The problem with the Sigma SD1

Extensive review of the Sigma DS1 Merril at Dpreview :-

Pretty much as expected.

However I looked very closely at the samples and you get this.
From the centre of one of the samples. Impressive.

Then I looked at the two edges from the same picture.

Not so impressive. In fact not very good at all. Taken on a Sigma 17-50mm f/2.8 zoom at f/8. Unfortunately it seems Sigma are having a good go at sabotaging their brilliant (if somewhat limited) sensor with the lenses they produce for it.

Having spent the afternoon with my X-Pro 1 and a couple of Voigtlander m-mounts, I can report that there are no such problems with lenses and an image quality thats about the same from straight out of the camera jpgs.

I'm putting together samples and a post for tomorrow on that. But just to wet your appetite, the most fun I've had for ages with a camera in my hand, and the pictures were pretty good too!!
