Had this camera a number of years and been very pleased with it and looking to find replacement but wonder what to look at next? I looked on DP Review but wonder if anyone has any tips based on my actual needs. Looking for: more than 4 times optical zoom, anti shake, not SLR & must have 28 mm lens - definitely no wider (don't want have to use wide angle converters). I use the camera almost exclusively for interior room shots, buildings & landscapes in my work closely related to Estate Agency/Real Estate. Help would be useful. Ken
