The inclusion of a 'basic' setting mode in the rebel T3i, which functions like an intelligent automatic mode that optimizes all variables for the perfect picture depending on the background.This means that when in auto mode the rebel T3i will automatically analyze the environment and determine the type of environment you are shooting-portrait, landscape e.t.c.and configure the camera settings to fit the type of environment.The rebel T3i shoot at 3.6fps in burst mode. which is quite slow from my point of view considering the fact that high speed shooting are as quick as ever.the ability of the canon EOS rebel T3i to remotely control off camera flash is another major feature.the rebel t3i uses the built in flash to trigger these off camera flash. this feature takes it another step closer to the canon 60D which is more expensive. when you first see the rebel T3i looks a lot like the canon 60D especially when you have the 18-135mm lens mounted.
The canon EOS rebel T3i also comes with the full HD movie capabilities and audio. there is also a audio input for external mics to be connected for better sound quality. other features include full manual controls, an SDXC card slot,video snapshot mode-which records short movie clips of 5,6,8 seconds and automatically joins them into a movie.
one of the cons of the rebel T3i is that it is has a slow frame rate for shooting sports and might sometimes over expose in bright sunlight.
Even with these few cons the canon EOS rebel T3i is perfect choice for anyone, amateur or professional.
