No I'm referring to the actual lense piece in front of the sensor
You can see it in this picture someone else took: http://i.imgur.com/7tjjEsA.jpg
In that picture, the inlet overall is perfectly centered on the "nipple" on the bottom of the sensor's IC. Said "nipple" has a pinhole directly in the center so that only the tracking surface significantly effects the sensor's image acquisition area. However, in the lense, the smooth clear "actual lense piece" is totally not in the center at all.
On other mice this is centered or nearly centered, so the only thing that affects the skew of the cursor's sensor as you lift it is the way the lense may shift around during operation, thus offsetting the "actual lense piece" but the lense is still able to get put into a position where it doesn't do this.. On the 332X (including the abyssus V2) this is totally not in the center at all, which give the sensor an inherent
z-axis bug, in direct correspondence with the design, because the central pixel of the tracking surface literally must
move on the sensor's acquisition area because optics 101.
I'm pretty sure they did this to reduce the amount of vertical space the sensor takes up without affecting the depth of field but it's still really bad. (my 3310 lense lets my 3320 kind of track, but it doesn't fit. and modifying the 3320 lense so that it fits with the "actual lense piece" centered on the pinhole causes it to stop tracking, probably defocusing due to being closer.)Edited by wareya - 10/26/16 at 3:47am
