ideally one should set it each time to the focal length you are using for the shot (in this case multiplied by 1.7 because of the t/c).
In practice that is a bit of a chore so I set it to the lower end of the range i expected to use. I anticipated using the 200-250 range for shots of the Pheasant so allowing for the t/c I entered 350 as my S/R focal length. If you are going to miss on the input length it is best to be on the low side as a longer input focal length will cause the camera to overcompensate and actually induce shake.

The autofocus on mine can be a bit lazy, sometimes need to wake it up by turning the focus ring.

Sensible hat off: get the 1.2 and you will fall in love with it. It is a work of art.

O-rly? Hrm, any chance you still have his contact?
I also must point out that the lens was priced in dollars, and in May 2008 when I bought it the exchange rate was about 1.9500 , making it cheaper in sterling.

Hrm, really? I've only seen both the K and A going for obscene amounts on the bay. Where can one get one for cheaper then?

..... but you buy it anyway.
Actually £300 is a bit steep for the "K" version.
