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

I've had this flash for almost a year now. That's a great flash. The only problem I have is that there is no indication when the battery is low. I mean, it lasts a long time, but when the battery is low it just doesn't work or takes a long time to charge. Otherwise it's a good flash.
