That is a huge improvement, Jack-

Taking the Exp Comp to EV-0.7 has helped nicely!

Now try a test, as the Jay seems to love your backyard. Increase the ISO, so that shutter speed also gets bumped up, and see if you can achieve greater fine detail.

I think that it would be worth a try.

How does increasing ISO to 400 improve sharpnesss? I always thought it was the reverse? Maybe to stop the movement? It is real important to me to blur the background. Here is one more shot. I cropped in a bit on this one.

Jack, the background blur is a matter of aperture, focal length and distance to subject. Increasing the ISO and thus the shutter speed will not have any affect on background blur. Increasing the shutter speed will freeze small movements. For example in your latest shot the eye is softer than the legs - my guess is the head moved a little. Noise levels at ISO 400 on your pentax should be very slight and the faster shutter speed will compensate for minor head movements and feather movements.

OK... I will try that in the morning when the lighting is right again.

Thanks John & Sarah for the tips... much appreciated!

Jack-

Please keep in mind that with you K-10 you can increase the ISO setting without the usual penalty that you would pay in a small imager, CCD type, digicam. The much larger APS-C imager on your K-10 will handle that jump-up in ISO setting with ease, and not much sign of electronic noise.

OK these two were shot at 400 ISO, 1,500 shutter speed & 6.7 aperture 0.5 step with some cropping too.

Here is a portrait of Western Scrub Blue Jay

I've got to work on my action shots as it is a lot harder to get... but not bad though.

shot at 400 ISO, 1,500 shutter speed & 5.6 aperture 0.5 step with some cropping

Here are some more shots from this morning... action with the Pentax!
(aren't very easy to get)



I really wanted this one as it shows off the blue... I was focusing on the peanut and he came in just in front of it...so it is not perfectly in focus. Oh man... had that been in focus!

Excellent static and action photos, Jack-

They really look much improved.
