Lensbaby Composer Pro II

No, the Composer Pro II is a fully manual lens. You will need to manually adjust both the focus ring and the tilt angle to achieve your desired effect, as there is no electronic communication with your camera body.

Yes, it is compatible with both sensor formats. Keep in mind that the effective field of view will change depending on your camera's sensor size, appearing wider on full-frame cameras and tighter on APS-C models.

The Optic Swap system means the lens housing is modular. You can remove the internal optic and replace it with other compatible Lensbaby optics to change the look and style of your images without needing to buy an entirely new lens housing.

No, the Composer Pro II is not weather-sealed. You should take care to protect it from rain, dust, and extreme humidity, especially since the tilt mechanism involves moving parts that are exposed.

It requires practice. Because the focus is manual and the tilt angle is adjustable, it takes time to develop the muscle memory to place the 'slice' of focus exactly where you want it, but the tactile control makes the learning process very intuitive.

No, this lens does not feature built-in image stabilization. Since it is a manual focus lens, you will need to rely on steady hands or a tripod, particularly when shooting at slower shutter speeds.
