I should have added that the Samyang/Rokinon lenses are available under many brands. Walimex is one such brand. Others are Bower, Opteka, Vivitar, Phoenix and Quantaray.
I think the main brands are Rokinon for the US market and Samyang for the rest of the world.
how good is fisheye lens on D3000 bodies. i thought be better to use on D5000 or D7000 series or D700 or D800 or 500 be way better. do to fact you can control the Fisheye better then D3300
