looking for a good "square" fisheye lens d-Rebel.

[zacker]

is there such a thing? I would like to know if anyone here uses one or not and if its worth the money and where can i get one... also, whats the correct name? Im sure its not "square fisheye" that would be too simple wouldnt it? I just dont like the round ones, i mean, you try not to buy a zoom that vignetts and what happens, you wind up with a fisheye that vignetts like a mother......
thamks!

What you're looking for is a "full-frame" fisheye, and, unlike Nikon, Canon doesn't make one for the 1.6x crop sensor cameras. It would need to provide 180 deg. FoV on the diagonal; focal length would be somewhere around 9.5 mm. There are 8 mm fisheyes around which provide a circular image on a 24x36 mm sensor (or film), but on the DR, they almost fill the frame.

Extending what Jon said, there are good full-frame fisheye lenses in the 15-16mm range, and you get a good fisheye effect on the small sensor as well as a wide, sweeping view. I think the 16mm fisheye covers the scene equivalently to a 14mm rectilinear wide, though the comparison is inexact. In the 35mm format, we'd be talking about 24mm fisheyes covering about as well as a 21mm rectilinear wide.

The advantage of fisheye projection is that round things in the scene stay round and natural looking, even in the corners of the frame, instead of being stretched unnaturally as with a rectilinear wide. And subjects near the center of the frame are larger with respect to the field of view than with a rectilinear lens. You get both of those advantages from a 15 or 16mm fisheye even without getting 180-degree coverage across the diagonal of the frame.

The disadvantage is that straight lines that don't go through the center of the image will be curved. So, rectilinear projection is more faithful to straight lines, and fisheye projection is more faithful to curved shapes. This is true even without the full coverage.

Canon has a reportedly excellent 15mm full-frame fisheye, and so does Sigma. For much less than either, the Russian Zenitar 16mm/2.8 fisheye is a good performer even if you do have to use it as a stop-down, manual-focus lens (neither of which is much of an issue at this focal length).

It would be nice to have a 10mm fisheye that provided a full diagonal 180-degree coverage on the small sensor, but I have this feeling it would be available only from Canon and only in EF-S mount. That would not be much use for we 10D owners, and I suspect it would not make financial sense for Canon.

If you want a "square fisheye", I guess what you really want is a rectilinear ultra wide-angle lens. I think the widest prime Canon makes is the 14mm f/2.8L.

Zenitar 8mm on your rebel be like 16...woo nice and cheap too google kiev camera

The Zenitar woud be a decidedly "Round" fish eye.

OMG!! My eyes are tearing over this...:lol: i forgot i started this thread a few days ago.... i should have subscribed to it so i cold have at least acknowledged your responses... :oops: Whew!! Excuse me ...im just on info overload.. Thanks for all the info.. I saw (on here i think) someone got a new fisheye for the 350D or 300D... and took some amazing shots ..one of a church and a few other B&W shots...

There is no 8mm Zenitar. Russian fisheyes for small format are either the 8mm Peleng or the 16mm Zenitar. The Peleng is a curcular fisheye that will make a round image on a field of black on a full-frame 35mm image. The APS sensor cuts off the tops and sides of the circle, but the result is not a full-frame fisheye.

The Zenitar fisheye is 16mm and provides coverage of the full 35mm frame.

Beware of the descriptions on the Kiev Camera website. They sometimes report equivalent focal lengths instead of actual focal lengths. Thus, on some of their pages, the Peleng is reported as 12mm and the Zenitar as 24mm, but in fact they are 8 and 16. I've mentioned this to Mike but he apparently decided against making the change.

That was one of the other threads on fisheyes, and all those images were made with 15 or 16mm full-frame fisheyes either various formats (10D up to full frame).
