Re: settings for tests?

thanks for your investigations and comments. I'll get back to it later on.

This afternoon I may have the opportunity to shoot a K-5 II or K-5 IIs.

Do I have to observe certain settings regarding dark frame subtraction or dynamic range expansion etc.?

Kerusker, Dark Frame Subtraction (DFS) when it is used either by forcing or automatically might make a difference as in the subtraction of a black "lens cap" image from a normal image might result in zero black levels without any compensaton.  Highlight Compensation shouldn't make any difference as it is still using a basic capture other than for metering the exposure as if the ISO was set one stop higher; there is a slight question that the point at which the switch over to dark frame subtraction might start at ISO 3200 rather than 1600 as is usual.
