I can't get the 18-200VR off of my wife's camera these days, and she does get some wonderful shots with it. Thus I am left with my newest acquisitions: 12-24/4 and 70-300VR. That leaves a big hole in the middle. My principal photo interests are landscapes and flowers, so I'm about 90% convinced that my next purchase should be the 17-55/2.8. Does anyone think I'd be better served with the legendary 28-70? It does cover the "hole" better :wink: . p.s. whichever one I decide on, it will probably stay on my camera 80-90% of the time.
