Two of us are discussing this piece of software for ultra wide angle lenses, including 8mm.
If there is anyone else who has used this software, we'd appreciate hearing from you.

If you have the latest versions of Photoshop and Lightroom, you already have the capability to convert semi-fisheye images to rectilinear images.

Having paid for PS since 2002, right up to PSCS6, I'm not using Affinity. Any ideas there?

Can't help you with Affinity. Sorry.

I have it, use it and find it very valuable (I use it on full frame fisheye, not full circle fisheye). It does not convert images to rectilinear, but makes verticals straight. Horizontal lines remain bowed. In that way the image looks much less distorted, but the image does not lose much angle of view, as it would if converted to rectilinear as with PS.

I'm clearly a student here. Full Frame Fisheye, and not Circular Fisheye? I thought all fisheye would be circular. Tell me more please, and tell me the difference. Example, is your Fisheye 8mm?

A full-frame fisheye does not have any black areas. The diagonal is 180 degrees, just at the edge of the image circle. For full frame, this is usually 15-16mm, depending on the type of projection (there are different types of fisheye projections). A "full circle“ fisheye gets the entire circular image circle into the frame, with the rest of the frame black. These are, generally speaking, 8mm.
For crop frame, full frame fisheyes are 7-10.5mm, depending on the projection. The only full circle fisheye I know of is the 4.5mm Sigma.
Fisheye projection types are equidistant, stereographic or orthographic, usually, with most all classic fisheyes being equidistant. Recently some near-stereographic fisheyes have been made (like the Samyang), and Nikon once made an orthographic fisheye. All cover 180 degrees, but they have different ways of achieving it. For stereographic, the size of objects in the center is smallest, with less squeezing of objects at the periphery. Orthographic has the most squeezed periphery, and equidistant is in the middle.

Where did you learn all of this? Next question, what specific lens are you using, for which it is a 'full frame fisheye', and not a 'full circle fisheye'? I don't know if this tells you anything, but I recently bought a Sigma 8mm Fisheye. Now that I'm learning that there are more forms of fisheye, I'm suspecting mine is full circle fisheye?

Altho I never had proper names for the differences, I’m probably the rare user who has actually noted such differences ... becuz I LIKE fisheyes, and so I have several. Seems most other users never have more than one (which they regret buying and never use).
TT Artisans 11/2.8 struck me as rather different before I ordered it, and proved to be different even in the first few test shots. 11mm is right between 8 and 15, yet it’s corner to corner on FF.
It’s really affordable but is kinda bulky compared to my typical 15 and 16mm, but the “distortion” is of a different type than most other fish. I recommend it to anyone who’s become “fisheye curious” on a budget. Or someone who is/was a fisheye user but has changed systems and not yet replaced their fish.

I am so impressed with your passion for fisheye. I have a question and a comment. First the comment: I just spent $790 on a Sigma 8mm fisheye, and as a retired teacher, that emptied my pocket very nicely. So a second fisheye can't be in my future anytime soon. Now my question: AS a teacher, I enjoy still teaching (part time college teacher here), and I enjoy learning more. I think Fisheye has opened a unique and fun door for me. It sounds like it has done the same thing for you. Can you and I continue to exchange email directly, rather than going through UHH? To show my earnest here is my personal email address: williamelliott937@gmail.com

By the title, I thought I was going to see a creative picture of a well known car engine! 😉

You made me smile about the play on Hemi engines. My 'name' has been played on as "Elliott", as in the race car driver. One of my students gave me a bumper sticker with: bill elliott: race car driver. Now I only have to put it on my rear bumper.
