Q: 5. Looking for a wide angle to use when shooting my A7S II when shooting at 120 fps (which crops the sensor at 2.2) So the focal length would be about 25 mm? Will this remove most the fisheye bending?

A: This lens should create, on a full frame camera, a circular 180 view. When you go to 120FPS, the fisheye distortion will be unchanged for all that happens is that image is cropped and you are left with what is in the center.

Q: 6. I am confused. How do you manually focus a pinhole which by its very nature is always in focus?

Q: 7. Is the Twist 60 at all effective with a crop sensor camera, like the micro four thirds format?

A: The Twist 60 was designed for full-frame cameras. We don't recommend using it on a crop sensor camera because a lot of the twisty effect will be cropped out by your camera. Here is our Twist 60 comparison between a full-frame camera and a crop censor camera: a href= http://lensbaby.com/twist-60-full-frame-vs-crop-sensor/. target= _blank http://lensbaby.com/twist-60-full-frame-vs-crop-sensor/./a Here is a review of this optic on a crop sensor camera: a href= https://www.lifepixel.com/gear/lensbaby-twist-60. target= _blank https://www.lifepixel.com/gear/lensbaby-twist-60./a There would be even more of a crop when using a Micro 4/3 camera.

Q: 9. Is it rectilinear corrected?
