Which Lensbaby is this post about? There are multiple models of Lensbaby, spanning around a decade of production. The newer models with multi-element, glass lenses are moderately sharp lenses, especially on crop-body d-slrs. THere was the OPRIGINAL Lensbaby, with a single-element lens. Then a later model, called 2.0, which had a multi-element lens and which was MUCH sharper and better-corrected, but still allowed hand tilting. Then there was a third model, the one with the three metal rails to position the lens for repeatable tilts for use in repeated shots, multi-exposures, HDR shots, or for repeatable effects, OR for use with video cameras or, later, d-slr video. Then there was a fourth model. Then a fifth model I believe, with accessory telephoto or wide-angle lens modules.
I own multiple Lensbaby models. When one buys them, buy them in Nikon mount; there is ZERO lens diaphragm automation with them, and none have CPU chips, so, you might as well buy them in F-mount, so that they can also be used on Canon EF cameras. I like the very first, original Lensbaby, and I often use it with a Nikon 1.4x tele-converter, and occasionally a 2x tele-converter. The Lensbaby is for the person who wants to shoot "effects" pictures, and has the artistic integrity and the courage of their own convictions to actually make a permanent commitment to an image in-camera, and not try and later come up with something decent by pushing the pixels around 5 or 10 times in hopes of making an image. So...that eliminates a LOT of people, most of whom are afraid to actually "commit" to any image in-camera, and always rely on Photoshop and the crutch of let's try and try and try until we get something decent...
But see, the real issue is this: The various Lensbaby lenses are specialty lenses that do not sell in high volumes, and are entirely different from the vast,vast majority of other lens types, so therefore, they are utter crap. Right? Ask anybody who doesn't like the Lensbaby models, and they will tell you that that is right.
