Great video! Just a suggestion: You should put the lens test charts side by side in the next video you do comparing other lenses. It would be nice to see both at the same time in addition to you flashing between the two. For example like on the left you'd put the Tamron 17-28mm and then on the right put a mirror image of the same side (as the Tamron) of the Sony 20mm. That way they are right up next to each other. Cheers!
