Review on 📸 Sigma EF-530 DG ST Electronic Flash: Premium Lighting Solution for Pentax and Samsung DSLRs by Tim Evans

What is this thing supposed to do. It only has 3 settings 1. ttl 2. high 3. low. I'm used to manual flashes so I went with ttl. As I shoot Pentax, my third party options are very limited. There isn't even a slave mode here. This is the only flash that keeps showing that the shutter curtain is out of sync. Not a fan, he just sits in my camera bag and mocks me.
