>Not that several camera makers make EF mount cameras and third party lens makers make EF mount lenses, like Yongnuo, Samyang, Schneider, Sigma, Tamron, Tokina, Cosina and Carl Zeiss. They are being discontinued at these manufacturers as well. I was looking into validating a range of EF mount lenses for a specific application a couple years ago and for every vendor we talked to, they indicated that some of their lenses were either newly discontinued or soon to be discontinued. No matter what the lens manufacturers are saying, I'm confident that they will slowly be discontinuing their DSLR lines over the coming few years.
