We have the Panasonic 45-200 zoom. It's perfectly nice as a consumer level zoom lens, and my wife uses it all the time for close up shots in the garden. I'm looking at the 100-300 zoom and wondering if anyone who has both would care to comment on the differences.
It looks like the minimum focusing distances are such that they have approximately the same magnification at closest focus (.19x vs .21x.) So I don't think she'll see a huge difference in her images that are shot at or close to the minimum distance. (Of course at anything beyond that there are differences.)
Are there other reasons to purchase the 100-300? Build quality? Image quality at longer focal lengths?
