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. . thephoblographer.com
