I am considering the Samyang 14mm Ultra Wide-Angle f/2.8 IF ED UMC but I am somewhat concerned about the 5.3% of mustache-style distortion this lens produces.
I like most of what I read about this lens and the primary purpose would be landscape nature/night photography but I also do some architectural photography.
"The biggest weakness of the Samyang is the rather extreme amount of complex barrel distortion (mustache style) which is difficult to correct during post-processing. If you're into architecture photography this will produce headaches." Source: Photozone
I am familiar with correcting barrel and pincushion distortion in post processing but how difficult is it to correct this type of distortion? I would also like to see an example of a mustache-style distortion in an architectural photo. I would appreciate is someone could post one or provide a link.
