A/V cable.
The PowerShot 310HS is capable of using SD/SDHC/SDXC and Eye-Fi memory cards. The camera is shown here with a PNY Pro 8GB class 10 SDHC card. With the camera's burst and HD video capabilities, we recommend a larger capacity card with a speed of at least class 4.
Powering the 310HS is a small 3.7V, 760mAh Li-Ion rechargeable battery. This battery allows for the capture of up to 210 images on a single charge. This is not a great battery life so the included quick charger will get plenty of use.
