First Impressions: Tamron 100-400mm f4.5-6.3 Di VC USD

When I first got to see and hold the Tamron 100-400mm f4.5-6.3 Di VC USD lens, I didn't think that it would be anywhere as lightweight as it is. To be very honest, I've seen and held 70-200mm f2.8 lenses that are heavier and in some ways bigger at least when collapsed. Granted, this lens has external zooming.
