Panasonic Lumix DMC-FZ15By: Dave EtchellsPanasonic introduces a four-megapixel digicam with the high quality optics of a 12x Leica lens. <<Camera Modes & Menus :(Previous) | (Next): Video, Power, Software>> Page 10:Image Storage & InterfaceReview First Posted: 10/30/2004 |
Image Storage and Interface
The DMC-FZ15 uses SD/MMC memory cards for image storage. An 8MB SD memory card is supplied with the camera (a total joke, the smallest I've seen shipped with a digicam in the last 3-4 years), so you'll want to immediately purchase a larger capacity card to accommodate the large four-megapixel maximum resolution. Entire SD/MMC cards cannot be write-protected, however, the DMC-FZ15's Play menu allows you to write-protect individual image files, protecting them from accidental erasure, unless the card is formatted.
Still images can be saved at one of five resolutions (2,304 x 1,728; 1,600 x 1,200; 1,280 x 960; 640 x 480 pixels or "HDTV," 1,920 x 1,080 pixels), while movie images are recorded at 320 x 240 pixels. Still images also have two JPEG compression levels available: Fine and Normal, plus an uncompressed TIFF setting that records the RGB image with no compression at all.
A full complement of interface software comes with the DMC-FZ15, as does a USB cable for speedy connection to a PC or Macintosh computer.
Following are the approximate resolution / quality and compression ratios for
the furnished 8 MB card. (Compression numbers are based on my own computations.
- You can see how pointless the 8 MB card is, able to hold only four images
at the camera's best JPEG size and quality setting.):
