Reminiscent of the very first Lensbaby lens, the Spark 2.0 is a flexible lens body designed for use with Canon RF-mount cameras and to be used in conjunction with the Optic Swap System. This Spark 2.0 is delivered with the Sweet 50 optic, which provides a clear sweet spot of sharp focus that is surrounded by a smooth blur, which can be adjusted depending on how the lens body is positioned. The Spark 2.0's accordion-like design permits nearly unrestricted tilt range, up to 30° in any direction, and requires the distinct squeeze-to-focus movement to manually adjust focus. The Spark 2.0 and Sweet 50 combination also avails an f/2.5-22 adjustable aperture range, 12-blade diaphragm, and a minimum focusing distance of 1.1' for working with close-up subjects.

• Canon RF lens mount.
• Flexible, accordion-like body design resembles the Original Lensbaby from 2004 and enables tilting the optic up to ~30° in any direction.
• Unique squeeze-to-focus, squeeze-to-tilt design requires a fun "dance-like" process of achieving sharp, selective focus with creative distortions and blur.
• Accepts various optics from the Optic Swap System.
• Permits focusing as close as 1.1' away.
• Metal lens mount for improved durability and rigidity.

• Normal 50mm focal length provides a comfortable and natural field of view.
• Unique rendering delivers a precise sweet spot of focus surrounding by a characteristic blur. The quality, sharpness, and size of the in-focus area can be controlled by adjusting the lens body.
• Besides adjusting exposure, the f/2.5 to f/22 aperture range can also be used to adjust the size of the sweet spot of focus.
• A 12-blade diaphragm contributes to a smooth, pleasing bokeh quality.
• Doublet lens construction uses two elements in one group, and both elements have a broadband, anti-reflective multi-coating to resist flare and ghosting for increased contrast and color accuracy.

Q: 2. I have a canon eos 70D. What else would i need in order to use this lens?

A: The Sweet 35 optic is an insert that is used with a Lensbaby lens. Basically anything labeled as an optic from Lensbaby is a lens that inserts and locks into the lensbaby mount/lens. You only need one mount then almost any optic will fit. For more information about the Lensbaby system you should search for them and look at the Compser or Muse without an optic.You can also buy and other Lensbaby from B&H, such as the Sweet 50 and the Sweet 50 optic can be removed and the Sweet 35 inserted into thta base.The Canon 70D uses the APS-C format so the image area is smaller than a full frame (such as the 6D). This will crop out the edges so the effect may not be as controlable as with a full frame. The APS-C works to our advantage when using a telelphoto because it only uses the center of the image so in effect magnifies the image. However it works against us when using a EF wide angle lens. The EF lens might be rated at 35mm but your field of vision in the cmaera is more like 50mm. This is also true with the Lensbaby. It is and EF so works best on a full frame. If you want a good wide angle look for EF-S lens. Then a 35mm wide angle lens is a true 35mm.I learned these lessons the hard way.
