The CY-20 is a small manual flash that tilts up to 90° for bouncing off a ceiling. It costs about $19.
Basics only
A manual flash fires at the power you set on it. The camera does not adjust it, so you set the exposure yourself with power, aperture and ISO. The 2.5 mm PC port allows a cable connection.
Its rating
At 3.7 stars on 117 ratings, owners are less happy with it than with NEEWER’s Z160 SE, which costs less and has a rechargeable battery.

What people ask before they commit
Will it fit my Sony camera?
The seller excludes Minolta and older Sony anti-intercalation shoes. Recent Sony bodies with the multi-interface shoe take standard single-contact flashes.
What does GN20 mean?
A guide number depends on the ISO and the coverage the maker chose when measuring it. It cannot be converted into watt-seconds, and neither figure is the light that reaches the subject.
How do I set exposure?
A manual flash fires at the power you set on it. The camera does not adjust it, so you set the exposure yourself with power, aperture and ISO.
