      I didn't get past all the advertising to actually download your file, but

      I would point out that you don't get the full sharpness of which a lens

      is capable by just looking at the RAW file. A little (sometimes a VERY

      little) judicious sharpening will show you what it is capable of. The

      Pentax 12 - 24mm rectilinear zoom and its Tokina twin have the reputation

      of being very sharp, and I can verify that, but only after giving it a

      bit of help. It may be the same for your Samyang. (You didn't way which

      lens but I assume it is the Samyang 8mm.)

        Absolutely don't trust the focus scales on any of their lenses! I found out the hard way with a 35mm that I rented, and see that both my 14mm and 8mm have the same issues. I used this link to find out how to fix it so that I can reliably use hyperfocal settings when shooting.

        I had found by myself the same way to mechanically set the focus scale ring at the correct position. I can confirm that it made me a happy user of the Samyang 14 mm for more than three years now. 
        I was inspired by Jeffrey R. Charles who had kindly taught us in 2009 how to solve the problem that similarly affects the Samyang 8 mm f3.5 fisheye lens. It is a simpler fix than for the rectilinear WA though:
