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.

Subject: Shake reduction - Doh! (And PESO - heron?)
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,
