I have not attempted to capture birds in flight, but I wonder if you could try increasing the ISO. The Pentax 16MP sensor cameras have very good ISO performance, producing little noise up to at least ISO 1600 in good lighting. You could try e.g. ISO 800 and then use e.g. f/16, to give a greater depth of field for a bit more focus leeway.

I'm sure an experienced member will tell you if I am writing rubbish here! :

Cheers.

Nigel, I would be pleased if I had captured any of these compositions. The colours are mostly as I like them, but I think I would slightly reduce the red in 5, 6 and 8. Although, of course, I realise that the scenes might have had the appearance shown here at the time you shot them.

Cheers.

It certainly seems to be flourishing, John. Have you got a shot in which we can see a trapped fly?

Cheers.

I like these images Nigel, and particularly the impression of depth in 1 and 6. In 2 the sky looks a rather unnatural blue colour to me - I would expect a shade more towards cyan, as in 1 and 3.

Cheers.

Yes, Patrick - K-5II Custom Menu C4/26 "AF Fine Adjustment", but don't know if it works for that Sigma lens.

Cheers.

Did you use a tripod? Shutter speed at 1/125sec I would say was too slow otherwise.
This comment is puzzling - am I missing something?. Following the guideline - shutter speed faster than 1/(focal length x 1.5) - a speed of 1/125s without tripod gives the photographer at least 2 stops benefit. In addition, SR was On, so that should give a total hand-held shooting benefit well in excess of 4 stops.

Is it possible that the lens requires focus calibration?

Cheers.

Thank you Lenny and John.

Thank you Lenny, that makes sense, but does it also suggest that it might be less suitable for someone like me who wears spectacles, as they keep the eye further from viewfinder?

Cheers.

It would be interesting to hear from someone who uses one of those eyecups in Bill's link - 1.2x magnification doesn't seem much but does it significantly improve the view?

Cheers.

If the aim is to portray the real scene then, for me, the sky should not have a blue colour cast. I think that the colours, brightness and contrast of everything below the sky are as I would expect to see them. In my view, blending a more dramatic B&W conversion of the sky with the rest of the original colour version, gives a more realistic image.

Cheers.
