Canon D60 10D + Sigma 8 mm Review/Test - Digital Camera + Fish Eye (8mm Fisheye) for, Panorama, Panoramiques
I had made a lot of research before buying this Lens and I already had been using the Sigma 15-30 mm Zoom for a couple of weeks before I got the Fisheye..
I have been using negative film with my Pentax Full Frame fisheye for 2 years for my panoramas and I was very curious if the D60 and the Sigma could give me the same quality..

The 16 mm lens exists in four versions, with some substantial differences between them (only the differences between 3rd and 4th version are mere cosmetic): MC Fish-eye Rokkor-OK 16 mm f/2.8: Construction: 11 elements in 8 groups Min.
All manual-focus Minolta fish-eye lenses are discontinued from production.

Before Minolta produced the MC 16mm full-frame fisheye, it had the 18mm f/9.5 MC UW Rokkor-PG.

FishEye Menu in Winforms - The Code Project - Menus & Toolbars
Download Demo - 12.0 KB Download Source Code - 36.5 KB Introduction This is my first article, in which I try to present a basic way to make a fish eye menu control, in which the item the mouse is over is enlarged, and the surrounding items increase an decrease their size when you move the mouse.
I wanted to know how hard it would be to implement something like the fish eye menu, and although the code is very basic, it serves as a starting point for improving and making it better.
You could increase the fish-eye effect by (taking a guess here as I haven't looked at your code) using a delay to resize the elements {SelectedItem} - 1, -2 and {SelectedItem} +1, +2 right now they instantly change size and you don't get the feel of motion/transition.
My only suggestion would be to not be afraid to make the text outside the fisheye a little smaller.
It'd by nice to illustrate your description of the paint algorithm with some code and maybe use some XML to define the font, size, and color for the different fish-eye levels..

I'm not sure how to explain it, but if you move your mouse real slow from up or down you will certainly find mouse positions where the fisheye effect disappears completely.

Imagealign-15mm
When I was a teenager in the 1960's the hottest new lens was the "fisheye".
Though they had been available for at least two decades prior ( used primarily for scientific / meteorological applications ), it was Nikon's 8mm f/8 fisheye lens of 1962 for the Nikon F that really started the excitement.
Other manufacturers quickly followed, prices dropped, and it wasn't long before Spiratone had a screw-in accessory adoptor that produced a fisheye look for under $100..
But the appeal (or at least the uniqueness) of circular fisheye photographs soon waned, and though they're still around today they aren't seen very often.
There is a third alternative though — the 15mm or 16mm full-frame fisheye .
Like the circular fisheye lens its coverage is 180 degrees, but instead of producing a circular image with 180 degree coverage in every direction it produces a full-frame image with 180 coverage on the diagonal.
Sigma's 15mm F2.8 EX Diagonal Fisheye is less costly at about $350..
Even a 14mm lens sometimes isn't wide enough, and when including a broad area is more important than accurate and linear perspective a rectangular fisheye can be just the ticket..
