what is the difference of canon t5 from canon t4?
Personally, I'm not sure about the exact differences between T4i vs. T5i due to the fact that I was upgrading from T2i to t5i.
But after reading about some design flaws and left-out features on the T4i, I waited to buy the latest model.
I was also expecting major upgrades on the video shooting capabilities (faster focus), especially if the camera is paired with STM lens. This was one of my major goal with this purchase.
And I believe Canon delivered on this promise.
Other improvements from T4i...reading from different sources that they really improved on is live shooting mode...a feature personally not really interested in.
Esthetically improved a material flaw on T4i (grips getting a whitish color after some use).
I really like the new Video/Camera/OFF switch, which wasn't the same on the T2i.
So far I'm totally satisfied with both video and camera quality even though I didn't have a chance yet to fully explore every feature and to have really deep understanding of the new features.
I hope this help. There are many specialty magazines which are discussing in depth the differences.
All the best and good luck.
