In theory, the Tamron 18-400mm f3.5-6.3 Di II VC HLD could be pretty difficult to wrap your head around, but rest assured–it exists. Tamron just announced the new lens and it is quite the option for APS-C sensor DSLR owners. Even crazier: it’s pretty small and light weight. It comes in at 4.8 in. and 24.9oz. Now even crazier, it’s only going to cost $649 when it hits the streets next month.
Now, besides the 22.2 zoom ratio, the Tamron 18-400mm f3.5-6.3 Di II VC HLD has 16 elements in 11 groups. All of that glass is protected by the Moisture resistant construction that Tamron is saying the lens has. To keep it as compact as possible, it has a zoom lock to ensure that it doesn’t accidentally extend out.
The press release is after the jump.
