Allows multiple functions with both older and latest EOS bodies

None. Abit noisy that's all.

Its a great flash, and definately worth the savings over 380EX.

The new E-TTL with EOS3

None at all

The exposure is much much better than the 540EZ on the EOS3 and EOS50e. Thanks to the E-TTL metering. I would say it is a close match to the D-metering of the Nikons. Still as heavy as the old 540, some people may find the SB-28 a much lighter choice than the Canon. However, I must admit that all the powerful Canon flashes make a louder 'phaser' sound when charging, especially in a quiet environment like a wedding in a church.

Haven't got problems yet, thank God.
