Tamron 10-24mm lens test

Santa Fe Depot, Brownwood, TX

Been testing a new (for me) Tamron 10 to 24 mm wide angle lens adapted to the Sony a6000 camera.
The above shot of the restored Santa Fe Depot, is a six image panorama stitched within Adobe Lightroom.  Focal length was about 12mm and is the probable cause for the slight barrel/bulging effect.
I intend to reshoot the scene with the Sony 16mm lens for comparison purposes.  Assuming we get another clear night sky in the very near future.  Overall, I'm pleased with the lens/adapter combination.  Comments are welcomed.
