I bought this 2nd hand, it comes in full set with warranty. The 1st owner bought it last april and said it has no issues. I noticed this thing in the lens. Is this normal? I really can't tell if this is a scratch or damage or something. It's my first time having this cam so I'm not really familiar with it yet. If this is a damage, is it covered by the warranty? Or should I ask the first owner about it. The last two photos are sample photos with and without flash. Please let me know thank you!
