Most of these images were taken at f2.8 or f4. Lighting was terrible and I had to take at least 3 to 5 images of all my subjects. I don't know about you but I find it impossible to tell if an image is sharp or not when reviewing the images on the LCD. It's just too small. Small movement when taking the shot cannot be seen and I tend not to delete any images in-camera. I just wait until I get home and look at them on the montor. SD cards are really cheap these days and I just take a handful with me when I go out. They don't really increase the weight you have to carry around with you.
