I have been experimenting with digital SLRs in night photography. I have tried a Olympus E20N and the Pentax *istD, and concluded that each camera is very different. I finally figured out how to reduce the noise in the E20N for long exposures at higher sensitivities and using it's internal noise reduction features. I like the low noise, but due to the noise reduction technique it uses, it's harder to do streak photography. it takes several exposures and does averaging on them, which causes the streaks to have "jumps" in them. I'm still learning how to use my *istD in long expoure modes and have determined that it certainly is noisier than the E20N at the same sensitivity setting.

just want to see whether anyone has used these cameras and wants to share their experiences.

later....
