Domestic Huaxia 823 mechanical camera, I want to ask some questions about it. ....

Huaxia 823 camera is an ordinary 135 camera.

Its lens is 1: 2 with a focal length of 40 mm.

Shutter from 1 sec to 1/300 sec, with B door.

The focusing range is 0.8-∞, and there is double image coincidence (macula) autofocus.

Above the fuselage, there are a shutter button, a winding wrench and a winding crank.

There is a rewind button (rewind lock) under the fuselage.

This machine has one disadvantage: there is no photometry, and the choice of aperture and shutter depends on experience, which is a bit troublesome for beginners. It works well.

When taking pictures, the main operating parts of the camera are the three parts on the lens:

1, aperture

2. Shutter

3, distance, when you take pictures, you look in the eyepiece and rotate the distance ring by hand. You see that the two yellow images in the middle are aligned and the distance is right.

The lens focal length of this camera is relatively short (40mm), so its depth of field is relatively large, and the distance requirement is not high, so it can generally take clear photos.

Your biggest problem is exposure (that is, how much aperture and shutter to use), so I send you a paper exposure meter, which is in my space photo album.

You can download it, print it out with a printer, and then cut and paste it, as long as the small piece of paper in the middle can slide. This may help you.
