RE: OT: Fisheye for HDRI capture

[Nils Engler <soft.list(at)3ft.de>]

italian manufacturer agnos has a panohead or the 8mm fisheye that  
compensates for the crop of non-fullsize sensors by offsetting/  
rolling the camera. got myself one of these last year and am really  
happy with it.

for the complete setup you might want to have a look here:

cheers,
nils

ps
there´s also a new sigma 4.5mm circular fisheye for non-fullsize  
sensors.
