Quick Tamron 18-200 and Sony 55-210 Comparison

Honestly I think that for me those 18-200s defeat part of the purpose of having a NEX which is a compact size. If its going to be that bulky i'd consider taking my SLR instead. With the 18-55 there is still enough of a size advantage for me to want to take the NEX. That is only my personal opinion and I know that others have different needs and different preferences.
