Dilemma

In my yoof, I did a lot of concert photography. Last night while I sat through PSB @ DMH, half of my brain couldn't help yearning for the a7RII with the 70-300mm to see how it would perform in comparison to my old Pentax K1000 and HP5, but the other half wanted to sit there and be in the moment, so I snapped a couple of social media bragging shots during the first song then just enjoyed the show.
