Anyone here use there Sigma for infra red? One of my main reasons for buying an sd14 was it's infra red capabilities.However I could'nt quite bring myself to remove the filter. More than happy with the 'normal' images I'm getting I decided to look at other cameras....the sd14 does not have live view,which really helps with ir preview. the smaller 'point and shoot' Sigmas do however,and I'm told that the foveon sensor is ideal for ir...So,anyone have a converted Sigma? Any model, would be very interested in hearing from you. Thanks,Martin.
