Hi All,

I bought new Sigma 8mm F3.5 for my 5D and I started to take 360x180 panos in the end... Here is the my first 3 shots from London: http://www.fethiyeholidayvillas.co.uk/360.html

But I am having a big issue with sharpness; I never used really wide lens especially as fisheye... I need some advise to fix my sharpness issue for in&outdoor...
