The Lensbabies Lensbaby 3G works on the same principal as the Lensbaby 2.0, but also allows you to lock the lens into place once you have found your "sweet spot" of sharp focus and then to do fine focus adjustments. It is the ideal tool for photographers who require precise focusing, complete control, longer exposures, and repeatability.

When working with dynamic subject matter you can focus the Lensbaby 3G by compressing and bending/tilting the lens. For studio or static subject matter, you can lock the lens in place simply by pressing a button on the focusing collar. Then you can fine focus using a traditional barrel focusing ring and fine tune the tilt to place the sweet spot exactly where you want.

The Lensbaby is a hybrid between a bellows camera and a tilt-shift camera. The lens can be compressed, extended, and/or bent off-center in any direction for different effect. It will add a unique perspective on the world that is a radical departure from the precision of digital or even film photography. Effects like blurring, glowing highlights, and subtle, prismatic color distortions can all be achieved without software manipulations.

The optics in this medium format Lensbaby 3G are optimized for the Pentax 67 camera body.

The lens tubing can be compressed or extended by pulling or pushing the focusing collar at the end of the Lensbaby. This in turn controls what is in focus, with fully compressed focusing on infinity and full extended focusing about 1 foot ahead. To focus on subjects that are between these distances, you have to partly compress the Lensbaby.

The lens aperture can be changed by inserting different size magnetic aperture discs.
