Um Cleetus, what does this have to do with a mac?
Being uber lazy id recomend the Nikon Capture software (it came with my camera free), and just clicking "defish" or download the panotools plugins for photoshop.
Man I want a 10.5 so bad!
Have fun
Dylan

Sorry for the poor explanation triggerhappy, there is a software named "defish" for macs I wanted a similar program for PC. I will try the plugin.... I hope it has a tutorial. My brain has been a little slow lately I have been learning so much that some of the little things can stump me. I just got a D100, 10.5 and a 360 precision... Once I learn to take a little better pictures I hope to have some great east coast panos up to share.

PTLens plugin help is in the PTLensPlugInHelp.pdf file included in the plugin zip.
The main advantage of using PTLens plugin to defish a fisheye image (besides the fact that it includes vignetting and chromatic aberrations corrections) is that you can adjust the amount of defishing. I often use "intermediate defishing" (resulting image is not a "full-rectilinear" one) because I prefer such result. (Your mileage may vary!)
Following an inescapable math law, full circular 180° (or larger than 180°) fisheye image can't give a "fully defished" rectilinear image: if you try to do that using PTLens, what you get is a grey pixel surrounded by many black ones: this is not a program fault but a decent approximation of the infinite resulting image this would make!
You can use other Panotools front-ends (Hugin, PTAssembler, PTgui) to defish + adjust the prespective. I use PTAssembler for that: moving the PTA "Reference Point" to the left or the right and/or up and down results in various perspective corrections: just select the one you prefer.
What I often do is to make a 360°x180° equirectangular version of full-framme fisheye images (where full-frame means diagonal = 180°). Though a large part of the result is black, I can navigate this result using a viewer: I believe the best viewer for that is FieldOfVision SPi-V because one can just drag the JPEG onto its icon and wait a few seconds before getting the view (no cube is needed).
Another interesting viewer is Mind-Eyes-Viewer (it can be found on the Pictosphere site). Using it, you can make plane projection of an entire sphere (I don't know the name of such a projection, perhaps it's hyperbolic?), or (using its "Picto" button) view a spherical version you can rotate using the mouse! Here is a post about that on Max Lyons website: www.tawbaware.com/forum2/viewtopic.php?t=2756
Fisheye + projection tools + perspective tools = another photographic world to explore (...but you should not hope many applauses when showing your images.)

Hi Cleetus,
I just got a 10.5 and was faced with the same problem. I have PTGui but the 10.5 is not part of the lenses that are calibrated and I am not good enough to work out how to do it by entering data myself. I am using DxO and it works a treat! Defish in DxO and stich in Sticher, no worries...
Cheers,
Gerard

Hiya Snail, I have been testing this lens with a variety of software, with PTgui just select the fullframe option and click ok! The program can stitch them fine without defishing automatically.
Have fun
Dylan
