But it is heavy and requires a panohead with a long spherical arm.
As far as I remember the setting is around 135mm on the D700
And you need of course more than the 6+1 images which you need for a fisheye.

- They DO have quality check problems. The better the lens, the more complicated it is, the worst for QC... See the 12-24 fullframe, reported to be one of the most incredibly good ultrawides ever. One over 3 is not perfect. They are not lens to be bought 2nd hand.;-)2012/4/27 Roger D Williams <roger@...>From the experience of users in Japan, Sigma has an excellent record in admitting poor product performance and prompt replacement within the warranty period. If I was disappointed with the performance of a lens that others had found "outstanding" I would be back at the ship demanding a quality check and either adjustment or replacement. This might be harder for purchasers overseas... How would you pay for the to-ing and fro-ing of products that proved to be within spec?That said, they do appear to have a quality control problem. My own 8mm f/3.5 Sigma is on a par with the excellent 10.5mm Nikon fisheye.Roger W.
Sent from my iPadMy 15mm 2.8 is SO good it can be second only to 16mm Zeiss Contax. Many others here had quite different experiences...Il giorno 24 aprile 2012 07:32, Bostjan Burger <si_lander@...> ha scritto:At f22 the images would be too soft, especially with lenses like Sigma 8 mm.

Probably not. At f/22 diffraction will be large enough to prevent moiré...
