Re: foveon sensor and high iso

Here's the comparison pic's.

Please keep in mind that they were taken in very difficult lighting conditions, and with the exception of this first Pentax image they were all converted straight from RAW into a JPG and either re-sized or cropped.

Pentax ISO800

It was under-exposed, so I had to lighten it a little.

Here's the 100% crop.

Like I said they were shot using a Pentax K100D, on a tripod, with a Zeiss 200mm f2.8 lens. It's a screwmount, so the ISO isn't showing, but I believe that it would have been f2.8.

And here's the ISO 800 SD14 images, taken freehand, with my 24 - 70 f2.8 lens.

It was upsized in SPP 2.5, then re-sized or cropped using the same software as I used with the Pentax pic's. (ACDSEE Pro)

The 100% crop

ISO 1600 Pentax pic's

Sigma ISO1600

100% crop

At least in my opinion they really didn't turn out too bad, for un-processed images.

A friend of mine shooting the same event with a Nikon D300, and their 70 - 200 f2.8 ended up deleting all his images, saying that they were un-useable.
