The Atoron is a superb shooter, and Yashica (Tomiinon) had plenty of experience with submini lenses on early cameras, such as the Y16.
The metering system on the Atoron is fine, as long as the selenium meter still works. For manual control, you have to like working with the EV scale.
For anyone wishing the Atoron had a focusing lens, there is the Atoron Electro model -- which also adds a more sensitive CdS meter, but unfortunately drops any manual adjustment (except for the film speed).
