If you go purely by model numbers, the T5i is an upgrade over the T4i, but when you look at performance there isn't much here to warrant calling it an upgrade. As to be expected from Canon, the T5i takes good photos, with Digital Photography Review noting its "high image quality with good balance between detail and noise." Digital Camera Review also felt the T5i did well in the video department, saying it was "quite good." From the outside much hasn't changed, and Photography Blog says the T5i and T4i look "virtually identical." They also say that in spite of its smaller size and narrow grip, "the size and shape of the grip proved not to be too much of an annoyance." The major change with the T5i is the lens that Canon ships with the kit, and as it stands, it doesn't do anything to drastically increase image quality over the T4i. All told, the T5i is still a solid entry-level performer, but for those who already have the T4i, or even the T3i, there is no reason to rush out and upgrade.
