15mm fisheye on Mark IIN

[meethil]

Hi,

Does anyone know what will happen when i use a 15mm 180 degree Fisheye lens on a Mark IIN which has a 1.3 conversion factor?

Do i still get fisheye like a 19.5mm fisheye lens or does it just become a 19.5 or 20mm wideangle lens?

If anyone has some definitive idea please let me know.
Thanks a lot.

A fisheye by any other name (or crop factor) is still a fisheye.;)

you will still get the usual distortion, just with a lesser effect because the most distorted areas (corners) will not show on the cropped sensor.

i'm using a 15mm diagonal fish on a 1.6x crop BTW. on the cropped sensor it still equals a FOV of about a 17mm non fisheye lens.
