Follow-up from the previous discussion of Wide Lens for our DB.
Here is an image taken with Nikon 14-24 on a 36x48 sensor.
The equivalent focal length (135 std) should be as wide as 11~12mm. [rectilinear not fisheye]

There is no magic. Just use the True Wide.

--- The attached photo is ONE SHOT - NO stiching.

There is NO Aperature Control ring for the NK14-24 f2.8.
The optimal optical quality for the NK14-24 should be about f5.6~f8.
I apply adehsive tape on the rear aperature control lever to shrink the aperture.

#5 - OM35 is a shift lens with larger image circle. It is adequate to cover 36x48 sensor (without any shift).
PS. This one is take with Aptus22. The previous is taken with !32C.
