Do you really need a flash?

What is ETTL, my flash unit support flash ETTL II

E-TTL (Evaluative-Through The Lens) is a Canon EOS flash exposure system that uses a brief pre-flash before the main flash in order to obtain a more correct exposure.

Basically a software improvement on E-TTL, E-TTL II is now a standard in all EOS cameras introduced with or after the Canon EOS-1D Mark II (2004). E-TTL II is body-dependent and therefore can use existing E-TTL flash units and EF lenses.

One question. Does it support 2nd curtain sync? I know some 3rd party (e.g. Sunpak) doesn't.
