The Digital8 line was conceived as a path to digital for current owners of 8mm or Hi8 camcorders. The DCR-TRV840 succeeds in that regard, playing back both 8mm and Hi8 tapes. The TRV840 can also be used as a digital still camera, recording megapixel stills onto the included 8 MB Memory Stick, or it can record MPEG movies. MPEG movies usually are much smaller than DV footage, and can more readily be e-mailed, or posted on the Web. Unlike most MPEG modes, however, the TRV840 lets you record for as long as you want, your only limit is the size of the Memory Stick.
Sony put in a 15x optical zoom and paired it with Super SteadyShot image stabilization. Image stabilization is a handy technology that helps to eliminate the shakiness associated with high zoom levels. The only way to avoid shakiness completely is to utilize a tripod, table, or other stable surface. The 3.5-inch LCD is the best way to frame your shots, although you can use the black-and-white EVF to preserve battery life.
In addition to the normal slew of ports (IEEE 1394, S-Video, Mini AV) that have made their way onto TRV840, there's also a USB port, which, with some included software, offers some interesting functions. There is also one very important port on the TRV840: a mic input. Not only do most camcorders have poor built-in microphones, but also they are often situated too near the tape mechanism, meaning you get the annoying throbbing sound of the tape pulled through the heads.
The DCR-TRV840 comes with a power adapter, InfoLithium battery, 8 MB Memory Stick, remote control, two AA batteries, AV cable, lens cap, shoulder strap, USB cable, and software CD-ROM.
