Which fisheye for this image type

[Peter Knight]

Hi 

For a full-fame camera (Canon), I can find fisheye lenses for image types 1 and 2.

Is there a particular lens which will give me the crop on image 3? 

IE 180 degrees top to bottom assuming camera is in vertical.

Thanks again

The Canon EF 8-15mm f/4 L lens will give all all three options on a full frame body.

It'll give you the barrel shape at about 12mm zoom.

Thanks JR. I suspected that after your last comment pointed me in that direction.

Seems like a beautiful but expensive lens. Might be well out of my budget :-/

Hello Peter,
Image 3 is just something in between 1 and 2. So if you buy a zoom lens
which can do 1 and 2, it will be capable of 3 as well. To be closer to
reality, say, Canon 8-15mm does "image 1" at 8 mm, "image 2" at 15mm,
and at a focal length of about 12mm it will do what you call "image 3".

You could consider the Tokina 10-17mm fisheye, which is very much cheaper.  See review by Michel Thoby at http://michel.thoby.free.fr/Tokina_10_17/Intricate_Panography.html .  Note that the later lenses were made optionally available without the sunshade so "shaving" is then not necessary to get maximum fov on full frame sensors.

In theory the Sigma 10mm fisheye should give you that type, but I have
no personal experience. Could also be you need to shave it for full
frame. Does anyone know more?

According to the PTGui lens database the crop circle for this lens is a
bit smaller. Somewhere in between your type 1 and 3. Sorry.

That's a good find. Thanks John.

I read a review of the Tonika that mentioned the edges could be excessively soft. 

I can't find the actual link now but I wonder if it was an early edition with either earlier hardware or earlier firmware.

Does anyone here have one and what's your thoughts?

Cheers

Make a search on Google, and maybe in DDReview.com ! You will find a lot of posts about the Tokina 10-17, and some comparisons with the other (at the time) mostly used fisheye, the Nikon 10.5 f/2.8 (mostly used with the sunshade cut off, so it could be used on full frames cameras) !
