Not sure is it batch related, I pre order mine on 22nd and collection was today 29th September , as pre order date for my country is 22nd and official launch date was 29th sept. Before my collection I went and check out all of the demo units in the retailers shop. Surprisingly none of the pros have the rough / sharp edge as mention. ( I did not check the none pros ) It’s smooth transition all the way, and there is no micro damage the frame has consistent colour (natural ti for me ) and no dust in the lense as well.
Ngl the more I read all the reports and feedback. The more I think is batch issue, same for the overheating issue I guess.
