Regarding Fish Eyes - Is there some type of rating which tells you how much viewable area you can have? For fun I purchased some generica fisheye off of ebay for $50. (Bower Titanium .42x AF Lense However it would take 6+ shots to do the entire area. Obviously I would need something bigger thanks!

Look for the Angle of View. For the Sigma or Canon 15mm Fisheyes, both list an Angle of View of 180degrees. Which basically means it takes in everything forward of the shooter.

However, remember the crop factor! Unless you are shooting with a 1Ds, the crop factor will remove the edge of the picture, so no fisheye will ever show you "the entire area" on a 10D/300D/1D mkII.

Any lenses you would reccomend? The always do seem quite expensive...

I went to Canons lense site and did not see anything on fisheyes..

http://consumer.usa.canon.com/ir/con...categoryid=111

Do you have any URLS? How do they compare to Nikons fisheye. They seem to be the one that IPIX likes.

Thanks

I do not have a fisheye lens, although I do plan on including it at one point.

What camera do you have? In terms of fisheyes for the EOS mount Canons, you only have a few choices. Canon or Sigma for auto focus. Zenitar (Russian brand -- cheaper) for manual focus. Not sure why you'd want to compare them to a Nikon lens, if you own a Canon mount camera.

FYI anything around 15mm or less is considered a fisheye: http://consumer.usa.canon.com/ir/con...categoryid=151

The only thing comparable to the Nikon ultrawide zoom is this Sigma: http://www.sigmaphoto.com/Html/news/cm_gr_prx_04.htm

It's an apple and orange comparison especially when one is a prime and costs twice the other which is a zoom! :idea:

Please reconsider this statement. What makes a lens a 'fisheye' is the distortion left in the designmaking the image curve in at the edges. Lenses like the 14 and 12-24 are corrected to be rectilinear (=not fisheye) while the 15's (and cheap Russian 16's) are 'fisheyed' so they include more angle of view than a corrected lens with a shorter focal length.

Compare rectilinear:

and

fisheye (curvilinear)

dougsmit is quite correct.

There are also 2 types of fisheye lenses. Those that give you a circular photo, and then there are those that will give you a full frame photo.

Lenses such as the Peleng 8mm fisheye, are at the extreme end, and give you a nice round image, and thus fall into the first category.

The Zenitar 16mm is considered a full frame fisheye, as it does not give you the feeling that your looking through a port hole.

The following link should give you enough information about these Russian lenses. Personally, I have never owned one, but I am tempted one of these days, to pick up a Zenitar to mess around with.
