I was a bit naughty - went into a photostore and picked up
a D70, fitted the Sigma 12-24 lens. When I got home and looked
at the pic, I was pretty disappointed by the quality, (very noisy)
until I looked at the exif data and realised I was shooting at
ASA 1600 - so it was forgiven. Little distortion even at the
ultrawide setting - will I buy it - watch this space.
