Lensbaby Composer Pro
If mirror-less camera owners were a bit peeved that it was dSLR users who were getting all the fun with Lensbaby lenses, they need feel hard done-by no longer. Lensbaby Composer Pro lenses are now available with a heap of mirror-less camera-compatible mounts. From Lumix G-series cameras to Olympus PENs, via Sony NEX and Samsung NX, they can all enjoy some tasty tilt-shift-tasticness.
The Composer Pro ships with the 50mm Double Glass Optic installed; it creates a sweet spot that's in sharp focus, and you get to decide where by playing around with the tilting and swivelling lens body. However, the Composer Pro is compatible with all of the optics in the Lensbaby Optics Swap System, including the Edge 80, the Sweet 35, and the Fisheye, so opportunities abound for getting creative with your images.
If you're wondering about the aperture on a Lensbaby lens, the Double Glass Optic has a maximum aperture of f/2.0. By removing and inserting different sized aperture disks, you can change to f/2.8, f/4.0, f/5.6, f/8.0. f/11, f/16, and f/22.
Time to go buy one? They're retailing around $300 and are available from authorised Lensbaby retailers and their own online store.
