How to Use Star Focus Filter(video)?
Method 1
-
Mount the Star Focus Filter onto your camera.
-
Turn on the live view mode, adjust the ISO to the biggest (ISO 1600 or above), and set the shutter speed to 10s or more.
-
Adjust the frame and make sure the bright star or light source is in the middle of the frame. It is recommended that you look for a bright star of magnitude 1 to focus on.
-
Magnify the frame and adjust the focusing rings at the same time until three fine spike lines show out in the frame.
-
Rotate the focusing ring to make the three spikes intersect at one point. This the when the precise focus is achieved.
Method 2
-
Mount the Star Focus Filter onto your camera.
-
Adjust the focus rings to get an infinity focus
-
Set the high ISO and short exposure (several seconds), and take one testing shot
-
Check the three spike lines in the frame, if the central spike is closing to the left, screw the focus ring to the right. If the central spike is closing to the right, screw the focus ring to the left.
-
Take a second testing shot, and repeat step 4 until three spikes intersect at one point. Then a precise focus is achieved.
Note: Hand holding the filter, then it can work with the lens without the adapter
Tips:
-
It will need to position the bright star in the middle of the frame, choosing the bright star of magnitude 1 or close to the magnitude 1
-
For the wide lenses, please turn the aperture to the biggest
-
The filter is not wear-resistant, please store it in a filter case after use. If there is dust or oil, please use an air blower and neutral detergent to remove them
-
Do not place it in high temperature environment
