Bests & Worsts Reviews from Amazon

I've only had my T3i for about 8 months when this came out but I read the details and decided to pre-order. The new T4i just arrived today (body only) and I've been playing around with it all afternoon using my 50mm 1.4 lens. All I can say so far is WOW - I'm very impressed with the upgraded autofocus, the touchscreen, as well as the new focus selection methods. There is a LOT less delay when you move the camera and what you see on the screen in Live Mode. Live Mode is MUCH "snappier" feeling. When you turned on the T3i in Live Mode, it would have a little rectangle you could move around the screen to make sure the camera was focusing on what you wanted. But with the T4i, this system is much more versatile. You can tap the screen to instantly set a focus point, or you can move the little box around (which is much smaller and more precise now - and it will also FOLLOW your focus point when you move the camera around!), or you can allow for a more "general focus" by getting rid of the little box and letting the camera choose how it wants to focus, similar to how it works when using only the viewfinder to take photos. When you do the "general focus", a bunch of little boxes appear on the screen letting you know exactly which parts of the photo are in sharp focus - the T3i did not do this and only relied on the positioning of the focus box. The continuous autofocus during video worked very well on my 50mm 1.4 lens - sure, the focus motor was a little noisy, but if you're taking scenic shots or something where you'll be replacing the audio with music anyway, motor noise is a non-issue. If you're doing interviews where the person is talking into a lav mic, it still won't be an issue because the lav mic will be too far away to pick up the motor noise. Motor noise is only an issue if you're using the built in mic, which I would regard as an "emergency only" mic anyway. So all this means that you do NOT need an STM lens to use continuous autofocus - the main purpose of the STM technology as I understand it is to make autofocus FASTER and QUIET. Video autofocus with my 50mm 1.4 is what I would call "fast enough" - meaning, it is a bit slow compared to a camcorder (and noticeable on-screen), but not so slow that it should distract my viewers from the content too much. The only time continuous autofocus won't serve you very well is in dark rooms where it can't lock on to anything very quickly. My 50mm 1.4 lens hunted for focus in very dark areas so in situations like that I would manual focus. Video is excellent quality as always. If you're used to the T3i video, this is just as stellar and tends to make people and scenes look better than they do in real life (when using the 50mm 1.4 at least) - They've moved the video mode to be part of the on/off switch instead of on the mode dial which is where it was on the T3i. This allows you to pick a mode on the dial and then turn on video straight from there and make use of those settings. So you can do full auto exposure video, full manual exposure video, or Program Mode video very easily. I also love the increased ISO to 12800 and the ability for the camera to take multiple exposures and combine them to help eliminate noise and camera shake. This works very well for my purposes. It's a small thing but something I've not noticed anyone else talking about is how much BETTER the shutter sounds. Somehow it's more satisfying and reminds me of the more expensive cameras. HDR Mode: I've uploaded some of this camera's HDR photos to the image section on this page so you can see how well it did combining 3 photos at 3 different exposures - the T4i can do this in camera with no software needed. It takes 3 quick photos and processes them for a few seconds and then the result is the image you see. The 3 originals do not get saved. To save them, you would have to use manual exposure bracketing which this camera does quite well. When using HDR mode, you only have to worry about getting proper focus and then everything else is taken care of for you. Some of the images can come out looking a little weird, but if you take 2 or 3 different versions at different focal points, you should get at least one that looks very nice and detailed with lighting that doesn't look too cartoony. One thing that surprised me was how, in one of my photos, a car unexpectedly entered the scene while it was taking the 3 shots. The resulting image had NO car at all. Pretty cool. CONS: So far, the only thing I DON'T like about the cam are the buttons - somehow they feel cheaper and more fragile than on the T3i. I'll update this if I discover anything else not up to par. Overall, I love the camera and am very happy with my upgrade over the T3i. I'm really looking forward to seeing what the new STM lenses can do.
