It makes me wonder if TC's really work.
Most certainly they do, although the prior TC's from Pentax, excluding the
1.7, required manual focusing (A-1.4 X-S, A-1.4 X-L, A-2.0 X-S and A-2.0
X-L).
I've used them extensively on most of my Pentax lenses and am very pleased
with the results. So far, I've used the new HD-DA AF rear converter 1.4X AW
on most of my Pentax lenses and have found it worked flawlessly.
The two bird image BTW, appears to have an issue with camera movement as
opposed to focusing.
Can't help you with the bird.

They don't look too bad to me, Igor. I wonder if setting the FL would have
made much difference?
I recently took some shots of a Saddlebill Stork & chick using my HD
55-300 without & with the 1.7x AF. I set the FL to 500mm. The range is
about 80m. The shot with the 1.7x is cropped less than the one without &
is definitely a bit degraded. It makes me wonder if TC's really work.

Scroll L for the 500.

Doh!

I keep forgetting that SMC Pentax-F 1.7x AF Adapter is seen as an "A" type
of lens by the camera, and no information about the focal length is
transmitted to the camera.
Since my only "A"-type of lens used (not counting converters) is the
Samyang's 8mm-fisheye, it is what remains set for the focal length for the
shake reduction.
Today, I saw a bird (heron or crane?) in our subdivision (or heron?), and
came to photograph it. I put the 1.7 adapter in front of the 60-250 lens,
but forgot to dial for the SR.
While I had to shoot while holding the camera, I was relying in
part on the SR. The result is underwhelming...
... and now I am recalling that I've head this happening to me about a
year ago.
Doh!
BTW, maybe the resident experts could tell me if this is a heron (grey
heron?) or something else?
The first photo is ok as it was taken without the adapter:

Here is the best of those taken with the adapter:

Thank you,
