LensBaby Composer for Canon EF brand_Lensmate This is a genuine LeitzThe Lensbaby Composer is a tiltable lens on a ball socket for playing with focus, not a "real" tilt shift lens. So if you're looking for a toy, you won't be disappointed; if you just threw away your old fashioned 4x5 because it uses obsolete "film" and the future is digital and you're looking to replace it with this, you better hope the garbage trucks are running late this morning. Anyway, the optics are in good condition, and socket moves smoothly.
