Hi Dallas, thanks for the article. I was interested to see you used the Samyang 7.5 then straightened it in LR. The results look OK on the low res shot you posted. Are you happy with the result as a high-res image?
The reason I ask is I've been thinking of getting an ultra-wide angle, but the idea of a fisheye intrigues. The cost of rectilinear UW is high (eg, even the Laowa manual lens is pricy, given that it's not a widely recognised brand).
I'm curious to hear what you think of your Samyang, especially used in this way.
