It did let me shoot very near to the subject, but there's a lot of barrel distortion
, resembling a fish-eye lens.
This is also known as barrel distortion
and, for obvious reasons, is a characteristic that many portrait and lifestyle photographers try to avoid.
In this paper the radial distortion with its type will be addressed, the barrel distortion
which appears in lenses of short focal lengths and the pincushion distortion in lenses of longer focal lengths, as the other types normally have less significant impacts than the radial [7-9].
For the images acquired with the zoom lens, I corrected for barrel distortion
using a third-party plug-in.
Electronic Image Stabilization (EIS) and Barrel Distortion
Furthermore, the exchange of information between the i-CS lens and the camera, enables easier formatting of Electronic Image Stabilization (EIS) and Barrel Distortion
Correction (BDC), which reduces the time needed for setup.
There was some minor barrel distortion
in the vertical plane on 1x but this went away as the magnification was increased.
Theia Technologies Linear Optical Technology enables an ultra-wide field of view without barrel distortion
through all-optical distortion correction, and without using software.
The most common distortion caused by the lens, is, in this case barrel distortion
that results from fitting the image in a smaller space.
I like how this corrects barrel distortion
for the lenses I use, so I actually bake it in as an Import preset, such that it is applied as I import my images.
Deformation of 2D barcode image includes barrel distortion
caused by the image acquisition device itself.
