A story on msn.com (New Top 10 Tech Items?) the other day showed an interesting set of Fisheye, Macro, Wide Angle and Telephoto Phone Lenses (3 lenses) available online from photojojo.com for $49. Has anybody on the Forum bought these yet and used them? What do they think of them? Do they work OK with a hard case (i.e. do they mount on the case or do they have to mount directly on the camera?).
