I have to admit that after reading some responses both here and elsewhere on the net, I am a bit confused. People seem to ohhh and ahhh when certain deliberate effects and methods are tried in photography, but immediately discount a lensbaby as a gimmick. I am sure that if these were first marketed 150 years ago, they would be totally acceptable.
My intention, if I do end up getting one, is it will be just another tool to use when photographing cars and bikes. I have come across a photographer on Flickr is doing wonderful things with a Lensbaby Muse at rod shows, which quite frankly, has inspired me.
Thanks for the feedback on the Muse Vs Composer. I'll keep that in mind when choosing which way I go (if I do bite the bullet).
