cbass · 14th of February 2008 (Thu)

Post 'em up guys, I wanna see pics taken with a Sigma 15mm diagonal fisheye.

***EDITED FOR CLARITY***
Because this thread is for the lens archive, please only post pics from the Sigma 15mm Fisheye lens.

ask and ye shall receive. 1D Mark II with a Sigma 15mm Fisheye, of my cluttered work space.

Nice, thanks Justin!

Say, would you mind putting it on your 350D and taking the same shot?

here you go. a bit of a difference as you can see:

thank you, that's a great comparison. Any others out there with Sigma 15mm fisheye pics??

Probably not worth using on a crop camera. Same problem with my 16mm Zenitar -- nice with 35mm film but just not very fishy on an XTi.

If you're looking for a diagonal fisheye on a crop camera, there really are only two choices, and both are pretty good:

Tokina 10-17 fisheye zoom. Excellent image quality, excellent build, and being able to zoom a fisheye can come in mighty handy. While it's a true 180 degree fisheye at 10mm on a crop camera, it keeps that 180 degree fisheye status for all other formats too...it's got full coverage and full width at 12.5mm for 1.3x users, and it works just great on full frame between 15 and 17mm. (I have taken shots with it on my film body at 15mm, and they look fantastic.)

Here are two recent shots at 10mm with mine (both on my 30D):

The other option is the Sigma 10mm f/2.8 fisheye. It's newer, so there's less people who have used it but it looks good as well.

What's the big diff between diagonal and the circular and don't say one's diagonal and the other's circular.

tiktaalik · 17th of February 2008 (Sun)

A circular fisheye creates a circular image within the frame and gives you a 180 degree field of view in all directions. The diagonal one fills the image frame and gives you 180 degrees FOV only along the diagonal.

The outer image is the view from a circular fisheye. The view labeled 10mm is the view from the diagonal fisheye for crop cameras.

(And yeah, I'm way behind in posting images from my Sigma 10mm. Hopefully tomorrow.)

Jman13 · 17th of February 2008 (Sun)

Diagonal fisheyes are 180 degrees from corner to corner, and they fill the frame...there's no black edges. Circular fisheyes create a circle in the center of the frame, surrounded by black, and are 180 degrees all around.

In my view, diagonal fisheyes are pretty versatile if you know what you're doing. Circular fisheyes are pretty specialized.

_aravena · 17th of February 2008 (Sun)

Ah! So Tokina's 10-17 is? Some pics I've seen don't seem to have those blacked out areas.

tiktaalik · 17th of February 2008 (Sun)

You only get the blacked out areas on circular fisheyes (4.5mm and 8mm). You won't get that with the Tokina (on a crop body) or the Sigma 10mm.

_aravena · 17th of February 2008 (Sun)

Ah ok. Makes my interest in the Tokina more hyped.

Jman13 · 17th of February 2008 (Sun)

The Tokina is truly an excellent lens. I really, really like mine. As you can see from the shots I posted above, it performs quite well.

Gotta have full frame to really have fun with the 15mm fisheyes...
