Welcome to Nikonians. You might want to complete your profile so better answers can be provided to any questions you have.
I'm going to assume you have a D70s. If so you have the DX format and that can change the "fisheye effect" of certain fisheye lenses. Nikon introduced the 10.5mm Fisheye especially to address that issue for a fisheye lens.
I'd generally avoid the "fisheye filter" lenses as they tend to be high on gimmick effect and low on quality. The Nikkor lens mentioned costs (I believe) around $500.00. The gimmick "fisheye filers" usually cost less than $100. for a reason.
