We’re trying the new Rikinon 8mm Fish-eye on architecture. North Park Boat House has been an object of wide angle experimentation several times this year. Here’s the same image, but corrected via PTLens (left). I have the relevant sliders pegged to maximum, and still some distortion remains, but it’s pretty close. For comparison, the second image (right) was taken with a Tokina 11-16mm Wide Angle, shown uncorrected and corrected with PT lens.
