## Abstract

Folded Tele cameras comprising an optical path folding element (OPFE) for folding a first optical path OP1 to a second optical path OP2, a lens including N=8 lens elements, the lens being divided into three lens groups numbered, in order from an object side of the lens, G1, G2 and G3, and an image sensor, wherein G1 and G3 are included in a single G13 carrier, wherein G2 is included in a G2 carrier, wherein both the G13 carrier and the G2 carrier include rails for defining the position of G2 relative to G13, wherein the Tele camera is configured to change a zoom factor continuously between a minimum zoom factor ZFMIN and a maximum zoom factor ZFMAX by moving the G2 carrier relative to the G13 carrier and by moving the G13 carrier relative to the image sensor, and wherein an effective focal length (EFL) is 7.5 mm<EFL<50 mm. The G2 carrier may be positioned by a lens transporter within the G13 carrier at a particular zoom factor to form a lens pair to enable optical investigation and/or transporting of the lens pair.

## Claims

### Claim 1

A lens transporter, comprising:
a preload cover;
a fixture base;
wherein the lens transporter is operational to transport a lens which is divided into three lens groups numbered, in order from an object side of the lens, G1, G2 and G3;
wherein G1 and G3 are included in a single G13 carrier,
wherein G2 is included in a G2 carrier, wherein the lens is configured to change an effective focal length (EFL) continuously between a minimum EFLMIN and a maximum EFLMAX by moving the G13 carrier relative to the G2 carrier,
wherein the EFL is in the range of 7.5 mm to 50 mm,
wherein the lens transporter is operational to fix or define a relative position of the G2 carrier and of the G13 carrier at a particular EFL to form a lens pair, and
wherein the lens transporter is operational to enable optical investigation and transport of the lens pair.

### Claim 2 (depends on 1)

The lens transporter of claim 1, wherein the lens transporter includes a locker operational to fix the G13 carrier into the fixture base.

### Claim 3 (depends on 2)

The lens transporter of claim 2, wherein EFLMIN is in the range of 7.5 mm-25 mm and wherein EFLMAX is in the range of 20 mm-50 mm.

### Claim 5 (depends on 4)

The lens transporter of claim 4, wherein the mobile device is a smartphone.

### Claim 6 (depends on 1)

The lens transporter of claim 1, wherein the G13 carrier includes one or more grooves, wherein the fixture base includes a G13 groove locker operational to fix the G13 carrier into the fixture base.

### Claim 7 (depends on 6)

The lens transporter of claim 6, wherein the G13 groove locker includes four lockers.

### Claim 8 (depends on 6)

The lens transporter of claim 6, wherein EFLMIN is in the range of 7.5 mm-25 mm and wherein EFLMAX is in the range of 20 mm-50 mm.

### Claim 9 (depends on 8)

The lens transporter of claim 8, wherein the lens is included in a mobile device.

### Claim 10 (depends on 9)

The lens transporter of claim 9, wherein the mobile device is a smartphone.

### Claim 11 (depends on 1)

The lens transporter of claim 1, wherein EFLMIN is in the range of 7.5 mm-25 mm and wherein EFLMAX is in the range of 20 mm-50 mm.

### Claim 12 (depends on 1)

The lens transporter of claim 1, wherein the lens is included in a mobile device.

### Claim 13 (depends on 12)

The lens transporter of claim 12, wherein the mobile device is a smartphone.
