Abstract

A film-loading type camera comprises an exposure setting unit setting an exposure condition. The exposure setting unit carries out an exposure compensation of not less than +1.5 EV for a photometric value when the camera is loaded with a film of a film speed with which a system sensitivity defined as Ls in the following equation is not more than a specific value: Ls = 5-log2 (S/3.125)-log2 T0 +2⋅log2 F0. In the equation, S is an arithmetic expression of the ISO speed of the loaded film, F0 is an f-number at full opening of the camera lens, and T0 is a maximum shutter speed in second.
