Part 3. Exercise
Review: Things I like...- price- sizeThing I didn't like and made me return- performance under regular indoor house lighting very grainy and considerably worse than my 8mm analog. Doing further research it appears this is likely not unique to Canon but common to DV camcorders. I am going to stick with my 8mm for a couple of years until DV tech improves since much of my use is indoors filming kids, etc. 
 Polarity: Positive

False
