Panasonic SDR-SW21 review


Waterproof, shockproof and dustproof, is there nothing this compact SD-card, MPEG2 camcorder can't handle?

Waterproof and shockproof powers mean this camcorder can roll with the punches – but its movie performance is far from knockout

Panasonic SDR-SW21EF


Not only is Panasonic's SW21 waterproof to a depth of 2m but it's also shockproof (up to 1.2m) and dustproof too. It's a standard definition camcorder, recording movies and stills to SD/SDHC cards. These files can be uploaded quickly and easily to...

The practicality of having a camcorder that’s this durable is a big plus point. However, with a price tag of over £300 the video quality just doesn’t pass muster. Upgrade it to HD and take a look at the pricing of other pocket-sized high-def shooters...

The underwater picture quality is excellent, just what I wanted. 2 x Record buttons very useful too, Esp for videoing children. You can operate the camera at waist hight instead of having to get down on the floor with the children. However I find I...

Product Specifications

The SDR-SW21 camcorder combines a rugged, compact body with waterproofing that allows use in seawater to a depth of 2 meters, shock proofing that protects against falls from up to 1.2 meters, and dust proofing. This camcorder, offering its small size, light weight and superb mobility made possible by SD/SDHC memory cards, let users shoot video with the same casual ease and carry-about convenience they enjoy with small digital still camcorders. A waterproof design, taking advantage of the water resistance of an SD/SDHC memory card, lets you use the SDR-SW21 camcorder underwater to a depth of 2 meters. The SDR-SW21 camcorder can even be used in seawater, so users can take moving images of friend's snorkeling or tropical fish darting in and out of coral reefs. You can use the SDR-SW21 camcorder at the beach, a ski resort, or a host of other active, outdoor situations where you wouldn't dare use a conventional camcorder. Unlike recording media such as hard disk drives or DVD discs, SD/SDHC memory cards require no drive mechanism. This gives the SDR-SW21 camcorder sufficient impact resistance to prevent malfunction when dropped from up to 1.2 meters. Combined with its dustproof and waterproof features, this makes it the ideal camcorder for anytime use outdoors, in active situations, and for casual everyday video shooting. The SDR-SW21 camcorder features the YouTube Uploader function that makes video uploading super easy! Simply set the camcorder to "Web Mode" and it will record the movie in a YouTube compatible format. After shooting connect the camcorder via USB to a PC and the YouTube Uploader automatically starts. Simply follow the procedure to upload your video clips to the YouTube video-sharing site. The SDR-SW21 camcorder offers a function that simplifies the process of copying recordings from the memory card or hard disk drive to a DVD. No PC is required. A DVD disc created this way can be easily played directly from a DVD player.
