one thing to watch out for,when using the zoom button,dont just let it go after you zoom,or it will click and the noise will be recorded. however,if you edit and can dub different audio then it wont matter. that said, we love the camera.ive been thinking about an off board mic for sterio audio,,just for fun. but since this camera is kinda old now,finding extra parts is kinda tough. when we bought it,they were just comming out and then everything was available,but now,several years later,,, well they arent. ebay or maybe canon outlet in the usa.in fact i just bid on a remote for it,we lost the other one. man,they come in handy.id probly also want a clear over lense to protect the main lense from grit and crud. cheaper to get a new cover than new lense.

Here are the rules: 1) Every time a character says or does something that's supposed to be funny but comes off completely lame instead-take a swig. 2) Every time the movie veers off into some completely random direction that has absolutely nothing what-so-ever to do with anything, take a swig. 3) Every time a transformer does a somersault or twist in the air in slow motion before attacking-take a swig. Follow these simple rules and you'll be bombed 15 minutes in. Seriously. While watching this movie I kept thinking how many millions of dollars were spent to provide us with idiotic jokes about red coffee cups in yellow rooms and effeminate assistants with Russian accents. Every time I see one of these movies, it saddens me. Given the insane visuals-tight, more serious stories could have really made this series into something amazing. Unfortunately that's not the case. At least there's no leg humping in this one. That's something I guess...

Written by one of America's hottest contemporary erotica writers the author takes us on a real life tour of her private world of sex slaves, swinging and BDSM. In contrast to most readers pre conceived notions where the `sadism' part of BDSM lifestyle is usually a description of a master beating the living daylights out of his slave, Maria Isabel Pita describes her relationship with her master as a pretty well wholesome practice of living out her fantasies ......Yes there are rules and considerations to a good relationship and the results can only be understated as very very satisfying. Being a master erotica writer the author manages to describe her life in a manner that takes the reader on a delicious and vicarious trip into a world that generally are only deep and hidden fantasies of most women ....This real life exploration of a sex slave/master relationship make these fantasies not only seem more plausible but also delicious .....
