I have a Nikon F75 and was thinking of buying a SB-28DX speedlight for it.\nThen I was offered a used SB-26 for less then the SB-28DX. I tend to shoot\na lot of nature pictures and a few family weddings/parties. I am also\nthinking of getting a D70 in the next year, will the SB-26 work well with\nthe D70? Any suggestions which one is the better purchase? Thanks.
