Can anyone explain to me what haze in a lens is. I've this lens which seems to p erform well; however, I was looking into it with a magnifying glass, and it is h azy. The haze seems to be on the back side of the front element. If not haze, an d I don't know a lot about lenses, it seems like foam looking through the back o f the lens. From the front, it's hazy looking to me. And I wonder if this, whate ver it is, has the effect of a soft-focus filter. I mean, until I discovered tha t there was something wrong with this lens, I liked its performance, and now I w onder if it's possible the haze was producing somekind of effect on the tonality . If anyone has any experience with this please let me know. Thanks.
