This thread is lacking in activity. I see my last post was 1st June and that's only two posts up! Perhaps, Sigma cameras are in the wilderness. I still think their camera make amazing images if used in the conditions they like but they get such a bad press. Hopefully, if the full frame Foveon is released it will give Sigma a boost. I guess the bad press is because they need to be used at ISO100 and today people don't want that constraint.
Here is Brailes church, Warwickshire with some nasty weather approaching. Sigma SD Quattro H with the 135mm Art lens.
And a bowl of ornamental Qunices from the garden. Chaenomeles japonica for making quince jelly. Yum. dp0 Quattro using SFD mode on a tripod.
