The Lensbaby Sweet 50 Optic is made for use with the Composer Pro, which can be bought separately, or used interchangeably with the Sweet 50 if you own it already with a different optic. It is a selective focus lens that uses a curved field of focus optic to create a blurred effect around the focus spot.

The 50mm focal length lens has two multi-coated glass elements in one group, and an aperture range of f/2.5 to f/22. The 12-blade internal aperture is easily controlled via a ring on the front of the optic. The sharp sweet spot of focus can be moved within the frame by tilting the Composer Pro's ball-and-socket joint. The size of the sweet spot is also controlled by changing the aperture.

Q: 7. How much smaller is the focal plane of this lens on a crop sensor camera than it is on a full frame camera?

A: A 50mm lens on a Canon crop sensor camera would be roughly equal to using an 80mm lens if you are comparing it to 35mm film or a full frame sensor camera. It does not matter if it is a Lensbaby 50mm or a Canon 50mm or a Canon 18-55mm set to the 50mm range. They will all have the same focal length.

Q: 8. I have the composer pro ii in both canon and fuji mounts, and in both the lens is very hard to tilt even with the ring loosened. is this normal?

A: I've not experienced trouble of this kind. It looks as if Lensbaby are offering to take them back for a fix if your problem persists. But it seems odd that you have the problem for both mounts (I assume two Lensbabies). Seems like you need to undo the tension ring, that is not the front silver ring which operates focus. It is the ring closest to the camera that needs to be turned anti clockwise.

Q: 9. This Lens works with eos m3 ...? Antonio de la rosa
