The Lensbaby Wide Angle/Telephoto Kit...
Lensbaby 3G, Lensbaby 2.0, and The Original Lensbaby all feature a 50mm fixed focal length. The Lensbaby 0.6X Wide Angle Conversion Lens and the 1.6X Lensbaby Telephoto Conversion Lens allow photographers to change the effective focal length to either 30mm or 80mm respectively be screwing the conversion lenses onto the front of their Lensbaby lens.
The Lensbaby 0.6X Wide Angle Conversion Lens has a unique optical design that widens the field of view while keeping the size of the Sweet Spot constant relative to the size of the photo.
Standard wide angle conversion lenses shrink the sweet spot when used with a Lensbaby. The Lensbaby Wide Angle/Telephoto Kit is compatible with all Lensbaby lenses.
