A very nice camera. It takes great pictures. I bought it when it was on sale for Christmas 2012. The biggest difference between this and the T3i is the touchscreen. I wasnt going to pay extra for what I viewed as a gimmick, but due the sale the T4i and T3i were the same price, so I got the newer model. I must say, I use the touchscreen extensively and find it more intuitive and faster than the standard buttons for changing advanced settings. It also makes checking shots faster and easier with pinch to zoom and drag to pan. I can verify good lighting, sharp focus, proper depth of field, and check for blinks and smiles very quickly. Most of the buttons are in the same location as earlier Canon digital rebels. The mode knob works mostly the same way I remember, dating back to even film cameras (Although, I rarely use anything over than Aperture (Av) and Manual (M)). The power switch is crisp and easy switch on an off without looking. The power switch also has a video setting which implies that you can use the any of the modes with video shooting. Although this is technically true, it doesnt work like you would expect: Manual works fine, but shooting video in Av mode, does not let you set a fixed aperture and then auto-meter the shutter speed. Video Av mode works more or less like video (P) mode. It is good in low light; much better than my previous DSLR: the Rebel XT, which only goes up to ISO1600 (the T4i goes up to ISO 12800, and technically has a 25600, but that is very grainy). The T4i can deliver similar picture quality to my XT in 8x lower light. However, even with an 8x improvement it does still have trouble in doors without a flash, especially in a dimly light room. I normally use an external flash bounced off the ceiling when shooting indoors. The picture quality of still photos and video are both great. This camera has a good high quality APS-C sensor. It doesnt take as good of pictures of a professional grade full frame camera, but it does take really good pictures, especially in good light. The biggest draw back to this camera is the horrible sensor based (contrast detection) autofocus in live view and video modes. It literally takes 5 seconds to focus on something, even when the focus is close to start with. In the video mode, you can be shooting from a tripod on a fixed object and the autofocus will randomly decide that the sharp focus it has isnt good enough and start hunting. It will hunt until the object is a complete blur and then return back to where it started. The autofocus is unusable for videos. I shoot all my videos in manual focus. I sometimes have to throw shots out because I screwed but the manual focus, but that is better than throwing out all shots because the autofocus decides to hunt. The manual focus also solves the problem of the microphone picking up the sound of the focus motor: manual focus is always quiet. Note that the same lenses that have horrible performance with live view and video focusing work amazingly well with the phase detection autofocus build into the view finder. The phase detection in the view finder always goes straight to ultra sharp focus in less than a second and stays there. Therefore, I always do my still shooting through the viewfinder whenever I can. Sometimes I hold the camera up and use live view to shoot a shot from above, in which case I just hold the shutter button down for 5 to 10 seconds until the live view finally focuses and takes the picture. If I take a second picture, the live view autofocus takes another 5 to 10 seconds EVEN THOUGH IT STARTED IN FOCUS. And again, I always use manual focus for video. I have never tried an STM lens, maybe they are better, but I am not going buy a whole new set of lenses simply because Canon botched the live view autofocus. I havent spent much time with the T5i, but as far I can tell, the biggest upgrade was changing the 4 to a 5. I am very happy that I bought this camera and since I dont shot a ton of video and normally use the viewfinder, I can live with its quirks. I have logged many happy hours of shooting, and plan on many more. If it was somehow damaged, I would buy another to replace it. Otherwise, I will probably not upgrade until Canon fixes the liveview/video autofocus in a Rebel. I am hoping the dual pixel autofocus in the 70D turns out to fix this issue and comes out in a rebel in 2-3 years. Fingers crossed.
