Sony HDR-CX7 AVCHD Camcorder
Audio
The CX7 comes equipped with a built-in 5.1-channel onboard microphone. We tested the CX7’s onboard microphone in a variety of sound scenarios, from a quiet golf course to a crowded baby shower party. We were pleased with the overall perfor- mance of this camcorder’s built-in mic. Even at very close range, semi-loud voices were not very muffled or distorted. When we tested the microphone outdoors, again we were pleased with the microphone's performance in picking up both ambient noise and the sounds created by the golfer's swing and golf shot. We were not able to hear the camcorder motor while recording in a quiet setting. For picking up good-quality voice, the best results were from in front of the camcorder and about 4 to 6 feet away.
Format
The AVCHD format's problems with motion artifacts seems to be a thing of the past, and the HDR-CX7 is evidence of this new direction for Sony camcorders. Testing the CX7’s motion com- pensation turned out great results with very few compression artifacts and little ghosting. Under daylight conditions, the CX7 showed very sharp and smooth images. We were very pleased with color reproduction. Under indoor lighting conditions, the

CX7 still performed fairly well, with a slightly slower auto focus and increased digital noise. Low-light conditions will definitely be your biggest enemy in maintaining pristine images. Over- all, we were pleased with the smooth motion of our recorded images under indoor conditions. We tested the CX7’s image ca- pabilities in a more difficult task with an ocean sunset, moving along a freeway, and found the motion to be very smooth with no visible artifacts, the auto focus quick and sharp and the color vivid and accurate.
