Depth of focus is the "behind the lens" analogue of depth of field.
Whereas depth of field is the depth of the plane of focus in front of
the lens (where the subject of your photograph is), depth of focus is
the depth of the plane *inside* the c

I tested my K10D's focusing accuracy a couple nights ago. I figured it was
fine, but I did it just for the hallibut.
Fishy puns aside, I used my D-FA 100mm f2.8 macro (shot wide open) and it
looks like my camera is spot-on. Are there really any benefits to checking
focus with other lenses if
You stop that right now young man or you'll go blind.

I'v been reading these AF tweaking posts closly, and have to agree with Godfrey.
I'm not going to do anything to my K10D. It seem crisp enough with the
16-45(better that with the istD)and 50-200.
Besides i can screw up a light bulb replacement, so it was a givin.:-)

After seeing all the hubbub with this stuff on DPReview.com, I
decided to leave my camera alone and do the fw 1.11 update. The AF is
close enough and produces excellent results. If I really need
critical focusing, I focus manually and use a focusing magnifier. It
only makes sense if I'm usi

William, I did not follow the whole thread but some at DpReview
managed to hack the header of the firmware allowing one to downgrade
from 1.11 to 1.10 (in fact 1.10 with hacked header) and then official
1.10 firmware.
One may like or dislike the method but thought I should mention the possibility.

Ok, it's still light enough here that I was able to do some more testing.
I put the 14/2.8 on the camera and did a focus test with it.
Totally out of whack, though in the same direction as I was moving with the
31mm.
So, I did another adjust until the 14 looked good, and tried again with the
31.

It doesn't necessarrily lack it, but they changed the way you get to it to

Hi:
Bravery overcame foolishness, and I decided to check how accurate my K10 was
for focus accuracy.
It turns out, not very.
So, armed with the instructions and a focus chart I downloaded a while back,
decided to adjust the camera.
Now my camera's AF focuses better.
Interestingly, I could see no
