My wife and I just took a trip to St Lucia - I came back with hundreds of photos taken but to my suprise, what looked like clear photos through the LCD turn out to be hazy. Not blury but not sharp, just hazy. I have a low end DSLR (Canon T1i) and was using a Sigma 50mm 1.4 as the lens most of the time. We took alot of evening shots in Aperture-priority AE where the ISO was around 1600 shutter speed around 1/20th of a second. I know this camera doesnt do extremly well in dim lit areas - but i thought it would do better than this. Am I expecting to much out of this camera or is it operater error? Could it be the lens? Its a new sigma 50mm so could it need calibrated? Day shots at iso 100 came out looking great however. Any suggestions?
