Performance at Grace Lutheran Church in Hendersonville, North Carolina, a thankfully well-lit venue with great acoustics - just a bit congested with the pews starting very close to the musicians. I used the Tamron 28-75 and Canon 70-200 f/4L on a Sigma MC-11 adapter on my Sony A7iii, and as backup, my Sony RX10 iv, especially for it's longer reach when shooting from the balcony. Despite the poorer high ISO noise control on the RX10 iv, I think its images held up very well. (Note that the EXIF display for white balance is wrong. On both cameras I made a custom white balance which yielded 2800K..which for some I switched to 2900K)
