Nikon's 2002 swivel-lens entry compact — 2MP CCD, 37-111mm inner-twist 3x zoom, CompactFlash
The Nikon Coolpix 2500 was announced on 21 February 2002 at PMA as an entry-level compact with a twist — literally. It brought the swivelling lens of Nikon's higher-end 900/950 series to the consumer end of the range in a smaller, cheaper 'inner-twist' form where the lens unit rotates inside the body shell.
It has a 2-megapixel 1/2.7-inch CCD delivering 1600x1200 images and a 3x Zoom-Nikkor of 5.6-16.8mm, equivalent to 37-111mm. The lens-and-flash unit swivels 90 degrees rearward for self-portraits and 135 degrees forward, and is protected when rotated shut. Twelve scene modes cover common subjects. Power comes from the EN-EL2 lithium-ion battery and images are stored on Type I CompactFlash cards; the body weighs about 165g.
The swivel design makes it a fun, distinctive early-2000s digicam for waist-level and self-portrait angles, and the rotating lens doubles as a lens cover. Output is modest at 2 megapixels, so it appeals to collectors of oddball Coolpix designs and CCD-nostalgia shooters more than practical users.
Check the swivel mechanism first on a used example — it should rotate smoothly with positive stops and the ribbon cable through the hinge is the known weak point, so confirm the camera still powers on and shoots at various rotation angles. Verify the EN-EL2 battery holds charge with charger included, and remember it needs CompactFlash cards, ideally smaller older capacities.
