Tamron SP 45mm f/1.8 Di VC USD £600/$600
Superb CENTRE SHARPNESS WITH ADDED STABILITY
Some say you don’t need stabilisation in fast lenses, but if you want to take advantage of prime lens image quality at medium aperture settings, stabilisation can be a real help – hence the inclusion of Tamron’s Vibration Compensation (VC) system in this lens.
The modest f/1.8 aperture rating in this ‘standard’ prime helps keep the size down and the weight off, and the lens is nicely engineered, with premium build quality and weather seals. At 45mm, the focal length is a touch shorter than the more standard 50mm. This equates to 67.5mm on a DX-format body, though the lens is also full-frame compatible.
Autofocus isn’t superfast, but it was highly accurate in our tests. The stabiliser gives a benefit of about four f/stops, and manual focusing benefits from greater travel in the focus ring than with the other lenses on test. Sharpness is excellent, even when shooting wide open, while bokeh is impressively smooth, both at f/1.8 and when stopping down.
