I've not been using my K100D for a few months, as I tend to only use it for colour and I've been shooting only b/w over the winter. Then I remember, while reviewing some of the other cameras I've had over the last two or three years, that a few others are/were 6MP.
These were made with a FujiFilm FinePix F810 about a year ago. Very impressive lens and Super CCD sensor combo, if overall I found it a rather quirky and not particularly intuitive camera to use, with way too many buttons!
Thanks for looking!
