To be honest, I don't care which camera was used to take the pictures.It is important to me that the pictures are authentic and have not been stolen. There should also be an honest answer to honest questions!
I can't imagine that anyone on Hive would be permanently successful with pirate copies. By the way, one method to find out if your pictures have been stolen is the Google search engine. Everyone can select images from the top right corner and drag and drop an image into the search engine. Google looks whether identical or similar material can be found.
