Title: a little fisheye... a little photoshop
Post by: Frank in JC on March 31, 2008, 01:00:39 PM
I've been playing around with the Nikon 10.5mm fisheye for about a week and it's a blast!  This is one of those touristy binocular things from a couple inches away, de-fished into a rectilinear image with software.

The focus knob actually reads, "Turn to clear vision," but it seemed to be begging for this.

Very cool.... I've been thinking of picking up the fisheye for awhile, just can't afford the nikon one for how much I'd use it.

Really nice stuff.  Makes me want to break out my 10-20 and play around.

I wasn't sure what the heck I was going to do with it, but I'm crazy about the surreal images created by ultra wide angle lenses.  When de-fished, the corners get soft, but it's still ridiculously wide, waaaay wider than the 12-24 DX!  It's also tiny, so it's no hassle to bring along.  The problem is that the effect becomes monotonous when overused.

Another fisheye, this one uncorrected.

I was working in downtown Manhattan yesterday and saw this fire company across the street.  Engine 6 was one of the first responders on 9/11 and they lost four firefighters.  You've probably seen images of their truck which was crushed by the collapse and partially burned.  The station's exterior has since been renovated to look like this.  I'd say that's a lot more than just red paint.

Mmmmm....fisheye. Love 'em. I have a 15mm full-frame Sigma fisheye that I use frequently.

I absolutely love the first shot. Very nicely done. What camera did you shoot that with? If digital, what's the crop factor? (just curious)

It's with a Nikon D300 which has a 1.5x crop and the lens is designed for that sensor size.  As a result, unlike full-frame fisheyes, this lens is really small and easy to carry around.  The first picture was "de-fished" which turns it into a rectilinear image at the expense of a sigificant part of the field of view.  The fisheyes seem to be the only way to get "crazy wide" with a cropped sensor, unfortunately.

I also had an old Sigma fisheye, a 16mm AI, but it literally fell apart despite being an all-metal 1970-early 80's model that was built like a tank.  The front element looked like a round glass ball, which was pretty neat.

Reminds me of my Russian Zenitar 16mm (Nikon mount):

The going rate for these on Ebay is around $150, depending on mount.

I haven't played around with it since I moved over to DSLR, but according to Ken Rockwell, the effect is only worthwhile on full-frame cameras:
