Sony Ericsson Xperia ray - Accidental Camera Tip

Ok, my movie playback review is long over due (that's still coming up)... but I've been playing with the camera of the ray in more situations and this may interest some readers.

I've found that when a bright light source is hitting the ray from the side (effect is more pronounced if the light source is coming from the left - where the lens is closer to the edge) there's very slight ghosting visible in the photo.  You can simply change the angle you shoot at, cup your hand over the lens, or make a very small/short lens hood.  The X10 Mini Pro didn't have this problem as the lens was recessed further into the body.

I made a crude one out of electrical tape, just to see if it would work.  The cleanest way I've found is to get a cone shape slope as close to the lens as possible (reverse of a regular lens hood) to minimize the visual change in the phone.

Slight ghosting visible on the upper left

With the lens hood, slight improvement

My initial idea was to blacken out the silver ring

Electrical tape

Cut a hole slightly smaller then the silver ring

Tweezers make the job a lot easier

The tape slopes and floats a little above the lens


Extending the lens hood to about 1-2mm improves the effect, I'm guessing a small rubber O-ring would do the trick as well.

Over-all I decided to remove my lens hood despite the effect simply because I felt is was only in certain lighting conditions that it had an effect.  YMMV, so you may choose to improve on this concept or ignore it all together.  Just wanted to share my discovery.
