SUMMARY
Adrian Alford evaluated the Tamron 12-20mm f/2.8 zoom lens for astrophotography, specifically testing its performance on Milky Way shots. He found that the lens delivered sharp stars in the corners at f/2.8, a quality often associated with prime lenses. Alford's process involved meticulous planning, including scouting locations in daylight and using apps like PhotoPills to predict the Milky Way's position. He also emphasized the importance of focus locking and foreground lighting. The test suggests that a fast, wide-angle zoom can be a viable alternative to primes for capturing the night sky.
