Much better Aiki - this time you have got the title right.
If I had taken the second one I'd be quite pleased with myself.

Hmm it seems base iso of the K7 & K20D is ISO100 indeed.
K-X is around ISO400
K10D makes no different ISO 100 or 200
What brings you to these conclusions Stefan?Hmm it seems base iso of the K7 & K20D is ISO100 indeed.
K-X is around ISO400
K10D makes no different ISO 100 or 200

I have seen a bit about this too. Up until now I had always shot at ISO 100 as far as possible, assuming that this would give the best quality pictures.
It seems that may not be the case. There seem to be two explanations, both of make some sense.
1/. The analogue part of the sensor will have an optimum signal to noise ratio.
2/. There will be a signal level which requires least processing by the camera, minimising errors and noise introduced by that processing.
People talk about a "native" setting for each sensor and for the K20, as Stefan says, ISO 200 seems to be the figure.
All this is quite simple to prove or disprove - all it takes is to take comparable pictures at ISO 100 and 200. Unfortunately with the grotty weather and the inertia I suffer from at this time of the year, I haven't got round to it.

Not to mention the Sigma EF530 DG ST they were allegedly selling at half price last May.

Thanks Tim. I went back to the original jpg so the colours may well haver changed. I'll have another go.

Is this any better?

If you really want criticism Aiki, you have mistyped the title.

I'd be tempted to crop some of the track in the foreground. Just a thought.

No problem at all Bob, other than you could have given the poor chap a scarf.

I had the same first thought as DM, but I cannot see how that would explain why that would effect one lens but not another. Very odd.
