- Aperture settings are limited to 2.5, 3.2, 4.0, 5.0, 7.0, 11.0 and 22.0 (nothing in between).
- The origin (OEM) of this lens is unknown. So far rebadges have also been released by Opteka and Vivitar.
- The Opteka is reported to be of rather cheap quality (chromatic abberation/purple fringe, bad bokeh and stuck apertures after few times in use).
- Kelda is the house brand of UK based distributor Kauser International. They sell rebadges of the usual current suspects, but claim to buy them from China based company called Changchun Kaili Optronics Co., Ltd.. However, the rebadges are yet to be confirmed as none of the provided product pictures actually show the lenses branded as Kelda (or Kaili).
