A first guide member having a first guide member axis is secured to the lens support, and a second guide member having a second guide member axis is secured to the first guide member. A first mobile carriage is slidably coupled to the first guide member and a first mobile lens cell having a first optical axis is secured to the first mobile carriage. A second mobile carriage is slidably coupled to the first guide member, with a second mobile lens cell having a second optical axis secured to the second mobile carriage. The zoom lens assembly further includes a third mobile carriage slidably coupled to the second guide member, with a third mobile lens cell having a third optical axis secured to the third mobile carriage. The first guide member axis and the second guide member axis are substantially parallel, and the first optical axis, second optical axis, and the third optical axis are substantially collinear with the assembly optical axis.
