I’ve never experienced my fisheye creating special effects. It’s a very wide angle view, if you wanna call that “special fx”, but it’s really a quite natural view, given that its job is to deliver a 2D representation of a 4D world.
Not all fisheyes work their magic the same way on the same scene. The FE image is closest what our vision sees if we learn to minimize the intrusive knowledge of our brain. We don’t really see a world full of straight line architecture, horizons, sidewalks, etc etc. Our non visual experiences inform us that these things usually follow the principle of “shortest distance between any two points” and our minds impose that nonvisual info on what we see.
Most “photographers” take Renaissance perspective at face value as being accurate but it’s really a flawed crutch, as likewise any method of representing the world in 2D form is always flawed. A “rectilinear wide angle lens” attempts to mimic Renaissance perspective, complete with the innate flaws.

I would say that lens has very limited use. I have a Tamron 10-24 on a 1.6 crop camera and that's plenty wide

I bought a used one and found out it won't focus to infinity, so I never use it.

I just wish the barrow effect could be solved.
That “barrow effect” is why it’s called a fisheye. For a crop sensor camera I think 10mm is about as wide as you can get without the fisheye effect. Full frame I think it’s 14mm.

My reference to a fisheye lens as a special effects lens was a poor choice of words. However based on this thread, and an earlier one by the OP, what he clearly wanted was a wide-angle rectilinear lens not a fisheye. In this thread and in his previous one he seems intent on finding a technique to make his fisheye images look rectilinear.
While a fisheye is capable of very interesting images, I've never been interested in owning one myself since I would use it too infrequently. Photography is an artificial medium which captues a moment in time In only two dimensions. Our eye-brain perception allows us to accept a lot of images as natural looking which are actually far from it. However the results from fisheye lenses generally don't appeal to me even though I have occasionally seen some spectacular ones.

Thanks. Very well put.
I was also unaware of his earlier thread flogging the same mule.

...one of my fave lenses is a 10-17 Tokina DX. I use it infrequently (along with my Sigma 15mm FF Fisheye) but when I bring it out I have a great time. I'm not a purest, obviously, and love the artsy look...the *real* fun is setting up shots knowing what the outcome will be. AFA the OP wanting to *not* deal with the effect, well, I give that a big <shrug> but there are plenty of tools in PS (and even LR) that will "straighten" an image, but you inevitably lose some content.

I've had an older Samyang 8mm but sold it because the nonremovable lens hood showed in full frame images. I now have an Opteka 6.5mm which is probably the same as an 8mm lens. It is a truly fun lens!
I primarily use the fisheye for full sky imaging, in particular Auroras. It has some value for landscape imaging but the distortion is hard to deal with.

I have a Rokinon 8mm circular fisheye. It's cool, but a bit of a novelty. Keep the camera level and at least the horizon will be straight. Pointed straight to the sky amongst a stand of white barked aspens, can be way cool! I'm about to upload a full moon timelapse, but will come back here and post some images.
On my crop sensor 7D II, the focal length is 12.8mm, so not quite so dramatic, and the lens hood can be used, fwiw.

For me it is almost always my feet that get included in the image. I need to remember to lean forward a bit to prevent it.
I've had some of those too

Yes, the Rokinon version.
Love it.

Nice shot! But you either cropped it or shot it with a crop sensor camera. And kept it dead level.

7D, No purposeful cropping.
Used PSE to straighten the curves a bit but could not get rid of them completely and some parts got "Cropped" by virtue of the straightening. The corners only as you can see.
Here is the SOC from the Raw.

I look forward to seeing those post.
All images with a Rokinon 8mm f/3.5 HD Canon EF mount.
The first image is paired with a crop sensor 7D II. 12.8mm effective focal length. Rectilinear image but extreme fisheye effect. The others are all with a 5D III, lens hood off, but the image isn't fully circular.
The 3rd image is underneath the Lake Quinault western redcedar, 6/5/2016. Looking straight up. It was the largest tree in the world outside of California by wood volume. It failed, not 45 days after I was underneath it doing my thing!!
