Sorry to hear about this. Stick around AuraTodd and move onto
something else...... something new.

CiF works exactly as defined on page 136 of the K-5 manual so
what you are talking about isn't CiF

I think we are splitting hairs which seems to be
the norm for this forum so I'm finished with this
thread.

Press shutter half-way.
Move in until you get a beep and CiF lit.
Re compose.
Shoot.

If you look at the video you will see that there is a CiF range
just like a DOF range. I set mine up with an adjustment value so
that as I move in on a bug the shutter trips at the beginning of
the range.

Easier to set up using a focus rack with a mm scale on it and a
lens that performs well wide open.

Some notes from a FA 50mm f/2.8 Macro on a K-5
Daylight LED lighting
Distance sensor to target 770mm
Rack at +/-0mm is in focus.

+2 Adjustment set on camera
Beeps at -7mm and +9mm so +2 is OK for general/stopped down use.
For more accurate focus set rack halway between the two values.

Change Adjustment for it to trigger (CiF) at -7mm and fire as
the camera moves in. +5 Adjustment seems OK.

Note: The beep/green light works with any lens with the
camera set to MF. CiF only works with MF lenses or lenses
with a MF/AF switch and the camera set to AF.S

Post a spoiler you mean
Then I would have people complaining that they had been trying
to figure out the green dot since the ME-F came out 32 years ago
and they would have nailed it in another year

This video might give you a few hints.....

I remember several camera shops just like that, except
they didn't have any Leica's

[quote:3496ace15f="Smeggypants"]The only lenses I've found that lie outside the +/-10 range is some old manual focus lenses.
What is the point of adjusting the phase detect AF correction for manual focus lenses ?
"Capture in focus" - press the shutter release then slowly alter focus and when focus is detected the shutter will release.
I'd always found that to be a hit-and-miss affair with manual lenses both on the K-7 and K-5ii. A good focusing screen is much easier.[/quote]It's actually very accurate, but you have to know more about what
is meant by and how to focus a camera. I've seen Canikon users who
seem to understand but Pentax users expect it all to be automatic
and the camera do everything.
