A rare day with sun so I took the DFA 150-450mm to the "Spinnies" (nr Penrhyn Castle), along with a
sigma 400mm MC, and a
tamron "Nestar" 400mm f6.9.
DFA, birds at the feeders, K3 f7.1.
I had quite a few missed focus shots - focussed on the feeder not the bird.
The kingfisher was prominent, but not close. This was my best long range effort with the DFA, full size 1:1 crop.
When the kingfisher moved into the bush the branches were fooling AF so I had to use MF, so I took careful shots using focus with magnification in LV, 2 secs timer, and I was reviewing the images and trying to fine tune the focus based on the review. Then I took the same shots with the sigma (f10, second) and the tamron (f11, bottom). Not a fair comparison, the kingfisher wasn't in the same position for the tamron (~ 5m closer).
And with the tamron on the K3 I missed the moment the kingfisher landed momentarily on a post in front of the hide... ah well next time.
PS eyebolt works good.
