I'm just about to plunk down my money for a 450. I currently have a DSR-390, which I happen to love, but I like the extra features of the 450. The one difference from what Peter did is I'd like to go for the wide angle (still "pro" level, though) YJ12x6.5KRS lens. I currently have the 1/2" version on my 390, and I absolutely love it. Once you go wide, you can't go back! I really would like to test the 450 vs. my 390, which is probably the king of low light sensitivity. I KNOW the 450 can't be as good, since it's an F11 camera vs. F13, and the f-stop of my current lens is 1.5 vs. f2 on the 2/3" YJ12x6.5. But Sony tells me I can gain up the 450 to a very high level and still get a decent picture. (Sorry that I'm bringing up more questions than I'm answering!) The other thing nobody has been able to answer (including Sony at the DV Expo East last month) is the slow shutter. The brochure says it will do all the way down to 1/4 second (similar to a DSR-150 or 170) but NO ONE has been able to verify this. I've emailed a guy here on the east coast who owns one, but he hasn't had the time to check out the slow shutter. And last but not least - the price. Do I shell out major bucks now (and I need to sell the 390 to pay for it) or do I wait for the next generation HDV? I'm not happy either with any of the products that are out (but the JVC looks like the most promising).
Oh, yeah - and this is my first post!
