Even though I'll be posting a number of photos to this thread, I'm posting this here, under "Sigma Cameras" since the focus will be on how the SD14 performs through out the available ISO range.
Being inspired by akv's thread where the image was photographed at ISO 1600, I decided to experiment with my SD14 and see exactly what can be expected.
Earlier this morning, as several of my Horses were playing front yard gardener, I went out and shot a series of photos keeping as much possible the same while only varying the ISO through out the 50 to 1600 range. The sky was blue with few clouds, I had my SD14 set to Shutter Speed Priority, Sunlight White Balance, 1/320s Shutter Speed. These photos are pretty much snap shots with the only composition being an attempt to ensure a consistent angle between the Sun and my subject. I specifically chose not to perform post processing in preparing these photos for inclusion just so everyone can see what the SD14 base line performance is. Here are the photos:
ISO 50
ISO 100
ISO 200
ISO 400
ISO 800
ISO 1600, Since my 28mm lens could only go down to f22, I raised the shutter speed to 1/640s
So far so good, no significant noise, and the only obvious difference is a apparent reduction in color saturation.
