The Powershot A490 features a 3.3x optical zoom lens with a 35mm equivalent of 37-122mm and a maximum aperture of f/3.0 (W) - f/5.8 (T). When powered down, the lens will retract inside the camera for protection.

An advanced TTL AiAF 9-point autofocus system permits the camera to automatically select the primary subject even when off-center. The focusing range is:

  • Normal AF: 2-inches/5cm - infinity (W), 9.8-inches/25cm - infinity (T)
  • Macro: 0.4-inches - 1.6 ft./1-50cm (W), 9.8 in. - 1.6 ft./25-50cm (T)
In low light conditions the focus-assist lamp helps to illuminate the subject for accurate focusing.






canon_a490_flash.jpgHere you can see the A490's flash unit and AF Assist lamp (mentioned above). The flash shoots in a variety of modes: Auto, Slow Synchro, Red-eye Reduction, Auto Red-eye Correction, Shutter Sync: 1st curtain, Flash On, Flash Off; FE lock, Smart Flash Exposure. Since the camera runs on AA batteries, the flash is slow to recharge, taking around 10 seconds.

The flash range at ISO Auto is:

  • Wide: 1-9.8 ft./30cm-3.0m
  • Tele: 1-6.6 ft./30cm-2.0m
