Q: Questionwhat does it come with?

Asked 8 years ago by pepper.

• A:Answer The lens and a lens cap. We already had the camera and starter lenses that came with our camera. We also purchased a new camera bag to hold everything for safe carrying as well as separate purchase insurance against accidental damage. By the way the pictures are now amazing. Hope this helps.

Q: QuestionWill this fit my Canon EOS M50? If adapter is required what kind?

Asked 5 years ago by Beth.

• A:Answer This is a full frame Canon EF lens. To work on an EOS M camera you need the $170 EF-M adapter, as it is a completely different mount.

  I would recommend:
