Tamron 18-270 f6.3 PZD - impressions of a daily shooter

After going through two Sigma 18-250 lenses in two years, I decided to give a Tamron 18-270 f6.3 Di II VC PZD a try. Tamron promised improved AF performance with a new ultrasonic AF drive and offered a five year warranty, which was definitely something I could use after spending over $800 on a Sigma 18-250 designed to last only 50K shots. The new lens was also much smaller and lighter, which made it easier to carry it around, given that sometimes I spend hours with a camera in my hand.
