A:Answerthe auto focus of this lens is very slow because this is a third party lens, and you need a bright light or video light to get the focus right.. what i did is use it in manual mode.. use your cam’s eye piece... or you can upgrade your lens to f2.8 or below...
A:AnswerWhile i can't be totally sure, the EOS lens mount hasn't changed in decades. I have the Ti5 Rebel and at one time owned a Ti1 and a Ti3. The lenses I have fit all three. So I'd be very surprised if it didn't. BTW this lens fitted with a circular polarizer has become my main lens.
A:AnswerYes. The Canon version of this lens has an EF-S mount. This means it will fit any camera with an EF-S mount. The Canon T5 has the EF-S mount and can also accept EF mount lenses.
