The cross effect appears from single point sources. Other forms of light sources, e.g., cylinder shaped light like from fluorescent lamps, will not produce an effect. There are also cases in which large light sources prevent the cross effect from appearing clearly. In these situations, try to move further away from the interfering light source and try shooting again.
The strength of the light source, the focal distance and the aperture value have an impact on the cross effect.
If your image is too dark when shooting illuminations, try increasing the exposure compensation. On the other hand, should the image be too bright, try with a reduced exposure compensation.
Cross streaks can be seen better in dark background settings. Also, focusing on the light source makes for a crisper cross effect.
Depending on the conditions, a mesh shaped flare will occur (strong light sources and back lighting conditions).
Increasing the focal length towards the telephoto end will strengthen the soft effect.
Light rays might distort at wide angles.
When the aperture is reduced to around f/22, light rays may become dotted.
Under circumstances, the HOYA SPARKLE produces a meshed pattern over the blurred parts in your image.
