Hello, What is the difference between a wide lens and a fisheye lens? I am looking at these lenses

Tokina 12-24mm f4 AT-X 124 AF Pro DX II
Sigma 10-20mm f3.5 EX DC HSM
Sigma 10-20mm f4-5.6 EX DC HSM
Sigma 10mm F2.8 EX DC Fisheye HSM
Nikkor 10.5mm f2.8G ED DX Fisheye AF-S
Nikkor 10-24mm f3.5-4.5g ED AF-S
Nikkor 12-24mm f4g ED-IF DX AF-S
Tamron 11-18mm f4.5-56 Di II
Tamron 10-24mm f3.5-4.5 Di II

Thanks :)
 
Wide is just wide, (will curve the image slightly at the edges wide sometimes)

Fisheye, Diagonal ones are designed to curve the image substancially, a 360 degree one really curves everything up and is a round image with vignetted corners.

a very brief and basic explanation before someone babbles on about it needing to be more indepth.
 
Thanks fastworldimages that was exactly what I needed to know. I now know its defiantly the wide lens I require :)
 
A fisheye lens usually produces a circular distortion in the image and produce a near 180 degree perspective/or field of view, those would be the main differences. Wide angle technically means anything between 10(ish)mm and 28mm.
 
Basically fisheye lenses fall into two categories, full-frame and circular. The full-frame will offer approximately 180 degree angle of view and fill the entire frame, however there will be substantial distortion particularly near the edges of the frame. The circular fisheye produces just that - a circular image.
 
Just an aside, when going for a wide zoom, don't just go for the widest lens; two of the lenses you've noted, the NAF 12024 and the Tokina 12-24 are probably two of the best wide lenses around regardless of price. You've also missed off a cracker, the Tokina 11-16mm f/2.8. I'd get any of these three before I even attempted to think about the Sigma 10-20mm - too many bad example floating around; the NAF and Tokina ones are pretty much the benchmark I think. Sigma do a 12-24mm also, which is designed for full frame and 35mm use but it's very, very good, as is the 15-30mm they do - now that's a right good buy.

The NAF 10.5mm is a great little lens, very well built and probably one of my next purchases, but it's very limited because of the fisheye effect. Same applies to the Siggy.
 
ill be getting a Tokina 11-16mm f/2.8

at some point

dont know when yet, but really want one of these
 
Sadly I require a built in AF drive motor so that severely limits me. I cant really afford a Nikon lens thought I have got my eyes out for a cheap used one.

Click to expand...

A true fish-eye has 180 degrees angle of view and is uncorrected for rectinlinear distortion - straight lines at the edges of the frame curve outwards.

A wide-angle, even a super-wide will not get near to 180 degrees and is rectilinear - straight lines at the edges are straight. Or at least they should be - some wide-angles still have a bit of barrel distortion but it's easily corrected in post processing.
