"Real chip"? The HV20 has a 1920x1080 1/2.7" CMOS sensor. And for Titan\'s needs I doubt the EX1 is ten times better.
It\'s got 1 chip..
It\'s a very small chip...
It\'s HDV..
That is not true HD. That is a joke. They print 1 or 2 frames a second or something ridiculous like that at about 19 MBits/sec. That is extremely low. That\'s how they are able to shoot an "HD" image on mini dv tapestock.
It\'s a horrible compression that you can\'t shoot anything with any type of somewhat fast motion without it totally looking like crap.
BUT, for a cheap camera I\'m sure it\'s fine. As long as you aren\'t expecting anything to look very good.
The EX1 is more like 20Xs better.
