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

Recently switched from the EF-530 DG ST (bought by mistake because I wanted an LCD screen) to the EF-610 DG Super. I'm having some issues with flash photography on my Pentax k10D with Sigma flash, which may (but I don't have a Pentax flash to compare and test) stem from some possible incompatibility issues between Pentax body and Sigma flash. The rest of the Sigma is good quality at a reasonable price. The flash looks very solid, solid and professional, its only and only advantage is some "sticky" rubber buttons. I would also appreciate setting the flash at 45 degrees up (for ceiling bounce) which is now 60, 75 and 90 - my favorite bounce setting with other kits is 45 degrees up.
