I have my Epic in the car all the time for any kind of shot. I do landscapes and, particularly shots of the grandkids with it. Even when I am using other formats and film I will frequently take some with the little one. I usually load it with kodak consumer 400 iso print film. I also try to remember to turn off the flash when unnecessary. I have used some iso 100 slide film to check accuracy of meter and focus and found no problem. For the price I think it is the best bargain around. I hope I remember to get a spare before they are no longer in production.
Nice little camera -- I've carried mine around with me for a couple of years. The problems have already been noted -- it doesn't retain its settings once its turned off and you can't always control what it chooses to focus on. Because of the latter, I've switched over to a compact Olympus 35RC so I can focus manually.
As mentioned earlier, the Epic is programmed to favor wider apertures, so that while you may get 1/60 at f/8 on a Yashica T4, the Epic will lean towards 1/125 at f/5.6. Some people who use ASA 100 film with this camera come to the conclusion, incorrectly, that the focus is off or the lens isn't sharp. But with faster film (Fuji 800 is almost as good as their 400), it produces great results.
