Hello! I'm brand new to the film scene and just recently got my first DSLR. It's a Canon Rebel T4i. I did some research to determine the first lenses I should buy and purchased a Canon EFS 18-55 mm and a Canon FD 50mm with the adapter. The 18-55 mm works great and I've had a blast messing around with it, but the 50mm is a nightmare and is basically useless. I can only get it to focus on tiny portions and have to hold it extremely close to the subject. I was told this lens was good for vlogging, but as it is now, I can't use it for vlogging or anything else for that matter. Am I doing something wrong? Or did I misread what kind of lense to buy? Is it a compatibility problem with my camera? Please help!!!
