Since you are far more knowledgeable than anyone else here on edig tech; I like to know why you think DM/edig went after Vivitar and why the 4 patents. Would appreciate anyone else opinion as well.

Anyone who has ever done photography should know about Vivitar and their lenses, IMO best known for their lenses. But I find it odd (not complaining at all) that this company is the first one. Would love to see the reason as to this logic.

Thanks to those who have provided with continous info.

Can't wait to see the list conitinue.
