Originally posted by UncleVanya You need a prepared SD card to use the K100D Super. The K100D works without anything except button presses. I use rechargeable AA's in both cameras without issues.
Oh, there's a difference between these two, other than the Super's ability to use the SDM lenses? Maybe that is it- the original is screw-drive only, and cannot AF with lenses having AF motors. I do still have the old original K100D as well. I enjoyed them way back when, but neither has been used for many years.
I too have long had the DA* 200mm though not quite as long as I've had the DA* 50-135mm. There have been some periods of at least two years where one or the other sat unused, and still are mainly used when their advantages are needed. I've used them on numerous camera bodies- the K20D, K-5, K-r, K-5 IIs, K-S2, and the KP, which has seemed to beckon for the quality of these lenses, along with their relative compactness for the large aperture. They're great with the KP, especially for low light conditions, where with their larger aperture, they can provide even more ISO range for the low-noise KP.
