Raises hand timidly...my fave is still the Lensbaby original, used with a 1.4x Nikon TC when on a crop frame camera. It has the more blurred, less-sharp look that I want, at every aperture, and is easier to focus, and it has a LOT more chromatic aberration, which makes the pictures look, well, toy-lens like and dreamy. On high-key stuff, like the classic daisy in a meadow Lensbaby stuff, the original is the best, IMHO. I actually like the original Lensbaby for what it is **not**.
The Lensbaby 2.0 is/was MUCH sharper in the center, and depending on the f/stop ring installed, has VERY blurry edges, down to pretty blurry edges, and frankly, I think software is easier...it just does not mess the image up enough. It's too sharp for my taste, and I find the focusing is very hair-trigger. When I was using the 2.0, I found that and I blew a LOT of shots with the 2.0 due to missed focus. Bonnie just bought a used 2.0 and found that she did okay with it if she just sort of snap-shot once the focus looked good. Once sales of the original petered out, the 2.0 was premiered with a new sharer lens, and the magnetic aperture discs, which was an improvement. But the increased sharpness kind of ruined it for me.
The third one was with the steel rods, and the lockable focusing and positioning, which allows video, AND long-exposures or bracketed shots. I bought it used at a bargain basement price, experimented with it for about maybe a week, and have set it back in the box for like 5 years...that model gave way to the new "Composer", and others. I found the steel rods and positioning system a MAJOR PITA, and it's obvious why this model was short-lived and the Composer series was developed to do the same thing, only easier, better, and more reliably. I was keen on the semi-permanent ability to get the thing "set up right", but I never really did develop an affinity for this one either. I stopped there. That must have been seven years ago now.
