Re: Tamron 18-270mm better than Sigma 18-200mm?

I have the Sigma 18-200 non HSM lens and it did take great images. I found that f8 was the sweet spot for sharper image. The other reason I got the Tamron was that it had more 'reach'. I was at San Diego Zoo and the Sigma failed at it's max zoom, it wasn't close enough for me.
