test of SONY camcorders
I did some tests with 3 SONY camcorders D8, Hi8 and Video8. Unfortunately, it was in the evening, so I had to use 25W compact fluorescent bulb. It caused a red tone of test image, although auto white balance should handle this. All camcorders were tested with autofocus.
As resolution test pattern I used EIA1956 test chart printed on A4 paper (click the image to see full size). The image was sized (zoomed) to fit to screen of TV set.
I tested resolution of camera part (video out, without
recording to tape) and also the whole camera including
tape recording. The measurement was made only
approximately, without special equipment. For precise
measurement the white parts of the test image should be
set to white level by adjusting manual exposure. But
anyway, also my measurements provide a view of
differences between D8, Hi8 and Video8 standards and show
what can be expected from this camcorders.
The next table compares real results with official specifications of the video standards:
SONY DCR-TRV900 (3 chip miniDV) and SONY TR7000 (1 chip Digital8) tests
The next pictures were taken by John Beale,
who has fantastic website about TRV900 (it is also
perfect source of information about camcorders): TRV900 page.
None of tested cameras achieves the resolution stated in specification. It is interesting, that Video8 camera part provides better resolution than Hi8 camera part. As concerning recorded picture to tape, the best image is provided by Digital8, then by Hi8 and the lowest resolution has Video8.
It is interesting that real achieved results show, that Digital8 has lower resolution than it is claimed by Hi8 standard. Likewise Hi8 achieves in real life worse resolution than it is claimed by Video8 standard.
Also it is necessary to mention, that daylight tests result better than tests with fluorescent or incadescent light.
