So on another post on the forum related to this lens, Zayne12 asked about whether Kase filters added any additional aberrations when pointed into the sun. I hadn't experimented with it myself, so I went out to a location I had previously shot some pictures of without the Kase filters and shot them again with the Kase filters. There does appear to be additional aberrations when pointed into the sun. However, not having direct comparison shots from the same spot on the same day, I had to wait for another sunny sunset in Denver before I could take back to back images with and without one of the Kase filters.
The first image is tonight's sunset without any filter. The second is with an ND64 Kase filter. I apologize for the slight change from 14mm to 15.2mm. I inadvertently moved the zoom ring after inserting the rear filter.
Anyways, just something to be aware of if you're planning to use this lens and rear Kase filters while pointed into the sun.
