You are absolutelyright of course.Unfortunately I have reached an age where I dont want to have to carry a lot of lenses hence my 18-200vr venture into digital.
When I had film SLRs in the past I needed a donkey to help me.
I realise an all purpose lens is a compromise but so is not carrying a bag of lenses.
It is a much better lens than I anticipated, so I was concerned at the earlier post stating that a similar lens did not like the extra pixels, hence my post.
I recently went to the Hermitage Museum in St Petersburg and took lots of pics of paintings by artists like Monet Picasso Micheal Angelo etc, and inside various Cathedrals, all low light conditions.I was very pleased with the results.Some of these places are almost dark.
