Description — Tamron 151B
The Tamron 151B is a 17mm ultra-wide-angle prime lens built on the versatile Adaptall mount system. Covering full-frame sensors and categorized as an ultra-wide-angle type, it offers a fixed focal length ideal for wide, expansive compositions. The Adaptall mount allows the lens to be paired with interchangeable mount adapters across different DSLR camera brands, giving it a level of cross-platform flexibility that fixed-mount lenses cannot match.
Focusing is fully manual, requiring hands-on control with no autofocus capability. The maximum aperture is f/3.5, and the lens accepts 67mm filters — a widely available size that works with most standard filter systems. At just 270g, the 151B is a compact and easy-to-handle wide-angle option.
There is no image stabilization on board. This lens suits photographers looking for a lightweight, adaptable ultra-wide prime with manual-focus character across a range of compatible camera systems.
