Something seems wrong with those figures. Only 56 full-resolution (6MP) TIFFs, and yet it has room for 512 small (1.5MP) TIFFs? Should that perhaps be 212? > It has about 9 configuration of Jpeg, ranging from 244 at the best setting > to its software limited 999 images, which is still full resolution, but more > compression. > The quality of the best quality Jpegs is very good indeed, FWIW. So it should be, if you only get 244 of them on a 1GB card; that's 4MB each! That's about 50% larger than the best-quality JPEGs from the Nikon D-100. It's apparent that Pentax are using less agressive compression settings.
