Thanks all. With the low light and the tight DOF it's tricky balancing framing and focus in this little clearing. I tend to spot focus on the eyes and reframe the shot, but with him moving at the same time I've got plenty of OOF pictures (esp. the eyes) than in focus ones.

Does anyone think using selective focus points on moving wildlife would work better instead of using the focus/reframe technique?

I've not played much with the selective focus thingy.

This was shot into a small gloomy clearing on a cloudy day. I've been trying to shoot this cock for some time, but when the sun is out it's very hard to get the right exposure and the pesky thing is very flighty.

C & C welcome - I know I clipped the tail and there's blur on the trailing foot, but he was actually a little too close to frame just right

Isn't noise cancellation where you take a black picture and subtract that from a long exposure to remove noise/interference at the sensor to give you a cleaner picture?

They look fine to me using DNG on the K20D - except you get a ~15% black bar to the right.

Incidentally, there's also a Tamron option (SP AF70-200mm F/2.8 LD (IF) Macro) coming for Pentax:

Will the new Pentax fit Sigma 120 - 400 have the motor fitted in the lens

Apparently, yes it will have a HSM (SDM) motor. But, it won't have a screw drive, so on older cameras it's MF only.

This is a list of Sigmas abbreviations:

Sigma call it OS for in-lens stabilisation.

They are both meant to use HSM on Pentax (so they will only AF on the K10D and K20D) - they won't provide OS, though, within the lens.
