Originally posted by gokenin I have been thinking of switching to one of the camera bodies that have a pentaprism instead of a pentamirror since i have heard that they have a brighter viewfinder and may make manual focus lens easier to use.
Marc is actually right since he has been using the K200D.
If you want the pentaprism instead, then a good deal and upgrade would be the K20D since it would still retain the weathersealing, give you the pentaprism, it would also give you AF adjustments for the lenses you have and the K20D is now a lot cheaper when it was first introduced and probably the same price now as when your K200D was brand new.
Going for the K-7 wouldn't be too much of an upgrade lest you want the HD video and faster FPS and AF speed.
