For my Nikon, for a decent one your talking about Ģ350-Ģ450, I think the pound is worth more than the euro too so even dearer. Is it a true fish eye though, as in 180 degree viewing angle. I ask because the picture doesn't seem to show that unless it is cropped, if it isn't cropped you should really see your feet . True fish eyes are VERY expensive usually if you want a good quality one.
no itīs a real fisheye lens with 180 degree viewing angle you can read about it here [link] depens very much on the angle youīre holding vour camera if you can see your feet, more often you have the tripod on the picture.
