Several weeks ago an acquaintance reached out to me and asked me to photograph her wedding. I accepted with trepidation and decided to say "yes", but planned on shooting it with my Sony A7iii. I bought the Sony HVL-F60RM flash, "just in case the venue was too dark", even though the A7iii handles noise very nicely at the higher ISOs required in low-light areas, I prefer the better color I get with lower ISOs and the flash will allow that.
Since the RX10 iv is great with this flash, I will bring it as a back up to the A7iii which I will use because of its better dynamic range...and I will deal with the skin color in PPing.
