hello all i have a pentax zx-7 with a promaster 28-200 lens that i've been using for the last six years and i love it. i need to break down and find a digital camera to replace it. i am not a professional (mostly family and sporting events), but i need a comparible camera but in digital. what would be a good suggestion for a camera to replace my pentax of equal quality? important features: wide angle zoom, little to no lag time after snapping shutter also, i know the new digital will not come with a zoom lens, would i be able to use my old lens with the new digital? would i be happy with a digital rebel? thanks for any input!
