15 mm fisheye vs. 17 mm from 17-40 L

P@ · Jul 19, 2004

Like some of us I am looking for more wide angle an a 10D.
How much do I win buying the Canon 15mm 2.8 fisheye ?
I allready own the 17-40 L.
I think is more than 2 mm, but I like to know more before buying (or not).
A link to another thread is also nice.

Thanks

It's more like 5 mm. The field of view on the Sigma 15/2.8 dia-fish de-fished is very close to the FOV on the Sigma 12-24 at 12 mm -- a bit more horizontally, a bit less vertically, and just a hair less diagonally.

Incidentally, most people would probably recommend the Sigma 15/2.8 over the Canon one: they're optically very similar, but the Sigma is much less expensive.

If possible, could someone post an image of a 15mm fisheye on a 1.3x or 1.6x crop DSLR? I've been wanting a fisheye for a while, but have been hesitant to get one due to the crop on current prosumer DSLR's. How different is the image from a full frame camera as I know that most of the distortion of the fisheye is towards the edges...

Here's one of my favorites:

Taken with the D60 and a Sigma 15 f2.8 fisheye

And here's the rest of them:

None of them have been cropped or defished.

If you go here:

http://66.180.118.166/misc/HighFive/

and check out the 2nd and 3rd images, the 2nd one is the 17-40 and the 3rd one is the 15mm fisheye. If you click on the images there are links to full size unedited images.

Don't look at the full size images TOO much for sharpness, because these were long exposures on a vibrating bridge. They should give you a good idea of the difference in FOV between the 17mm lens and 15mm fisheye on a 1.6x crop though.

Thanks Angela.
What camera are these shots taken with? (i.e. what crop factor)

Here are comparisons between the Sigma 15mm f/2.8 fisheye and the Canon 20mm f/2.8. The harpsichord and the Concorde are from the Canon f/2.8.

I personally prefer the Sigma 15mm FE. I find it a very useful and fun lens.

Sorry, just saw on your webpage it's a D60.

Thanks for the photos everyone. They're a good indication of what a fisheye looks like on a 1.6 crop.

Though does anyone have any on a 1.3x crop? I'm after a 1.3x crop on the DLSR I'll get at the end of the year (probably a 2nd hand 1D, or if it's released with a 1.3 crop, a 10D successor) and wouldn't mind seeing hte difference.

Thanks

Here's a 1D straight out of the camera with the 15mm fisheye. Good contrast to it:

8, 16 and 20mm on a 10d
http://www.pbase.com/denisb/fish_test
8 and 16 are fisheye, 20mm are rectiline.
8 mm was taked at ± 1 meter of the bike
16mm was taked at ± 2 meter of the bike
20mm was taked at ± 3.5 meter of the bike

example using the 17-40 vs a Sigma 8mm on a 1D (1.3 FOV). The first is the 17-40 @ 17.., the second is the 8mm and the third is the 8mm defished with Panotools and the overhead powerline cloned out.

woundn't this lens be better than a fisheye? (for landscape and city shots)

dgolchert · Jul 19, 2004

Perfect. The 1.3 seems to show the curvature more than the 1.6 crop of the 15mm lens. Migth buy one of these after all.

Are those hot pixels? 2 on trim at upper right, 1 on back of sofa in front of the cameraman, 1 on ceiling on upper left. Do they show up only on long exposure?

It's like getting 2 lenses in one.

On 10 D you can control the FE distortion by composing the image. Or you can defish afterwards. I had it for over a month and still hasn't gotten any defish software.

Here are some samples...

This one was taken by the guy on the left in the green shirt.

Here I just leaned back in the chair

Self explanatory...

The 1D is one of the worst hot pixel cameras of all time. I'm sure they are hot pixels that would go away at shorter exposures. That's nearly 1 second on the 1D, that's not too bad!

Canon 17-40 vs Canon 15mm vs Zenitar 16mm.
I have all 3 lenses and did a simple test to see which is widest:
