Hi to all I am new to Sigma DP Merrill series. I used to be using Ricoh GRD3 and GRD4. I am a foodie and love to use the 1cam macro with my GRD camera. If I am planning to do the same thing, may I know Which DP Merrill should I get, in order to get decent food macro pictures ? Please kindly advise ASAP. Many thanks in advance.
