Hi all! I had a focusing question that I'm hoping someone could answer for me. Right now I shoot with the Canon Rebel t4 with the 85mm 1.2 glass on it(probably counterintuitive being on a low end camera, but at the time, I'd rather spend the money on the lens rather than the camera for right now)..Anyways, like most 85mm, focusing is a challenge and not for the faint of heart. However, I have heard that on top of shooting on MF rather than AF with this lens, I should purchase a new focusing screen for the camera? These are rather inexpensive, but I was just wondering if anybody had any insight on this? Should I get it? does it help a lot? Thank you!
