Sorry if this has already been discussed. For a 20D, which of the two flashes is a better option? My main use will be people photography - weddings, portraits, etc.



Thanks very much

I cant speak for the 430 as I have never used it. I do have the Sigma Super and it compliments the 20D very well. It is extremely close in all aspects to the 550EX.

Plus I bounced it all the way across a marble floor when a client knocked my tripod and it survived well.

Best thing to do is go to a shop and try them both on your 20D.

Cheers,

Nick

I've got the Sigma 500DG Super, and it is a very good flash, all the features and power of the 550ex for the price of the 420ex.
The Sigma manual is a bit rough, but then so was my Canon manuals for the 420ez and 430ez flashes.
Best to read the included manual and if things don't make sense ask here, lots have gone before. :-) and can help.

Peter.

The manual is now on-line
FYI - http://www.sigma-photo.com/flashes/f...ls.asp?id=3257

IMHO... It all depends on the street price of the 430EX and its features improvements over the 420EX, beside the GN which is not yet known - The table could turn with the new model (or the price of the EF 500 DG Super has to erode further)
