Just finished a 14-hour wedding yesterday using T3i for the first time. I upgraded two of my T2i to two T3i for these reasons (I don't want to deal with the ML heck),
- Manual audio control
- 3x Digital zoom
- Articulating LCD screen
I am so please to report,
I have RODE VideoMic connected to the camera. One time I didn't plug in the cord tight enough. Some of the clips has one side audio, and some where just empty. Now I am able to view the audio meter display through the Menu screen and be able to turn off audio AGC. The sound recorded in T2i gets worst when picking up sound from loud speakers. Now I can adjust the recording level to avoid any clipping.
The 3x Digital Zoom is the best feature (sorry 60D owners . It requires a few button clicks to get to it. However, I already trained myself to switch quickly between normal setting and digital zoom. With the 3X digital zoom, I can get good range even with my Sigma 17-50mm F2.8 lens, from wide angle view to close ups. For example, at Cake Cutting, I can get a full view including the bride and groom and the cake table. Then I can switch to a good close up when they feed each other. Very happy with the result.
The articulating LCD screen makes shooting a lot easier. Doesn't have to be on eye-level all the time. I can raise the tripod center column goes above everybody's head and still be able to see the LCD screen without much guessing. When I use the slider, I have rotate the LCD screen to the angle where I can see the view clearly.
Lastly, there isn't any single incident of overheating all day at all.
So my next step is to sell my third T2i and replace it with another T3i on Merlin. I am thinking of selling my Canon 70-200mm F2.8L. =)
