SIGMA ELECTRONIC FLASH EF-610 DG ST EO-ETTLⅡ This is a high-powered strobe flash from Sigma ◡̈ (For Canon) I bought it because I was told it would be needed for work, but I rarely used it and have stored it in a dehumidified storage. It has been used very few times and is in beautiful condition with no scratches or stains, so I will sell it to someone who will use it ◡̈ One owner & operation confirmed before listing EF-610 DG ST ED-ETTLⅡ Body + flash stand + dedicated pouch + original box Instruction manual + warranty (warranty period has expired)
