D lenses are not faster because they're D. some AF lenses were re-released as AF-D lenses and had in the meantime a couple more things revised, so AF *might* be a bit faster on some D lenses. > If you use an SCA 300 system, you don't need the D feature; if you use an > SB-28 or 26 or SCA3000 flash, you do. you don't *need* it, you just will be able to *take advantage* of it if you use one of the mentioned flashes. you won't be able to take advantage of it you use other flashes. actually, the D(istance) information is not used only in flash calculations. it's used always, but it's effect is probably only noticed in flash shots. sorry for the off-topic post. best regards, Fernando Martins Systems Administrator fer@caleida.pt http://fernando.somewhere.net/
