A while back some scum pinched my old manual Sigma 8mm fisheye snd i missed the fun aspect of it so thought i'd try the new Sigma rectilinear zoom out.
tried it out on a range of subject and conditions at 8mm
Its image quality is sooooo far ahead of the old thing that they ar just not comparable.
the old one had a wider angle of view but nearly half the image was vignetted and the bit that wasn't was pretty fuzzy.
it was a fun lens ... but that was about it.
The new one is as sharp as the Pentax 12-24 but not that much wider view as i thought i would get ... any way, some images of its first outing:

1st...


distortion is pretty damn good...


and its wiiiide ...


good for interiors even if its only an F4 lens .. handheld ...


into the sun...


dark staircase and bright window...


all the pics have a bit of shadows/highlights and a light sharpen

did some landscape shots ...




a vertical shot 1 metre away from the girder with cars going over the storey bridge ...


some night shots resting on a rail ...




MY CONCLUSION: 8)
