So, I am back to report a few things I have tried over the past several days:
Using AF-S on stationary subjects :
TAv, spot metering, spot AF.
1. As long as the bird (my subject) doesn't move, I am getting better "keeper rate" at roughly 50%. Not great though.
2. As long as the contrast is
high, the subject will more often be in focus. With subjects "blending" with the background, the results are atrocious.
3. Definitely doing better at f5.6-8.0 although I thought that this K3 would at least behave better at f4.0-5.0. (like it did with the K5).
4.
For BIF in AF-S ... as long as the subject is (very)distant AND with high contrast, it is OK. When the subject is closer and I have to pan ... forget it!
I will post some pics that I have taken today to show what mess this caused. A couple of harriers chasing one another at reasonable distance and this was with great weather: dry, sunny. The pics look OK uncropped but they sure are "soft" when viewed at 50% cropping. I will try to post those tomorrow.
Again, I used to be able to get along quite well with the K5 (and DA*300/4) for BIF shots ... not anymore; this camera is giving me a headache!
So, this means that I have to follow the advice of
audiobomber and start using the AF-C mode.
I've tried this in the past with the K5 but because the results were so poor, I totally ignored this feature for the K3.
On the other hand, when eventually I nail the focus, the images are extremely detailed and vibrant !
So, back tomorrow with some pics.
Cheers!
