We had a nice huntsman spider sitting on on of our walls (in the house). I took the opportunity to take a few images for a stack. I stacked the images in camera using focus stacking. I then took the raw files and stacked them in photoshop with and without using DXO pureraw4 on the images. No other editing of the images was done.

The things I noticed were
1) the in camera stack is cropped significantly more than the externally processed images;
2) the noise in the in camera stack is noticeably reduced compared to the direct stacking of the camera raw images (though this might not be as noticeable here as on the computer screen) and DXO pureraw rectifies this;
3) the detail in the externally processed stacks is noticeably higher than the in camera stack as should be evident in the cropped images (though the in camera stack has managed to keep the ends of some hairs in focus). I made no adjustments to the photoshop stacking masks so I probably could have improved this aspect of the photoshop stacks.
These were taken using the 90mm macro and other than the slightly tacky feel of the focus ring, it is a much nicer lens to use than the 60mm (which has a silky focus ring).
My wish for the OM focus bracketing is that it would allow me to specify how many focus steps I want to start in front of the current focus point (like focus stacking does - though without my control) and a choice to do a stack in the camera stack or not with the bracketing (i.e. not separate menu selections in the camera for focus stack and focus bracket). I like that stacks take steps in front of the subject but dislike the speed or output of the stacks - it is particularly annoying if you are taking multiple sets of images of something that moves from time to time and you have to wait while the stack fails before you can have another shot.
