It is well-known that it's hard to focus without viewfinder, in other words manually. In manual mode, lenses made for the camera usually base on the information of camera's autofocus system. But using the adapter doesn't let the camera suppose that the lens is the part of the whole system so this way is not useful. Device of confirming focus needs to be constantly joined to the adapter so that it could inform the camera if the subject of shooting is in focus.

Described device looks like a plastic plate provided with contacts. Attached to the peleng lens, it sends to the camera the information concerning to focal distance and aperture. You can choose your own settings but there are pre-installed default ones: 1:3,5 for the diaphragme, 8mm for the focal distance.

Focus confirmation device usage replaces confirmation from autofocus lenses designed specially for Canon cameras and fills up EXIF data with the information about exposition.

Principles of work:

1. Choose M or AV mode

2. Focus manually until the moment when the signal of confirmation will be send. Sometimes half-pression of the button of shutter is needed.

3. Close the diaphragme as it is demanded by settings. If you chose AV-mode, the speed of shutter will be set automatically.

4. Press the shutter release. Your shot is ready.
