The second ‘designed for the D40′ accessory today is the SB-400 Speedlight, a compact yet powerful external flash with a tilting front (horizontal, 60, 75 and 90 degrees). This unit has a guide number of 21 (m at ISO 100 at 18mm) and has a shooting distance of 60 cm to 20 m (2 to 66 ft).

Pero if ako ang tatanungin? I’ll stick to SB600 (pag may budget SB800) at least flexible yung ulo and GN (ISO 100) is 98 ft, 30m @ 35mm … not sure yet how much yung street price sa Pinas since it will be released worldwide by next month, December ‘06 … looking the design you’ll see that this is kewl for a landscape shot not with portrait wherein the advantage of SB600 comes in … wais ang marketing, hehehe … just our2cents
