Why can't I press the shutter after mounting the lens (An error page display)?

Since there are no electronic contacts to recognize the lens, please do Enable the "Release w/o lens". After enabling the "Release w/o lens" and switching to M, it will work normally.

Why does my picture out of focus and very blurry?

For manual lenses, you must turn the focus ring on the front of the lens to focus. If the photo is still blurry after focusing sharply, please adjust the exposure by ISO/aperture/shutter speed.

Why it show "F--"? and How to adjust the aperture value?

Manual lenses do not have an electronic contact, "F--" is displayed because the camera is unable to acquire aperture information. For manual lenses, the aperture value can only be adjusted with the aperture ring on the lens.

How to do if the image turns out dark?

If the image is too dark, increase the ISO (e.g. from 800 to 1600) to increase the sensitivity, and decrease the shutter speed (e.g. from 1/250s to 1/125s) to allow more light onto the sensor.

How to do if the image turns out bright?

If the image is too bright, lower the ISO (e.g. from 200 to 100) to reduce the light sensitivity, and increase the shutter speed (e.g. from 1/125s to 1/250s) to reduce the exposure and avoid overexposure.
