This Pentax 05 telephoto toy camera lens is sure to generate curiosity in anyone interested in new ways to explore the artistic side of photography. While a great many digital cameras built in the past few years have creative filters that approximate the look of the toy film cameras of yesteryear, this lens actually gives the Pentax Q an old-school analog front end that sees the world the same way those toy cameras did. Yes, your results are unpredictable, but that's part of the fun of discovering what these lenses can do.

The Pentax 05 is the telephoto version of this toy camera concept lens. It has a 35mm equivalent of 100mm, and is an excellent length for shooting portraits (with enough light) and shooting outdoors.
