A: Yes, the two have the same optics.

Q: 7. Does this lens change length when focusing or is it internal focus?

Q: 8. I have a Pentax K-1ii and when I mount the Samyang 135mm, the F-stop display on the view screen just flashes repeatedly; it shows "F --". I have changed the F-stop on the lens to try different settings, but the F on the display still flashes repeatedly. Is there a setting I need to change somewhere?

A: This is normal. The Samyang 135mm f/2.0 ED UMC lens for Pentax K-mount does not have electronic contacts and communicate the aperture information to the camera. As such, the camera will never be able to tell what aperture your lens is at, hence the F--.

Q: 9. my Nikon D5600 only lets me shoot at f22 with this lens is there a setting so i can use all aperture ?

A: One of the options in the aperture ring is a red auto setting. You would need to set the aperture to that auto setting and then change the aperture via the camera.

Q: 10. Is it a full frame lens?

A: It is not. This only covers up to a Super35mm Sensor.
