Not so boring ?

Today's "boring bird" is a greater crested grebe, caught in unusual light. This time I used the 1.4 teleconverter, and found that auto focus was much worse. In some circumstances, for example standing on a floating, but almost still, pontoon, trying to focus on a also floating, but practically stationary bird, in C-mode the AF was a complete failure. In S (single) mode it was better, but clearly the reduced light resulting from adding the teleconverter seriously degrades AF performance. NOTE - due to the activities of the antisocial, amoral morons who flood blogs with comment spam, I've finally got fed up and been forced to deny unregistered comments. You can still comment here, but first you need to register, once only, with Typekey. I hope to make this more transparent when I have time.
