Ask the photographer again; FM- 10 is better!

Of course, 1 need not be placed in the middle. You know, in the viewfinder, the focus of the frosted part and the cracked part is the same, the cracked part is in focus, and the frosted part is definitely clear, and vice versa. However, the frosted part is more convenient, which can be used for quick focusing, and the segmented image part is more accurate, which can be used for precise focusing. However, compared with the frosted part, it is inconvenient to observe and may be slower-sometimes the two semicircles of the segmented image will be one bright and one dark!

No matter where he is in the viewfinder, just turn the focus ring and the image will be clear.

On cloudy days, the light is cold and the contrast is small, so it is impossible to be as bright as on sunny days. Digital can adjust the white balance to improve color, but film can't.

4 Flash index. It's upstairs. In addition, in practice, it is necessary to open the aperture one level higher than the standard calculation value. Due to depreciation, exaggeration, callback time (the interval between flashing and the next flashing, the indicator light is not flashing enough) and other reasons, the flicker amount is discounted, which is not enough for the nominal index.

In automatic flash mode, set the lens aperture to predetermined positions, such as F4 and F8, and the flash will automatically provide appropriate exposure. Of course, the flash must have this function (with a small "electric eye").

If I remember correctly, the metering of FM 10 is three lights and five states, which can indicate five metering results: underexposed, slightly underexposed, normal exposed, slightly overexposed and overexposed. According to the films with different dry sensitivities, the corresponding accurate photometric effect can be obtained, which provides reference for shooting.
