It's not released yet, but some earlier help files are here....

RAW profiles for the K-5, K-R and K-x are here

You could install the last retail version 3.9 but it runs on Java
and Java doesn't support old applications very well

TC posted RMSD Next Day.

Sorry not been online since yesterday. The TC is Sold and
I've received payment and thanked Papa_Lazarou by PM.

I've just packed the TC up and will be posting it in about
an hour so Papa_Lazarou should receive it tomorrow.

Thanks for the interest Kea828

I would never have thought it was the Tamron 17-50mm
The bokeh looks very similar to old roll film cameras of the 20's - 50's
similar to the Kertesz look

Nice set of photographs... even got a plane in the first

The bokeh on the Spiral Staircase is really good
What lens did you use? Sigma 70-200mm ?

I don't think the FL matters too much with reasonably high speeds.
There is a graph on the US Forum somewhere and some comments about
not being able to enter the FL with most TC's. The older MF
Pentax-A TC's do allow it, but I've not noticed any difference.
I wouldn't bother too much about it. I wonder if Canikon lenses
with built into the lens SR are able to allow for a TC? Unlikely.

The 1.4x probably lets about 1/3rd more light through which
possibly helps SDM for some reason, although the Sigma 150-500mm
works and that's darker at something like f/6.3.

I wouldn't know if the 200mm SDM will work or not with the
f/1.7 maybe johnwhit knows?

It's possible that the K-5ii will work better than my K-5
due to the better low light AF.

LightZone at one time a retail competitor to PS will shortly
be available for for FREE for Windows, Linux and eventually
Mac.

The Windows version has been through Beta testing and is due to
be released as soon as they sort out a compile problem

The website is a bit messy at present, but it's being
re-written.

The shot above of the building/folly should have complete
EXIF data. Good TC's just pass the data straight through so
the focal length will be whatever the lens is zoomed to.

In the case of the Sigma 150-500mm the shake reduction is
built into the lens and I was amazed how steady it made the
image on the building/folly shot.

This shot was with the Pentax 55-300mm with the Pentax K-5
SR accidentally set to 28mm when the lens was probably at
about 250mm It's not made much difference...
The TC in this case was purely manual it didn't pass
the lens info (Pentax 1.4X-S A series TC ) No AF either.
That's why I've been looking for a good AF fully auto
TC like this Jessops one that passes all the info and
allows AF.

There are a couple at the end of the link above. I tagged them
on to the 55-300 test thread rather than start another.

https://www.pentaxuser.com/forum/topic/test---pentax-da-smc-55-300mm-f-4-5-8-ed-...

I was amazed this one worked. The 150-500mm was right out at 500mm
+1.7x TC = 850mm (but the 500mm is probably less than 500 )
It was shaking handheld at 1/125th f/8 400ISO I was going to
leave it, but the viewfinder went very steady so I fired off
a shot on AF-S. I was amazed that it was so sharp and even the
corner of the roof is sharp and the colours were spot on. AF is
the same as without the TC.

To be honest I only tried it handheld on the DA*300 partly
because I never use a tripod with that lens. I'll try it on a
tripod tomorrow. The light is also a lot brighter now than
when I tried it.
