Originally posted by Grippy Why defish? No point having the fisheye if you want to defish I reckon. Embrace it and learn to work with it, if it doesn't suit your shooting style, sell it and move on. Mine, I love it, it barely leaves my camera.
Why not defish? No point having a defish feature in lightroom, DxO and other and never use it!
I only defished here to illutrate the things of what possible as I used the DA15 that day for rectilinear shots, but not everybody has a DA15 + a DA10-17...
Not to say you should buy a fish to defish, but for the case of bertwert, he can get it for 180$, CAD I think. At that price there normaly no possible way to get any kind of UWA. A DA15 is $300 used and a 8-16 even more than that maybre 450$. The 10-17 also quite small (yeah the DA15 too) and a zoom.
So even for defished pictures, that's a better offering, because there no competition. Plus you don't have to defish all the time, plus defished picture will still offer a wider angle of view than most rectilinear UWA.
While people with the money for it and wanting rectilinear perspective rendering should avoid fisheyes, as long as you don't ask for the lens more than it can provide, you can get lot of things done with it.
There also many cases where you may want something in between, not full fish rendering, not fully defished and that 10-17 excel at it with its zoom feature. This zoom is one of the Pentax unique lenses and an interresting compromize.
