An electronic device comprises an adjustment unit for adjusting a focus distance of a lens unit and obtainment unit for obtaining, from the lens unit, first information relating to a first range and second information relating to a second range. The first range being a focus range of the lens unit, and the second range being a focus range, in the first range, in which adjustment by the adjustment unit is limited. The electronic device controls, on the basis of the first information and the second information, the display device so as to display the first range and the second range to be distinguishable from each other.

An electronic device communicates with a lens unit whose focus range is a first range between a first position and a second position of a focus lens. The electronic device obtains first information indicating a third position of the focus lens, at which the focus distance of the lens unit infinity, and a second range between the third position and the second position of the focus lens. The electronic device controls, on the basis of the first information, a display unit to display the first range and the second range of the focus lens to be distinguishable from each other.

A finder includes, in order from an object side to an eye point side, an objective optical system that forms an intermediate image, and an ocular optical system that is provided for observation of the intermediate image. The intermediate image is positioned on the optical path between the objective optical system and the ocular optical system. The finder includes a plurality of reflecting surfaces for forming an erect image, and each of the objective optical system and the ocular optical system has at least one of the plurality of reflecting surfaces. The finder satisfies a conditional expression: 2<fo/fe<8 regarding a focal length fo of the objective optical system and a focal length fe of the ocular optical system.
