The Sony DSC-F717 is a bridge digital camera announced by Sony in 2002. It features a 5.0 megapixel CCD sensor (8.80 × 6.60 mm). It has a 38–190 mm equiv. Carl Zeiss Vario-Sonnar lens with an aperture of f/2.0-f/2.4, which is considered as a very fast lens in its class.

Photos taken can be saved as JPEG or TIFF. Recording movie clips in MPEG EX/HQX is also possible.

Special features[edit]

  • The camera uses a swivel body, good for complicated situations. It can be rotated in 36 degrees angled down (for overhead shooting) or 77 degrees angled upwards.
  • The DSC-F717 uses the relatively rare "Hologram AF Assist" which helps the contrast detect AF system to lock AF in low light.
  • It also features NightShot and NightFraming which removes the infrared cut-off filter from the CCD thus making the camera "able to see in the dark" and enabling two infrared LEDs illuminating the scene at short range. Aperture and similar settings are forced to auto and are limited (this might be due to the fact, that it was possible to photograph through thin clothing with an additional IR passing filter). Because of the limitations it's giving the opportunity to be used in IR photography only partly.

Defective batches[edit]

Some early production units (most units produced in September/October 2002) may experience inaccurate focus with Laser Hologram Focus enabled. Sony admitted the problem as a minor design flaw and offered free examination and repair service. Serial numbers of potentially affected units were also announced. Detail of this particular design flaw was never announced. [1]

Around 2004-05, many F717 users reported CCD-related defects. It was later confirmed that many Sony CCDs made from 2002 to early 2004 suffer from a large-scale manufacturing defect. [2] As a remedy, Sony offered free CCD replacements for affected units till 2007, and in some countries, till 2010. This recall would cover units with expired warranty.
