A few from today... getting used to the replacement Bigma (the AF packed up on the first one, a few weeks after I got it). More practice required, clearly, but I think I'll make friends with it yet.

And another one...




The trick is to have the exposure long enough to get some prop blur, while not ending up with camera shake.

Subjectively, the OS in the lens seems a little better than the SR in the body for these. Not enough of a sample to be sure yet though.

Whilst I am no expert I reckon that you are getting the mix of prop blur/ shutter speed correct
K10D, K5 plus plenty of clueless enthusiasm.

I was thinking of getting a bigma for my K7,are they prone to packing up?
also the pictures looks a bit soft,do you use a tripod?

I had the AF pack up on mine, shortly after buying it. It was replaced under warranty, and the replacement has been fine.

Prone? I don't know if it's any more prone to failure than anything else.

If they're soft, I'd say it's my technique, rather than anything else that's at fault.

But a tripod? For fast moving aircraft? Erm, no. Unless the aircraft path is extremely predictable, a tripod is impractical for most aircraft shots.

The main thing that makes it difficult is that unlike jets, with propeller-driven aeroplanes, you have to keep the shutter speed slow, since with exposures much shorter than 1/200s, you freeze the prop which looks rubbish.

Inevitably, hand-held shots with long lenses and long exposures will tend to suffer a bit from shake.
