+Trey Ratcliff walk) are when I am using the Lensbaby composer on my camera. These questions have come both from members of the walk and passers by.
The Lensbaby composer system is easy to explain but difficult to understand, it is a low-tech lens with a sweet spot of focus in the center, the size of the spot varies depending on the aperture used, and the spot can be moved around the frame by tilting the lens which has a ball and socket design.
The core optics of the lens can be removed and replaced with a different one, so far I have the 'plastic', 'single glass', 'double glass', and 'pinhole'. Others are available. Each optic gives a slightly different look
So why bother? It's something a little different, it's something fun, and with practice you can get some fantastic images with one. They are available from most good camera stores, or online. Not everywhere stocks them, I do recall a fantastically bemused look by the assistant in Ted's cameras upon being asked if they had Lensbaby, rather than try and convince him that they do exist, and are actually on their pro website, I decided to purchase elsewhere.
