EG: Most IR shots of grass, trees, etc shows the greens as white.
Your images, good though they are, don't quite portray that.

. . . nothing.
May we know which lens it is? It may be one that has known issues that somebody might no of.
Is it maybe a zoom that suffers from barrel creep, that is, it changes focus when pointed up or down?
Does it rattle when you shake it?

Surely the inaccuracy of the actual point of focus is down to the mechanical tolerances of the mirror adjustment and placement of the focus sensors.
So with no mirror and the focusing being done by the image sensor should eliminate some of these issues.

The software will not tell you what setting you need to enter into the camera to put the AF right, you'll still need to experiment to get it correct.
If you ware varifocal glasses as I do you my realise that something like this could be very useful

I usually just wait for another person to tell me " it's a bit soft "

[quote:3496ace15f="JohnX"]I guess folks can look up the corresponding figures in their K5 and K5II manuals.
The K-5 is EV-1 to 18, the K-5 II is EV-3 to 18, but I can find no reference to aperture that this refers to.
All I know is that the K-5 II is awesome at focusing in very low light with a f2.8 lens.
Comment by Mannesty posted on K5II - centre focus point - AF at f2.8 - What? at 27/04/2013 - 10:03
When using these test charts do you focus from the minimum focus distance of the lens ...
The instructions say "minimum focus distance, then back a bit".
