I'm looking for a second flash to use both for TTL and off-camera duty. So it must have manual power settings and be compatible with E-TTL II.
Both the 430EX and 550EX can be had for around $200. The 430EX offers faster recycling and one-button tilt/swivel, which the 550EX lacks. The 430EX will also automatically zoom in more to adjust for the 1.6x crop on my 40D (up to its 105mm max zoom).
However, the 550EX is a full stop more powerful and can act as a commander if I get another TTL flash later on. The 550EX uses an older AF light design, so it only works with 5 of the AF points on my 40D.
The 580EX is of course the best in terms of features and performance, but it's also more expensive at around $300.
Which one would you guys pick?
