摘要： An objective lens system includes a first lens group having a focal length F1 for focusing, a second lens group, which is a system of magnification variation having a focal length F2, a third lens group for compensation and having a focal length F3 and a fourth lens group having a focal length F4. The first lens group has a positive first lens assembly with a focal length F1a and a negative second lens assembly with a focal length F1b. The third lens group ensures an image point of the second lens group falls within the focal length F3 thereof. The first, second, third and fourth lens groups commonly form a finite conjugative system of magnification variation. Moreover, the objective lens system, as a whole, has a negative focal length.

摘要： Systems and methods for facilitating electronic transactions via a device capable of communicating with a network. The method includes providing a catalog on the network and communicating with the network via the device. The catalog is downloaded to the device and communication is discontinued with the network via the device. At least one desired transaction within the catalog is selected and stored on the device. The device recommunicates with the network and the at least one desired transaction is completed.
