The a6400 is one of the most popular APS-C cameras in South Africa: fast autofocus, a flip screen and a small body. It has no in-body stabilisation, so lenses with Tamron's VC stabilisation make a real difference in low light and for handheld video.
On the Sony a6400, every lens gives a field of view about 1.5x narrower than its focal length suggests. Below, each lens shows its full-frame equivalent on this camera. Tamron's APS-C lenses (Di III-A and the 16-50mm) are designed for this sensor size; its full-frame lenses fit too and become longer, which helps for portraits and wildlife.
The camera has no in-body stabilisation, so lenses marked VC (Tamron's Vibration Compensation) give steadier handheld photos and video.
Where to start
For most Sony a6400 owners the best first Tamron lens is the Tamron 17-70mm F2.8 Di III-A VC RXD (B070): it gives an F2.8 everyday range of 26-105mm equivalent and adds the stabilisation the body lacks.
