Description — Tamron 45mm f/1.8 AF Di USD
The Tamron 45mm f/1.8 AF Di USD Lens is a full-frame compatible prime lens built for DSLR camera systems. With a 45mm focal length sitting squarely in the standard range, it delivers a natural perspective suited to a broad range of photographic subjects. The f/1.8 maximum aperture provides notable control over background separation and opens up shooting in challenging light.
Focusing is handled via both autofocus and manual focus modes, giving shooters full flexibility on the fly. The lens is offered in Canon EF, Nikon F, and Sony A mounts, making it accessible to a wide range of DSLR users. A 67mm filter thread allows for straightforward use of standard circular filters.
At 540g, the lens has a substantial build quality consistent with a fast prime designed for full-frame coverage. Note that this lens has no image stabilization, so handheld shooting in lower light will depend on shutter speed and, where available, in-body stabilization from the camera body.
