Sigma News & Rumors: Sigma Introduces DP1Q, 150-600mm Sports and Contemporary, Two Teleconverters and Four Filters

After launching the DP2Q, it was forseeable for Sigma to soon announce the remaining DP/SD1 Quattros. Today was the day – this morning, Sigma presented the most wide-angled one of the three DP compacts, namely the DP1Q. The only surprise is the optional CRT finder “LCD Viewfinder LVF-01“ that you can see below. The DP1Q ...
