I am using the 14-45mm & the 40-150mm and they are amazing. Virtually no shutter lag, 15 shooting modes, great set-up/control features, and a practical battery life. I am stunned. All for less than $850 bucks! Of course, i have yet to pick up an external flash and the ginormous memory card - but hey, first things first, right?
Just thought you'd all like to know!
