Lensbaby 2.0 Pentax K Mount SLR Camera Lens (LB2PK)
 
The Lensbaby 2.0 SLR lens is the slightly more refined descendant of the Original Lensbaby, featuring a sharper optic, a new f/2 aperture setting, and magnetically levitating aperture disks. Lensbaby 2.0 features a low dispersion, high refractive index, multi-coated optical glass doublet which is capable of delivering images with a tack sharp sweet spot of focus with minimal diffusion even at the f/2 aperture setting. 
Customer Review: Creative
I've got this lens for about a year now. I haven't used it that much lately, but every time i do i have lots of fun. You get creative immediately. If you don't have an external meter, you will learn a thing or two about photography also cause this lens doesn't communicate with the camera (at least with mine... Nikon D80). It's a great way of getting the feel for light and f/stops. So either if you get it for the extremely selective focusing, crazy creative fun or learning a little bit more about light. I highly recommend it. 
Customer Review: Definitely adds fun to your photos!
I'm a huge fan of tilt shift photography and this makes it so easy- good for newbies and pros alike. I bought it to use with my Olympus e-500 and it works great! Takes a little getting used to- but once you get a hang of it - it's a lot of fun to use! I've been comparing photos I've taken with it to ones I took with a regular SLR (same shots)- and the lensbaby certainly makes an ordinary photo more interesting. It's light and fits nicely in my camera bag. Comes with a little fabric bag to store it in. Instructions are easy- but just to note- in English only. If you really want to have more fun with your photo taking- This is a great way to do it. I wish it came with a sun filter to protect the lens. Not sure if they make one for it or not.
