using Flash with auto iso.

Will the k5iis automatically bring down the iso to compensate for the Flash in av mode?

If it is anything like the k-r then it won't do exactly what you want it to do. I find that in Aperture priority mode (assuming you are using P-TTL here) the camera tends to push the shutter speed down (1/10 to 1/60) instead of pushing the ISO up. So you don't get consistent results picture to picture. Your first shot might be 1/30 at ISO 200 and the next might be 1/100 at ISO 800. So you end up getting a weird mix of ambient / flash from one pic to the next and sometimes motion trails if it pushes the shutter speed too low. I would recommend that you pick an ISO that you are happy with instead of using auto mode, at least if you want to get more consistent results with your flash.

The camera will bring the ISO down to compensate for ambient lighting without the flash (i.e. a dark room will result in the camera using close to your maximum specified ISO, e.g. ISO6400/12800) and then the flash will adjust it's output for the ISO.
