you mean fine JPG compression? You should use the best quality images you can get out of the camera so do use fine. Best is to shoot RAW and either convert to JPG at maximum quality or TIFF for even less compression artifacts. I am not sure if it is worth it converting to TIFF. Have anyone seen a noticeable difference?
I use a full frame Nikon D800 camera with 36,6 mpix resolution and agisoft handles the images with no problem.
