Thanks for that, MedicineMan404. The conditions really came together that night and the lens did its part quite well.
I'm so happy with Tamron that I just picked up the 35/1.4 and will adapt it to Sony. And of course, I'm considering a few longer zooms like the 28-200 & 70-300.
Few action shots from last weekend.... I took it along on my MTB trip in Salida, CO. The lens is a bit too big to carry regularly though, so I'll probably use my 18-135mm in crop mode on my A7iii most of the time.
