I've been shooting the DP3 Quattro (and other cameras for trips), comparing settings, experimenting, etc. Here is a plant called Cineraria, shot RAW at f/7.1 1/100 ISO200 processed SPP6.8.3 same settings as the next photo to it on flickr, same settings, same processing shot at f/5. Here's the f/7.1 version. Generally I hate having a blurry foreground, but I like the way the in-focus blossoms arch around the center focal point slightly in back of the blurry blossom....

By the way, I've just had to buy and set up a new computer, newly added SPP6.8.3 instead of the SPP6.8.2 which I have used on my old computer. Does anyone else experience much slower processing on SPP6.8.3? I have 16GB RAM in both computers.
I find the white peonies are the hardest to capture. This is one, early evening, NO BREEZE, significant so I can get down to 1/80 and still be sharp. Focus point is on blossom at left. DP3Quattro, ISO125 1/80 f/3.2 processed in SPP6.8.2 and cropped in Canon's DPP4. (The Canon RAW processor is handy for cropping Sigma photos, since SPP doesn't have a crop tool but Canon does, and I use DPP4 for my Canon 5DS photos). I've been experimenting with ISOs, apertures, shutter, on both cameras. Linked to flickr, more photos online
