The only mouse I can think of that comes close to what OP is asking for is the Ikari optical. It is optical, it has pinky and ring finger support, but is otherwise very plain-shaped and not really ergonomic.
It also happens to be a popular mouse in competitive gaming. Even though the sensor is not the greatest despite being optical. --- I5 3570 | GTX 760 | FILCO Majestouch 2 tenkeyless | Zowie FK | Asus Xonar DGX | Kingston 120 GB SSD | Sennheiser HD 518 | Samsung S24A350H
