Originally posted by marquis1955 Thank you for the fast response, if I understand properly on my K30 if the lens has an A setting, I must have auto ISO off, but don't necessarily have to be in Manual mode ? And if I understand also if I have A setting on the lens I don't need to change my "Using Aperture Ring" to permitted in the menu ?
Auto-ISO only has to be turned off to use M mode on the K-30. This is because the K-30 inherited its firmware from the K-01 which uses Auto-ISO in M mode as a pseudo-TAv mode. The K-30 has 2 eDials and a TAv mode so it doesn't need to do this. On all other Pentax cameras Auto-ISO is automatically turned off in M mode.
If the lens has an A setting you do not need to set "Using Aperture Ring" to permitted unless you want to set the aperture with the ring instead of the camera.
